Streamline Your GhG Strategy:
Greenly transforms mandatory reporting:
a simple, 3-step workflow that turns raw data into an audit-ready report.
Measure Your SB 253 Emissions
- Calculate Scope 1, 2 and 3 from 500k+ emission factors, in a format your auditor can verify.
- Prepare 2027 Scope 3 reporting with EcoPilot and a dedicated expert, on a documented methodology.
- Connect EcoPilot to your ERP. It pulls your activity data and maps each line to an emission factor.

Assess Climate Risk for SB 261
- Map physical and transition risks under TCFD to satisfy SB 261 mandates effortlessly.
- Run your SB 261 risk analysis on the same data as your SB 253 inventory. One dataset, one audit trail.
- Leverage intuitive tools to run the climate scenario analysis SB 261 expects, no expert knowledge necessary.

Get assurance-ready, then file
- Catch weak points early with built-in guidance that strengthens your report before formal verification.
- Export your report in the format CARB's intake platform requires, ready to file.
- Reuse the same dataset for ISSB, GRI or SASB reporting. No second data collection.

SB 253 requires US companies with over $1 billion in annual revenue that do business in California to publicly report their Scope 1 and 2 emissions from 2026, and their Scope 3 emissions from 2027.
SB 261 requires US companies with over $500 million in annual revenue that do business in California to publish a climate-related financial risk report every two years, using TCFD or IFRS S2. Enforcement is paused: the Ninth Circuit enjoined SB 261 on November 18, 2025, pending appeal.
SB 253 Scope 1 and 2: first report due November 10, 2026, covering fiscal year 2025. Assurance is optional for this first report.
SB 253 Scope 3: starts in 2027, covering fiscal year 2026. Limited assurance on Scope 1 and 2 becomes mandatory the same year.
SB 261: first reports were due January 1, 2026. Enforcement is suspended while the Ninth Circuit injunction stands.
CARB can fine up to $500,000 per reporting year under SB 253 and up to $50,000 per year under SB 261. From 2027 to 2030, Scope 3 penalties apply only to failing to file, not to good-faith reporting errors.
For the first SB 253 report, CARB will not penalize incomplete data if the company shows a good-faith effort to comply. Greenly documents every calculation and data source, so your assurance provider and CARB can trace each figure back to its origin.
