The California Air Resources Board plans to address the potential effects of waste-to-energy operations and combined heat and power facilities on greenhouse gas emissions by making a new round of revisions to the state’s cap and trade program. The board adopted a resolution September 20 calling for staff to review the program’s trading rules governing electricity importers and to continue evaluating the risks posed by cap and trade rules to trade exposed industries. The resolution also calls for staff to return to the governing board in October to address the program’s resource shuffling issue. The program applies to 360 businesses, representing 600 facilities.
