Which of the 2 laws applies Tests total annual revenue against both statutory thresholds — more than 1000 (USD millions) for SB 253, more than 500 for SB 261 — instead of the California-only revenue figure people reach for first.
US formation test SB 253 and SB 261 reach entities formed under the laws of a US state doing business in California. A group whose filing entity is formed outside the United States is told Neither, with the reason.
The moved SB 253 date Returns 2026-11-10 — CARB moved the first Scope 1 and Scope 2 report from 10 August 2026 to 10 November 2026 — and the days left from the date you type.
SB 261 enforcement status Says plainly that the statutory 2026-01-01 SB 261 date is not being enforced while a Ninth Circuit injunction is on appeal, and that CARB will set an alternate date, so nobody reports to a dead date.
Per-entity fee total Multiplies CARB's fees by your count of covered entities: 3 entities at 1,250 (USD millions) of revenue owe 9,318 for SB 253 plus 4,209 for SB 261 = 13,527 in fees, assessed 10 September 2026.
Scope 3 lead time Flags that Scope 3 reporting and assurance are anticipated to begin in 2027, so the inventory work is scoped in the same quarter as the first Scope 1 and Scope 2 filing.
