Blue carbon: Generic name of carbon (inorganic, organic and living organisms) existing in the sea The amount of carbon deposited in small, shallow sea areas (accounting for only 1% of the entire

sea areas) accounts for more than 50% of the total amount accumulated all over the sea.

Blue carbon report issued by the United Nations Environment Programme (October 2009)

Unit: Tg C/year

Background of the study: What is “blue carbon”?

Deposited and accumulated carbon

The shallower the sea area is, the more the amount of carbon is deposited.The scope of worldwide discussions concerning blue carbon:

Unclear points:・ Undiscovered sea areas・ The “movement between the atmosphere and sea water.” Is CO2 in the atmosphere absorbed?
