Greenhouse gas stored in country’s marine world heritage sites about same as four years of emissions
Three of Australia’s world heritage-listed marine sites have more than 2bn tonnes of carbon dioxide locked away in their vast seagrass meadows, coastal mangroves and tidal marshes, according to a new report from a UN agency.
Unesco has for the first time calculated all the so-called “blue carbon” stored across its 50 world heritage marine sites and finds they contain about 5bn tonnes of CO2 and other greenhouse gases.
