“LOS ANGELES — The environmental ministers of Canada and Mexico went to San Francisco last month to sign a global pact — drafted largely by California — to lower planet-warming greenhouse pollution. Gov. Jerry Brown flies to China next month to meet with climate leaders there on a campaign to curb global warming. And a battery of state lawyers is preparing to battle any attempt by Washington to weaken California’s automobile pollution emission standards.
As President Trump moves to reverse the Obama administration’s policies on climate change, California is emerging as the nation’s de facto negotiator with the world on the environment. The state is pushing back on everything from White House efforts to roll back pollution rules on tailpipes and smokestacks, to plans to withdraw or weaken the United States’ commitments under the Paris climate change accord.”
