In 2020 the U.S. produced more than 16 million barrels of petroleum per day (mmbd), or 18.2% of
the world’s 88 mmbd.
The U.S. consumed 20.5 mmbd, or 20% of the world’s 100 mmbd in 2020.
Net imports of petroleum to the U.S. in 2020 were -0.65 mmbd meaning the U.S. exported more
petroleum than it imported.
Petroleum use in U.S. transportation comprised 66% of total U.S. petroleum use in 2020.
In 2020, U.S. transportation petroleum use was 73% of total U.S. petroleum production.
Petroleum comprised 90% of U.S. transportation energy use in 2020.
Cars and light trucks accounted for 63% of U.S. transportation petroleum use in 2019.
Medium trucks (Class 3-6) accounted for 4% of U.S. transportation petroleum use in 2019.
Heavy trucks (Class 7-8) and buses accounted for 19% of U.S. transportation petroleum use in 2019.
Nonhighway modes accounted for the remainder of U.S. transportation petroleum use in 2019
(14%).

In 2019 there were 109 million cars and 144 million light trucks in the U.S. (253 million total light
vehicles).
Light vehicles accounted for 90% of the 3.3 trillion vehicle miles driven in the U.S. in 2019.
The average age of a U.S. light vehicle was 12.1 years in 2020.
U.S. cars:
o 3,402,000 cars were sold in 2020 which was 23% of new light vehicle sales.
o In 2019 the average fuel economy for the U.S. car fleet (all cars on the road) was 28.3 mpg.
U.S. light trucks:
o 10,712,000 light trucks were sold in 2020 which was 72% of new light vehicle sales.
o In 2019 the average fuel economy for the U.S. light truck fleet (all light trucks on the road) was
20.4 mpg which was 7.9 mpg lower than the average for cars.
The average U.S. household vehicle travels 11,200 miles per year (2017 NHTS).

Heavy Truck Characteristics

ABSTRACT
The Transportation Energy Data Book: Edition 40 is a statistical compendium prepared
and published by Oak Ridge National Laboratory (ORNL) under contract with the U.S.
Department of Energy, Office of Energy Efficiency and Renewable Energy, Vehicle Technologies
Office. Designed for use as a desk-top reference, the Data Book represents an assembly and
display of statistics and information that characterize transportation activity and presents data on
other factors that influence transportation energy use. The purpose of this document is to present
relevant statistical data in the form of tables and graphs. The latest edition of the Data Book is
available via the Internet (tedb.ornl.gov).
This edition of the Data Book has 13 chapters which focus on various aspects of the
transportation industry. Chapter 1 focuses on petroleum; Chapter 2 – energy; Chapter 3 – highway
vehicles; Chapter 4 – light vehicles; Chapter 5 – heavy vehicles; Chapter 6 – alternative fuel
vehicles; Chapter 7 – transit and other shared mobility; Chapter 8 – fleet vehicles; Chapter 9 –
household vehicles; Chapter 10 – nonhighway modes; Chapter 11 – transportation and the
economy; Chapter 12 – greenhouse gas emissions; and Chapter 13 – criteria pollutant emissions.
The sources used represent the latest available data. There are also two appendices which include
detailed source information for some tables and measures of conversion. A glossary of terms is
also included for the reader’s convenience.

INTRODUCTION
In January 1976, the Transportation Energy Conservation (TEC) Division of the Energy
Research and Development Administration contracted with Oak Ridge National Laboratory
(ORNL) to prepare a Transportation Energy Conservation Data Book to be used by TEC staff in
their evaluation of current and proposed conservation strategies. The major purposes of the Data
Book were to draw together, under one cover, transportation data from diverse sources, to resolve
data conflicts and inconsistencies, and to produce a comprehensive document. The first edition of
the TEC Data Book was published in October 1976. With the passage of the Department of Energy
(DOE) Organization Act, the work being conducted by the former Transportation Energy
Conservation Division fell under the purview of the DOE's Office of Transportation Programs.
This work continues today in the Vehicle Technologies Office.
Policymakers and analysts need to be well-informed about activity in the transportation
sector. The organization and scope of the data book reflect the need for different kinds of
information. For this reason, Edition 40 updates much of the same type of data that is found in
previous editions.
In any attempt to compile a comprehensive set of statistics on transportation activity,
numerous instances of inadequacies and inaccuracies in the basic data are encountered. Where
such problems occur, estimates are developed by ORNL. To minimize the misuse of these
statistics, an appendix (Appendix A) is included to document the estimation procedures. The
attempt is to provide sufficient information for the conscientious user to evaluate the estimates and
to form their own opinions as to their utility. Clearly, the accuracy of the estimates cannot exceed
the accuracy of the primary data, an accuracy which in most instances is unknown. In cases where
data accuracy is known or substantial errors are strongly suspected in the data, the reader is alerted.
In all cases it should be recognized that the estimates are not precise.
The majority of the statistics contained in the data book are taken directly from published
sources, although these data may be reformatted for presentation by ORNL. Consequently, neither
ORNL nor DOE endorses the validity of these data.

As new technologies appear, and new areas are explored, the amount of proved reserves of crude oil and natural
gas has grown. Although the reserves of natural gas in the United States were 132% higher in 2020 than in 1980,
the U.S. share of world natural gas reserves is lower.

This table shows petroleum production, which includes both crude oil and natural gas plant liquids. Because other
liquids and processing gain are not included, the world total is often smaller than world petroleum consumption
(Table 1.4). The United States was responsible for 18.8% of the world’s petroleum production in 2020 and 14.9%
of the world’s crude oil production (Table 1.2).

During the 1980s and 1990s, the United States accounted for about one-quarter of the world’s petroleum
consumption, but from 2000 to 2012 that share had been decreasing. In 2018 the United States accounted for only
20.5%. World petroleum consumption decreased in 2008 and 2009 but has continued to increase thereafter. NonOECD consumption has continued to increase.

Note: Consumption for OPEC and Rest of World in 2020 are actually 2019 consumption, which are the latest
available. Total consumption is higher than total production due to refinery gains including alcohol and liquid
products produced from coal and other sources. See Glossary for OPEC countries.

The share of petroleum imported to the United States can be calculated using total imports or net imports. Net
imports, which are the preferred data, rose to over 50% of U.S. petroleum consumption for the first time in 1998,
while total imports reached 50% for the first time in 1993. OPEC share of net imports has been below 50% since
1993. Due to declining total imports and rising petroleum exports, net petroleum imports were negative in 2020
for the first time in the series.

More than half of the oil imported to the United States in 2019 was from North America. Canada and Mexico
provided most of the oil, plus a small amount from the U.S. Virgin Islands (not listed separately).

The Strategic Petroleum Reserve (SPR) began in October 1977 as a result of the 1975 Energy Policy and
Conservation Act. Its purpose is to provide protection against oil supply disruptions. The U.S. consumed 18.1
million barrels per day in 2020. At that rate of consumption, the SPR supply would last 35 days if used exclusively
and continuously.

Oxygenate refinery input increased significantly in 1995, most certainly due to the Clean Air Act Amendments of
1990 which mandated the sale of reformulated gasoline in certain areas beginning in January 1995. The use of
MTBE has declined over the last 15 years due to many states banning the additive. The other hydrocarbons and
liquids category includes unfinished oils, motor gasoline blending components and aviation gasoline blending
components.

When crude oil and other hydrocarbons are processed into products that are, on average, less dense than the input,
a processing volume gain occurs. Due to this gain, the product yield from a barrel of crude oil is more than 100%.
For the last 20 years, the processing volume gain has been about 5-7%.

Domestic petroleum production increased in 2009 for the first time in 20 years and reached an all-time high of 17
mmbd in 2019. Most of the petroleum imported by the United States is in the form of crude oil. Exports were at an
all-time high in 2019 as well, partly due to a lift of crude oil export restrictions in December 2015.

U.S. petroleum production has been mainly increasing and petroleum imports decreasing from 2009 to 2019.
Despite a slight decline in petroleum production in 2020, net imports of petroleum in 2020 were negative for the
first time in the series history. Transportation petroleum use as a share of domestic production went below 100%
in 2018 for the first time since the 1980's.

Before 1989 the U.S. produced enough petroleum to meet the needs of the transportation sector but was still short
of meeting the petroleum needs of all the sectors, including industrial, residential and commercial, and electric
utilities. In 1970 the gap between what the U.S. produced and what was consumed was about 3 million barrels per
day and in 2007, the gap was 12.8 million barrels per day. By 2050, there is no gap expected if petroleum and other
inputs are included or 1.6 million barrels per day if only conventional petroleum is used.

Figure 1.5. United States Petroleum Production and Consumption – All Sectors, 1970–2050

Notes: “Total U.S. Petroleum Production” includes crude oil, natural gas plant liquids, and refinery gains. It does not
include dry natural gas.
“Total U.S. Petroleum Production” is for all uses.
“Total U.S. Petroleum Production with Other Inputs” also includes non-petroleum sources such as ethanol,
biomass, liquids from coal, other blending components, other hydrocarbons, and ethers which were domestically
produced.
The change from historical values to projected values is between 2020 and 2021, except transportation which is
between 2019 and 2020.
The sharp increase in the value for heavy trucks between 2006 and 2007 is the result of the Federal Highway
Administration’s methodology change.

In 1989, for the first time, petroleum consumption for transportation surpassed total U.S. petroleum production,
which was declining. These contrasting trends in production and consumption created a gap that was met with
foreign imports of petroleum. In 2009, however, the U.S. production of petroleum (for all uses including, but not
limited to, transportation) began to increase substantially because of new hydraulic fracturing and oil extraction
technology. In 2015, total production exceeded all transportation sector petroleum consumption for the first time.
Transportation accounted for about two-thirds of all U.S. petroleum consumption in 2020.
The Energy Information Administration expects petroleum production to be greater than transportation
consumption through 2050. Including non-petroleum sources such as ethanol, the production will exceed
transportation demand by approximately 7.7 million barrels per day in 2050.

Transportation accounted for about 70% of U.S. petroleum use from 2008 to 2018, but declined to 66% in 2020,
likely due to less travel during the COVID-19 pandemic. Total petroleum use in 2020 was at the lowest level since
1995.

Although 19% of transportation energy use is for nonhighway modes, only 14% of transportation petroleum use is
for nonhighway. This is because some nonhighway modes, such as pipelines and transit rail, use electricity. An
estimate for the petroleum used to make electricity is included in the data. Table 1.15 shows highway petroleum
consumption. See Table 2.10 for nonhighway transportation energy use in trillion Btu.

Petroleum accounted for 33% of the world’s energy use in 2018. Although petroleum and natural gas are the
dominant energy sources for OECD countries, the non-OECD countries rely on coal and petroleum. The U.S.
shares of primary energy sources are similar to the OECD countries as a whole, but with a lesser reliance on
renewables and a greater reliance on natural gas.

In transportation, the alcohol fuels blended into gasoline to make gasohol (10% ethanol or less) are counted under
“renewables” and are not in with petroleum. The petroleum category, however, still contains other blending agents
that are not actually petroleum but are not broken out into a separate category.

Ethanol is an oxygenate blended with gasoline in amounts up to 10% to be used in conventional vehicles and is
blended in higher amounts up to 85% for use in flex-fuel vehicles. The production of ethanol grew to over 16 billion
gallons in 2018 but has declined each year since then. Beginning in 2010, the United States began exporting more
fuel ethanol than it imports. Biodiesel is a renewable fuel typically made from vegetable oils or animal fats. It can
be burned in standard diesel engines and is often blended with petroleum diesel. In 2020, about 1.9 billion gallons
of biodiesel were consumed.

