| Scope | OAL approved CARB's initial regulation on 12 Oct 2026, and it took effect at once. The first-year reports cover Scope 1 and 2. The initial regulation requires no assurance; CARB will accept 2026 reports with or without it. A separate CARB rulemaking is setting Scope 3 and assurance from 2027. SB 261 enforcement stays enjoined while the Ninth Circuit appeal runs. |
