AI made for sustainability professionals

You chose sustainability to change the world. Not to drown in regulatory PDFs.

Claritas ESG turns SB 253/261, Scope 3 and CSRD expectations into audit-ready checklists, gap analyses and cited language in minutes instead of weeks—so your team can stop doing document archaeology and get back to impact.

What is Claritas ESG?

Claritas ESG is an AI research platform built for US companies navigating California's Climate Disclosure Laws (SB 253 & SB 261). Unlike standard AI tools, the system uses Grounded Agentic Retrieval-Augmented Generation (RAG) to map corporate disclosures against Scope 3 requirements, TCFD protocols, and assurance standards—providing paragraph-level citations for every claim to eliminate hallucination risk.

Designed for finance, legal, and sustainability teams, the platform automates applicability assessments, methodology documentation, and gap analysis between California mandates and global standards like ISSB and CSRD. The platform supports model-agnostic workflows with no vendor lock-in, allowing teams to toggle between best-in-class AI models from OpenAI, Anthropic, and Google depending on the complexity of the task. Powered by energy-efficient inference (via Groq and Cerebras), Claritas ESG aligns high-performance computing with the environmental mandates it serves.

The only AI platform that reads the regulations as carefully as you do.

Stop cross-referencing PDFs across 20 tabs. Claritas ESG centralizes the world's climate frameworks into one secure, citation-backed intelligence layer. We watched brilliant sustainability professionals spend 60% of their time on document archaeology, doing the job of 5 people and getting burnt by AI hallucinations. Claritas ESG was built with those people in mind.

Unified Framework Intelligence

Don't just search—synthesize. Claritas ESG ingests the entire regulatory landscape (SB 253/261, GHG Protocol, TCFD, CSRD, and more) into one searchable logic layer. Ask how a California requirement overlaps with your European obligations and get the answer in seconds.

Forensic-Level Citations

Generalized AI guesses; Claritas ESG proves. Every answer includes direct links to the specific paragraph and page number of the source regulation. Build your methodology and defend your boundaries with an evidence trail that auditors respect.

Instant Gap Detection

Upload your draft disclosure or data inventory. Our engine scans it against current California requirements to flag missing Scope 3 categories, insufficient risk descriptions, or non-compliant formatting before you send it to the Board.

Secure & Sustainable by Design

Built for the enterprise, aligned with the planet. We protect your sensitive data with industry-standard protection, encrypted infrastructure—while running on AI hardware that consumes 90% less energy than standard models.

Support for 100+ emissions and ESG disclosure standards—spanning emissions accounting, sector-specific disclosures, and global reporting frameworks.

The Trust Moat

Don't bring a generic chatbot to an audit.

Claritas ESG is designed for verification: curated source libraries, clause-level citations, and review-ready outputs. Your team moves faster because every claim is traceable—not because it's guessed.

Citation-Backed RAG

ChatGPT answers from the entire internet (including Reddit and Wikipedia). Claritas ESG answers only from the official texts like SB 253, SB 261, CSRD, TCFD and more. If the answer isn't in the law, we tell you—we don't make it up.

Standard AI Response:"Based on general knowledge, Scope 3 usually includes..."
Claritas ESG Response:"Per SB 253 Section 38532(c)(1), Scope 3 reporting begins in 2027..."

Total Model Freedom

Why pay for ChatGPT, Claude, and Gemini separately? Claritas ESG lets you pick the best model for the job.

Sustainable Compute

Using massive compute power to report on carbon reduction is an uncomfortable irony. Claritas ESG runs on specialized hardware (Groq/Cerebras) that cuts inference energy by ~90%—so your Scope 3 software doesn't blow up your Scope 2 targets.

Curated by Humans, Powered by AI

Our knowledge base isn't a web crawl. It is maintained by sustainability professionals who verify that regulatory updates (like the SB 261 injunction) are reflected in the system immediately.

What US teams do with Claritas ESG

Pick your reality. The product stays the same—citations, evidence, and documentation—but the win looks different depending on your seat.

Do the work of ten people.

The deadlines are real. The headcount isn't coming. Automate the archaeology so you can focus on strategy.

The Audit Shield

Scope 3 “Defensibility”

Don’t just calculate the numbers; document the why.

Keeper

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.

How do citations work?

Every answer is grounded in source documents and returned with paragraph-level citations. Reviewers can click through to the exact clause, page, and source—reducing verification time and strengthening evidence trails.

How is Claritas ESG different from ChatGPT, Gemini, or Copilot?

Three key differences: • Zero Hallucination Target: We use Grounded RAG on official texts, not the open web. Claritas ESG is built for verification: curated sources, traceable citations, and evidence-pack outputs structured for review. • Model Freedom: Don’t be locked in. Switch between models from OpenAI, Anthropic, Gemini and more to get the best AI for each task. • Sustainable Compute: We provide lower energy inference options (Groq/Cerebras), ensuring your AI use doesn’t inflate your emissions.

Do you replace our carbon accounting or ESG platform?

No. Claritas ESG sits on top of your existing systems. You still use your data warehouse, carbon tools, and spreadsheets to calculate numbers. Claritas ESG 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 ESG 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 ESG to review it against standards, and capture clarifications in one place. No months-long implementation needed.

What does "start free with 10 research credits" mean?

Create a workspace and get 10 AI-powered research actions to ask about standards, review disclosures, or draft methodology notes. Upgrade to paid plans in-product if helpful.
