Federal judges consider second review of Texas LNG projects amid climate change and air quality concerns.

Federal judges are deciding whether to order a second review of two liquefied natural gas export projects in Texas that could affect climate change and air quality. The hearing, held at the U.S. Court of Appeals for the District of Columbia Circuit, is part of a larger debate over how the Federal Energy Regulatory Commission (FERC) should use the social cost of carbon (social and economic damage) in its decision to green-light energy projects. The D.C. Circuit had previously ordered FERC to redo parts of its analysis of Texas LNG and Rio Grande LNG, as well as an associated natural gas pipeline, to explain why the agency chose not to use this metric. The City of Port Isabel and Sierra Club argue that FERC has not done enough to minimize environmental harm in approving the projects.
