We have planted over 6.6 million trees since our foundin, and we are very proud! We realised that planting trees alone does not tackle all of the environmental issues we a passionate about, however. That's why we now also support projects that
- restore landscapes — ecosystems are repaired and jobs are created, including tree planting along the way
- remove carbon from the atmosphere and store it permanently
- recycle electronic waste and reuse materials
