Wren is a much needed project Wren is a much needed project. It makes carbon offseting an easy, fun and scalable process. Great UI as well as clear communication. Two features I admire: 1. Groups: It's an innovative use case and has great potential for friends, families and team members (companies, orgs, etc..) 2. Carbon API. Building automations around offseting is quite an interesting platform for building an endless amount of use cases. I'm eager to test it out!

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.

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.

I love knowing I am doing something to help It might not be much, but knowing that I am doing even a little bit to help fight the climate challenge is very heartening.
