"California released new measures to fight climate change within minutes of Donald Trump being sworn in as U.S. president on Friday, signaling the state's commitment to be the nation's environmental steward under an administration that has questioned the reality of global warming.
California officials said it was a coincidence that the plan was released 37 minutes after the inauguration. The state outlined how it would achieve its goal of cutting output of heat-trapping greenhouse gases 40 percent below 1990 levels by 2030.
The plan drew battle lines for an expected clash with Trump over climate change, including a fight over the state's decades-old authority to set emissions limits that are far stricter than those in many other parts of the United States."
