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 – 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.

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.

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.

This is the best way I’ve found to try… This is the best way I’ve found to try to do my part in this demanding world. We need initiatives like this one. The follow ups give me hope and their mission is beautiful. This is a wonderful and worthy effort.
