Regulations for Greenhouse Gas Emissions from Passenger Cars and Trucks
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.
