As Climate Mayors, we represent 330 cities with a combined total of over 64 million Americans. The geographies and populations of our cities are just as diverse as our own backgrounds, allowing us to bring a comprehensive set of perspectives and priorities to the table. Whether we come from the West Coast, Rocky Mountains, Great Plains, Midwest, South, or Northeast, we all share a common dedication to environmental preservation and climate action while maintaining the unique character of our cities and the prosperity our constituents.
