Safe and Permanent
Carboniferous is working to safely accelerate
one of Earth’s most powerful natural climate recovery processes
by sequestering terrestrial biomass in anoxic marine basins.
Why agricultural byproducts?
Crops absorb gigatons of CO each year, mostly to grow stalks and leaves. In most of the U.S., a third or more of these 'byproducts' can be sustainably removed from fields. This enormous mass of organic carbon can be transported via a vast existing infrastructure that is prepared to operate at climatically-meaningful scales.
Why anoxic basins?
Anoxic basins contain no dissolved O2, so they are inhospitable to all eukaryotic life (animals, plants, protists, and more). This means that biomass sequestration in anoxic basins avoids potential impacts on these seafloor communities. In the absence of these organisms, nearly all (>90%) of the carbon deposited in anoxic basins can be preserved for thousands of years or more.

Shipwrecks in the deep, anoxic Black Sea have stored their carbon for ~3000 years.
