Number: RL33962 Title: Greenhouse Gas Reductions: California Action and the Regional Greenhouse Gas Initiative Authors: Jonathan L. Ramseur, Resources, Science, and Industry Division Abstract: California recently enacted several laws that seek to reduce greenhouse gas emissions. The first section of this report discusses the activity in California. The second section focuses on the Regional Greenhouse Gas Initiative (RGGI), a cooperative effort of eight states in the Northeast and Mid-Atlantic regions to reduce carbon dioxide emissions from power plants. The report's final section considers these state-led actions from a federal policymaking perspective, examining the potential effects, limitations, and legal challenges of state-led climate change actions.
