The City of Boulder is the only municipality in North America to have adopted a local carbon tax. The tax is collected from residential, commercial, and institutional customers of Xcel Energy, the local gas and electricity utility. Only customers who chose to purchase electricity from renewable sources (at a premium price) are exempt from the carbon tax. Revenues are used to fund various energy-efficiency initiatives that are being implemented under the City's Climate Action Plan (CAP).
