PROJECT 2.9: Risk assessment of future carbon sources and sinks
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 don’t know how climate change will affect uptake and availability of nutrients and water, and how this will affect plant growth (and so potential to store carbon).
We’re developing models that we will use to assess the potential of revegetation and conservation activities in Australia to remove carbon from the atmosphere. We’re also looking 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. This work will 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.
This project supports Australia’s involvement in the Global Carbon Project.

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.
