PROJECT 2.9: Risk assessment of future carbon sources and sinks
This project ran from 1 July 2016 until 30 June 2019
Policy makers need information on carbon and greenhouse gases so they can develop successful national policies and international engagement to achieve climate mitigation targets. They also need robust evidence to help identify effective carbon mitigation options. Revegetation is a potentially low-cost option, but we have lacked data on how climate change will affect uptake and availability of nutrients and water, and how this will affect plant growth (and potential to store carbon).
We’ve developed models that we used to assess the potential of revegetation and conservation activities in Australia to remove carbon from the atmosphere. We have also looked at how vulnerable the mitigation potential is to climate change. This research will help determine the potential for land-based mitigation options in Australia, which will inform both Australia’s climate change and greenhouse gas policies, and growing carbon markets.
We have also produce national and global carbon budget data products that show how carbon dioxide and methane levels are tracking on the pathways needed for global climate stabilisation by the end of the 21st century.
In addition, we also supported Australia’s involvement in the Global Carbon Project.
Outcomes from this project will be used in the current Hub Project 5.6 – The carbon budget of continental Australia and possible future trajectories.
Key project achievements include:
- Added a land use change module to Australia’s national climate model, ACCESS, to better understand carbon sources and sinks in Australia
- Provided leadership and data to the Global Carbon Project – which provides information on emissions and carbon budgets to governments around the world
- Built relationships with Australian Government stakeholder, enabling us to better understand their information needs and to provide advice and information on carbon cycle related matters

This project is contributing to meeting the following climate challenge:
Research in this project will assess the potential of land-based carbon sequestration and its vulnerability under future climates. It will also track Australian and global carbon budgets. This work will monitor carbon budgets against agreed global targets, and support the Australian Government in achieving its mitigation targets.
