On October 1, 2024, California Governor Gavin Newsom signed a new climate disclosure law, requiring large companies operating in the state to report emissions and climate-related financial risks. The law, incorporating SB 253 and SB 261, mandates businesses with over $1 billion in revenue to disclose emissions from all scopes, while those with over $500 million must report on climate-related risks. Despite earlier concerns, the original 2026 start date remains intact. Key amendments include more flexible reporting for Scope 3 emissions and consolidated reporting at the parent company level, solidifying California’s role in advancing corporate climate transparency.
