When compared to the total annual greenhouse gas emissions
in CO2 equivalents as reported by the UNFCCC Greenhouse Gas Inventory Data for the last inventory year excluding land-use changes (http://unfccc.int/ghg_data/items/3800.php), one observes that the Mediterranean Sea is overall responsible for sequestrating 0.7% of the total yearly emissions of the neighboring countries. On a country-by-country basis, such value is highest for Malta (10.1%), Tunisia (3.9%), and Algeria (3.4%). Marine biological processes are responsible for the sequestration of 10.5% and 5.8% of the total emissions of Malta and Cyprus, respectively.
