For the second consecutive year, Colorado has been named an environmental leader, with the state snagging the prestigious "A-list" status from CDP, a global non-profit that runs the world's independent environmental disclosure system. According to the Colorado Governor's Office, Colorado was one of just two states to earn this distinction, out of the 91 states and regions that disclosed their data in 2025. Colorado's capital city, Denver, and others like Aspen, Fort Collins, and Lakewood also received A-list accolades, marking them as cities taking leading strides in environmental reporting and climate action.
Colorado Governor Polis took pride in the state's achievement, "Colorado is proud to be leading in data-driven approaches to combat the impact of climate change, save Coloradans money, and protect our natural resources. Data helps Colorado to make informed decisions to help save people money and maximize environmental, economic, and health benefits in our communities. We appreciate CDP’s recognition and look forward to demonstrating the ongoing benefits of our climate work,” he said, as per the Colorado Governor's Office, in a statement that underscores how critical the state views its efforts in climate progression. This focus on actionable science and data has not only vaulted the state into a leadership position but has shown a commitment to transparency and efficacy that other states might well envy or emulate.
The recognition by CDP is based on stringent criteria: regions and local governments must have an up-to-date emissions inventory, climate risk and vulnerability assessment, and an actively implemented climate action plan. It's not just about planning, however, as A-list recipients also commit to working toward net-zero greenhouse gas emissions by 2050 or sooner and diligently track progress to ensure these targets are met. Colorado has shone in these areas, demonstrating that diligent, systemic action can align with broader environmental and health goals.
Jill Hunsaker Ryan, the executive director of CDPHE, highlighted the significance of the work done, “This recognition shows what’s possible when Colorado leads with science, transparency, and action,” she told the Colorado Governor's Office. Stating that “Strong data helps us set targets, implement emission reduction strategies, and measure progress. Lower emissions protect communities, improving health and reducing costly health impacts. We’re proud to be one of only two states in the nation earning this top distinction.”
