Project Overview

The Climate Action Plan (CAP) Tax, which provides $1.8 million in funding for our community’s climate work is set to expire in March 2023.

To close this funding gap, the city is proposing a new Climate Tax that would combine and replace the CAP and Utility Occupation taxes. The new Climate Tax, as proposed, would raise $6.5M per year to fund city-level climate and resilience efforts. Like all taxes, the proposed climate tax would requires voter approval before going into effect.


CAP Tax Overview

The CAP Tax provides critical funding for our community’s climate work. It is a tax on electricity use and is collected on Xcel Energy bills. It generates about $1.8 million per year to fund some of the city's climate work.

CAP Tax Funding Supports Several City Climate Efforts

Since its inception in 2007, the CAP Tax has provided over $22M in critical funding for Boulder residents and businesses through efforts like:

  • Direct cash assistance to homeowners, landlords and businesses to fund energy efficiency upgrades.
  • Development of local solar energy projects.
  • Expansion of city transportation electrification projects and city-owned electric vehicle charging stations.
  • Regulation and building codes.
  • Policy and regulatory reform.
  • Partnership and international collaboration.

City of Boulder Climate Funding

There are two taxes currently collected that provide funding dedicated to the city’s climate efforts:

Climate Action Plan (CAP) Tax: A 2006 voter-approved tax on electricity consumption. This generates approximately $1.8 million per year and funds the city’s climate and energy efforts and will expire in March 2023.

  • Average Annual CAP Tax Rates
    • Residential Customers: $27 per household
    • Commercial Customers: $86 per customer
    • Industrial Customers: $128 per customer

Utility Occupation Tax (UOT): In 2020, voters approved an extension of the UOT through 2025 at a level of just over $2 million per year to fund the city’s partnership with Xcel Energy.

  • Average Annual UOT Tax Rates
    • Residential Customers: $16 per household
    • Commercial Customers: $155 per customer
    • Industrial Customers: $577 per customer

Community Feedback and Engagement

Community Survey Results

A graph that depicts responses to a May-June 2022 community survey conducted with 1180 Boulder residents over the age of 18. According to the results, 78% of respondents would vote yes; 19% would vote no. There is a city logo on this image.

In May and June 2022, the city conducted a statistically valid survey to collect feedback on the tax proposal.

Broadly, the results confirm that the community is deeply concerned about the climate crisis and is largely supportive of the city’s tax proposal.

Key findings include:

  • More than three-in-four respondents (78%) say they would vote yes on the city’s proposed climate tax.
  • Respondents are concerned about climate change and global warming. More than half of voters (58%) are “extremely worried,” while another 20% say they are “very worried.”
  • A plurality of respondents (36%) ranked “addressing the impacts of climate change” as the most important issue facing the city.

There were 1,180 responses to the survey from City of Boulder residents ages 18 and older. The survey was conducted online and via telephone May 19 through June 2 by polling firm Magellan Strategies. The poll has a margin of error of +/-2.83%. A summary of the results is available online.
