Boulder's Climate Action Plan

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

The updated Climate Action Plan is more than a policy document. It is a shared commitment to reduce climate change, prepare for what is already changing and invest in a healthier, more resilient future.
