Across the country, states and regions are adopting policies to address climate change. These actions include increasing renewable energy generation, selling agricultural carbon sequestration credits, and encouraging energy efficiency. Such policies reduce vulnerability to energy price spikes, promote state economic development, and improve local air quality. Addressing climate change will require comprehensive national policy and international agreements. However, in the absence of federal policy, states and regions are taking the lead on developing policies that may provide models for future national efforts.
