PDF Version: U.S. Supreme Court Narrows Greenhouse Gas Rules: What It Means for the U.S. Climate Agenda
Case Commented On: Utility Air Regulatory Group v Environmental Protection Agency (EPA), USSC No. 12–1146 (June 23, 2014)
On Monday, the U.S. Supreme Court struck down a portion of the United States’ first regulations for greenhouse gas emissions from industrial sources. The Court held that the Environmental Protection Agency (EPA) may not apply its “Prevention of Significant Deterioration” (PSD) program to new industrial sources on the basis of their greenhouse gas emissions. Instead, EPA can only regulate greenhouse gas emissions from new sources that are already subject to the PSD program because they emit other pollutants.
