As such, later today President Trump is set to sign a sweeping new "Energy Independence" executive order aimed at promoting domestic oil, coal and natural gas production by reversing much of Obama's efforts to address climate change via his "Clean Power Plan".

Obama's Clean Power Plan was designed to cut carbon dioxide emissions from electricity by 32% by 2030 compared to 2005 levels and resulted in the collapse of the coal industry, including several large bankruptcies.  That said, the initiative has been in legal limbo since the Supreme Court stayed it while it was reviewed by a federal appeals court. The Trump administration now is expected ask that court to put the matter on hold to allow it time to revise or undo the measure -- an action environmentalists have vowed to challenge.

Here is a summary of what Trump's EO will seek to accomplish, via Axios:

Begin undoing the EPA Clean Power Plan than mandates cuts in carbon emissions from coal-fired power plants.
 
Undo several policies that wove climate change into federal decision-making, such as the Obama administration's tally of a metric called the social cost of carbon, and a White House directive that agencies factor climate change into a range of permitting decisions.
 
Direct the Interior Department to end its moratorium on coal leasing on federal lands.
