Two statutes, two different obligations
SB 253 is an emissions reporting law and SB 261 a climate-risk reporting law. They reach different revenue thresholds and are satisfied by different documents.
- SB 253 — Scope 1 and 2 emissions, then Scope 3, with assurance phased in.
- SB 261 — A public report on climate-related financial risk.
- Scope — Entities doing business in California above the statutory revenue thresholds.
