Regulations aren't one-size-fits-all. Claritas ESG instantly filters out the noise and builds a specific requirements checklist based on your revenue and location.
CARB Climate Checklist Generator
Answer a few questions on revenue, locations and operations, and Claritas ESG turns California Air Resources Board (CARB) guidance and climate disclosure rules into a tailored checklist with reporting timelines and assurance expectations.
Multi-jurisdiction Intelligence
See how California climate disclosure requirements overlap with CSRD, SEC, and investor expectations—eliminating duplicate work.
Live Legal Status Tracking
Stay updated on enforcement changes, court rulings (like the SB 261 injunction), and regulatory amendments without manually tracking legislation.
The 2026 reporting crunch
has already started.
California is moving ahead, EU rules already apply to many US groups, and assurance is ramping up. Yet most teams are still trapped in Excel.
California SB 253 - Emissions disclosure
>$1B revenue doing business in California must disclose Scope 1 & 2 from 2026 and Scope 3 from 2027 with assurance that ramps from limited to reasonable.
California SB 261 - Climate-related financial risk
Currently enjoined (paused) by the 9th Circuit. >$500M revenue companies should monitor the appeal, as TCFD-style reporting requirements could reinstate quickly if the injunction is lifted.
CSRD & EU reach
US parents and subsidiaries with EU operations fall into CSRD between 2025-2028, including double materiality assessments and detailed Scope 3 expectations.
Greenwashing enforcement
SEC penalties, state AG actions, and class actions are rising; promises without defensible data and documentation are a liability.
California Climate Reporting
Critical milestones for SB 253/261. The transition to defensible, audit-ready documentation starts now.
System Build
Final window to migrate from spreadsheets to audit-ready data infrastructure.
Initial Reports
SB 253/261 reporting begins. Limited assurance for Scope 1 & 2 emissions.
Full Assurance
Scope 3 disclosures required. Assurance level escalates to reasonable.

Why teams keep getting stuck
These aren't philosophical problems—they're workflow problems. Claritas ESG provides the documentation layer you're missing.
Scope 3 is a data & methodology maze
15 GHG categories, supplier gaps, and spend-based shortcuts that fail assurance. Teams need documented reasoning for Scope 3 emissions disclosure – scoping, estimation, and improvement over time.
Spreadsheets everywhere, audit trails nowhere
ESG data across Excel, drives, and slide decks. Version control is fragile. Auditors and California climate reporting rules expect traceable evidence, not screenshots.
Assurance readiness is an afterthought
Limited assurance can run $45k-$60k/year; reasonable can reach $115k-$235k+. Without documentation and links to standards, work comes back instead of getting signed.
Internal alignment breaks down
Finance, sustainability, risk, and legal interpret standards differently. Without a shared, explainable workspace, weeks disappear to email threads and rewrites.

Existing Data Sources
Systems you already have
Decode California climate disclosure laws (SB 253, SB 261, SB 219)
- How do SB 253 and SB 261 interact with SEC, CDP and CSRD climate disclosure requirements?
- Understand "doing business in California" thresholds with citations.
- Keep a documented Q&A trail to share with legal and the Board.
Design and defend Scope 3 methodology
- Identify likely material categories by sector and guidance.
- Draft methodology notes with included categories, data sources, and multi-year improvement plans.
- Keep everything in one place so assurance teams can follow your logic.
Build consistent, cited language for reports
- Generate first drafts for climate risk sections, SB 261 narrative, CSRD-aligned disclosures, supplier FAQs.
- Every paragraph links back to standards or your own documented policies.
Align finance, sustainability, and legal
- Use one workspace where sustainability frames requirements, finance checks consistency, legal reviews regulatory text, and audit validates readiness.
Turn a $677k/year cost into a repeatable process
Cut senior time spent interpreting standards, reduce assurance back-and-forth, and keep consultants focused on high-value tasks.
From the first reporting cycle
“Our first Scope 3 round almost broke us. With Claritas, the second round felt like we finally had a brain for the regulations. We reused last year's reasoning.”

Frequently Asked Questions
Are California SB 253 and SB 261 delayed or paused?
SB 261's enforcement is currently paused by a Ninth Circuit injunction, and parts of SB 253 may still shift as CARB finalises climate disclosure rules. But Scope 1, 2 and 3 emissions disclosure, climate-related financial risk reporting, and third-party assurance are not going away. Claritas ESG helps you use this time to get your methodology, documentation and language ready instead of waiting for the next headline.
Do you provide a California climate disclosure requirements checklist?
Claritas ESG can turn SB 253, SB 261 and CARB climate reporting guidance into a practical, living checklist for your company. You can ask questions like "What are the California climate disclosure requirements for Scope 3?" or "What does CARB expect in an SB 261 climate-related financial risk report?" and capture the answers, assumptions and citations in one workspace.
Do you replace our carbon accounting or ESG platform?
No. Claritas sits on top of your existing systems. You still use your data warehouse, carbon tools, and spreadsheets to calculate numbers. Claritas is where you interpret rules, document methodology, and generate cited language.
Do you "solve" Scope 3 for us?
We do not create supplier data. Claritas helps prioritize categories, pick methods, and document assumptions with clear references to standards and guidance - what auditors and regulators look for.
Are you only for companies in California?
No. We have large knowledge base of international regulations but focus on US companies that need to deal with California rules, CSRD, ISSB/IFRS S2, TCFD, and investor expectations. California is a proxy for where regulation is heading.
How fast can we see value?
Most teams see value in their first working session: import a disclosure, ask Claritas to review it against standards, and capture clarifications in one place. No months-long implementation needed.
