On Friday, California approved light-vehicle pollution targets that the Trump administration last week put on hold, setting up a potential face-off between federal and state regulators that could be expensive for automakers and a headache for consumers.
California Air Resources Board members criticized the auto industry for asking federal regulators to reconsider light-vehicle emissions targets for 2022 to 2025.
The board then finalized the vehicle pollution rules for the state, set a mandate for zero-emission sales over the same time period, and ordered its staff to start work on emissions targets for after 2025.
California regulators have a long history of independent efforts to reduce tailpipe pollution from cars and light trucks, and Friday’s move signals the state is prepared to fight the Trump administration.
“We’re going to press on,” Mary Nichols, head of the California Air Resources Board, said during a meeting of the agency here.
The state’s rules on greenhouse gas emissions for light vehicles were written in cooperation with the Obama administration and created a single national standard for new vehicles through 2025.
