Last year, the Regional Greenhouse Gas Initiative (RGGI) made news when seven states: Maine, New Hampshire, Vermont, New York, Connecticut, New Jersey, and Delaware banded together to cap carbon emissions in their states through a cap-and-trade program. Shortly thereafter, three more states, Massachusetts, Pennsylvania, and Maryland, joined as limited partners. Today, the Associated Press reports that ten states, some of which are members of the RGGI, are suing the EPA to force a cap on greenhouse gases under the Clean Air Act. Those states are New York, California, Maine, Massachusetts, New Mexico, Oregon, Rhode Island, Vermont, and Wisconsin. It is certainly not news that the US is not a party to the Kyoto Protocol, but these two actions by groups of individual states may well prove the strength of a Republic. If regional action succeeds, inaction on climate change may die the death of 1000 cuts.
