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.

Wren carbon offsets deserve your trust Wren is probably the easiest, and more importantly, the most trustworthy carbon offset service available right now. Their programs are carefully vetted and audited, and they keep you extremely well informed of what your dollars are doing, without going overboard. You can’t go wrong with a subscription to Wren to offset your carbon footprint!

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.

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.

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!
