The California Air Resources Board (CARB) released a preliminary list of companies it believes may be subject to the state’s new climate disclosure regime, which imposes significant disclosure duties on large United States entities “doing business in California”—even if the business they do in California is not itself large. CARB’s list comes after a federal trial court declined to stay the rules, with the first compliance deadline set to go into effect January 2026 even as the agency’s implementing regulations remain under development.
