As we wrote about previously, in February 2016 the International Civil Aviation Organization (ICAO) proposed international standards to limit the emissions of greenhouse gas (GHG) emissions from airplane engines.  Last week, the EPA finalized the first step to create domestic emissions standards for airplanes when it officially found that GHG emissions from certain types of aircraft engines contribute to climate change.  Now that EPA has issued this determination — known as an “Endangerment Finding” — it is required to regulate these emissions under the Clean Air Act.  EPA may propose new domestic emissions rules before the end of President Obama’s term and it has announced the limits will be at least as stringent as the international standards ICAO proposed in February.

Murray Energy Corp. Suit Allowed to Proceed

Upon publication of the proposed “Carbon Pollution Emission Guidelines for Existing Stationary Sources: Electric Generating Units” (also referred to as the Proposal or Clean Power Plan), on June 18, 2014, Murray Energy Corp. filed a petition for writ of extraordinary relief, alleging that the United States Environmental Protection Agency (USEPA) does not have the legal authority under the Clean Air Act to finalize performance standards for existing sources under Section 111(d).  Murray Energy Corporation v. U.S. Environmental Protection Agency, No. 14-1112 (D.C. Cir. filed June 18, 2014).  A week later, on June 25, 2014, a group of nine states filed an amici curiae brief, urging the D.C. Circuit to grant Murray Energy’s petition for writ, prohibiting USEPA to continue with its rulemaking.
