A proposed Trump administration rule to replace the embattled Obama-era Clean Power Plan would make it easier for coal plant owners to improve their power plants' efficiency without triggering permitting requirements but do little else to reduce emissions of carbon dioxide from those facilities.
The proposal, dubbed the Affordable Clean Energy rule, was unveiled Aug. 21 by the Environmental Protection Agency as a replacement for the Clean Power Plan, which was stayed by the U.S. Supreme Court in 2016.