Total transportation figures do not include military and off-highway energy use and may not include all
possible uses of fuel for transportation (e.g., snowmobiles). Only end-use energy was counted for electricity.
b
Due to changes in the FHWA fuel use methodology, motorcycle, bus, and heavy truck data are not comparable
with data before the year 2007. Car and light truck data changed after 2008; see Appendix A for car/light truck shares.

About 19% of transportation energy use was for nonhighway modes in 2019. Air travel accounted for 48% of
nonhighway energy use in 2019. See Table 1.16 for nonhighway petroleum use in thousand barrels per day.

The Environmental Protection Agency's MOVES model estimates fuel use for different types of nonroad equipment
and off-highway vehicles. MOVES nonroad base data were updated in model 2014b. Most of these vehicles/
equipment use diesel fuel. Recreational equipment, such as off-highway motorcycles, snowmobiles, and all-terrain
vehicles, are mainly fueled by gasoline.

The Federal Highway Administration (FHWA) cautions that data from 1993 on may not be directly comparable to
earlier years. Some states have improved reporting procedures in recent years, and the estimation procedures
were revised in 1994. The FHWA no longer publishes separate estimates of gasohol or ethanol used in gasohol.

Great care should be taken when comparing modal energy intensity data among modes. Because of the inherent
differences among the transportation modes in the nature of services, routes available, and many additional factors,
it is not possible to obtain truly comparable national energy intensities among modes. These values are averages,
and there is a great deal of variability even within a mode.

Great care should be taken when comparing modal energy intensity data among modes. Because of the inherent
differences between the transportation modes in the nature of services, routes available, and many additional
factors, it is not possible to obtain truly comparable national energy intensities among modes.

The top countries producing the world’s cars and trucks have changed over the last 18 years. In 2020, China was
the largest producer of cars and trucks. In 2000, Japan produced the most cars and the United States produced
the most trucks (includes light trucks). Car production in 2020 was less than in 2000 likely due to two reasons -sport utility vehicles becoming more popular than automobiles in some countries and the 2020 pandemic.

Use caution comparing historical data because of disconnects in data series and definitional differences among
countries. The United States uses light trucks (SUVs, minivans, pickups) for personal travel which are not counted
as cars in this table. China’s light trucks were not counted in this table until 2014, when a reclassification of vehicle
types added them as cars. The U.S. share of world cars continued to be below 12%. The growth in the World total
comes mainly from developing countries, like China, Indonesia, India, and South Korea.

Use caution comparing historical data because of disconnects in data series and definitional differences among
countries. The United States totals include SUVs, minivans, and light trucks, many of which are used for personal
travel. Thus, countries that only use trucks for freight movement will not be comparable to the United States.
China’s light trucks were included in this table until a reclassification in 2014.

VEHICLES IN USE
Both the Federal Highway Administration (FHWA) and IHS Automotive report figures on the car and
truck population each year. The two estimates, however, differ by as much as 11.2% (1981). The
differences can be attributed to several factors:
•

The FHWA data include all vehicles which have been registered at any time throughout the
calendar year. Therefore, the data include vehicles which were retired during the year and may
double count vehicles which have been registered in different states or the same states to different
owners. IHS Automotive data include only those vehicles which are registered on July 1 of the
given year and would not include vehicles registered after that date.

•

The classification of mini-vans, station wagons on truck chassis, and utility vehicles as cars or
trucks causes important differences in the two estimates. IHS Automotive data included passenger
vans in the car count until 1980; since 1980 all vans have been counted as trucks.

•

Starting in 1993, the FHWA reclassified some minivans and sport utility vehicles into the truck
category which were previously included with cars. This change produced a dramatic change in the
individual percentage differences of cars and trucks. The difference in total vehicles has been less
than 5% each year since 1990 and does not appear to be significantly affected by the FHWA
reclassifications. Beginning with 2009, the FHWA discontinued the car/2-axle, 4-tire truck
designations on Table VM-1. The data since 2009 come from Tables MV-1 and MV-9.

•

The FHWA data include all non-military Federal vehicles, while IHS Automotive data include only
those Federal vehicles which are registered within a state. Federal vehicles are not required to have
State registrations, and, according to the General Services Administration, most Federal vehicles
are not registered.

•

In 2012 both IHS Automotive and FHWA changed their methodologies for the car/light truck
split which created a significant decrease in the number of cars reported and a corresponding
increase in the number of light trucks.

In the early 1980's, researchers had to make a conscious choice of which data series to use, since they differed by
as much as 11%. In 2005 the two sources differed by less than 1%. Both sources changed their methodologies for
the car/light truck split causing significant decreases to the number of cars in 2012.

The graphs below show the number of motor vehicles per thousand people for various countries. The data for the
United States are displayed in the line which goes from 1900 to 2019. The points labeled on that line show data for
the other countries/regions around the world and how their vehicles per thousand people compare to the United
States at two different points in time, 2009 and 2019. For example, the graph shows that in 2009, Eastern Europe’s
vehicles per thousand people was about where the United States was in 1949, but by 2019 it is about where the
United States was in 1958. The lower part of the graph (1900-1930) is shown enlarged on the facing page.

Total vehicle-miles traveled increased each year from 2011 to 2019. The trend of using two-axle, four-tire trucks,
such as pickups, vans, and sport-utility vehicles, for personal travel is evident in these data; two-axle, four-tire
trucks account for 36% more travel in 2019 than in 1970, and cars account for 40% less travel between those two
time periods.

The number of trucks in the United States has grown significantly since 1970, some of it due to the use of light
trucks (pickups, vans, sport utility vehicles) as personal passenger vehicles. Those light trucks, as well as
medium and heavy trucks, are included in the data. In 1970 about 15% of trucks were age 15 or older; by 2013,
that increased to 20.8%.

30 years old for the mid-term evaluation of the Light Vehicle Greenhouse Gas Emissions Standards and Corporate
Average Fuel Economy Standards. The “Total” row represents the number of miles a car or light truck would
travel if it is in operation for 30 years. Typical lifetime miles from a 2006 study by the National Highway Traffic

Using current registration data and a scrappage model by Greenspan and Cohen [1996 paper:
www.federalreserve.gov/pubs/feds/1996/199640/199640pap.pdf], ORNL calculated heavy truck (trucks over
26,000 lb gross vehicle weight) scrappage rates. The expected median lifetime for a 1990 model year heavy truck
is 29 years. These data are fitted model values which assume constant economic conditions.

Definition of Light Truck
Often for regulatory purposes, agencies within the federal government have differing
definitions for the term “light truck.” Private data collectors, such as Ward’s Communications or
IHS Automotive/Polk, have their own definitions as well. The paragraphs below are intended as a
guide to the different definitions which are used in this document.
The data in Table 4.2 are from the Federal Highway Administration (FHWA). From 1970 to
2008 the FHWA defined light trucks as two-axle, four-tire trucks, including pickups, vans, SUVs,
and other two-axle, four-tire trucks under 10,000 lb gross vehicle weight rating (GVWR). In 2009,
the FHWA changed methodologies and no longer publishes vehicle miles, fuel use, and fuel
economy of light trucks separately from cars. They continue to publish vehicle registrations for
pickups, vans, SUVs and other two-axle, four tire trucks under 10,000 lb. The methodology used
by Oak Ridge National Laboratory (ORNL) to continue the data series on Table 4.2 after 2008 is
based on the FHWA data for all light vehicles, thus uses the same definition of light trucks. See
Section 7.2 in Appendix A for the methodology of light truck data on Table 4.2 after 2008. Data
on energy use in Tables 2.7 through 2.9 also use the FHWA definition of light truck.
Tables 3.6, 4.4, and 4.7 are light truck sales based on Ward’s Communications data. Ward’s
definition of light trucks includes pickups, vans, SUVs, and specialty purpose vehicles up to
14,000 lb GVWR. However, in most cases, data are available by individual GVWR and ORNL
summarized only light trucks that were 10,000 lb GVWR or less and did not include the heavier
trucks. Thus, the definition on these tables is nearly identical to the FHWA definition.
The Environmental Protection Agency (EPA) and the U. S. Department of Transportation,
National Highway Traffic Safety Administration (NHTSA), issued joint rulemaking to establish
Corporate Average Fuel Economy (CAFE) standards and greenhouse gas emissions standards
beginning with model year 2012. The rulemaking established new definitions of cars and light
trucks. Before the rule, CAFE standards applied to cars and light trucks (pickups, vans, SUVs, and
other trucks) less than 8,500 lb GVWR. After the rule, some two-wheel drive SUVs are considered
cars instead of light trucks, and personal passenger vehicles (vans and SUVs) up to 10,000 lb
GVWR are considered light trucks. Thus, data are now categorized as cars, car SUVs, truck SUVs,
pickups and vans. Table 4.10 gives a listing of which SUVs are considered car SUVs for model
year 2016. The EPA revised their data series back to 1975, so the definitions are consistent
historically. Data on tables 4.9 through 4.19 are based on EPA data and thus use this definition of
cars and light trucks. The CAFE data on Table 4.27 apply to cars only through 2011 and cars plus
car SUVs after that. The CAFE data on Table 4.28 are for trucks up to 8,500 lb GVWR through
2011 and after that are for truck SUVs and vans up to 10,000 lb GVWR, and pickup trucks up to
8,500 lb GVWR.
Because of these different definitions, caution is advised when comparing light truck data from
different sources.

The data in this table from 1985–on DO NOT include minivans, pickups, or sport utility vehicles. Much of the data
for 2009-on were estimated; the FHWA no longer publishes travel and fuel data for cars. A methodology change
for the number of cars registered affected the series in 2012.

These data are the combination of the car and two-axle, four-tire truck data from Tables 4.1 and 4.2 thus the data
may not match exactly with the FHWA VM-1 table’s light-duty vehicle data. The methodology change after 2008
affects these data as well.

Because data on class 2b trucks are scarce, the U.S. DOE funded a study to investigate available sources of data.
In the final report, four methodologies are described to estimate the sales of class 2b trucks. The 1999 data are
the latest available for fuel use and vehicle miles of travel of class 2b trucks.

Car sales in 2020 were at the lowest point in this series. Consumer preference towards sport utility vehicles is likely
the reason for the decline. In 1980, Chrysler/FCA, Ford and General Motors held 73.8% of the market; by 2020,
that dropped to 17%.

Light trucks, which include pick-ups, minivans, sport-utility vehicles, and other trucks less than 10,000 pounds
gross vehicle weight (GVW), have grown more popular and by 2020 accounted for 75.9% of all light vehicle sales.
Imports accounted for only 22.9% of 2020 light truck sales.

The relationship between gallons used over a given distance and miles per gallon (mpg) is not linear. Thus, an
increase in fuel economy by 5 mpg does not translate to a constant fuel savings amount. Replacing a low-mpg car
or truck with one that has just slightly better fuel economy will save more fuel than replacing a high-mpg car or
truck with a more efficient vehicle. For example, replacing a truck that gets 10 mpg for a new one that gets 15 mpg
will save 33 gallons of fuel for every 1,000 miles driven. In contrast, replacing a 30-mpg car with a new car that
gets 35 mpg will save 5 gallons of fuel for every 1,000 miles driven.

The fuel economy values that manufacturers must use to comply with the Corporate Average Fuel Economy (CAFE)
standards are not the same as fuel economy values on new vehicle window stickers. Nor are they the same as the
real-world estimates published in Tables 4.9, 4.11, and 4.12. The number of test cycles used and the weighting of
city and highway mileage differs with these three fuel economy metrics. The example of a 2021 Toyota Prius Eco
shows a combined fuel economy of 81 miles per gallon (mpg) for CAFE purposes, 56 mpg for the window sticker,
and 55 mpg as the best real-world estimate. The fuel economy difference is not constant among vehicle models.

