Welcome to COTAP’s Carbon Footprint Calculator

Our calculator is designed for individuals in the U.S. and focuses on car travel, air travel, and home energy use. To offset your CO2, use the Donate button in the Total section. Our calculator’s methodology can be found here.

Where Your Money Goes

Your tonnes will be evenly allocated to our projects and you will receive a detailed offset acknowledgement like this one. Your tonnes will be included in our public carbon credit retirements on the Markit Environmental Registry like this. You can track COTAP’s progress and download projects’ annual reports, which contain detailed accounting of payments to communities, in our Transparency section.
