SACRAMENTO, Calif. (AP) – Gov. Jerry Brown is further expanding California’s cooperation with the European Union and China on fighting climate change. Brown and the European Union’s climate commissioner announced Tuesday the two governments will begin hosting regular meetings, and work with China, on carbon market cooperation. Carbon markets aim to reduce pollution by putting a price on emissions. California operates one through its cap-and-trade program. Brown’s remarks come during a nearly two-week trip in Europe focused on fighting global warming. Brown has emerged as a foil to President Donald Trump on climate change, forming agreements and partnerships with governments worldwide as the White House backs away from international climate commitments. He’ll end the week at a United Nation’s climate conference in Germany. Brown says he hopes California and the EU can link markets.
