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.

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.

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!

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.

I'm actually really impressed I'm actually really impressed with Wren. I'm a born skeptic and have been especially skeptical of anything related to ESG since it's so easy to exploit people's good intentions and poor training for personal gain, but Wren is a truly stand-out project that strikes the perfect balance of transparency and private development. (For example, they tell you all about the projects they're investing in, but the process of figuring out what the org should care about and how to support those ideals is less public (although probably not secret).) This provides you with all the information you might want without being noisy. Additionally, they're quite scientific in their assessment and selection of portfolio projects.This gives me a lot of confidence that my money is not just getting dumped into someone's Lambo. I've been with Wren for almost 2 years now and I can safely and emphatically say go for it.
