Out of all the biological carbon (or green carbon) captured in the world, over half (55%) is captured by marine living organisms – not on land – hence it is called blue carbon. Continually increasing carbon dioxide (CO2) and other greenhouse gas emissions are contributing to climate change. Many countries, including those going through periods of rapid growth, are increasing their emissions of brown and black carbon (such as CO2 and soot) as a result of rapid economic development. Along with increased emissions, natural ecosystems are being degraded, reducing their ability to absorb CO2. This loss of capacity is equivalent to one to two times that of the annual emissions from the entire global transport sector.
