This program explores Queensland’s Blue Carbon potential, including mapping of Blue Carbon stocks and sequestration rates. It aims to build QLD’s Blue Carbon future and expand carbon farming in QLD through the development of a new Blue Carbon market. To achieve this we have assembled a multi-sector R&D collaboration – comprising Academia, Project Developers, and Industry – which will examine opportunities for Blue Carbon additionality in the Great Barrier Reef catchment.
This includes doing an inventory of QLD Blue Carbon Stocks and sequestration rates, analyzing drivers of Blue Carbon sequestration in QLD catchments, creating spatial heatmaps of sites suitable for Blue Carbon additionality, and developing predictive models of Blue Carbon under different management scenarios.
This work is led by Deakin University’s Blue Carbon Lab. Project partners include the University of Queensland, James Cook University, CSIRO, GreenCollar Group, North Queensland Dry Tropics, Department of the Environment and Energy (International Blue Carbon Partnership), Qantas, HSBC, and the Great Barrier Reef Foundation.
This project is funded by the Queensland Government’s flagship Land Restoration Fund, with additional supporting contributions Deakin University.
This program began in May 2019 and is currently in progress. Predictive models of Blue Carbon for the Great Barrier Reef catchment are in construction.
Through a comprehensive, large-scale sampling campaign of sediment Blue Carbon in tidal marshes, mangroves, and seagrasses in a data-deficient region of temperate southeast Australia, this study contributed to the growing global inventory of blue carbon sinks.
This program sampled over 100 blue carbon ecosystems across the Victorian coastline (southeast Australia) to quantify total sediment stocks, variability across spatial scales, and estimate emissions associated with historical ecosystem loss. This study was among the first to present a comprehensive comparison of sediment stocks across and within coastal blue carbon ecosystems. We estimate substantial and valuable carbon stocks associated with these ecosystems that have suffered considerable losses in the past and need protection into the future to maintain their role as carbon sinks.

This ARC Linkage Project develops fundamental new knowledge of how Australia’s coastal ecosystems can be managed to achieve maximum carbon offset capacity into the future.
This research develops world-first decision tools that allow resource managers to predict how coastal management actions will affect the capacity of coastal ecosystems to sequester carbon and optimise their management for the most cost-effective blue carbon returns. This research is critical for the inclusion of coastal carbon into natural resource management and into the national greenhouse gas accounts providing new societal and financial impetus for restoration and protection.
Removal of atmospheric CO2 through biosequestration is necessary to keep global warming under 2°C as the world transitions to a low-carbon economy. Among the most efficient systems for biosequestration are vegetated coastal habitats – seagrasses, saltmarshes and mangroves – known as ‘blue carbon’ ecosystems. Australia holds one of the world’s largest stores of blue carbon worth billions of dollars. However, degradation of coastal ecosystems is dramatically weakening this capacity, resulting in the release of ancient stored blue carbon into the atmosphere, thereby accelerating climate change.
This work was led by Deakin University’s Blue Carbon Lab, involving partners from The Nature Conservancy, Parks Victoria, and Victoria’s Department of Environment, Land, Water, and Planing (DELWP).
This project was funded by an Australian Research Council (ARC) Linkage Grant.
This program was successfully completed in 2018.
