California Climate Reporting Has Started
Under SB 253, U.S. companies with more than US$1 billion in revenue that do business in California must report their emissions, and that can include the U.S. subsidiaries of Canadian companies. The first Scope 1 and 2 reports are due November 10, 2026.

What’s the Difference Between Scope 1, 2 and 3 Emissions?
Scope 1 covers emissions from sources you own or control, like fuel burned in your boilers and vehicles. Scope 2 covers the electricity, heat and steam you buy. Scope 3 covers everything else in your value chain, from purchased goods to business travel, and it’s often the largest share of a company’s footprint.
Can You Start with Just Scope 1 and 2?
Yes. Scope 3 isn’t required for the first SB 253 reports due November 10, 2026, so many companies start with Scope 1 and 2. We build your inventory so Scope 3 can be added later using the same boundary and data.
Who Has to Report under California’s SB 253?
Companies formed under U.S. law, in any state, D.C. or federally, with more than US$1 billion in annual revenue that do business in California. Revenue is based on the lower of the last two fiscal years and is assessed company by company, so a Canadian business is covered through any U.S. subsidiary that meets the test. Nonprofits, insurers and government-owned companies are exempt. The first reports, covering Scope 1 and 2 emissions, are due November 10, 2026. Scope 3 isn’t required for 2026 reporting. For the November 2026 report only, companies can use emissions data they already had or were collecting by December 5, 2024, or file a statement on company letterhead if they had none.
What Do I Need to Get Started?
Tell us about your company, your locations and why you need the inventory. We’ll send a short questionnaire, agree the boundary and approach with you, and then let you know exactly which data to send.
