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.

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.

A great way to start living more aware life A great way to start living more environment friendly way not only by paying up for the pollution we generate but also staying informed of what's changing and getting involved more and more into the movement to help protect the planet.

No better way to reduce your carbon footprint I can't find a better way to reduce my carbon footprint more conveniently than paying Wren to offset it for me. I do want to make changes myself as an individual but the impact of that is limited. However, it's not nothing and Wren suggests those changes as well.

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.
