Abstract

Policies aiming to preserve vegetated coastal ecosystems (VCE; tidal marshes, mangroves and seagrasses) to mitigate greenhouse gas emissions require national assessments of blue carbon resources. Here, we present organic carbon (C) storage in VCE across Australian climate regions and estimate potential annual CO2 emission benefits of VCE conservation and restoration. Australia contributes 511% of the C stored in VCE globally (70185 Tg C in aboveground biomass, and 1,0551,540 Tg C in the upper 1 m of soils). Potential CO2 emissions from current VCE losses are estimated at 2.13.1 Tg CO2-e yr-1, increasing annual CO2 emissions from land use change in Australia by 1221%. This assessment, the most comprehensive for any nation to-date, demonstrates the potential of conservation and restoration of VCE to underpin national policy development for reducing greenhouse gas emissions.
