Way more permanent than planting trees. It's not just planting trees, which can be cut down easily. It's something more permanent - mineral weathering or binding carbon in biochar. Those, who rely only on planting trees, look silly when compared to wren.

Wren explains what they're doing to combat global warming Wren pays organizations to reduce global warming. Naturally, donors want to know how their money is being used, and Wren is very transparent about that. A good amount of the money is spent on marketing but that's because Wren needs to get their story out to grow their system. And it seems to be working: their expenditures are increasing year by year.

Wren carbon offsets deserve your trust Wren is probably the easiest, and more importantly, the most trustworthy carbon offset service available right now. Their programs are carefully vetted and audited, and they keep you extremely well informed of what your dollars are doing, without going overboard. You can’t go wrong with a subscription to Wren to offset your carbon footprint!

Very satisfied with the service The service of Wren is highly transparent. They give an insight about the projects which are funded on a regular basis. In contrast to many other services who plant trees (which might be chopped down in a few years), Wren has several other concepts to save CO2.

Playing a Small Part in Wren’s Impact I appreciate the project updates that we receive regularly. Seeing how long-time initiatives are doing and finding out about new ones is lovely. I trust Wren and feel good about playing a small part in the impact they are making.
