We remove carbon. Permanently.

Carbonsate was founded on a simple conviction: the most effective climate solutions are often the ones closest to nature. We build biomass storage projects that turn woody waste into permanent carbon removal – certified, monitored, and built to last centuries.

Our Goal

Remove more than 10 million tonnes of CO₂ from the atmosphere annually by 2033.

A field full of promises needs proof. We measure what we store, verify it independently, and publish the results - so our impact can be trusted, not just claimed.

What we stand for

Five principles, no exceptions.

01

Radical transparency

We say what we know, acknowledge what we don't, and never overstate our impact. In a field full of greenwashing, honesty is our sharpest tool.

02

Science first

Every claim we make is grounded in data. We operate our own measurement, reporting, and verification (MRV) systems, conduct ongoing field research, and hold ourselves to standards that go beyond certification requirements.

03

Real-world impact

Climate protection happens on the ground – with landowners, local communities, and regional partners. We build projects that create value beyond carbon.

04

Continuous improvement

We treat every project as a source of learning. Our ambition is not only to deploy biomass storage at scale, but to set the scientific and technical benchmark for the field.

05

Honest communication

We embrace direct, clear communication – with our partners, our buyers, and our critics. Every voice matters. No jargon. No spin.
