US climate disclosure, state by state

There is no federal rule. California’s two laws are the requirement that counts, and the first SB 253 emissions reports are due on 10 November 2026 if CARB’s regulation is approved.[3]

The shape of it

California leads, Washington retreats

California’s laws reach any US company over the revenue thresholds that does business in the state, wherever it is headquartered. That captures much of corporate America.

The federal picture runs the other way: the SEC’s 2024 rule never took effect and is now proposed for rescission.[10]

SB 253: emissions

The Climate Corporate Data Accountability Act requires an annual greenhouse gas inventory: Scope 1 and 2 from 2026 on the prior fiscal year, and Scope 3 from 2027 on a schedule CARB sets.[1]

The first year is lighter

  • No assurance is required for the 2026 report.
  • Companies may report only data they held, or were collecting, as of 5 December 2024. If they held none, they file a letter saying so.
  • Reports may be consolidated at parent level.[3]

Then it tightens

Limited assurance on Scope 1 and 2 follows the first year, moving to reasonable assurance in 2030, when Scope 3 also gets limited assurance.[1] CARB estimated annual fees at $3,106 per entity.[5]

*CARB’s September 2026 guidance says the regulation applies “if approved by OAL”. We had not seen approval by 6 October 2026.

SB 261: climate risk, on hold

SB 261 asks for a climate-related financial risk report every two years, prepared under TCFD, IFRS S2 or an equivalent, from US companies with more than $500m revenue doing business in California.[2]

On 18 November 2025 the Ninth Circuit granted an injunction pending appeal in Chamber of Commerce v. Sanchez, covering SB 261 only.[6] CARB said it would not enforce the 1 January 2026 deadline and ran a voluntary filing docket from 1 December 2025 to 1 July 2026.[7]

Oral argument was heard on 9 January 2026. As of early October 2026 there was no ruling.[8]

What to do now
  • Keep the draft report. If the injunction lifts, CARB will set a new deadline, and work already done under TCFD or IFRS S2 is what you will file.
  • Don’t pause SB 253. The injunction does not touch it.
  • Reuse it elsewhere. An IFRS S2-aligned risk report also serves ISSB jurisdictions and the UK. ISSB →

The SEC rule: adopted, stayed, going

The SEC adopted its climate disclosure rule 3–2 on 6 March 2024 and stayed it a month later while challenges were heard in the Eighth Circuit. On 27 March 2025 it voted to stop defending the rule. The court put the case on hold in September 2025.

On 29 May 2026 the Commission voted unanimously to propose rescinding the rule in full. Comments closed on 3 August 2026; a final vote is the remaining step.[10],[11]

For US-listed companies, no federal rule requires greenhouse gas disclosure. Where a requirement exists, it comes from California, or from abroad through the EU, UK and ISSB regimes.

Questions

US rules, answered

Who must report under California SB 253?

Entities organised in the United States with total annual revenue over $1bn that do business in California.[1] Under CARB’s regulation, revenue is the lesser of the two previous fiscal years. “Doing business” includes being organised or commercially domiciled in California, or California sales above $757,070 (the 2025 figure) or 25% of total sales.[4]

When is the first SB 253 report due?

10 November 2026, for Scope 1 and 2 data on the prior fiscal year, if California’s Office of Administrative Law approves CARB’s regulation. CARB first set 10 August 2026, withdrew the regulation on 23 June and announced the November date the next day.[3],[4]

Does the first SB 253 report need assurance?

No. CARB’s guidance says assurance is not required for the 2026 report.[3] The statute then requires limited assurance on Scope 1 and 2, reasonable assurance from 2030, and limited assurance on Scope 3 from 2030.[1]

What are the penalties under SB 253?

Penalties are capped at $500,000 per reporting year. Scope 3 misstatements made in good faith have a safe harbour, and from 2027 to 2030 Scope 3 penalties apply only to failing to file.[1]

Is SB 261 still in force?

The statute stands, but on 18 November 2025 the Ninth Circuit enjoined it pending appeal, so CARB is not enforcing the 1 January 2026 deadline.[6],[7] Oral argument was heard on 9 January 2026; no decision had been reported by early October 2026.[8] The injunction does not cover SB 253.

What happened to the SEC climate disclosure rule?

Adopted 6 March 2024, stayed 4 April 2024, and never in effect. The SEC voted to stop defending it on 27 March 2025, and on 29 May 2026 proposed rescinding it in full; comments closed on 3 August 2026.[10],[11]
