"WASHINGTON - A federal appeals court on Friday rejected a challenge by California and 16 other states to the Trump administration’s decision to revise strict U.S. vehicle emissions and fuel efficiency rules put in place under former President Barack Obama.
The states sued in May 2018 after the Trump administration reopened a review of the vehicle efficiency standards through 2025. In its final weeks in office, the Obama administration sought to cement the rules in place by completing the “midterm review” more than a year ahead of the April 2018 deadline.
The challenge was seen as the longest shot in a multi-pronged legal effort by states, which are fighting the Trump proposal on a variety of rules. They argue stringent vehicle efficiency rules are crucial to addressing climate change and will save consumers in fuel costs."
