I'm happy I've used this
By Gino C.
Love Wren! It makes it easy to understand your carbon footprint so you can work on reducing it and then its easy to offset the bit you can't reduce. Great service. Keep up the great work.
By Mr James M.
I just used the Wren App to figure my carbon footprint and then help offset it.... Easiest app I've ever used and so rewarding to know how to help mitigate what I do to harm the environment. Definitely going to try and figure out how to promote the good work of teaching and action that Wren is doing... Thanks Wren good work... Definitely worth supporting.

An easy user-friendly way to offset your carbon footprint
By Paul Y.
Great initiative, some minor issues with the calculator, but nothing to worry about, it'll be fixed promptly. Quick and easy to estimate carbon footprint and offset it.

Simple, crystal clear and efficient.

I reviewed about a dozen other carbon offset platforms out there, but none of the others gave me the level of transparency into the underlying projects as Wren. I’m a happy subscriber!
By Paul Y.
I love how simple Wren makes it to support Environmental projects, and how they have a great calculator to get a better sense of my monthly carbon output. They have also been sending out fantastic updates about the project I am helping fund, and it's wonderful to see how they've supported the farmers during COVID19 disruptions.
