Blue carbon is the carbon stored, sequestered and released from coastal, estuarine or open ocean ecosystems and their closely related ecosystems.

Internationally, tropical forests have been the focus of initial carbon storage efforts. However, many countries and organisations such as the United Nations Environment Programme (UNEP) and the International Union for Conservation of Nature (IUCN) are now looking at the value of marine and coastal ecosystems including tidal marshes, mangroves and seagrasses.

This FRDC project looks at how revitalising Australia's estuaries will allow for great levels of carbon sequestration while also delivering further enivironmental and economic benefits.
