Description
The CARB Board adopted amendments to the Regulation for the Mandatory Reporting of Greenhouse Gas Emissions via Resolution 26-6 at its May 28, 2026 meeting. The amendments include clarifications on cessation, emissions and product data reporting requirements, and definitions to support accurate and complete GHG accounting and the Cap-and-Invest Program. The amendments also address potential emissions leakage from imported electricity transfers within CAISO's Western Energy Imbalance Market, including anticipated Extended Day Ahead Market transactions. These changes harmonize MRR reporting with the Cap-and-Invest and Low Carbon Fuel Standard programs.
