University of Maryland's Center for Global Sustainability releases tool, in partnership with America Is All In, that details U.S. city climate and energy policies

New York, NY (September 22, 2026) – The University of Maryland's Center for Global Sustainability (CGS) and America Is All In released the U.S. City Climate & Energy Policy Database today at America Is All In’s Local to Global Exchange. Detailing more than 1,400 climate and energy policies and programs enacted by 157 major U.S. cities across 48 states, the actions taken by cities improve health, reduce emissions, and increase energy efficiency and affordability across the buildings, transportation, and electricity sectors, among others. 

The database compiles policies cities have enacted, such as building codes, financial incentive programs, and procurement policies, to lower household energy bills, create jobs, and build resilience.

“This database gives us the clearest picture yet of how cities across the country are responding to the current moment with policy,” said Nate Hultman, Director of the Center for Global Sustainability at the University of Maryland. “What stands out is both the breadth of action and the opportunity it reveals: cities and states are pursuing clean energy and energy efficiency, and understanding that landscape is the first step toward accelerating action where it is needed most. The data show that local leadership is real, it is widespread, and it is providing the groundwork for a better pathway.”

“While the federal government has stepped back, this database shows how local leaders are building cleaner, healthier, more resilient communities in every corner of the United States,” said Chris Wheat, Executive Director of America Is All In. “America Is All In is proud to partner with CGS to show how city halls are making climate decisions every day.”

Examples from the database include:

  • Creating jobs and cutting costs: Cleveland is overhauling city facilities with renewable energy and efficiency upgrades; the city's plan to cut emissions 63.3% by 2030 is projected to save residents $2.3 million in energy costs and create more than 1,200 jobs per year.
  • Expanding clean, local energy: Boise operates the largest direct-use geothermal heating district utility in the United States, providing a renewable, emissions-free heat source to more than 95 buildings in downtown Boise, with plans to expand further.
  • Protecting residents from extreme heat: Phoenix Mayor Kate Gallego launched Shade Phoenix, a five-year initiative to expand the city's natural and built shade.
