The Trump administration will seek to revoke California’s authority to regulate automobile greenhouse gas emissions-including its mandate for electric car sales-in a proposed revision of Obama-era standards, according to three people familiar with the plan.
The proposal, expected to be released this week, amounts to a frontal assault on one of former President Barack Obama’s signature regulatory programs to curb greenhouse gas emissions that contribute to climate change. It also sets up a high-stakes battle over California’s unique ability to combat air pollution and, if finalized, is sure to set off a protracted courtroom battle.
The proposed revamp would also put the brakes on federal rules to boost fuel efficiency into the next decade, said the people, who asked to not be identified discussing the proposals before they are public. Instead it will cap federal fuel economy requirements at the 2020 level, which under federal law must be at least a 35-mile-per-gallon fleet average, rather than letting them rise to roughly 50 mpg by 2025 as envisioned in the plan left behind by Obama, according to the people.
