President Donald Trump will take the most significant step yet in obliterating his predecessor's environmental record Tuesday, instructing federal regulators to rewrite key rules curbing U.S. carbon emissions.
The sweeping executive order also seeks to lift a moratorium on federal coal leasing and remove the requirement that federal officials consider the impact of climate change when making decisions.
The order sends an unmistakable signal that just as President Barack Obama sought to weave climate considerations into every aspect of the federal government, Trump is hoping to rip that approach out by its roots.
"This policy is in keeping with President Trump's desire to make the United States energy independent," said a senior administration official who briefed reporters on the directive Monday evening and asked for anonymity to speak in advance of the announcement. "When it comes to climate change, we want to take our course and do it in our own form and fashion."
Some of the measures could take years to implement and are unlikely to alter broader economic trends that are shifting the nation's electricity mix from coal-fired generation to natural gas and renewables. The order is silent on whether the United States should withdraw from the 2015 Paris climate agreement, under which it has pledged to cut its greenhouse gas emissions between 26 and 28 percent by 2025 compared to 2005 levels, because the administration remains divided on that question.
