Many states have completed comprehensive Climate Action Plans, or are in the process of revising or developing one. The plans detail steps that the states can take to reduce their contribution to climate change. The process of developing a climate action plan can identify cost-effective opportunities to reduce emissions that are relevant to the state. The individual characteristics of each state’s economy, resource base, and political structure provide different opportunities for dealing with climate change. However, without targets for emissions reductions, incentives for cleaner technologies, or other clear policies, climate action plans will not achieve real reductions in GHG emissions.
