Restoring our oceans' natural capacity to permanently remove CO2.
Worldwide.

Pronoe is a CO2 removal company.
We restore the ocean’s natural ability to capture and permanently store CO2 from the air, in a sustainable, scalable and asset-light manner.
In practice, we design and deploy automated water treatment systems that seamlessly integrate downstream of the operations of coastal industrial sites.
As a result, Pronoe’s activities generate high-quality CO2 removal certificates to customers, valorize otherwise wasted effluents, and locally mitigate ocean acidification.
To the benefit of the climate, coastal communities and ecosystems, worldwide.
