Trump signs executive order unwinding Obama climate policies

President Trump signed a long-promised executive order to nullify President Barack Obama’s climate change efforts and revive the coal industry, effectively ceding American leadership in the international campaign to curb the dangerous heating of the planet. At a ceremony, Mr. Trump directed the Environmental Protection Agency to start the complex and lengthy legal process of withdrawing and rewriting the Obama-era Clean Power Plan, which would have closed hundreds of coal-fired power plants, frozen construction of new plants and replaced them with vast new wind and solar farms. The order will steer clear, however, of several controversial climate policies from Obama's tenure, including the United States' participation in the Paris climate accord and EPA's so-called endangerment finding, which triggered climate regulations under the Clean Air Act.
