Transparency and a commitment to tackling the climate crisis, even when it means working collaboratively with competitors! What's not to love?
Wren’s work to reduce harmful human impacts on our beautiful planet are strategic and thoughtful. I also love that the impacts are measurable. I highly recommend the team at Wren.
I’ve been donating for numerous years, and my initial worry was how trustworthy the company was. With monthly updates and articles to boot, that worry is put at ease. Added to that is the ability to change/ cancel your plan at any time. In terms of the website, access to a number of different functions. And well worth the amount you donate, due to the constant reminder of bad being done, and giving a little something back to rectify that.
Honest, genuine and making a difference.
Happy to contribute to this valuable international organisation doing great work in many and varied projects
Transparent reporting, strong principles, access to the founders, and decent analytics are some of the main reasons I choose Wren for my personal carbon offsets. They make it easy and fun to have net zero carbon footprint. It feels good.
Thank you for the kind words, Aubrey! We're glad to have you as a member.
Wren is the best service for turning dollars into climate results. They are hyper transparent and are constantly reporting out their efforts and success. I trust them to make the most impact per dollar of anyone out there. If you care about saving the planet, Wren is the place to do it.
Thank you Evgeny! This means a lot. We're so glad you appreciate the work we put into our reporting updates.
It might not be much, but knowing that I am doing even a little bit to help fight the climate challenge is very heartening.
A great way to start living more environment friendly way not only by paying up for the pollution we generate but also staying informed of what's changing and getting involved more and more into the movement to help protect the planet.
I appreciate the project updates that we receive regularly. Seeing how long-time initiatives are doing and finding out about new ones is lovely. I trust Wren and feel good about playing a small part in the impact they are making.
They do good thing. Feel thrustworthy, open and approachable via mail/discord.
Too often, climate discussions turn into comparisons of various state-imposed solutions, usually punitive taxes, stifling regulation, or both. Being both climate-conscious and a staunch supporter of free-market solutions, Wren has given me a way to do my bit toward solving the climate crisis without merely handing more power to governments. Their offsets allow me to directly fund climate solutions, while giving me an incentive to reduce my footprint in a way that fits my life and values (and suggestions on how to go about it!). This puts power back into the hands of individuals, and shows that we can solve global problems with voluntary solutions. So subscribe to Wren, and be part of a freer, cleaner, better world!
Wren gives very open communication of what they are doing.
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 has a pragmatic approach and I like it a lot. I also love their transparency and communication with their customers.
Clear insight where your money goes, even to what is used for advertisements. Nice updates and direct impact projects which they support!
I can't find a better way to reduce my carbon footprint more conveniently than paying Wren to offset it for me. I do want to make changes myself as an individual but the impact of that is limited. However, it's not nothing and Wren suggests those changes as well.
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 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.
