Abstract

The Supreme Court decision on Mass. v. EPA in April 2007, stated that carbon dioxide (CO2) meets the CAA definition of air pollution and that EPA must decide whether or not greenhouse gases cause endangerment (or whether scientific uncertainty precludes EPA from making a reasoned judgment). The basis for this decision must be the statutory criteria laid out under Section 202 of the CAA. In December 2007, EPA developed and submitted to OMB a proposal for an endangerment finding (in conjunction with a proposed GHG transportation rulemaking). It was withdrawn a few weeks later following passage of the Energy Independence and Security Act. OAR is now working to issue a proposed endangerment determination.
