[JURIST] Nine northeastern US states are working on a plan to cap and then reduce the level of greenhouse gas emissions from power facilities, an agreement which would see the states breaking with President Bush, who earlier this summer rejected [JURIST report] the Kyoto Protocol [text] on climate change. Each state legislature in New York, New Jersey, Connecticut, Delaware, Maine, Massachusetts, New Hampshire, Rhode Island and Vermont would have to approve the cap for carbon dioxide emissions, set at 150 million tons a year. Beginning in 2015, the cap would be lowered, and emissions would be slashed by 10 percent in 2020. California, Washington and Oregon are considering a similar agreement. Reuters has more.
