With technical and policy advice from WRI, three mandatory regional carbon trading markets are being established to limit states' greenhouse gas emissions, spur energy innovation and create green jobs. Twenty-three U.S. states are taking part, covering over half the U.S. population. Seven more states are formal observers. In September 2008, the Northeast and Mid-Atlantic Regional Greenhouse Gas Initiative (RGGI) began formal carbon trading. The Western Climate Initiative and the Midwestern Greenhouse Gas Reduction Accord are in development and will be operational by 2012.
