Overview

In December 2021, EPA finalized revised national greenhouse gas (GHG) emissions standards for passenger cars and light trucks for Model Years 2023- 2026. The final standards would achieve significant GHG emissions reductions along with reductions in other criteria pollutants. The rule 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
