How Much Again? Interagency Working Group Revived to Quantify Social Costs of Greenhouse Gases

On August 13, 2025, the U.S. District Court for the Central District of California denied a motion for preliminary injunction filed by a coalition of business groups seeking to halt implementation of California’s corporate climate disclosure laws—SB 253 and SB 261. Senate Bill 253 (SB 253 )¹ requires entities that do business in California and whose total annual revenue exceeds $1 billion to disclose Scope 1 and 2 greenhouse gas (GHG) emissions beginning in 2026 (covering 2025 data), and Scope 3 emissions beginning in 2027 (covering 2026 data). Senate Bill 261 (SB 261),² passed as part of the same Climate Accountability legislative package, requires entities that do business in California and whose total annual revenue exceeds $500 million to publicly disclose the business’s climate-related financial risks and measures taken to reduce or adapt to that risk online every two years, beginning in 2026.³

Beginning on Monday, there have been a flurry of executive orders from the Trump administration reversing Biden-era energy policies, emphasizing oil and gas production, lifting the liquified natural gas (LNG) export permitting pause and withdrawing from all accords and commitments under the United Nations Framework Convention on Climate Change (UNFCCC) including the Paris climate agreement. The orders also target electric vehicles (EVs), wind energy, international climate aid and the use of the social cost of carbon in agency decision making. For close tracking of these orders and more to come, visit the Akin Trump Executive Order tracker. Concurrently, President Trump’s nominees for the Department of the Interior (DOI), Department of Energy (DOE) and Environmental Protection Agency (EPA) have each passed their initial rounds of committee confirmation votes, and now await votes before the Senate floor.
