If we are to keep global warming to 1.5 degrees, CO2 will need to be removed from the atmosphere.
The Ocean Nourishment Corporation is working to enhance the natural process of photosynthesis by phytoplankton whereby they draw CO2 from the atmosphere.
As more CO2 is drawn down, more carbon will be stored at the bottom of the ocean when the phytoplankton die.
A carbon credit can be created for each additional tonne of CO2 stored.
If 2.4 billion tonnes can be stored, then, at $50 per tonne, this technique can create a market in excess of $100 billion.