The production-weighted fuel economy of cars increased dramatically from 1975 (13.5 mpg) to 1985 (23.0 mpg)
but rose only 0.5 mpg from 1985 to 2005. Since 2005, fuel economy rose 8.2 mpg—from 23.5 mpg in 2005 to 31.7
mpg in 2021. The fuel economy values have been adjusted to provide the best estimate of real-world performance.

A vehicle classification was created to match the Corporate Average Fuel Economy (CAFE) methodology. Under
CAFE, two-wheel and all-wheel drive sport utility vehicles that are under 6,000 lb gross vehicle weight and do not
have off road capabilities will be held to the same standards as cars. The Environmental Protection Agency has
labeled these vehicles as “car SUVs.”

Production of sport utility vehicles (SUVs) has grown substantially since 1975. The production-weighted fuel
economy of truck SUVs was 24.0 mpg in 2021. Estimates show 67.8% of all light trucks produced in 2021 were
truck SUVs.

The average fuel economy of cars more than doubled from 1975 to 2021 while the average fuel economy of light
trucks grew by 94% in that same time period. This was not steady annual growth, but growth in the 1970’s and
early 1980’s followed by a long period with little improvement. Growth resumed around 2008-2009.

Back in 1975 only 19.3% of new light vehicles produced were light trucks. Because of the boom in production of
minivans, sport utility vehicles, and pick-up trucks, that number rose to over 40% in 1998. Since 2018 more than
half of light vehicles produced were light trucks. The car SUV category was 11.7% of production in 2021 and the
truck SUVs were 41.4%.

The effects of the Japanese earthquake/tsunami in 2011 are apparent in the large decline in car production for that
year. Light trucks were gaining market share from the early 1980s until 2004, mainly due to increases in the market
share of sport utility vehicles (SUVs) and pickup trucks. Car SUVs are two-wheel drive SUVs that are counted as
cars in the Corporate Average Fuel Economy Standards for model years 2011-on. A listing of the makes/models of
car SUVs is in Table 4.10.

The number of transmission speeds in new light-duty vehicles has been growing over the last few decades. By 2021,
91% of cars and 96% of light trucks were at least six speeds. The share of light truck transmissions in the 9 & 10speed category grew to 35% in 2021. Continuously variable transmissions (CVTs) were 43% of car production and
18% of light truck production. A greater number of gears improves fuel economy and performance by more closely
matching the wheel speed to the optimum engine speed.

Note: Data are production-weighted averages for each model year. Data for model year 2021 are preliminary. CVT
data include both hybrid and non-hybrid. The "Other" category includes electric vehicles and plug-in hybrid-electric
vehicles. Data include light trucks less than 8,500 lb Beginning with 2011, SUVs and passenger vans up to 10,000 lb
were also included.

Increased performance typically comes as a trade-off with fuel economy. But light vehicle manufacturers have been
able to employ advanced technologies to improve both performance and fuel economy. Despite a 143% increase in
horsepower and 51% improvement in acceleration from model year 1980 to 2021, the fuel economy of vehicles
improved 32%. In the 1990s and early 2000s, fuel economy decreased while vehicle weight increased. Fuel
economy has improved nearly every year since 2004.

Manufacturers have introduced new technologies that have played a significant role in improving the fuel economy
of passenger cars. Turbocharging has enabled manufacturers to downsize engines without sacrificing performance
while gasoline direct injection has improved combustion efficiency in the engine. Cylinder deactivation is another
strategy for reducing engine displacement that shuts down cylinders under light load conditions. Stop-start reduces
unnecessary idling by automatically shutting down the engine when the vehicle is stopped and restarting the engine
only when needed. Continuously variable transmissions improve efficiency by maintaining optimum engine speed
as the vehicle speed varies. Penetration of direct injection has grown rapidly and was installed on 50.6% of all new
cars in model year (MY) 2021. Turbochargers were installed on 35.0% of new cars produced in MY 2021.

Manufacturers have introduced a number of engine and transmission technologies to improve the fuel efficiency
and performance of light trucks. Gasoline direct injection has seen rapid market penetration from about 1% of all
new light trucks produced in model year (MY) 2008 to nearly 60% by MY 2021. Cylinder deactivation,
turbocharging, and stop-start have all seen increased penetration with each of these technologies reaching more
than 20% of production for light trucks in MY 2021. The penetration of continuously variable transmissions
(CVT) is lower for light trucks than for cars because CVTs are not generally well suited to the high horsepower
and high torque requirements of pickup trucks and large SUVs that provide greater load hauling and towing
capability.

Note: The presented rates of increase in stringency for NHTSA CAFE standards are lower than the Environmental
Protection Agency (EPA) rates of increase in stringency for greenhouse gas (GHG) standards. One major difference
is that NHTSA’s standards, unlike EPA’s, do not reflect the inclusion of air conditioning system refrigerant and
leakage improvements, but EPA’s standards would allow consideration of such improvements which reduce GHGs
but generally do not affect fuel economy. The agencies expect, however, that a portion of these improvements will be
made through reductions in air conditioning leakage, which would not contribute to fuel economy.

The target levels for the fuel economy and carbon dioxide emission standards for vehicles manufactured in model
years 2012-on are assigned based on a vehicle’s “footprint.” Each footprint has a different target. The vehicle
footprint is calculated as:
footprint = track width × wheelbase,
where
track width = lateral distance between the centerlines of the base tires at ground, and
wheelbase = longitudinal distance between the front and rear wheel centerlines.

The Corporate Average Fuel Economy standards were first established by the U.S. Energy Policy and Conservation
Act of 1975 (PL94-163). These standards must be met at the manufacturer level. Legislation passed in December
2007 changed the CAFE standard methodology beginning in the 2011 model year (MY). Some two-wheel drive
sport utility vehicles are classified as cars under the final standards for MY 2011 on.

The Corporate Average Fuel Economy standards for light trucks are lower than the car standards. Light trucks
include pickups, minivans, sport utility vehicles and vans. Legislation passed in December 2007 changed the CAFE
standard methodology beginning in the 2011 model year (MY). Some two-wheel drive sport utility vehicles are
classified as cars under the final standards for MY 2011 on.

Manufacturers of cars and light trucks whose vehicles do not meet the CAFE standards are fined. Data from the
National Highway Traffic Safety Administration show the CAFE fine in the year in which the money was collected,
which may not be the same year in which it was assessed. A manufacturer can also use CAFE credits to offset fines.
Fines for recent model years have not been collected.

Consumers must pay the Gas Guzzler Tax when purchasing a car that has an Environmental Protection Agency
(EPA) fuel economy rating (combined city and highway) less than that stipulated in the table below. The Gas
Guzzler Tax doubled in 1991 after remaining constant from 1986 to 1990. The tax has not changed since 1991.
This tax does not apply to light trucks such as pickups, minivans, sport utility vehicles, and vans.

The IRS collected $42 million from those buying model year 2018 cars with combined city/highway fuel economy
less than 22.5 miles per gallon. This tax does not apply to light trucks such as pickups, minivans, sport utility
vehicles, and vans. It is worthy to note that total revenue from fines paid by consumers to purchase gas-guzzling
vehicles greatly exceeds the overall fines paid by manufacturers whose vehicles fail to meet CAFE standards (see
Table 4.279).

Autonomie is a system simulation tool for vehicle energy consumption and performance analysis. It is used to
evaluate the energy consumption and cost of multiple advanced powertrain technologies. Autonomie was used to
develop data on the relationship between steady-state vehicle speed and fuel economy.

The latest study of vehicle fuel economy by speed indicated higher fuel economy around 40 miles per hour, as did
the 1973 and 1984 studies. Engineers at Oak Ridge National Laboratory believe that the lowest speed in the
vehicle's highest gear is where the best fuel economy is typically obtained. That speed will be different for
individual vehicles.

This table shows the driving cycles for the new methodology that the Environmental Protection Agency (EPA) used
to determine fuel economy ratings for new vehicles beginning in model year 2008. In addition to the Urban Driving
Cycle and the Highway Driving cycle, the EPA will also use three additional tests to adjust fuel economy ratings
to account for higher speeds, air conditioner use, and colder temperatures. Though the EPA uses a complex
combination of these five cycles to determine the fuel economy that will be posted on a new vehicle window sticker,
the manufacturer’s Corporate Average Fuel Economy is still calculated using only the city and highway driving
cycles. To know more about new vehicle fuel economy ratings, visit www.fueleconomy.gov.

These driving cycles simulate the performance of an engine while driving in the city and on the highway. Once the
city cycle is completed, the engine is stopped, and then started again for the 8.5-minute hot start cycle. Three
additional cycles also influence new vehicle fuel economy ratings beginning with the 2008 model year.

cycle was originally developed as a supplement to the Federal Test Procedure. It is a short-duration cycle (600
seconds) which represents hard-acceleration driving.

Two other test cycles are sometimes used by researchers and engineers to test new vehicles (although these do not
affect the fuel economy ratings). The New York Test Cycle was developed in the 1970's in order to simulate driving
in downtown congested areas. The Representative Number Five Test Cycle was developed in the 1990's to better
represent actual on-road driving by combining modern city and freeway driving.

Testing cycles to determine vehicle fuel economy and emissions vary by country. The United States currently uses
five different drive cycles to determine vehicle fuel economy. In Europe, the NEDC cycle is being replaced by the
WLTC, but the NEDC continues to be used in China. The ARTEMIS cycles are not used in vehicle certification but
are used to represent real world driving in Europe.

Testing cycles to determine vehicle fuel economy and emissions vary by country and therefore it is difficult to make
a direct comparison. Simulation results show up to a 28% difference in the test cycles for each vehicle type. Note
that the differences in these cycle results also vary with each individual vehicle tested.

There are eight truck classes, categorized by the gross vehicle weight rating that the vehicle is assigned when it is
manufactured. The pictures below show examples of some of the different body types that would be included in
each class. Many of the body types can be in more than one category, depending on the vehicle’s attributes.
Examples of this include pickups, box trucks, buses, and truck tractors.

Class 3-8 single-unit trucks include trucks over 10,000 lb gross vehicle weight with the cab/engine and cargo space
together as one unit. Most of these trucks would be used for business or for individuals with heavy hauling or
towing needs. Very heavy single-units, such as concrete mixers and dump trucks, are also in this category. The
data series was changed by the FHWA back to 2007.

Class 7-8 combination trucks include all trucks designed to be used in combination with one or more trailers with
a gross vehicle weight rating over 26,000 lb. The average vehicle travel of these trucks (on a per truck basis) far
surpasses the travel of other trucks due to long-haul freight movement. The data series was changed by the FHWA
back to 2007.

Based on factory sales, the share of diesel medium/heavy trucks sold has declined from 1995 to 2019 for truck gross
vehicle weight rating (GVWR) classes 4 and 5. Class 6 diesel sales share increased in that period and class 8
continued to be nearly 100% diesel. In 2020, possibly due to pandemic disruption, there were very few Class 7
trucks produced (about 20% of the normal annual volume) and all of them were diesel. The result for all class 4
through 8 trucks combined was a decline from 87% diesel share in 1995 to 82% in 2020.

The Vehicle Inventory and Use Survey (VIUS) was discontinued, thus the 2002 VIUS data remain the latest
available.

