On July 7, the California Air Resources Board released proposed changes to the state's planned emissions trading program aimed at clarifying issues involving allowances, market oversight, enforcement, and offsets. CARB is also recommending that certain elements of the trading program begin in January 2012 as planned, but that compliance obligations begin one year later that originally proposed. CARB sought to bring its mandatory GHG emissions reporting into alignment with with the Environmental Protection Agency's greenhouse gas reporting regulation as well as the proposed changes to the state's trading program rules. CARB has scheduled a July 15 workshop in Sacramento to discuss the proposed revisions, and a formal public comment and review period will follow later this summer.
