Clear insight where your money goes Clear insight where your money goes, even to what is used for advertisements. Nice updates and direct impact projects which they support!

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.

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 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.

Wren is about so much more than carbon offsets I've been supporting Wren for a few years now as a poor college student. They're transparent, impactful, and effective. Wren is about so much more than offsetting — it's also about lifestyle changes such as eating more plant-based foods instead of meat, replacing flying with other things, and talking about climate change with loved ones. I think Wren is very conscious of the limits of carbon offsetting. Even though that's their core business model, they are doing a lot of great educational work on social media to raise awareness for the importance of taking personal action on climate change. It's easy to write Wren off by saying that "carbon offsets are only a band-aid solution when systemic change is what's really needed," but some people seem to have that attitude almost as an excuse to avoid taking action. If you have the financial means to support Wren, most upper-middle-class people are morally obligated to do that in my view. That's only the beginning of what's needed to respond to the climate crisis, but you've got to start somewhere. As Wren's tagline says, "systemic change starts with you."
