SACRAMENTO - The California Air Resources Board welcomes the EPA Administrator’s determination that the adopted light-duty vehicle greenhouse gas (GHG) emission standards for model years (MY) 2022-2025 are appropriate.  In 2012, CARB agreed to a national program based on federal adoption of GHG reduction standards as stringent as California’s. EPA’s action today solidifies the continuance of the national program.  

These standards give the auto industry certainty and are the most important basis for the transition to further emission reductions in 2030 and beyond.  

“From the CARB technical team’s perspective, the evidence in support of the standards is robust and definitive” said Dr. Alberto Ayala, CARB’s Deputy Executive Officer.   

This final determination is also timely and important as CARB prepares to consider its own mid-term review of the standards in March. 

“This progress is the result of an unprecedented national partnership between California and U.S. EPA,” said CARB Chair Mary D. Nichols. “We expect that progress to continue under the adopted regulations and we look forward to working together to plan for 2025 and beyond.”
