20 governors, including Governors O’Malley and Kaine, signed the Governor’s Declaration on Climate Change at the 2008 Conference on Climate Change held at Yale University. The declaration states that first, a federal-state partnership is critical to success on climate change action; second, state-based actions have paved the frontier of climate change policies; and third, mandatory state and federal action should be rewarded and encouraged. The governors pledged to work with the next president to shape federal action on climate change, taking the lessons learned from actions in their states into account. Governors from Arizona, California, Colorado, Connecticut, Delaware, Florida, Illinois, Iowa, Kansas, Maryland, Maine, Massachusetts, Michigan, Minnesota, New York, New Mexico, Oregon, Vermont, Virginia and Washington all signed the pledge.
