Regulations for Greenhouse Gas Emissions from Passenger Cars and Trucks

Overview

In August 2021, EPA proposed to revise existing national greenhouse gas (GHG) emissions standards for passenger cars and light trucks for Model Years 2023- 2026. The proposed standards would achieve significant GHG emissions reductions along with reductions in other criteria pollutants. The proposal would result in substantial public health and welfare benefits, while providing consumers with savings from lower fuel costs.

• Proposed Rule to Revise Existing National GHG emissions standards for passenger cars and light trucks through model year 2026
• Notice of Reconsideration of a Previous Withdrawal of a Waiver for California’s Advanced Clean Car Program (Light-Duty Vehicle Greenhouse Gas Emission Standards and Zero Emission Vehicle Requirements)
• Final Rule: Light-duty Vehicle Greenhouse Gas Program Technical Amendments
• Final Rule: The Safer Affordable Fuel Efficient (SAFE) Vehicles for Model Years 2021-2026
• Final Rule: One National Program on Federal Preemption of State Fuel Economy Standards

Annual Reports

EPA issues annual reports on vehicle manufacturers' performance in meeting the GHG emissions standards, and on light duty fuel economy and GHG emission trends since 1975.
