The 2022 EPA Automotive Trends Report: Greenhouse Gas Emissions, Fuel Economy, and Technology since 1975

This annual report is part of the U.S. Environmental Protection Agency’s (EPA) commitment to provide the public with information about new light-duty vehicle greenhouse gas (GHG) emissions, fuel economy, technology data, and auto manufacturers' performance in meeting the agency’s GHG emissions standards. EPA has collected data on every new light-duty vehicle model sold in the United States since 1975, either from testing performed by EPA at the National Vehicle Fuel and Emissions Laboratory in Ann Arbor, Michigan, or directly from manufacturers using official EPA test procedures. These data are collected to support several important national programs, including EPA criteria pollutant and GHG standards, the U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) Corporate Average Fuel Economy (CAFE) standards, and vehicle Fuel Economy and Environment labels. In model year 2021, the average estimated real-world CO₂ emission rate for all new vehicles fell by 2 g/mi to 347 g/mi, the lowest ever measured. Real-world fuel economy remained at a record high 25.4 mpg. Since model year 2004, CO₂ emissions have decreased 25%, or 114 g/mi, and fuel economy has increased 32%, or 6.1 mpg. Over that time, CO₂ emissions have improved in fourteen of seventeen years.
