Australia’s marine World Heritage Sites are among the world’s largest stores of carbon dioxide according to a new report from the United Nations, co-authored by an ECU marine science expert.

The UNESCO report found Australia’s six marine World Heritage Sites hold 40 per cent of the estimated 5 billion tons of carbon dioxide stored in mangrove, seagrass and tidal marsh ecosystems within UNESCO sites.

The report quantifies the enormous amounts of so-called blue carbon absorbed and stored by those ecosystems across the world’s 50 UNESCO marine World Heritage Sites. Despite covering less than 1 per cent of the world’s surface, blue carbon ecosystems are responsible for around half of the carbon dioxide absorbed by the world’s oceans while it is estimated they absorb carbon dioxide at a rate about 30 times faster than rainforests.
