“New company but seems incredibly transparent and realistic. Looked into other carbon offsets and felt they were just doing lip service [...] Wren feels real, with obvious, researchable, meaningful offsets.”
Our goal is to make climate action simple & effective.
Protect rainforest in the Amazon
Wren members fund a project that works with indigenous peoples to protect their land, a natural carbon sink.
We search the globe for climate projects with the biggest potential.
All Wren projects meet three rigorous criteria:
Precise tracking
We carefully check how much CO₂ is offset by each project, so we can promise you lasting impact.
Regular updates
We get data straight from projects on the ground, so you can track your impact, month by month.

Our projects wouldn't happen without your support. With Wren, your money makes a real impact.
Then, we send you personalized updates every month.
Each update is filled with:
