FERC’s consideration of indirect environmental impacts of the projects it certifies has been heavily debated as the concerns over climate change increase.  Both the National Environmental Policy Act (NEPA) and Natural Gas Act (NGA) require that FERC consider how an interstate natural gas pipeline directly and indirectly affects the human environment.  Although consideration of direct impacts may be a less controversial topic, FERC’s approach with respect to indirect impacts[1] has proven to be more complex.  It is particularly relevant in light of the Council on Environmental Quality’s (CEQ’s) June 2019 proposed guidance, directing how federal agencies should assess project-related greenhouse gas emissions, discussed in detail here and here.  The guidance suggest that FERC should employ a “rule of reason” when considering impacts of greenhouse gas emissions and if FERC lacks adequate information about these emissions, it does not need to quantify them.  This recommended approach, however, seems to conflict with how the D.C. Circuit interpreted FERC’s duty in analyzing greenhouse gas and other indirect emissions in its earlier June 2019 decision Birckhead v. FERC, USCA Case No. 18-1218 (D.C. Cir. 2019).