Vehicle Inventory and Use Survey
The Vehicle Inventory and Use Survey (VIUS), which was formerly the Truck Inventory
and Use Survey (TIUS), provides data on the physical and operational characteristics of the
Nation's truck population. It is based on a probability sample of private and commercial trucks
registered (or licensed) in each state. In 1997, the survey was changed to the Vehicle Inventory
and Use Survey due to future possibilities of including additional vehicle types. The 2002 VIUS,
however, only includes trucks. Internet site: www.census.gov/econ/overview/se0501.html
Since 1987, the survey has included minivans, vans, station wagons on truck chassis, and
sport utility vehicles in addition to the bigger trucks. The 1977 and 1982 surveys did not include
those vehicle types. The estimated number of trucks that were within the scope of the 2002 VIUS
and registered in the United States as of July 1, 2002 was 85.2 million. These trucks were
estimated to have been driven a total of 1,115 billion miles during 2002, an increase of 6.8% from
1997. The average annual miles traveled per truck was estimated at 13,100 miles.
A new VIUS is planned for 2022 to collect data on 2021 truck activity and characteristics
similar to the previous surveys. Data collection begins in February 2022. Once the data are released
the tables in this chapter will be updated. Internet site for 2022 VIUS: www.bts.gov/vius.

As expected, most light trucks travel within 50 miles of their home base and refuel at public stations. About sixty
percent of heavy trucks travel over 50 miles from their home base and 36% of them refuel at central companyowned refueling stations.

The figure below shows the distribution of annual travel the two types of Class 7 and 8 vehicles–combination units
(separate tractor and trailer) and single units (tractor and trailer on a single chassis). This information is for all
trucks and trucks two years old or less. Combination trucks, dominated by box-type trailers, display the greatest
amount of annual travel of all heavy vehicle types, as is evidenced both by the range of annual use. Most of the
single-unit trucks in the survey travel 40,000 miles per year or less.

Figure 5.2. Distribution of Trucks over 26,000 lb by Vehicle-Miles Traveled, 2002

The latest Vehicle Inventory and Use Survey asked truck owners if the truck had certain features as permanent
equipment on the truck. Some of the features asked about were onboard computers, idle-reduction devices,
navigational systems, and Internet access. Of the 2.3 million heavy trucks (class 7 & 8) in the United States, nearly
10% were equipped with onboard computers that had communication capabilities and another 5% had onboard
computers without communication capabilities. Six percent of heavy trucks were equipped with idle-reducing
technology. Navigational systems and Internet access were available in less than one percent of heavy trucks.

Fuel Economy Study for Class 8 Trucks
As part of a study sponsored by the U.S. Department of Energy (DOE) Vehicle
Technologies Office (VTO), the Oak Ridge National Laboratory (ORNL) in conjunction with
several industry partners has collected data and information related to heavy-truck operation in
real-world highway environments. The primary objective of the project was to collect real-world
performance and spatial data for long-haul operations of Class 8 tractor-trailers from a fleet
engaged in normal freight operations. Six model-year 2005 Class 8 trucks from the selected fleet,
which operates within a large area of the country extending from the east coast to Mountain Time
Zone and from Canada to the US-Mexican border, were instrumented and 60 channels of data were
collected for over a year at a rate of 5 Hz (or 5 readings per second). Those channels included
information such as instantaneous fuel rate, engine speed, gear ratio, vehicle speed, and other
information read from the vehicle’s databus; weather information (wind speed, precipitation, air
temperature, etc.) gathered from an on-board weather station; spatial information (latitude,
longitude, altitude) acquired from a GPS (Global Positioning System) device; and instantaneous
tractor and trailer weight obtained from devices mounted on the six participating tractors and ten
trailers. Three of the six instrumented tractors and five of the ten instrumented trailers were
mounted with New Generation Single Wide-Based Tires and the others with regular dual tires.
Over the duration of this phase of the project (just over a year) the six tractors traveled nearly
700,000 miles.
The final report on this project is available on-line at:

The type of terrain a truck is traveling on can cause significant differences in fuel efficiency. This study (see page
5–15 for project description) shows fuel economy on severe upslopes is less than half that on flat terrain. On severe
downslopes, the fuel economy was two times higher than on flat terrain.

This table presents a distribution of distance traveled, fuel consumed, and fuel economy by speed and by type of
tires for the vehicles participating in the project (see page 5-15 for project description). The speed bins are divided
into 5-mile intervals, going from 0+ mph (i.e., speed > 0.00 mph) to 85 mph, while the four main columns of the
table are organized by the type of tires that were mounted on the tractor and trailers. The first row of the table
contains information about fuel consumed while the vehicle was idling (i.e., the vehicle was static with the engine
on) with the following rows presenting information about the distance traveled, fuel consumed, and fuel economy
for each one of the speed intervals. The next-to-the-last row shows the totals for both traveled distances and fuel
consumed as well as the overall fuel economy for each tire-combination category. The latter are then used to
compute the percentage difference in terms of fuel economy from dual tire tractors and trailers, which is the most
common tire setup for large trucks at the present time.

Note: These data were not adjusted to account for the effects of terrain. The increase in fuel economy for speeds
above 70 mph is likely due to the vehicle achieving high speeds while traveling down slope. Therefore, this increase
in fuel economy is not expected to be characteristic of all travel at these higher speeds.

The fuel economy information presented in Table 5.12 is on the upper limits of today’s large-truck fleets and is
mostly a result of driver training and the extensive vehicle maintenance (including constant tire pressure) to which
the fleet company participating in this project adheres. Nevertheless, the results of this extensive test indicate that
there are substantial gains in terms of fuel economy for large trucks when single (wide) tires are used in
combination with dual tires or alone (best case). Figure 5.4 shows the information from Table 5.12 in a graphical
form (bars) and also displays for each speed bin the percentage of the total distance that is traveled at that speed
(line). It is possible to observe that above 80% of the distance traveled by long-haul Class 8 trucks is done at
speeds above 55 mph. Therefore, any gains in fuel economies at these speeds derived from a given tire combination
would have a very large impact on the overall fuel economy of these types of trucks. Figure 5.4 shows that, except
for the D-S combination within the 65+ to 70 mph, the combinations with all single (wide) tires perform better and,
therefore, obtain the largest overall fuel economy.

The gross weight of a vehicle (GVW) is the weight of the empty vehicle plus the weight of the maximum payload
that the vehicle was designed to carry. In cars and small light trucks, the difference between the empty weight of
the vehicle and the GVW is not significantly different (1,000 to 1,500 lb). The largest trucks and tractor-trailers,
however, have a payload capacity share of 200%, which means they can carry 200% of their empty weight. The
medium-sized trucks (truck classes 3-6) have payload capacity shares between 50% and 100%.

According to weigh-in-motion data collected by fifteen states, the majority of 5-axle tractor-trailers on the road
weigh between 33,000 and 73,000 lb. Eleven percent of the tractor-trailers had weight recorded around 72,800 lb
and 10% around 68,300 lb. Another 10% of tractor-trailers were on the lighter end of the scale – around 37,500
lb. These data show that only a small percent of trucks on the road are near the maximum roadway gross vehicle
weight of 80,000 lb. Thus, most trucks are filling the trailer space to capacity (cubing-out) before they reach the
maximum weight limit (weighing-out).

Commodity Flow Survey
The Commodity Flow Survey (CFS) is designed to provide data on the flow of goods and
materials by mode of transport. The survey was first conducted in various years from 1963 to
1977, and was again conducted in 1993, 1997, 2002, 2007, 2012, and 2017 with improvements in
methodology, sample size, and scope. Final data for the 2017 survey was released in July 2020. It
is a shipper-based survey which covers business establishments from these industries:
•

Mining

•

Manufacturing

•

Wholesale trade

•

Select Retail and Services

Industries not covered by CFS include transportation, construction, most retail and services
industries, farms, fisheries, foreign establishments, and most government-owned establishments.
Before 1993 data were collected only on the principal mode of travel, but after that time all modes
of a shipment were captured in the data.
The CFS is a joint effort of the Bureau of Transportation Statistics and the U.S. Census Bureau.
Additional information on the survey can be found at:

Industries covered by the 2017 Commodity Flow Survey (CFS) shipped goods worth over $14 trillion. Compared
to the 1993 CFS, the value of shipments is up 1.2% per year. By value, multiple mode shipments increased 3.5%
per year from 1993 to 2017.

Freight Analysis Framework
The Freight Analysis Framework is a combination of sources drawn together to create a
comprehensive picture of freight movement in the U.S. in terms of tonnage, value, and ton-miles.
Data are available by origin, destination, commodity type, distance band, and mode. FAF origin
and destination data include state level or major metropolitan area. The sources of data for FAF
are the Commodity Flow Survey, international trade data from the Census Bureau, and other data
sources from agriculture, extraction, utility, construction, service, and other sectors.
Historically, FAF data are available for 1997, 2002, 2007, 2012, with estimated data for
2013-2018, and forecasted data from 2020-2045. A new version, FAF5, will be released in 2021
since the 2017 Commodity Flow Survey data were finalized in late 2020.
For additional information on FAF, see the website: faf.ornl.gov/fafweb.

For shipments of 100 miles or less, trucks moved 7.5 billion tons of freight in 2018. Trucks moved more tons than
other modes for all shipments less than 1,000 miles while rail moved more tons in shipments from 1,000-2,000
miles in length. More than 18 billion tons of freight were shipped in 2018.

Ranging from a speed limit of 55 miles per hour (mph) to 85 mph, the maximum speed limit for trucks varies from
state to state and sometimes from year to year. Currently, California has the most conservative maximum speed
limit for trucks – 55 mph. At the other end of the spectrum, Texas has some roads where the truck speed limit is 85
mph. Because of the varying limits, there is not one common highway speed at which trucks travel. Manufacturers
design the vehicle to perform well over the entire range of speeds.

Although all states allow the conventional combinations consisting of a 28-foot semi-trailer and a 28-foot trailer,
only 14 states and six state turnpike authorities allow longer combination vehicles (LCVs) on at least some parts
of their road networks. LCVs are tractors pulling a semi-trailer and trailer, with at least one of them – the semitrailer, the trailer, or both – longer than 28 feet. The routes that these LCVs can travel have not changed since
1991.

Alternative Fuels
The Energy Policy Act of 1992 defines alternative fuels and allows the U.S. Department of Energy
(DOE) to add to the list of alternative fuels if the fuel is substantially nonpetroleum, yields
substantial energy security benefits, and offers substantial environmental benefits. DOE currently
recognizes the following as alternative fuels:
•
•
•
•
•
•
•
•
•
•

methanol, ethanol, and other alcohols,
blends of 85% or more of alcohol with gasoline,
natural gas and liquid fuels domestically produced from natural gas,
liquefied petroleum gas (propane),
coal-derived liquid fuels,
hydrogen,
electricity,
biodiesel (B100),
fuels (other than alcohol) derived from biological materials,
P-series.

Alternative Fuels Data Center
DOE established the Alternative Fuels Data Center (AFDC) in 1991 to support its work aimed at
fulfilling the Alternative Motor Fuels Act directives. Since then, the AFDC has expanded its focus
to include all advanced transportation fuels, vehicles, and technologies. The AFDC is operated and
managed by the National Renewable Energy Laboratory (NREL) in Golden, Colorado.
The purposes of the AFDC are:
•

to gather and analyze information on the fuel consumption, emissions, operation, and
durability of alternative fuel vehicles, and

•

to provide unbiased, accurate information on alternative fuels and alternative fuel
vehicles to government agencies, private industry, research institutions, and other
interested organizations.

Much of the AFDC data can be obtained through their website: afdc.energy.gov. Several tables
and graphs in this chapter contain statistics which were generated by the AFDC. Below are some
links to specific areas of the AFDC website.

The Energy Information Administration (EIA) is no longer publishing estimates of the number of alternative
vehicles in use in the United States. EIA does publish the number of alternative fuel vehicles “made available”
each year, beginning in 2004. The alternative fuel vehicles “made available” are estimates from vehicle
manufacturer production and companies performing vehicle conversions. The data are more of a proxy for
alternative fuel vehicle sales than for vehicle population, but EIA cautions that the data are not actual sales data.

