Two environmental organizations have again taken the United States Environmental Protection Agency (“EPA”) to task for failing in its mandatory duty to determine whether greenhouse gases from aircraft engines cause or contribute to air pollution that may reasonably be anticipated to endanger public health or welfare (“Endangerment Finding”), and, if so, to propose and adopt standards to limit those emissions.  See Clean Air Act (“CAA”), 42 U.S.C. § 7571(a)(2)(A) (also referred to as “Section 231”).  

Earth Justice and Friends of the Earth originally petitioned EPA in 2007, pursuant to CAA Section 231, which directs EPA to study air pollutants from aircraft “to determine (A) the extent to which such emissions affect air quality in air quality control regions throughout the United States, and (B) the technological feasibility of controlling such emissions.”  Section 231(a)(1).  Under subsections (a)(2) and (3), if EPA finds that emissions from aircraft and aircraft engines cause or contribute to “air pollution which may reasonably be anticipated to endanger public health or welfare,” it “shall” propose and issue standards to control such emissions.  In 2010, EPA had still not responded to their 2007 Petition.

When the U.S. Environmental Protection Agency issued its final finding that emission of six greenhouse gases endangered the public’s health and the environment because of their effect on climate change, the business community wondered how it should respond to the news.  At first glance, there seems to be blinding maze of legal and policy issues that will affect business decisions.  Although far from clear, there is a way out of the maze – although businesses with significant greenhouse gas emissions should be prepared to tackle the important issues that the Endangerment Finding raises.

Businesses Need to Take a Deep Breath (Irony Intended)

The road to the endangerment finding began in 2007, when the U.S. Supreme Court decided in Massachusetts v. EPA that carbon dioxide and other greenhouse gases constituted “air pollutants” under the Clean Air Act.  To most savvy businessmen this was a clear signal to start planning how their businesses would cope with the establishment of limits on emission of greenhouse gases.  Although the Bush Administration EPA successfully sat on the issue, when the Obama Administration took office, most companies recognized that an endangerment finding would top the EPA’s list of major environmental actions.  Thus, EPA’s announcement this past April of its proposed finding and its announcement of the final endangerment finding should have come as no surprise to anyone who has been monitoring this issue.

The key thing for businesses to remember is that the endangerment finding by itself does not regulate the emission of greenhouse gases from any source, large or small.  That being said, it does have a direct impact on mobile sources (because of section 202(a) of the Clean Air Act), with the EPA planning on issuing its final “light-duty vehicle” greenhouse gas emissions rule some time in Spring 2010.
