City of Phoenix Achieves Prestigious CDP ‘A’ Score for Environmental Leadership

City of Phoenix has been recognized by CDP, the global environmental non-profit, for its leadership in transparency and action, securing a place on CDP’s respected annual ‘A’ List. CDP operates the world’s only independent environmental disclosure system, with over 1,000 cities, states, and regions reporting environmental data through CDP in 2025.

Achieving an ‘A’ places the City of Phoenix among 120 cities receiving top scores on climate action by demonstrating comprehensive disclosure, mature environmental governance, and meaningful progress towards environmental resilience. The City of Phoenix has been on the ‘A’ List for the past four years.

The full list of cities on the 2025 CDP A List, and the full methodology and criteria, is available online.

To achieve an A score, a city must meet a series of robust leadership criteria. This includes publicly disclosing environmental data through the CDP-ICLEI Track platform, maintaining a comprehensive city-wide emissions inventory, and publishing a credible climate action plan. Cities must also complete a full climate risk and vulnerability assessment and set a clear climate adaptation goal that outlines how they will address current and future climate hazards.

"Phoenix's approach to building a more resilient city is ambitious, transparent and data-driven and we are thrilled that CDP has recognized our efforts four years in a row with their coveted “A” rating,” Phoenix Mayor Kate Gallego said. “As a desert city built on innovation, Phoenix continues to develop new solutions for water conservation, heat mitigation, and clean tech for the benefit of our residents. We hope our unique context provides a model from which communities around the world can learn." 

CDP recognizes that cities play a decisive role in shaping a resilient and earth-positive future. Robust climate planning and clear adaptation strategies, not only protect their communities but also unlock opportunities for innovation and sustainable growth. City leadership shows how data-driven climate action can strengthen both people and the planet.
