Boulder is one of 119 cities to receive the top climate action score from the environmental impact non-profit.

Carbon Disclosure Project

The City of Boulder has been recognized by the Carbon Disclosure Project (CDP) as one of 119 cities across the globe taking bold leadership on environmental action and transparency.

CDP’s A List is designed to encourage and support cities to ramp up their climate action and ambition. A List cities build climate momentum, taking four times as many climate mitigation and adaptation measures as non-A Listers. Only 13% of 939 cities scored in 2023 received an A.

CDP, an international non-profit, reviews environmental data provided by local governments to evaluate how well cities are addressing the climate crisis while being transparent about their progress. To score an A, among other actions, a city must have a city-wide emissions inventory, a published climate action plan, a climate risk and vulnerability assessment and climate goals. Boulder reports its detailed emissions inventory and scientifically aligned targets, along with city plans and actions that address the climate crisis.

Boulder and the other 118 cities on this year’s A List, are also celebrated for showing that urgent and impactful climate action - from ambitious emissions reduction targets to building resilience against climate change - is achievable at a global level, and in cities with different climate realities and priorities.

“It is an honor to be recognized as an A List city by CDP for the fifth year in a row. Demonstrating action against our climate goals and sharing data about our progress is essential to build community awareness, gain trust and extend our efforts to address the climate crisis.”

- Jonathan Koehn, Director of Climate Initiatives

The city is committed to providing easily accessible and transparent data to the community. Boulder recently published its first Climate Action StoryMap, an interactive webpage that takes a holistic approach to assessing Boulder’s climate impact. The StoryMap builds on the city’s annual greenhouse gas inventory, exploring both the quantitative and qualitative impacts of local efforts to address the climate crisis. Additionally, the community’s 2022 greenhouse gas emissions data will be made available on Boulder Measures in the next few weeks.
