Quality Company, tells me what there spending my money on, unlike my own goverment
By mike L.
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.

I felt that their CO2 calculator was thorough, and helped me on points where I did not really understand how to answer. Their projects appear to be well thought through, and you can choose what your money go to.

They are so honest and considerate! Customer service is amazing. Makes helping our climate as easy as it needs to be!

super easy sign-up & setup. regular updates via Email. glad to be able to compensate my personal emissions, thanks wren-team :-)

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 doing an excellent job. Sometimes planting trees works very well and sometimes it doesn't, so very good to find a Carbon offset organization that uses other ways to offset Carbon emissions. Especially like their program to provide Clean Cooking Fuel for Refugees, humanitarian and good for the environment, what could be better?

They are walking the talk Investing and reporting on where they are investing, and reporting on how well the invested projects are working to solve climate change (i.e., latest update: Biochar)
