California on Friday formally proposed a 40 percent slash in the state’s greenhouse gas emissions, minutes after President Trump was inaugurated.

The state’s Air Resources Board said that 40 percent cut by 2030, compared with 1990 levels, would be the most ambitious climate goal in North America.

“Climate change is impacting California now, and we need to continue to take bold and effective action to address it head on to protect and improve the quality of life in California,” Mary Nichols, the board’s chairwoman, said in a statement.

“The plan will help us meet both our climate and our clean air goals in the coming decades and provide billions of dollars in investments to cut greenhouse gases, smog and toxic pollution in disadvantaged communities throughout the state,” she said.

“It is also designed to continue to drive creative innovation, generating good new jobs in the growing clean technology sector.”

The plan sets up a contrast with Trump, who was inaugurated about 30 minutes before California released its plan.

Trump has said climate change is a hoax, and Scott Pruitt, his nominee to lead the Environmental Protection Agency, has sued the agency to stop Obama regulations repeatedly.

Pruitt said at a confirmation hearing this week that he would consider ending California’s decades-old authority to enforce its own limits on emissions from cars and trucks, alarming the state’s liberal leadership.

The California plan proposed Friday would extend its cap-and-trade program for greenhouse gases through 2030, cut the carbon intensity of fuels used for transportation and put more than 4 million zero-emission vehicles on the roads.
