California's three-bill climate disclosure stack — SB 253 (Climate Corporate Data Accountability Act, Wiener), SB 261 (Climate-Related Financial Risk Act, Stern), SB 219 (2024 amendments) — pulls thousands of US-formed entities 'doing business in California' (Franchise Tax Board test) with global revenue above the thresholds into mandatory disclosure. SB 253 thresholds and scope — global total annual revenue >$1B; subsidiaries roll up to ultimate parent for revenue test but report consolidated. SB 253 requires GHG Protocol Corporate Standard-aligned Scope 1 (direct: combustion, process, fugitive, fleet), Scope 2 (purchased electricity/steam/heat/cooling, both location- and market-based), and Scope 3 (15 categories: purchased goods/services, capital goods, fuel/energy, upstream/downstream transport, waste, business travel, employee commute, leased assets, processing/use/end-of-life of sold products, franchises, investments) emissions. Reporting timeline — Scope 1+2 from 2026 for FY2025 with limited third-party assurance, reasonable assurance by 2030; Scope 3 from 2027 for FY2026 with limited assurance by 2030; Scope 3 safe harbour through 2030 for good-faith estimates. CARB-published platform with filing fees. Penalties up to $500,000 per reporting year. SB 261 thresholds and scope — global revenue >$500M; insurance companies exempt. Biennial climate-related financial risk report aligned with TCFD recommendations (now IFRS S2) covering four pillars (governance, strategy with 1.5°C and 3°C+ scenario analysis, risk management, metrics and targets including Scope 1/2/3 where material and transition plan). First report due January 1, 2026 covering FY2024-2025; biennial thereafter; published on company website with link reported to CARB. Penalty up to $50,000 per reporting year. SB 219 refinements — extended CARB rulemaking deadline; allowed consolidated reporting at parent level; preserved Scope 3 safe harbour; permitted CARB to align with federal/international frameworks (CSRD ESRS E1, IFRS S2, SEC climate rule) to reduce duplication. Assurance providers under SB 253 must meet CARB qualification (AICPA, ISO 14065, equivalent). Implementing regulations finalized through 2025-2026.

How V5 handles it

Score your compliance gap — then download the validation pack.

A guided self-assessment walks you against the regulator clauses that apply to your industry. The validation pack — IQ/OQ/PQ scripts, traceability matrix, risk assessment, intended-use statement — generates from the same evidence so you can hand it to an auditor on day one.

Document control with hard kiosk-level training enforcement.

Versioned SOPs are only useful if operators are actually trained on the current version. V5 enforces it at the kiosk.

QMS — quality engineered into every action, not bolted on.

Because V5 owns the operator action, the QMS sees the data the second it’s captured — not at the end of the shift.

Supplier portal — chase nothing. Score everything.

Suppliers log in, see what you need, submit it against your spec, and watch their scorecard. SCARs are raised, replied to and closed in the portal — not in your inbox.