There were just over 3,000 propane stations in the United States in 1992 making up 89% of all alternative
refueling stations. Electric vehicle stations are now counted as all other fuels, with a station being one
geographic location where electricity is provided. Previously, the series changed to use the number of charging
plugs in 2011. There were more electric vehicle refueling stations in 2021 than any other alternative fuel.

Clean Cities is a locally-based government/industry partnership, coordinated by the U.S. Department of Energy to
expand the use of alternatives to gasoline and diesel fuel. By combining the decision-making with voluntary action
by partners, the "grass-roots" approach of Clean Cities departs from traditional "top-down" Federal programs.

The 2019 California Vehicle Survey

Data on vehicles operating in California are necessary for the California Energy
Commission to forecast future state transportation needs. The California Vehicle Survey was
begun two decades ago to meet those needs and has been conducted periodically since that time.
The survey uses a multi-method sampling approach with samples stratified by the six regions
defined across California (San Francisco, Sacramento, Central Valley, Los Angeles, San Diego,
and the Rest of California). The survey includes both residential and commercial light vehicle
owners, as well as an add-on survey for those who own or lease plug-in electric vehicles (PEV).
The PEV owner survey asks questions related to vehicle refueling, charging, use, and incentives.
Data from the California Vehicle Survey are shown in Tables 6.14-6.16 and Figures 6.2 and 6.3.

In the 2019 California Vehicle Survey, Level 1 and Level 2 charging are still the primary charging type to both
residential and commercial plug-in electric vehicle owners. The commercial plug-in electric vehicle owners were
more likely to report charging DC fast chargers.

California residential plug-in vehicle charging occurs more frequently in the overnight and evening hours. Some
utilities offer lower rates for off-peak electricity usage which usually begins in the evening. Plug-in vehicle
owners in those areas can schedule their charging to take advantage of lower rates.

Demand response vehicles (also called paratransit or dial-a-ride) are widely used by transit agencies. The vehicles
do not operate over a fixed route or on a fixed schedule. The vehicle may be dispatched to pick up several
passengers at different pick-up points before taking them to their respective destinations and may even be
interrupted en route to these destinations to pick up other passengers. Demand response service is provided
primarily by vans. In 2007, the data changed substantially due to improved estimation methodologies.
Unfortunately, those data are no longer comparable to the rest of the historical series.

Commuter rail, which is also known as regional rail or suburban rail, is long-haul rail passenger service operating
between metropolitan and suburban areas, whether within or across state lines. Commuter rail lines usually have
reduced fares for multiple rides and commutation tickets for regular, recurring riders.

The energy intensity of commuter rail systems, measured in Btu per passenger-mile, varies greatly. The average of
all commuter rail systems in 2019 was 1,589 Btu/passenger-mile. Most of these 27 systems used diesel power, but
five systems used both diesel and electricity, and another four systems used only electricity.

Shared Micromobility
Shared micromobility refers to small fleets of fully or partially human-powered vehicles
including bikes, e-bikes and e-scooters. Many cities in the United States now have some form of
shared micromobility available. Two different sources for shared micromobility data are
highlighted in Table 7.9 and Figures 7.4 through 7.9.
The National Association of City Transportation Officials (NACTO) began collecting data on
U.S. micromobility as early as 2010 and have published the data in annual reports entitled
Shared Micromobility in the U.S. The latest data available are for calendar year 2019. NACTO’s
trip count includes systems with over 150 bikes or scooters and only includes data reported by
105 large cities. It does not include private or closed campus systems like those operating on
university campuses. Data from several cities are combined to report more details on shared
micromobility, such as miles/minutes per trip, reasons for using shared bikes, and mode
replacement data.
In 2019 the North American Bikeshare and Scootershare Association (NABSA) began
publishing a report entitled Shared Micromobility State of the Industry Report. Two reports have
been published, one with 2019 data and another with 2020 data. The scope of this report is all of
North America (Canada, Mexico, United States). The 2020 report includes pandemic-related
data, in addition to industry, vehicle, and trip data. The primary data for this report were
collected through surveys distributed to all known shared micromobility operators and agencies
in North America.

TRANSPORTATION ENERGY DATA BOOK: EDITION 40—2022

In North American micromobility systems, large cities had a higher number of vehicles per system than small and
medium cities in 2020. Utilization of bikes was 158% higher in large cities than in small and medium cities in 2020.
Utilization of e-scooters was 76% higher in large cities.

The number of e-scooters that North Americans had access to decreased from 2019 to 2020, while the number of
e-bikes nearly doubled. There was only a slight decline in the number of available pedal bikes.

Micromobility sharing services (bikes and scooters) have expanded rapidly in cities across the United States. The
number of shared bike trips in the 100 largest U.S. cities has been estimated by the National Association of City
Transportation Officials (NACTO). The number of bike trips increased from 321 thousand in 2010 to 40 million
in 2019, with another 10 million electronic e-bike trips in addition. Shared scooter trips were added to the NACTO
study in 2018. There were 86 million scooter trips in 2019 representing 63% of the 136 million shared
micromobility trips taken.

Household vehicle ownership shows a dramatic increase from 1960 to 1990. In 1960, nearly 79% of households
owned less than two vehicles; by 1990, it declined to 45%. Census data prior to 1990 indicated that the majority
of households owned one vehicle; in 1990 that changed to two vehicles. Since 2000, less than 10% of households
had no vehicles. The share of households with three or more vehicles peaked in 2018. The American Community
Survey now collects these data on an annual basis, thus annual data are available after 2010.

2017 National Household Travel Survey Daily Trip Data
The U. S. Department of Transportation (DOT) collected data on daily trips in 1969, 1977, 1983, 1990
and 1995 via the Nationwide Personal Transportation Survey (NPTS). For 2001, the DOT combined the
collection of long trip and daily trip data into one survey – the 2001 National Household Travel Survey
(NHTS). The long trip data were not included in the 2009 or 2017 NHTS.
The NHTS is the nation’s inventory of daily travel. The survey includes demographic characteristics
of households, people, vehicles, and detailed information on daily travel for all purposes by all modes.
NHTS survey data are collected from a sample of U.S. households and expanded to provide national
estimates of trips and miles by travel mode, trip purpose, and a host of household attributes.
The NHTS was designed to continue the NPTS series, but as with all data surveys, caution should be
used when comparing statistics from one survey to another due to changes in terminology, survey
procedures, and target population. The NHTS surveys collected data on trips of children under 5 years of
age, while the previous NPTS did not. Improved methodologies first used in the collection of trip
information in the 1995 NPTS make it difficult to compare these data with past NPTS survey data. Thus,
the 1990 NPTS trip data have been adjusted to make it comparable with the later surveys.
In the 2017 survey, households were able to respond online as well as by phone. The online survey
included a mapping feature that allowed more accurate trip distances to be collected. These derived trip
distances appear to be about 10% shorter than self-reported trips.
A vehicle trip in the NHTS is defined as a one-way trip by a single privately-operated vehicle regardless
of the number of persons in the vehicle. A person trip is defined as a movement in the public space between
two identifiable points. Two household members traveling together in one car would be counted as two
person trips and one vehicle trip. Trips made in other highway vehicles, such as buses, streetcars, taxis
(including Uber/Lyft), and school buses are collected in the NHTS, but these are shown as person trips by
those modes because there is no way to trace movement of those vehicles throughout the day.

Note: Average vehicle trip length for 1990 and 1995 is calculated using only those records with trip mileage
information present. The 1969 survey does not include pickups and other light trucks as household vehicles. Data on
vehicles per household and licensed drivers per household will not match Table 9.2 and 8.3 because they come from
a different source.

Due to methodology improvements in collecting trip information, the 2001 and 1995 data should be compared only
to the 1990 adjusted data. The original 1990 data are comparable to all previous surveys; however, comparisons
should always be made with caution because of differing survey methodologies.

It is believed that the methodology changes in the 1995 NPTS did not affect journey-to-work trips; therefore,
no adjustment is necessary.

The number of drivers in a household makes a difference in vehicle miles of travel (vmt), as does the presence of
children in the household. Households with children have 64% more vmt than households without children in 2017.
Rural households have more vehicles, on average, than urban households.

In 2017, 24% of vehicle trips were traveling to and from work. Another 20% of trips were for shopping which is
down slightly from 2001. Shopping is done close to home, as the average trip length for shopping was only

Overall, household vehicle occupancy remained the same in 2017 as in 2009. Sport utility vehicle occupancy
declined from 1.90 to 1.83 from 2009 to 2017, while pickup truck occupancy stayed the same. Car occupancy was
nearly the same in those years as well.

The average vehicle occupancy, calculated as person-miles per vehicle-mile, is highest for social and recreational
purposes. The highest vehicle occupancy levels for all purposes were in 1977. The increase in number of vehicles
per household and the decrease in average household size could have contributed to the decline since then.

Historically, the data from the Nationwide Personal Transportation Survey (NPTS) are based on estimates reported
by survey respondents. For the 1995 NPTS and the 2001 National Household Travel Survey (NHTS), odometer
data were also collected. The 1995 data indicate that respondents overestimate the number of miles they drive in
a year, but the 2001 data do not show that same trend.

The ability to charge an electric vehicle (EV) at home depends upon access to electricity. A home with a garage or
carport is more likely to have electricity access close to the vehicle, thus making it more convenient to refuel. Nearly
three-fourths of newly constructed homes and 82% of single-unit dwellings had a garage or carport in 2019.

everyday travel. The everyday travel data is a continuation of the Nationwide Personal Transportation
Survey (NPTS), while the long-distance travel data is a continuation of the American Travel Survey (ATS)
which was collected in 1977 and 1985.

The survey collected trip-related data such as mode of

transportation, duration, distance and purpose of trip. It also gathered demographic, geographic, and
economic data for analysis purposes.
A long-distance trip is defined as a trip of 50 miles or more, one-way. Long-trip data from the 2001
NHTS were released in the summer of 2004. For additional information about the 2001 NHTS data, go to
the following website: nhts.ornl.gov.

These data include ALL international and domestic certificated route air carrier statistics; therefore, the data are
different than those in Chapter 2. The effects of the pandemic are evident in the 2020 data. Revenue passengermiles declined by 64% from 2019 to 2020.

In the early seventies, domestic waterborne commerce accounted for over 60% of total tonnage, but by 1994 foreign
tonnage grew to more than half of all waterborne tonnage. Total foreign and domestic tons shipped reached a peak
of 2.59 billion tons in 2006 and in 2019 were 2.36 billion tons.

The U.S. Army Corps of Engineers Navigation Data Center collects a wealth of waterborne commerce data. Energy
use data, however, have never been collected as part of this effort. The average length of haul in domestic
waterborne commerce was 560 miles in 2019.

The Interstate Commerce Commission designates Class I railroads on the basis of annual gross revenues. In 2019,
seven railroads were given this designation. The number of railroads designated as Class I has changed
considerably in the last 30 years; in 1976 there were 52 railroads given Class I designation.

Revenue ton-miles for Class I freight railroads was about 1.6 trillion in 2019. Though there are many regional and
local freight railroads, the Class I freight railroads accounted for 94% of the railroad industry’s freight revenue
in 2019 and 68% of the industry’s mileage operated. The energy intensity of Class I railroads hit an all-time low
of 289 Btu/ton-mile in 2010 and continued to be below 300 Btu/ton-mile in 2019.

According to the 2017 Commodity Flow Survey, 18% of all freight ton-miles are rail intermodal shipments
(truck/rail or rail/water). See Table 5.17 for details. Containerization has increased in the last two decades,
evidenced by the 449% increase in the number of containers from 1988 to 2019. The number of trailers moved by
rail fell to an all-time low in 2019.

