Vowing to keep the United States on track to meet its emissions-cutting target even without the U.S. government's support, more than a dozen governors, including Brown, representing nearly 40 percent of the U.S. economy by Tuesday, June 6, 2017, had pledged themselves to stay in the climate-change fight despite the Trump administration's withdrawal from the Paris climate accords last week.
