Multi-state organizations and state and local governmental agencies are implementing their own global warming initiatives to reduce greenhouse gas emissions. For example, the Regional Greenhouse Gas Initiative (RGGI or "ReGGIe") is a cooperative effort among the states of Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New York, Rhode Island and Vermont under which the states have capped and will reduce carbon dioxide emissions from the power sector 10 percent by 2018. California has enacted a law requiring the state to reduce its greenhouse gas emissions to 1990 levels by 2020. The state has adopted numerous regulations to achieve that goal, most notably regulations to implement a cap-and-trade program, which was launched in 2012. The cap-and-trade program covers major sources of greenhouse gas emissions in the state, such as refineries, power plants, industrial facilities and transportation fuels. California has also implemented path-breaking regulations to limit carbon dioxide emissions from motor vehicles, which have served as a model for the federal government’s own regulations. Thirty four states and D.C. have adopted climate change action plans. These and other states and localities are taking measures to reduce greenhouse gas emissions and adapt to climate change.