Only end-use energy was counted for electricity. Previous editions included primary energy use for electricity
which included generation and distribution losses. Energy use for 1994 on is not directly comparable to earlier years.
Some commuter rail energy use may have been inadvertently included in earlier years.

Adjusting Dollar Amounts for Inflation

A dollar spent in 1970 does not have the purchasing power of a dollar spent in 2019 due
to the inflation of prices for all goods and services. Thus, prices in a historical series must be
adjusted in order to provide proper comparison. The term “current dollars” is used in this report
for dollar amounts that were current as of the year listed – this can also be referred to as
“nominal dollars.” The term “constant 2019 dollars” is used in this report for dollar amounts that
have been adjusted to a constant purchasing power (2019, in this example) and thus the data are
comparable historically – this can also be referred to as “real dollars.”
Appendix B, Table B.17 contains the Consumer Price Inflation Index and Table B.18
contains the Gross National Product Implicit Price Deflator since 1970. Tables in the report with
constant dollars have a footnote indicating which of these inflation adjustment indices were used.

The Transportation Services Index (TSI) was created by the U.S. Department of Transportation Bureau of
Transportation Statistics (BTS). It is an index that measures the movement of freight and passengers.
The Freight TSI consists of:
•
•
•
•
•

for-hire trucking (parcel services are not included);
freight railroad services (including rail-based intermodal shipments such as containers on flat cars);
inland waterway traffic;
pipeline movements (including principally petroleum and petroleum products and natural gas); and
air freight.

The index does not include international or coastal steamship movements, private trucking, courier services, or the
United States Postal Services.
The Passenger TSI consists of:
• local mass transit;
• intercity passenger rail; and
• passenger air transportation.
The index does not include intercity bus, sightseeing services, taxi service, private car usage, or bicycling and other
nonmotorized means of transportation.
The sharp travel declines in March and April 2020 were due to the COVID-19 pandemic.

The average amount of money that a household spends in a year has grown about 11% between 1985 and 2019 in
constant dollar terms. Expenditures on transportation were 19.4% of the total in 1985 but were only 17.0% in
2019. Vehicle purchases made up about 41% of transportation expenditures in 2019, while gas and oil were 19%.

The cost of crude oil influences the price of gasoline, but it is not the only factor which determines the price at the
pump. Refining cost, transportation cost, marketing cost, and taxes also play a part of the cost of a gallon of
gasoline. The average price of a barrel of crude oil declined to 39.8 dollars per barrel in 2020 from a high of
117.2 in 2011 (constant 2020 dollars).

The price of a gallon of gasoline changes depending on different price components, including taxes, distribution
and marketing, refining, and crude oil. The largest component of gasoline price is crude oil. The cost of refining
and the cost of crude oil are the most variable over the series.

The average price of diesel fuel has been consistently higher than regular gasoline (in constant dollars) since 2005.
Premium gasoline in 2020 averaged 62 cents higher than regular gasoline. Prices for diesel and gasoline declined
substantially in 2016 but rose again in 2017 and 2018 before declining again in 2019 and 2020.

Major oil price shocks have disrupted world energy markets five times in the past 30 years (1973-74, 1979-80,
1990-91, 1999-2000, 2008). Most of the oil price shocks were followed by an economic recession in the
United States.

The United States has long recognized the problem of oil dependence and the economic problems that arise from
it. Greene, Lee and Hopson define oil dependence as a combination of four factors: (1) a noncompetitive world oil
market strongly influenced by the Organization of the Petroleum Exporting Countries (OPEC) cartel, (2) high
levels of U.S. imports, (3) the importance of oil to the U.S. economy, and (4) the lack of economical and readily
available substitutes for oil. The most recent study shows that the U.S. economy suffered the greatest losses in 2008
when wealth transfer and gross domestic product (GDP) losses (combined) amounted to nearly half a trillion
dollars. However, when comparing oil dependence to the size of the economy, the year 1980 is the highest. Low oil
prices in 2009-2010 and 2013-2014 caused total dependence cost to drop; in 2018, the total cost was about
$100 billion (in 2018 dollars).

Figure 11.7. Costs of Oil Dependence to the U.S. Economy, 1970–2018

Notes:
Wealth Transfer is the product of total U.S. oil imports and the difference between the actual market price of oil
(influenced by market power) and what the price would have been in a competitive market.
Dislocation Losses are temporary reductions in GDP as a result of oil price shocks.
Loss of Potential Gross Domestic Product (GDP) results because a basic resource used by the economy to produce
output has become more expensive. As a consequence, with the same endowment of labor, capital, and other
resources, our economy cannot produce quite as much as it could have at a lower oil price.

The fuel prices shown here are refiner sales prices of transportation fuels to end users, excluding tax. Sales to end
users are those made directly to the ultimate consumer, including bulk consumers. Bulk sales to utility, industrial,
and commercial accounts previously included in the wholesale category are now counted as sales to end users.
Both propane and diesel prices fell drastically in 2015. Although both fuels experienced price increases from 2016
to 2018, they declined again in 2019 and 2020.

The federal government taxes highway motor fuel and uses the money to pay for roadway upkeep and improvement,
as well as other related expenditures. Compressed natural gas (CNG) and liquefied petroleum gas (LPG) taxes are
calculated per energy equivalent of a gallon of gasoline, while liquified natural gas tax is calculated per energy
equivalent of diesel.

In addition to the 18.4 cents per gallon federal gasoline tax, the states also tax gasoline at varying rates. Some
states have sales and/or use taxes added to gasoline excise taxes while others have inspection fees, environmental
fees, leaking underground storage tank taxes, etc. The Energy Information Administration has compiled gasoline
excise taxes, along with other state taxes and fees, to arrive at an estimate of the amount of state taxes consumers
are paying per gallon.

Global Warming Potentials (GWP) were developed to allow comparison of the ability of each greenhouse gas to
trap heat in the atmosphere relative to carbon dioxide. Extensive research has been performed and it has been
discovered that the effects of various gases on global warming are too complex to be precisely summarized by a
single number. Further understanding of the subject also causes frequent changes to estimates. Despite that, the
scientific community has developed approximations, the latest of which are shown below. Most analysts use the
100-year time horizon.

This report has typically displayed carbon and carbon dioxide data from the Environmental Protection Agency
(EPA). However, the Energy Information Administration’s (EIA’s) Monthly Energy Review also includes carbon
dioxide emission data. The differences in the two-data series have been about 5-7%, but as high as 8.5% in 1991.
Reasons for the differences include the treatment of international bunker fuel, nonfuel use of fossil fuels, and the
agencies’ use of different fuel consumption control totals.

The Greenhouse Gases, Regulated Emissions, and Energy Use
in Technologies (GREET) Model

greet.es.anl.gov
Sponsored by the U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy
(EERE), Argonne has developed a full life-cycle model called GREET® (Greenhouse gases, Regulated
Emissions, and Energy use in Technologies). It allows researchers and analysts to evaluate energy and
environmental impacts of various vehicle and fuel combinations on a life-cycle basis. The first version of
GREET was released in 1996. Since then, Argonne has continued to update and expand the model. The
most recent GREET versions are GREET 1 2021 version for fuel-cycle analysis and GREET 2 2021 version
for vehicle-cycle analysis.
Figure 12.2. GREET Model

For a given vehicle and fuel system, GREET separately calculates the following:
•

Consumption of total resources (energy in non-renewable and renewable sources), fossil
fuels (petroleum, natural gas, and coal together), petroleum, coal, natural gas, and water.

•

Emissions of CO2-equivalent greenhouse gases - primarily carbon dioxide (CO2), methane
(CH4), and nitrous oxide (N2O).

TRANSPORTATION ENERGY DATA BOOK: EDITION 40—2022

12–12

•

Emissions of seven criteria pollutants: volatile organic compounds (VOCs), carbon
monoxide (CO), nitrogen oxide (NOx), particulate matter with size smaller than 10 micron
(PM10), particulate matter with size smaller than 2.5 micron (PM2.5), black carbon (BC) and
sulfur oxides (SOx).

GREET includes more than 100 fuel production pathways and more than 80 vehicle/fuel systems.
These vehicle/fuel systems cover current and advanced vehicle technologies such as conventional sparkignition engine vehicles, compression-ignition engine vehicles, hybrid electric vehicles, plug-in hybrid
electric vehicles, battery-powered electric vehicles and fuel-cell electric vehicles. GREET also evaluates
transportation modes other than light-duty vehicles, such as heavy-duty vehicles, aviation, rail and marine.
Figure 12.3. GREET Model Feedstocks and Fuels

To address technology improvements over time, GREET 2021 simulates current and future vehicle/fuel
systems up to year 2050.
For additional information about the GREET model and associated documentation, please visit the
GREET website www.greet.es.anl.gov, or contact greet@anl.gov.

Results from the GREET 1 2021 model on emissions of carbon dioxide equivalents per mile are shown
for various fuels and vehicle technologies. A full description of the model is on the preceding pages.

Greenhouse gas emissions associated with vehicle manufacturing (current technology) were estimated
using the GREET model. Emissions from manufacturing the vehicle body are about two tonnes of carbon
dioxide equivalent for each of the vehicle types. Emissions from the manufacture of the hydrogen onboard storage cause the total emissions associated with the manufacture of a hydrogen fuel cell vehicle
to be higher than the other vehicle types. Emissions from the manufacture of batteries cause BEV300
vehicles to have the highest total emissions.

Carbon Footprint

The carbon footprint measures a vehicle’s impact on climate change in tons of carbon dioxide (CO2)
emitted annually. The following three tables show the carbon footprint for various vehicle classes. The
sales-weighted average fuel economy rating for each vehicle class, based on 45% highway and 55% city
driving, is used to determine the average annual carbon footprint for vehicles in the class. An estimate of
15,000 annual miles is used for each vehicle class and for each year in the series.

LHV = Lower (or net) Heating Value in million Btu per gallon

Note: The Environmental Protection Agency publishes tailpipe emissions in terms of grams of CO2 per

Though gasoline-powered light vehicles continue to be responsible for the majority of carbon monoxide emissions
from highway vehicles, the total pollution from light vehicles in 2005 is less than a fifth of what it was in 1970.
This is despite the fact that there were many more light vehicles on the road in 2005. Between 2005 and 2011 the
Environmental Protection Agency updated their source from the MOBILE 6.2 emissions model to the MOVES
emission model. MOVES results typically show higher emissions, especially for heavy trucks. The 2017 data were
released in 2019-2020.

The transportation sector accounted for less than 1.5% of the nation’s sulfur dioxide (SO2) emissions in 2020, with
off-highway vehicles responsible for most of the emissions. Stationary fuel combustion (e.g. electricity generation)
was responsible for about 63% of all SO2 emissions in 2020.

EMISSION STANDARDS
The U.S. Environmental Protection Agency (EPA) regulates emissions from mobile sources
including vehicles, engines, and motorized equipment that produce exhaust and evaporative emissions.
Mobile sources contribute to four main air pollutants: carbon monoxide, hydrocarbons, nitrogen oxides,
and particulate matter. The EPA not only sets standards for the vehicles, engines, and equipment, but also
the fuels that they use. Tables 13.13 through Table 13.30 contain summaries of the current standards.

The Environmental Protection Agency issued final Tier 3 emission standards in 2014. The combined emissions of
non-methane organic gases (NMOG) and nitrogen oxides (NOx) that new gasoline engines are allowed to produce
from model years 2017 to 2025 are regulated in these new standards. These standards apply to a corporate
average, meaning that some vehicles produced in those model years will emit more than the standard, while others
will emit less, so long as the average for each Original Equipment Manufacturer (OEM) product offerings meets
the standard.

