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.

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.

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.

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 is exactly the platform I was looking for! Wren is exactly the platform I was looking for. I've been looking for a platform that allows me to donate to activities that mitigate greenhouse gas emissions over a broad category of projects (including lobbying, carbon capture, nature protection, emissions reductions, etc). You can track where you money goes. You can easily modify your donation amounts and focus. The only downside is the relatively large fraction of donations they keep for their operations. I guess this is the price to pay for a great web interface and all the research and coordination required to find new projects.
