We reverse climate change by re-storing carbon. We aim to sequester 1500 gigaton of CO2 which is the same amount that is already taken up by life on earth - we Double Nature. At the core of our strategy is innovative entrepreneurship in ocean, land, rock and construction based carbon dioxide removal (Nb-CDR).Will you join?
