We are people reversing climate change. We remove carbon dioxide from oceans and the atmosphere. We double nature by fostering fundamental conditions for the regenerative economy.

We remove 1500 gigaton of CO2

To contain the climate crisis we need to remove 1500 gigaton of CO2. This happens to be about what is already stored by all plants and trees on earth. So to remove 1500 gigaton, we need to double nature. We reverse climate change by developing Nature-based Solutions and we foster fundamental systemic conditions for entrepreneurial people to flourish in the regenerative economy.
What we do

Double Nature

Fostering fundamental conditions

We foster the fundamental conditions for the regenerative new nature economy. Natural Climate Solutions can provide over 30% of the solution to reverse climate change, but receive not even 3% of funding. We are closing this gap by creating the conditions for entrepeneurial people and organisations to flourish.

We do. RD&D are much needed for natural carbon removal, because potential is huge and largely untapped. We develop in practice as well as in our Natural Climate Solutions Lab. 

Ocean | Land | Rock


We foster the fundamental conditions for people to thrive in the new nature economy.

We show the world what we want. We envision how beautiful the world will be in a new nature economy. We’re always fact-based: we show what can be done. And then we do.

We have a new paper out on marine silicate weathering in sediments from the #Mariana Trench.

Thanks for involving me in this super interesting work, Min Luo (noT).

Silicate weathering happens everywhere, from the continental shelves to the #deep sea🌊🌏

Happy #MangrovesDay!

Mangroves act as boundaries between land & sea 🌊 that provide protection & food security to many coastal communities. However, they are disappearing 3-4 times faster than forests!

Here is how to save these biodiverse ecosystems ⤵️

Happy to present the Dutch translation of Regeneration. Order your copy here: 🌱🌱
