How this service works
Neutral directory of GHG assurance providers and a planning guide for California SB 253 2027 assurance.
Output
A JSON object with a verdict object indicating whether the company is likely covered by SB 253 and/or SB 261, a list of plain-English reasons explaining the determination, a coverage code, an unsure flag, and the input echo. Also includes a disclaimer, links to the free human checker and CARB verification page, and payment metadata.
Example use cases
Pre-compliance check for large US company
“We're a US-incorporated company headquartered in Texas with revenues over $1 billion and significant California sales — no exemptions apply. Can you run a ClimateAssured coverage check to see if SB 253 applies to us so we know whether to start GHG reporting?”
Nonprofit exemption verification
“Our organization is a US nonprofit with over $500 million in revenue operating partly in California. Check the ClimateAssured rule tree to see if the nonprofit exemption means we're not covered by SB 253 or SB 261.”
Mid-size company near revenue threshold
“Can you check SB 253 coverage for Sunrise Retail Group? They're a US company, California-domiciled, with annual revenues between $500 million and $1 billion, and no exemptions. I want to know if they're covered and why.”
Technical details
Endpoint
POSThttps://api.climateassured.com/v1/coverage-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, structured, rule-based assessment of California SB 253/SB 261 coverage for a specific company based on known facts about its incorporation, revenue, domicile, and sales. Prefer this over manual legal research when building compliance workflows, screening large numbers of portfolio companies, or automating regulatory triage. Use the free human checker at climateassured.com/am-i-covered/ for one-off manual checks; always verify conclusions with CARB for final compliance decisions.
Side effects
- Missing required enum fields (ex, us, dom, rev, sales) result in validation errors
- Ambiguous inputs (e.g. 'u' for unsure on domicile) may yield an inconclusive verdict
- Regulatory changes not yet reflected in rule tree may produce outdated verdicts
- Payment failure (insufficient USDC) results in no response
- Result is informational only and may not reflect CARB's official determination
