Why UNDO?
Spoiler alert: because your phone consumes more CO2 than you think

Reality check incoming ...
If you use your smartphone every day, you emit an average of 60 kg CO₂ a year. That is about the same as the emissions caused by driving a car from Brussels to Amsterdam, and back. With UNDO you can compensate these emissions. We plant a tree for every new subscriber and you can support additional valuable projects, including several carbon removal technologies.

UNDO works closely with a village in Congo called IBI Village. In the adjacent grassland, we plant a tree for every new UNDO subscriber. You can also support various projects benefiting the people of IBI Village, ranging from medical aid to internet in the local school
