SB 253 — California

10 November 2026 is proposed.
Are you ready?

SB 253 requires California-nexus companies with global revenue over $1B to disclose Scope 1 and 2 emissions. CARB has proposed 10 November 2026 for the first SB 253 report — Scope 1 and 2 for the prior fiscal year. The date is not final: the modified regulation closed public comment on 11 August 2026 and still requires OAL approval. An earlier date of 10 August 2026 was approved and then withdrawn before it took effect. ThemisIQ can have your inventory complete and the CARB template pre-filled in days — not months.

Greenwashing risk — Canada

Every carbon claim now needs proof behind it.

Canada's Competition Act now targets unsubstantiated environmental claims. If you state “net zero,” “carbon neutral,” or “emissions reduced by X%,” the burden is on you to prove it — under a reverse-onus standard, the company making the claim must show it is adequately and properly substantiated, not the regulator. An audit-trailed GHG inventory is that proof.

Reverse onus — you must substantiate the claim
Penalties up to $10M or 3% of global revenue
Applies to marketing, websites, and reports
ThemisIQ gives every figure a documented, defensible basis
Claim vs. proof
"We are carbon neutral"
Needs: Scope 1 + 2 inventory with cited emission factors
"Emissions down 30%"
Needs: Prior-year baseline + current inventory, same methodology
"Science-based target"
Needs: Verified baseline inventory - the foundation for any target
"Low-carbon operations"
Needs: Intensity figures benchmarked and source-documented
Competition Act (Bill C-59, 2024; amended by C-15, 2026). Requirements are evolving and subject to a constitutional challenge — confirm your obligations with counsel.

One location = one site with its own electricity supply. All of that site’s energy goes in together — electricity, gas, vehicle fuel, refrigerants — so a site with separate gas and electricity accounts is still one location.
