Berkeley Law’s Center for Law, Energy & the Environment is among a group of organizations working with California regulatory officials to develop policies and recommendations for establishing a broad carbon market oversight and enforcement program. California is the only state with a climate-change law that mandates reductions in greenhouse gas emissions, and policymakers are pushing to ensure that state, regional, or federal cap-and-trade initiatives have maximum protection from fraud and manipulation. A new oversight and enforcement program may soon be included in California’s cap-and-trade proposal, and will likely help shape federal legislation and regulations.
