What is blue carbon? It's a term used to describe the carbon that is captured from the atmosphere by ocean ecosystems, mainly coastal mangroves, seagrasses and salt marshes. These coastal areas can hold up to five times more carbon than tropical forests, which means they play an important role in both removing excess carbon from the atmosphere and storing that carbon for the long haul. Destruction of these ecosystems releases the stored carbon, in addition to removing important wave protection and fish nursery grounds.
