United States · California · Scope 1–3

California's rules reach far beyond California.

There's no single federal law — instead California passed its own, and because so many companies do business there, it affects firms nationwide. Under SB 253, any company with over USD 1 billion in revenue doing business in California reports Scope 1, 2 and (from 2027) Scope 3. Under SB 261, companies over USD 500 million publish a climate-risk report every two years. Even below these thresholds, a large customer may ask you for the data.