The modified averaging, banking, and trading program for 1998 and later model year engines applies only to
diesel cycle engines. Credits generated under the modified program may be used only in 2004 and later model years.
j
For heavy-duty diesel engines, there are three options to the measurement procedures currently in place for
alternative fueled engines: (1) use a THC measurement in place of an non-methane hydrocarbon (NMHC)
measurement; (2) use a measurement procedure specified by the manufacturer with prior approval of the
Administrator; or (3) subtract two percent from the measured THC value to obtain an NMHC value. The methodology
must be specified at time of certification and will remain the same for the engine family throughout the engines' useful
life. For natural gas vehicles, EPA allows the option of measuring NMHC through direct quantification of individual
species by gas chromatography.
k
Starting in 2006, refiners must begin producing highway diesel fuel that meets a maximum sulfur standard of
15 parts per million (ppm).
l
Subject to a Supplemental Emission Test (1.0 x Federal Test Procedure [FTP] standard (or Family Emission
Limit [FEL]) for nitrogen oxides [NOx], NMHC, and particulate matter [PM]) and a NTE test (1.5 x FTP standard [or
FEL] for NOx, NMHC, and PM).
m
EPA adopted the lab-testing and field-testing specifications in 40 CFR Part 1065 for heavy-duty highway
engines, including both diesel and Otto-cycle engines. These procedures replace those previously published in 40
Code of Federal Regulations (CFR) Part 86, Subpart N. Any new testing for 2010 and later model years must be done
using the 40 CFR Part 1065 procedures.
n
Two-phase in-use NTE testing program for heavy-duty diesel vehicles. The program begins with the 2007
model year for gaseous pollutants and 2008 for PM. The requirements apply to diesel engines certified for use in
heavy-duty vehicles (including buses) with GVWRs greater than 8,500 pounds. However, the requirements do not
apply to any heavy-duty diesel vehicle that was certified using a chassis dynamometer, including medium-duty
passenger vehicles with GVWRs of between 8,500 and 10,000 pounds.
o
NOx and NMHC standards will be phased in together between 2007 and 2010. The phase-in will be on a
percent-of-sales basis: 50 percent from 2007 to 2009 and 100 percent in 2010.
p
Note that for an individual engine, if the useful life hours interval is reached before the engine reaches 10
years or 100,000 miles, the useful life shall become 10 years or 100,000 miles, whichever occurs first, as required
under Clean Air Act section 202(d).

Heavy-Duty Highway Spark-Ignition Engines – Exhaust Emission Standards

For natural gas fueled engines the standard is 1.7 g/bhp-hr NMHC.
The NOx standard is 5.0 for all natural gas-fueled engines.
j
This standard applies to the following engines utilizing aftertreatment technology (except for methanol) for
the following model years: gasoline/1990+; natural gas and LPG/1991+; methanol/1990+. Starting in 2005, engines
certified to on-board diagnostics requirements are not required to meet the idle carbon monoxide (CO) standard.
k
Useful life is expressed in years or miles, whichever comes first. Useful life for the 1998 and later NOx
standard and for all 2004 standards is 10 years or 110,000 miles, whichever comes first.
l
Manufacturers can choose this standard or one of the following options: (1) a standard of 1.5 g/bhp-hr
NMHC+NOX that applies to the 2004 through 2007 model years, with complete heavy-duty vehicle standards taking
effect in 2005; or (2) a standard of 1.5 g/bhp-hr NMHC + NOX that would apply to the 2003 through 2007 heavyduty engines and optionally to 2003 through 2006 complete heavy-duty vehicles.
m
Standard is expressed as non-methane organic gas, but compliance can optionally be shown using
measurement of NMHC or total hydrocarbon (THC).
n
Complete heavy-duty vehicles have the primary load-carrying container or device attached. Incomplete heavyduty vehicles are certified to heavy-duty engine standards. Standards for complete heavy-duty vehicles are expressed
in grams per mile (g/mi). Starting in 2005 (or 2003 or 2004 depending on the selected phase in option; see footnote
l), complete heavy-duty vehicles under 14,000 lbs gross vehicle weight are tested on chassis-based rather than enginebased procedures and must meet these complete heavy-duty vehicle standards.
o
Although expressed as NMHC, compliance can optionally be shown using measurement of NMOG or THC.
p
At least 50 percent of a manufacturer's sales must meet these standards in 2008, with 100 percent required in
2009.
q
Gross vehicle weight ranges are more accurately specified as follows: 8,500 ≤ GVW ≤ 10,000 and 10,000 <
GVW < 14,000.

40 CFR 1048.110 = Engine diagnostic requirements (Additional resources: www.epa.gov/emission-standardsreference-guide/nonroad-engines-and-vehicles-emission-standards)

The numerical emission standards for hydrocarbons (HC) must be met based on the following types of
hydrocarbon emissions for engines powered by the following fuels: (1) non-methane hydrocarbons (NMHC) for
natural gas; (2) total hydrocarbon equivalent (THCE) for alcohol; and (3) total hydrocarbons (THC) for other fuels.
b
Voluntary Blue Sky standards for large spark-ignition (SI) engines are available. Engines with displacement
at or below 1,000 cubic centimeters (cc) and maximum power at or below 30 kilowatts (kW) may be certified under
the program for small SI engines.
c
Emission standards are based on testing over a steady-state duty-cycle.
d
The Tier 1 HC plus nitrogen oxides (NOx) emission standard for in-use testing is 5.4 grams per kW-hour
(g/kW-hr).
e
Useful life is expressed in years and hours, whichever comes first. These are the minimum useful life
requirements. For severe-duty engines, the minimum useful life is seven years or 1,500 hours of operation, whichever
comes first. A longer useful life in hours is required if: (a) the engine is designed to operate longer than the minimum
useful life based on the recommended rebuild interval; or (b) the basic mechanical warranty is longer than the
minimum useful life.
f
Optional engine certification is allowed according to the following formula: (HC+NOx) × CO0.784 ≤ 8.57. The
HC+NOx and carbon monoxide (CO) emission levels selected to satisfy this formula, rounded to the nearest 0.1 g/kWhr, become the emission standards that apply for those engines. One may not select an HC+NOx emission standard
higher than 2.7 g/kW-hr or a CO emission standard higher than 20.6 g/kW-hr.

a
These standards apply to locomotives that are propelled by engines with total rated horsepower (hp) of 750
kilowatts (kW) (1006 hp) or more, unless the owner chooses to have the equipment certified to meet the requirements
of locomotives. This does not include vehicles propelled by engines with total rated horsepower of less than 750 kW
(1006 hp); see the requirements in 40 Code of Federal Regulations (CFR) Parts 86, 89 and 1039. The test procedures
specify chassis-based testing of locomotives. These test procedures include certification testing, production line
testing, and in-use testing using the Federal Test Procedure (FTP) when the locomotive has reached between 50-70
percent of its useful life.
b
Line-haul locomotives are powered by an engine with a maximum rated power (or a combination of engines
having a total rated power) greater than 2300 hp. Switch locomotives are powered by an engine with a maximum rated
power (or a combination of engines having a total rated power) of 2300 hp or less.
c
The Tier 0 standards apply to locomotives manufactured after 1972 when they are manufactured or
remanufactured. Note that interim standards may apply for Tier 0 or Tier 1 locomotives remanufactured in 2008 or
2009, or for Tier 2 locomotives manufactured or remanufactured in 2008-2012.
d Line-haul locomotives subject to the Tier 0 through Tier 2 emission standards must also meet switch standards
of the same tier.
e
The Tier 0 standards apply for 1993-2001 locomotives not originally manufactured with a separate loop intake
air cooling system.
f
Tier 3 line-haul locomotives must also meet Tier 2 switch standards.
g
Manufacturers using credits may elect to meet a combined nitrogen oxides (NOx) plus hydrocarbon (HC)
standard of 1.4 grams per brakehorsepower-hour (g/bhp-hr) instead of the otherwise applicable Tier 4 NOx and HC
standards.
h
Tier 1 and Tier 2 switch locomotives must also meet line-haul standards of the same tier.
i
The numerical emission standards for HC must be met based on the following types of hydrocarbon emissions
for locomotives powered by the following fuels: (1) alcohol: total hydrocarbon equivalent (THCE) emissions for Tier
3 and earlier locomotives, and non-methane hydrocarbon equivalent (NMHCE) for Tier 4; (2) natural gas and liquefied
petroleum gas: non-methane hydrocarbon (NMHC) emissions; and (3) diesel: total hydrocarbon (THC) emissions for
Tier 3 and earlier locomotives, and NMHC for Tier 4.

Table 13.25 (continued)
Locomotives – Exhaust Emission Standards

Manufacturers may elect to meet a combined NOx+HC standard of 1.4 g/bhp-hr instead of the otherwise
applicable Tier 4 NOx and HC standards.
k
The line-haul particulate matter (PM) standard for newly remanufactured Tier 2 locomotives is 0.20 g/bhp-hr
until January 1, 2013, except as specified in 40 CFR Part 1033.150(a).
l
The switch PM standard for new Tier 2 locomotives is 0.24 g/bhp-hr until January 1, 2013, except as specified
in 40 CFR Part 1033.150(a).
m
The smoke opacity standards apply only for locomotives certified to one or more PM standards or Family
Emission Limits (FEL) greater than 0.05 g/bhp-hr. Percentages apply to smoke opacity at steady state/30-second
peak/3-second peak, as measured continuously during testing.
n
Useful life and warranty period are expressed in megawatt-hours (MW-hr), years, or miles, whichever comes
first. Manufacturers are required to certify to longer useful lives if their locomotives are designed to last longer
between overhauls than the minimum useful life value.
o
For locomotives originally manufactured before January 1, 2000, and not equipped with MW-hr meters.

and Category 2 includes engines from 7 to 30 L/cylinder. The definition of Category 3 marine engines remains the
same.
b
Tiers 1 and 2 for marine engines less than 37 kW are subject to the same emission standards as for land-based
engines. See Table 1 in 40 Code of Federal Regulations (CFR) Part 89.112 and 40 CFR Part 89.104.
c
For Tiers 1 and 2, this refers to the rated power; for Tiers 3 and 4, this refers to the maximum engine power.
d
Total hydrocarbon (THC) plus nitrogen oxides (NOx) for Tier 2 standards.
e
Useful life is expressed in hours or years, whichever comes first. For Tiers 3 and 4, a longer useful life in
hours for an engine family must be specified if either:1) the engine is designed, advertised, or marketed to operate
longer than the minimum useful life; or 2) the basic mechanical warranty is longer than the minimum useful life.
f
Warranty period is expressed in years and hours, whichever comes first.
g
For Tiers 3 and 4, there are no evaporative emission standards for diesel-fueled engines, or engines using
other nonvolatile or nonliquid fuels (e.g., natural gas). If an engine uses a volatile liquid fuel, such as methanol, the
engine's fuel system and the vessel in which the engine is installed must meet the evaporative emission requirements
of 40 Code of Federal Regulations (CFR) Part 1045 that apply with respect to spark-ignition engines. Manufacturers
subject to evaporative emission standards must meet the requirements of 40 CFR 1045.112 as described in 40 CFR
1060.1(a)(2).
h
Indicates the model years for which the specified standards start.
i
N is the maximum test speed of the engine in revolutions per minute (rpm).
j
Manufacturers of Tier 3 engines greater than or equal to 19 kW and less than 75 kW with displacement below
0.9 L/cylinder may alternatively certify some or all of their engine families to a particulate matter (PM) emission
standard of 0.20 grams per kilowatt-hour (g/kW-hr) and a NOx+HC emission standard fo 5.8 g/kW-hr for 2014 and
later model years.
k
The applicable Tier 2 NOx+HC standards continue to apply instead of the Tier 3 values for engines at or
above 2000 kW.
l
These Tier 3 standards apply to Category 1 engines below 3700 kW except for recreational marine engines at
or above 3700 kW (with any displacement), which must meet the Tier 3 standards specified for recreational marine
engines with a displacement of 3.5 to 7.0 L/cylinder.
m
The following provisions are optional: 1) Manufacturers may use NOx credits to certify Tier 4 engines to a
NOX+HC emission standard of 1.9 g/kW-hr instead of the NOX and HC standards. See 40 CFR 1042.101(a)(8)(i) for
more details. 2) For engines below 1000 kW, manufacturers may delay complying with the Tier 4 standards until
October 1, 2017. 3) For engines at or above 3700 kW, manufacturers may delay complying with the Tier 4 standards
until December 31, 2016.
n
The Tier 4 standard is for HC (not HC+NOx) in g/kW-hr.
o
These Tier 3 standards apply to Category 2 engines below 3700 kW; no Tier 3 standards apply for Category
2 engines at or above 3700 kW, although there are Tier 4 standards that apply.

