President Trump is expected to sign an executive order today to dismantle a slew of climate rules put in place by President Obama. The executive order will instruct the Environmental Protection Agency to review Obama’s rules limiting power plant emissions—the first step to the regulation’s eventual elimination. The order is also expected to direct the Interior Department to lift Obama’s moratorium halting new coal leases on federal land.The Bureau of Land Management will be instructed to review regulations limiting hydraulic fracturing. Obama’s regulations limiting methane emissions will be dismantled. The executive order is also expected to end President Obama’s 2013 climate action plan, which outlined the federal government’s approach to curbing climate change. Environmental groups are vowing to fight the executive order. Protests are planned for this afternoon in Washington, D.C.
