Who we are

Our story

Climate Cooperative was born from a shared concern about the future of our planet. We saw that many businesses wanted to reduce their carbon footprint but were held back by unclear, unreliable options.

The lack of transparency and verifiable results made it hard to take meaningful action. Determined to find a better way, we combined our expertise in sustainability and technology to create Climate Cooperative.

We wanted to offer a solution that not only helps the environment but also provides businesses with clear proof of their impact. By pinpointing the exact tree responsible for each kilogram of absorbed CO₂, we make carbon offsetting tangible and trustworthy.
