The city of Boulder, CO initiated a Climate Action Plan (CAP) tax in 2007. It is the nation’s first voter-approved tax dedicated to addressing climate change. The CAP tax is levied on city residents and businesses and is based on the amount of electricity they consume. Tax rates are different for each of three sectors: residential , commercial, and industrial. The CAP tax generates approximately $1.8 million each year.

In 2015, Boulder voters approved a continuation of the CAP tax through March 31, 2023

Unlike Boulder, the state of Colorado is trailing on carbon pricing, choosing to wait and watch actions in neighboring states (Utah).
