EPA released its 50th annual Automotive Trends Report, demonstrating that model year 2023 vehicle fuel economy reached a record high while greenhouse gas emissions dropped to record low levels. The report also shows that all 14 large automotive manufacturers are in compliance with EPA's light-duty GHG program requirements through the MY 2023 reporting period. The new MY 2023 electric vehicles and plug-in hybrid electric vehicles on the road have led to 11% lower CO2 emissions. Despite these significant improvements in local air pollution that have benefited Americans, passenger cars and light trucks still accounted for nearly 17% of total U.S. GHG emissions in 2022, indicating the importance of further reductions in GHG emissions and improvements in fuel economy. This annual report reflects EPA's commitment to provide the public with information about new light-duty vehicle greenhouse gas emissions, fuel economy, technology data, and auto manufacturers' performance in meeting the nation's emissions standards. EPA's annual Automotive Trends Report is separate from the agency's regulatory process.
