The California Air Resources Board announced a set of early measures to help bring the state closer to reducing greenhouse gas emissions to 1990 levels by 2020, as required by California law under AB 32. The new regulations will go into effect in 2010 and will affect the trucking, cement, aluminum, and semiconductor industries as well as ports, consumer aerosol products, and tire inflation requirements. These measures are expected to reduce emissions about 3 million metric tons annually. The board also accepted rules developed by the California Climate Action Registry to standardize the methodology used by nonprofit groups to quantify the carbon credit granted for growing trees or changing management practices. Rules for state, corporate, or private forest practices are not yet developed.
