Ceres filed an amicus curiae brief in the US Court of Appeals for the Ninth Circuit supporting California’s climate disclosure laws, positioning them as market-transparency measures with broad backing from businesses, investors, and advocates amid litigation seeking to block the statutes. The brief responds to a lawsuit brought by the US Chamber of Commerce and other trade associations and cites years of corporate and institutional investor advocacy for standardized climate disclosures, including a letter from 35 businesses supporting full funding for implementation. It addresses SB 253 (Climate Corporate Data Accountability Act) and SB 261 (Climate-Related Financial Risk Act), under which companies with more than USD 1 billion in annual revenue would disclose direct and indirect greenhouse gas emissions, and companies with more than USD 500 million in revenue would publish biennial climate-related financial risk reports.
