Blue Carbon Report

Cycling of carbon back into the biosphere is described as “green carbon” which is absorbed by land based organisms, and carbon absorbed by marine living organisms (55%) is called “blue carbon”. The Blue Carbon Report, produced by GRID-Arendal and UNEP, in collaboration with the UN Food and Agricultural Organisation, and UNESCO International and Oceanographic Commissions, was produced to highlight the vital role of the oceans and ocean ecosystems in the global climate balance.

The Report provides detailed and illustrated information on the importance and functioning of blue carbon capture and how this contributes to natural systems management of carbon. It explains clearly how the world’s oceans, seas and marine ecosystems (including seagrass, salt marshes and coastal wetlands) are daily absorbing and removing large quantities of carbon from the atmosphere.
