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 natural climate solutions in actual projects and we foster the fundamental conditions for entrepreneurial people to flourish in the new nature economy.
What we do

Double Nature


Fostering fundamental conditions

We foster the fundamental conditions for the 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.

What we do



We do. Innovation needs experiment, therefore we pioneer solutions, particularly in seaweed and rock weathering. We develop this up to proof concept, so markets can take up what we start and grow in a distributed way.

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

Carbon removal accounting


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.

Let regeneration fly
Climate Cleanup | 26 Apr 2021
Not one single group can regenerate the planet on its own; we need to break down silos and collaborate across all kinds of networks to really reverse global warming this decade. How to organize this? How to connect self-organized swarms of people all around the globe? Could this connection create the conditions for climate action to emerge by itself? This will be the topic of our Double Nature Talk Wednesday April 28, 8 pm CEST, by Tijn Tjoelker. Tijn, a young Dutch regenerator connected to the 1500 club of Climate Cleanup (more…)
