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 in scalable seaweed, olivine and agroforestry solutions. 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.
