California SB 253, the Climate Corporate Data Accountability Act, requires companies with over $1 billion in annual revenue doing business in California to disclose their Scope 1, 2, and 3 greenhouse gas emissions. For Ontario manufacturers, this matters — even if you're not based in California.
Why This Affects You
If any of your customers are Fortune 500 companies operating in California, they are required to report their Scope 3 emissions — which includes emissions from their supply chain. That means they need data from you.
Key Deadlines
Scope 1 and 2 emissions reporting begins in 2026 for fiscal year 2025 data. Scope 3 reporting begins in 2027 for fiscal year 2026 data. Companies that fail to comply face penalties of up to $500,000 per year.
What You Need to Do
Start by calculating your Scope 1 and 2 emissions using the GHG Protocol methodology. This gives you the baseline data your customers will request. Then prepare a simple summary document you can share when customers send ESG questionnaires.
