Blue Carbon Project
Of the 7.2 billion tons (average from 2000 to 2005) of carbon emitted into the atmosphere each year, 2.2 billion tons
are absorbed by the world’s oceans. This includes the amount absorbed by marine organisms (blue carbon), in
addition to the amount absorbed by seawater. The amount of CO2 captured by blue carbon is said to be 55% of the
900 million tons of CO2 annually captured on land by forests and other sources. (From the United Nations
Environment Program Report)
