Proposed Rule to Revise Existing National GHG Emissions Standards for Passenger Cars and Light Trucks Through Model Year 2026
On this page:
The Environmental Protection Agency (EPA) proposed to strengthen federal greenhouse gas (GHG) emissions standards for passenger cars and light trucks by setting stringent requirements for reductions through Model Year (MY) 2026. The proposed 2023-2026 MY standards would achieve significant GHG emissions reductions along with reductions in other pollutants. The proposal would result in substantial public health and welfare benefits, while providing consumers with savings from lower fuel costs. The proposal would incentivize technology available today to make vehicles cleaner and to encourage more hybrid and electric vehicle technology.
