Across the United States, cities, towns, and counties are enacting policies and programs to reduce greenhouse gas emissions. Many local governments are motivated by concerns about the impacts of climate change in their communities as well as an understanding that energy and climate solutions can benefit local economies and residents. Their actions reflect a strong history of local leadership in climate protection in the United States. While local governments face a number of limitations in addressing climate change, they can be a key part of the solution. Like states and regions, local governments can demonstrate leadership by implementing strategies to confront climate change and laying the groundwork for broader action at the national and international levels.
