Resetting our Climate Ambition

In 2024, City Council prioritized updating the city’s CAP to reflect the latest climate science, lessons learned, and community priorities.

Launching this spring, the updated CAP will energize forward progress and inspire another decade of collective climate action.
The undeniable reality is that climate change is not just happening — but also accelerating and intensifying. All ten of the hottest years on record have occurred since 2015, and one does not have to look far to see these catastrophic impacts play out in Boulder in real time — whether it was the 2013 floods or the 2020 Calwood or Marshall Fires.

Boulder’s Climate Action Plan (CAP) is the community’s roadmap for reducing carbon pollution, preparing for climate impacts, and investing in communities most affected by climate change.
