Clean Energy Fuels Corp. v. EPA

The D.C. Circuit granted petitioner Clean Energy Fuels Corp.’s unopposed motion to dismiss it from consolidated proceedings challenging the U.S. Environmental Protection Agency’s (EPA’s) September 2011 rule establishing greenhouse gas emissions and fuel efficiency standards for medium- and heavy-duty engines and vehicles.  Clean Energy Fuels, which was described in the proceedings as “the leading provider of natural gas for transportation in North America,” had objected to the use of a higher global warming potential (GWP) for methane from mobile sources than for methane from stationary sources. This discrepancy was rectified in EPA’s November 2013 amendment to the Greenhouse Gas Reporting Rule.
