Iｍpact1 site started・ Blue carbon now attracts attention as a new option for addressing global warming, and blue carbon initiatives are expanding around the world.・ At the Port of Tokyo, efforts are being made to create a bed of seaweed and seagrasses, such as wakame seaweed and eelgrass, making up a blue carbon ecosystem that acts as a CO2 sink and a habitat for various organisms and provides opportunities for environmental learning.・Tokyo PortCarbon inflow from terrestrial areasCarbon outflow to the open oceanAbsorption of CO2 from the atmosphereCarbon uptake through photosynthesisSeagrasses and seaweeds in shallow coastal watersCarbon burial in seabed sediments1615(Image for illustrative purposes)Objective of the TMG (planned)Installed in FY2024・Blue carbon ecosystems, such as seagrasses and seaweed, absorb the CO2 that is dissolved in seawater through photosynthesis and bury the carbon in ocean sediments (see the figure below). ・As a result, CO2 levels in the ocean decrease, and CO2 absorption is accelerated, which contribute to addressing global warming.the atmosphere from Contribution to SDGsRationale for the projectFY2024　*About blue carbonRealization of biodiversity・ The CO2 absorbed by marine ecosystems through photosynthesis and then stored in the ocean floor or deep ocean waters is called blue carbon.Installed 2 sites2 sites installedB l u e P r o j e ctDevelopment of a blue carbon* ecosystem at the Port of Tokyo
