CarboTax: Cutting-edge Calculator to Offset your Carbon Footprint

CarboTax is a web-based application that allows people to quickly understand how their climate impact compares to an easy-to-grasp benchmark – "the average American." The application is a nonprofit initiative of One Earth, Kensho.org, the non-profit arm of Kensho Technologies, and the Forest and Sea Fund, a project of Sustainable Markets Foundation. Its goal is to give people a way to offset their climate impact and in so doing, to send a message that it’s time to put a price on carbon dioxide emissions, the leading cause of climate change.

When you offset your climate impact through CarboTax you are paying a symbolic "voluntary tax." This tax-deductible donation is given to our charity partner the Forest & Sea Fund (FSF) directly supporting innovative forest and ocean conservation projects around the world. The recommended amount for your donation is based on your specific impact, measured in tonnes of carbon dioxide equivalent (CO2e) using a value of $25 per metric tonne.

Through FSF, a portion of all donations go directly to "paying it back" by offsetting the user's carbon impact through certified REDD+ credits provided by Natural Capital Partners. An equal amount of funds goes to "paying it forward" by supporting Blue Ventures marine conservation efforts. CarboTax was launched in partnership with National Geographic in support of the groundbreaking film on climate change, Before the Flood.
