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.

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.

Biobased building a way to double nature
Climate Cleanup | 21 Jan 2021
The benefits of biobased constructions are enormous. For people. For nature. For the climate.
People have evolved in nature, in the forests and in the fields. Wooden architecture brings nature back into our artificial built environment. We start to feel better: invigorated, healthier and with an increased sense of well-being. As we know, trees (more…)
