What is blue carbon?

Question

Accepted Answer

Blue carbon refers to the carbon that is captured and stored by the world's ocean and coastal ecosystems. These ecosystems include tidal marshes, mangrove forests, seagrass meadows, and sometimes even deep-sea sediments. These 'blue carbon' ecosystems are highly efficient at sequestering carbon from the atmosphere and oceans, acting as significant carbon sinks. They play a crucial role in mitigating climate change by removing and storing large amounts of atmospheric carbon dioxide.

Options B, C, and D describe other forms of carbon or carbon reservoirs: carbon in forest biomass and agricultural soils is often referred to as 'green carbon'; carbon contained in petroleum and natural gas refers to fossil carbon; and carbon present in the atmosphere is atmospheric carbon dioxide.

Therefore, blue carbon specifically refers to carbon captured by oceans and coastal ecosystems.
