The California Air Resources Board (CARB) and major automakers on Monday confirmed they had finalized binding agreements to cut vehicle emissions in the state, defying the Trump administration's push for weaker curbs on tailpipe pollution.

The agreements with carmakers, including Ford Motor Co., Volkswagen AG, Honda Motor Co. and BMW AG, were first announced in July 2019 as voluntary measures, prompting anger from U.S. President Donald Trump.

A month later, the Justice Department opened an antitrust probe of the agreements, only to end it without action.
