“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.”
Wren members fund a project that works with indigenous peoples to protect their land, a natural carbon sink.
All Wren projects meet three rigorous criteria:
We carefully check how much CO₂ is offset by each project, so we can promise you lasting impact.
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.
Each update is filled with:
You don't have to imagine your impact. You can see it each month.
