On December 30, 2021, the Environmental Protection Agency (EPA) published in the Federal Register (FR Vol. 86, No. 248) a Final Rule for 40 CFR Parts 86 and 600 (EPA-HQ-OAR-2021-0208; FRL 8469-01-OAR). The RIN-2060-AV13 revised 2023 and Later Model Year Light Duty Vehicles requirements for Greenhouse Gas (GHG) Emissions Standards.
The Final Rule is altering the greenhouse gas (GHG) limits to make them more stringent. This action is in response to Executive Order 13990 "Protecting Public Health and the Environment and Restoring Science to Tackle the Climate Crisis" directing EPA to consider whether to propose suspending, revising, or rescinding the standards previously revised under the "The Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule for Model Years 2021-2026 Passenger Cars and Light Trucks". The Final Rule also includes temporary targeted flexibilities to address the lead time of the final standards and to incentivize the production of vehicles with zero and near-zero emissions technology, as well as changing technical amendments for clarification and streamlining. This Final Rule is effective on February 28, 2022.
