Coastal forests

take in greenhouse gases up to four times

faster than land forests.

What is Blue Carbon ?

Blue carbon is the carbon captured by ocean and coastal ecosystems. Mangroves, tidal marshes, and seagrass meadows store this carbon as biomass or in sediments.

Why is it important?

When protected or restored, blue carbon ecosystems sequester and store carbon.Blue carbon is the carbon dioxide captured by the world’s ocean and coastal ecosystems. This carbon is stored in the form of biomass and sediments from mangroves, tidal marshes and seagrass meadows
