What is CA SB253
SB 253 is also known as the California Climate Corporate Data Accountability Act.
California’s SB 253 requires large companies (over $1B in revenue doing business in California) to report:
- Scope 1: Direct emissions
- Scope 2: Purchased energy
- Scope 3: Emissions across their full value chain —including suppliers and service providers
Scope 1 and 2 reporting is already underway.
First Scope 3 (supply chain) reporting will be based on 2026 data, disclosed in 2027.
Why This Matters
Most companies are focused on their own reporting requirements.
But the biggest impact will be felt across their supply chain.
If you work with these companies, you will likely be asked for emissions data.
Often:
- With little notice
- Without clear guidance
- Before you’re fully prepared
Important Distinction
SB 253 reporting is based on carbon emissions—not usage.
That means:
- It’s not just utility usage
- It requires translating operations into emissions data
- Most teams are not set up for this today
Who This Applies To:
Companies Required to Report
Large companies (over $1B in revenue) doing business in California.
Companies in Their Value Chain
Suppliers, service providers, and partners whose data will be required for Scope 3 reporting.
Including:
Suppliers / Manufacturers
Your customers will begin requesting emissions data.
Service Providers
Architects, Engineers, IT, and other consultants: Even without manufacturing, your operations contribute to client Scope 3 emissions.
What Most Companies Get Wrong
- Waiting until requests come in
- Assuming this only applies to large companies
- Not capturing data during normal operations
What to do Now
- Start capturing operational data
- Understand where emissions come from
- Prepare before requests begin
