Remove CO2 permanently with carbonˣ

We help companies achieve their climate targets by securing high-quality permanent carbon removal credits.

Accelerating carbon removal.


It is undisputed that keeping the rise in global temperatures below 1.5°C will need an increased focus on carbon dioxide removal (CDR) — taking CO₂ out of the atmosphere and storing it permanently away.

We empower buyers to maximise their climate impact by securing access to future carbon credits and to actively participate in the growth of the carbon removal industry. 

CDR projects translate these commitments into funding and secured revenues for multiple years, enabling capacity expansion and meaningful growth in carbon capture & storage.