Fuel use in gallons (1970-2008) – DOT, FHWA, Highway Statistics 2008, Table VM-1 and
annual editions back to 1996; DOT, FHWA, Highway Statistics Summary to 1995.
Fuel use in gallons (2009–2019) – See Section 7. Appendix A Car and Light Truck Shares.
Fuel type distribution for gallons – Fuel use was distributed among fuel types using the
percentages shown in Table A.1. The FHWA discontinued gasohol data in 2005. Therefore, data
from EIA, Alternatives to Traditional Transportation Fuels, 2006-2011, Table C1 were used
through 2013. From 2014-on, author estimates were used, with knowledge of how the
Renewable Fuels Standard affects the gasoline/gasohol mix.
Electricity use (2010-2019) – Estimates derived using cumulative electric vehicle (EV) and
plug-in hybrid vehicle (PHEV) sales as a proxy for vehicle population; sales-weighted vehicle
efficiencies from the U.S. Department of Energy and U.S. Environmental Protection Agency’s
vehicle database on www.fueleconomy.gov; and annual miles traveled from varying PHEV
utility factors and EV usage assumptions. Methodology documented in an Argonne National
Laboratory report, Assessment of Light-Duty Plug-in Electric Vehicles in the United States, 2010

Fuel use in gallons (1970-2007) – DOT, FHWA, Highway Statistics 2008, Table VM-1 and
annual editions back to 1996 and DOT, FHWA, Highway Statistics Summary to 1995.
Fuel use in gallons (2008–2019) – See Section 7. Appendix A Car and Light Truck Shares.
Fuel type distribution for gallons – Fuel use was distributed among fuel types using the
percentages shown in Table A.1. The FHWA discontinued gasohol data in 2005. Therefore, data
from EIA, Alternatives to Traditional Transportation Fuels, 2006-2011, Table C1 were used
through 2013. From 2014-on, author estimates were used, with knowledge of how the
Renewable Fuels Standard affects the gasoline/gasohol mix.
Electricity use (2010-2019) – Estimates derived using cumulative electric vehicle (EV) and
plug-in hybrid vehicle (PHEV) sales as a proxy for vehicle population; sales-weighted vehicle
efficiencies from the U.S. Department of Energy and U.S. Environmental Protection Agency’s
vehicle database on www.fueleconomy.gov; and annual miles traveled from varying PHEV
utility factors and EV usage assumptions. Methodology documented in an Argonne National
Laboratory report, Assessment of Light-Duty Plug-in Electric Vehicles in the United States, 2010
– 2020, June 2021, doi.org/10.2172/1785708. For tables in the main body of the TEDB,
electricity was converted from kWh to Btu using 3,412 Btu/kWh.

2.2 OFF-HIGHWAY ENERGY USE
U.S. Environmental Protection Agency, MOVES2014b model, results generated September
2020. Data by fuel type were produced for agricultural equipment, airport equipment,
construction and mining equipment, industrial equipment, lawn and garden equipment, logging
equipment, railroad maintenance equipment, and recreational equipment. Some nontransportation-related equipment, such as generators, chain saws, compressors, and pumps, were
excluded from the data. Model output was converted from grams to gallons using EPA’s
methodology documented in the technical report Greenhouse Gas and Energy Consumption
Rates for On-road Vehicles: Updates for MOVES2014, www.epa.gov/moves/can-moves-reportoutput-terms-fuel-consumption.

for international include fuel purchased abroad, for the tables in TEDB Chapter 2, the
international total was divided in half to estimate domestic fuel use for international flights.

2.3.3 Pipeline
The sum of natural gas, crude petroleum and petroleum product, and coal slurry and water.
Natural Gas
The amount of natural gas used to transport natural gas was defined as "pipeline fuel" as reported
in DOE, EIA, Natural Gas Annual 2020, Table 1. Cubic feet were converted to Btu using 1,031
Btu/ft3. Electricity use was estimated using the following procedure as reported on p. 5-110 of J.
N. Hooker et al., End Use Energy Consumption DataBase: Transportation Sector. The energy
consumption of a natural gas pipeline was taken to be the energy content of the fuel used to drive
the pumps. Some 94% of the installed pumping horsepower was supplied by natural gas. The
remaining 6% of the horsepower was generated more efficiently, mostly by electric motors. The
energy consumed by natural gas pipeline pumps that were electrically powered was not known.
In order to estimate the electricity consumed, the Btu of natural gas pipeline fuel consumed was
multiplied by a factor of 0.015.

7. CAR AND LIGHT TRUCK SHARES
In 2011, the Federal Highway Administration (FHWA) changed the methodology for producing
the data on the VM-1 Table in the annual Highway Statistics publication. Historically, VM-1
included individual categories for passenger cars and 2-axle, 4-tire trucks. VM-1 included the
vehicle miles of travel (VMT), registrations, fuel use, and fuel economy of passenger cars and 2axle, 4-tire trucks. After the methodology change, the categories of light vehicles on VM-1
changed to Light-Duty Vehicles with Short wheelbase (less than or equal to 121 inches) and
Light-Duty Vehicles with Long Wheelbase (over 121 inches). As some passenger cars have long
wheelbases and some 2-axle, 4-tire trucks have short wheelbases, the categories of cars and 2axle, 4-tire trucks are no longer available. Despite these changes, there are many transportation
analysts who require information on cars and 2-axle, 4-tire trucks. Thus, a new methodology to
estimate the data in these categories was developed for years 2009 through 2018.

CONVERSIONS
A Note about Heating Values

The heat content of a fuel is the quantity of energy released by burning a unit amount of
that fuel. However, this value is not absolute and can vary according to several factors. For
example, empirical formulae for determining the heating value of liquid fuels depend on the fuels'
American Petroleum Institute (API) gravity. The API gravity varies depending on the percent by
weight of the chemical constituents and impurities in the fuel, both of which are affected by the
combination of raw materials used to produce the fuel and by the type of manufacturing process.
Temperature and climatic conditions are also factors.
Because of these variations, the heating values in Table B.4 may differ from values in other
publications. The figures in this report are representative or average values, not absolute ones.
The gross (higher) heating values used here agree with those used by the Energy Information
Administration (EIA).
Heating values fall into two categories, usually referred to as “higher” (or gross) and
“lower” (or net). If the products of fuel combustion are cooled back to the initial fuel-air or fueloxidizer mixture temperature and the water formed during combustion is condensed, the energy
released by the process is the higher (gross) heating value. If the products of combustion are
cooled to the initial fuel-air temperature, but the water is considered to remain as a vapor, the
energy released by the process is the lower (net) heating value. Usually the difference between
the gross and net heating values for fuels used in transportation is around 5 to 8 percent; however,
it is important to be consistent in their use.
The Transportation Energy Data Book has always used gross heating values for fuel
conversion.

Conversion of Constant Dollar Values
Many types of information in this data book are expressed in dollars. Generally, constant
dollars are used–that is, dollars of a fixed value for a specific year, such as 2010 dollars.
Converting current dollars to constant dollars, or converting constant dollars for one year to
constant dollars for another year, requires conversion factors (Table B.17 and
Table B.18). Table B.17 shows conversion factors for the Consumer Price Index inflation factors.
Table B.18 shows conversion factors using the Gross National Product Implicit Price Deflator.

GLOSSARY
Acceleration power – Often measured in kilowatts. Pulse power obtainable from a battery used
to accelerate a vehicle. This is based on a constant current pulse for 30 seconds at no less
than 2/3 of the maximum open-circuit-voltage, at 80% depth-of-discharge relative to the
battery's rated capacity and at 20○ C ambient temperature.
Age – The amount of time a person or thing has existed.
Air Carrier – The commercial system of air transportation consisting of certificated air carriers,
air taxis (including commuters), supplemental air carriers, commercial operators of large
aircraft, and air travel clubs.
Certificated route air carrier: An air carrier holding a Certificate of Public Convenience
and Necessity issued by the Department of Transportation to conduct scheduled interstate
services. Nonscheduled or charter operations may also be conducted by these carriers.
These carriers operate large aircraft (30 seats or more, or a maximum payload capacity of

terminals operated by refining and pipeline companies, and at independent bulk terminals.
Crude oil held in storage on leases is also included; these stocks are known as primary
stocks. Secondary stocks–those held by jobbers dealers, service station operators, and
consumers–are excluded. Prior to 1975, stock held at independent bulk terminals were
classified as secondary stocks.
Petroleum products supplied: For each petroleum product, the amount supplied is
calculated by summing production, crude oil burned directly, imports, and net withdrawals
from primary stocks and subtracting exports.

Plug-in hybrid-electric vehicles (PHEVs) — Hybrid-electric vehicles with high capacity
batteries that can be charged by plugging them into an electrical outlet or charging station.
There are two basic PHEV configurations:
Parallel or Blended PHEV: Both the engine and electric motor are mechanically
connected to the wheels, and both propel the vehicle under most driving conditions.
Electric-only operation usually occurs only at low speeds.
Series PHEVs, also called Extended Range Electric Vehicles (EREVs): Only the
electric motor turns the wheels; the gasoline engine is only used to generate electricity.
Series PHEVs can run solely on electricity until the battery needs to be recharged. The
gasoline engine will then generate the electricity needed to power the electric motor. For
shorter trips, these vehicles might use no gasoline at all.
Processing Gain – The amount by which the total volume of refinery output is greater than the
volume of input for given period of time. The processing gain arises when crude oil and
other hydrocarbons are processed into products that are, on average, less dense than the
input.
Processing Loss – The amount by which the total volume of refinery output is less than the volume
of input for given period of time. The processing loss arises when crude oil and other
hydrocarbons are processed into products that are, on average, denser than the input.
Proved Reserves of Crude Oil – The estimated quantities of all liquids defined as crude oil, which
geological and engineering data demonstrate with reasonable certainty to be recoverable in
future years from known reservoirs under existing economic and operating conditions.

Rail –

Amtrak (American Railroad Tracks): Operated by the National Railroad Passenger
Corporation of Washington, DC. This rail system was created by President Nixon in 1970,
and was given the responsibility for the operation of intercity, as distinct from suburban,
passenger trains between points designated by the Secretary of Transportation.
Class I freight railroad: Defined by the Interstate Commerce Commission each year
based on annual operating revenue. A railroad is dropped from the Class I list if it fails to
meet the annual earnings threshold for three consecutive years.
Commuter railroad: Those portions of mainline railroad (not electric railway)
transportation operations which encompass urban passenger train service for local travel
between a central city and adjacent suburbs. Commuter railroad service–using both
locomotive-hauled and self-propelled railroad passenger cars–is characterized by multitrip tickets, specific station-to-station fares, and usually only one or two stations in the
central business district. Also known as suburban railroad.
