Welcome to COTAP’s Carbon Emissions Calculator

COTAP’s carbon emissions calculator is designed for individuals in the U.S. and focuses on car travel, air travel, and home energy use. To counteract your unavoidable contribution to climate change AND create income for the world’s poorest people, use the Donate button in the Total section. Our detailed calculator 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.
