U.S. Supreme Court Denies Request to Reinstate Injunction of Social Cost of Greenhouse Gases
On May 26, 2022, the U.S. Supreme Court issued an order in Louisiana v. Biden denying a request to intervene and reinstate a district court order that had blocked the administration from using a key climate metric, known as the social cost of greenhouse gas emissions (SC-GHGs).

EPA Proposes “Good Neighbor” Plan Addressing Regional Ozone Transport for the 2015 Ozone National Ambient Air Quality Standard
On April 6, 2022, the U.S. Environmental Protection Agency (EPA) is scheduled to publish its proposed Federal Implementation Plan Addressing Ozone Transport for the 2015 Ozone National Ambient Air Quality Standards (NAAQS), otherwise known as the latest iteration of EPA’s Cross-State Air Pollution Rule or “Good Neighbor” Plan. The proposal would subject 26 upwind states to the “good neighbor” or “interstate transport” provision of the Clean Air Act because EPA is proposing to find that nitrogen oxide (NOx) emissions, which are a precursor to ozone formation, from the upwind states significantly contribute to downwind states’ attaining and maintaining the 2015 ozone NAAQS.
