Trump revokes California's nation-leading electric vehicle mandate

U.S. President Donald Trump moved on Thursday at a White House signing ceremony to eliminate California's nation-leading vehicle emissions standards, upending the strict rules that had become a template for states across the nation to realize their greenhouse gas ambitions.

During the ceremony, Trump signed a congressional resolution that overturns a California state rule that would have phased out the sale of new gas-powered cars by 2035. The state makes up about 12 percent of the U.S. population.

Its rule has also been adopted by 11 other states and Washington, D.C. 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.
