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.

Wren is about so much more than carbon offsets I've been supporting Wren for a few years now as a poor college student. They're transparent, impactful, and effective. Wren is about so much more than offsetting — it's also about lifestyle changes such as eating more plant-based foods instead of meat, replacing flying with other things, and talking about climate change with loved ones. I think Wren is very conscious of the limits of carbon offsetting. Even though that's their core business model, they are doing a lot of great educational work on social media to raise awareness for the importance of taking personal action on climate change. It's easy to write Wren off by saying that "carbon offsets are only a band-aid solution when systemic change is what's really needed," but some people seem to have that attitude almost as an excuse to avoid taking action. If you have the financial means to support Wren, most upper-middle-class people are morally obligated to do that in my view. That's only the beginning of what's needed to respond to the climate crisis, but you've got to start somewhere. As Wren's tagline says, "systemic change starts with you."

Wren is making a difference in big, important ways! I have supported Wren for some time now, and am impressed by the many projects they have brought on line to reduce emissions, transition to renewable resources. Recently I asked to switch my contribution to their tax deductible program, and the response to my request was prompt, personal and efficient. If you wish to be part of addressing climate change in productive ways, I recommend you check out 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.

Wren is awesome Wren is awesome! Made me realize it's actually not that expensive to live carbon neutral. When I first joined as a student living in a studio a few years ago I was able to offset all my CO2 for less than the cost of my Netflix subscription. The cost of offset has increased a bit, but I decided to stick with my original annual amount. They never increase costs unless you choose to!
