The systemic advantages of seaweed cultivation are overwhelming. Seaweed offers food, feed for animals, feedstock for the biobased economy and for energy. It does not compete for fresh water or for agricultural land (no kidding!), and in general it increases biodiversity – other sealife – in places where it grows. Almost as a bonus, it sequesters CO2 about five times as fast as trees and land plants. A truly multi-potent climate solution.

With about 9% of the oceans under cultivation, we can remove all of the excess carbon in our atmosphere, restoring pre-industrial levels (N’Yeurt et al 2012). Seaweed captures CO 2 this quickly because it grows fast (~ 5x as fast as land plants).

Join The 1500 Club

With 1500 people we aim to remove the 1500 gigaton of extra CO2 in our atmosphere, using nature based solutions. This 1500 Club is by and for parents, entrepreneurs, investors, youth, decision makers and anyone who wants to suck CO2 with us. Take part in our plan to draw 1500 gigaton CO2 out of the atmosphere as soon as possible and restore ecosystems and the global carbon balance.
