Wren – can't be more transparent Wren is a great way to really have a tangible positive impact on man-made climate change. You yourself can decide how much you want to spent – it even calculates how much you'd need to pay to offset your footprint entirely – and through the monthly updates that they provide you know exactly where your help is put into. I can only recommend it and it isn't even that expensive: I personally only pay 20€ per month to offset my entire CO₂ footprint and a little bit more. So when looking at our own and our kids future: This is not much to change the world for the better.

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.

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.

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 funding Climate positive projects Wren is funding Climate positive projects that are making difference. Projects I can relate to such as forest protection and natural carbon capture by tested methods. They are small but can be copied and so scaled up around the world. It is a way fo every individual to help with climate positive action that will make a difference over time. Please be part of the solution and contribute monthly
