In a 2-1 decision, the court concluded that FERC’s environmental impact statement did not contain adequate information regarding the indirect greenhouse gas emissions that would result from combustion at downstream power plants. According to the majority, FERC “should have either given a quantitative estimate of the downstream greenhouse gas emissions […] or explained more specifically why it could not have done so.” However, the court “[did] not hold that quantification of greenhouse-gas emissions is required every time those emissions are an indirect effect of an agency action [because] in some cases quantification may not be feasible.” Thus, the National Environmental Policy Act (NEPA) must be applied on a case-specific basis.
