Maximising the impact of voluntary carbon action.
Through infrastructure, data and collaboration.

In its current form, the voluntary carbon market will not reach its required gigaton GHG mitigation potential. Direct trade, relentless transparency, and higher quality will help drive the necessary change.

This is what we are working for.
CEEZER team

We build the digital infrastructure to transform voluntary climate investment into highest-impact climate action.

Team

We are a team of business, tech/product and climate experts with a strong background in natural sciences. We embrace working in an insanely dedicated team, as diverse as our home, Berlin. Yet, we are united in our determination to combat climate change.

Culture

We believe in strong ecosystems, for and beyond our concrete climate mission. This holds true from project developers to buyers, from partners in the value chain to the scientific community. And - most importantly - for our own team. We foster close relationships and direct, eye-level collaboration to make our product, ourselves, and ultimately the entire climate community more powerful.

Driven by change.
Bound by convictions.
