California Releases Platform for 2026 Emissions Reporting
The California Air Resources Board has released a new voluntary reporting platform, guidance document, and video tutorial to assist companies with their initial Scope 1 and 2 GHG emissions disclosures due November 10, 2026, under SB 253.
The California Air Resources Board (CARB) has issued new resources to help companies prepare for the first emissions reporting deadline under the state's climate disclosure law, SB 253. With inaugural reports on 2026 Scope 1 and Scope 2 greenhouse gas (GHG) emissions due by November 10, 2026, CARB has launched a voluntary online reporting platform, a formal guidance document, and a video tutorial explaining the submission process. While use of the platform is optional—companies may also submit reports via a dedicated email address—these tools provide needed clarity on the mechanics of compliance. The release demonstrates CARB's intent to adhere to the current timeline, even as the underlying regulations await final approval from the state's Office of Administrative Law. Covered entities should now be finalizing their GHG inventories and confirming internal processes for the November submission. The new guidance provides a clear pathway for the inaugural filing, representing a key milestone in the implementation of California's ambitious corporate climate transparency regime.
