Trump blocks California rules for greener vehicles and gas-powered car ban

State says it would challenge president's resolution, setting up a battle over California's environmental measures

Donald Trump has blocked California's first-in-the-nation rule banning the sale of new gas-powered cars by 2035, signing a resolution on Thursday to stymie the state's ambitious attempt to tackle the climate crisis by pivoting to greener vehicles.

The state quickly announced it was challenging the move in court, with California's attorney general holding a news conference to discuss the lawsuit before Trump's signing ceremony ended at the White House.

The resolution was approved by Congress last month and aims to quash the country's most aggressive attempt to phase out gas-powered cars. Trump also signed measures to overturn state policies curbing tailpipe emissions in certain vehicles and smog-forming nitrogen oxide pollution from trucks.

California has some of the worst smog and air quality issues in the nation, and has for decades been able to seek waivers from the Environmental Protection Agency that have allowed the state to adopt stricter emissions standards than the federal government.
