The fifth ACEEE City Clean Energy Scorecard measures the progress of city policies and programs that save energy, encourage renewable energy, and reduce greenhouse gas emissions while also focusing on equity in development and delivery. We rank 100 large U.S. cities for their energy efficiency and renewable energy efforts across 5 policy areas: local government operations, community-wide initiatives, buildings, energy and water utilities, and transportation. In this year's results, New York earns the top spot in the rankings for the first time. Joining New York at the top are Boston and Seattle (tied for second) and Minneapolis and San Francisco (tied for fourth). St. Paul and St. Louis are the most-improved since the 2019 City Scorecard. Overall, we found that many cities continue to ramp up their clean energy efforts, but bottom-scoring cities are years behind the policy efforts of the leaders. The Scorecard provides a roadmap for cities aiming to take the next step in their pursuit of clean energy by learning from others’ successes and adapting best practices to suit their own communities.
