Woodside Pluto Carbon Offset Project - Stage 2

Woodside Pluto Carbon Offset Project - Stage 2 is a permanent mallee planting project located across two distinct regions: the Parkes Shire, roughly 350km west of Sydney in NSW, and the Shire of Jerramungup in Western Australia. It was registered in June 2014. The exact project area size is partially suppressed under section 169 of the Carbon Credits (Carbon Farming Initiative) Act 2011.

Mallee planting projects involve establishing permanent plantings of native mallee eucalypt species on land that was predominantly used for agricultural purposes for at least five years prior to project commencement. The methodology requires plantings to be established at sufficient stocking densities to achieve permanent mallee forms and native forest cover, with carbon sequestration actively estimated using the FullCAM modeling tool.

Both project regions are historically known for broadacre agriculture. The Parkes Shire in NSW is highly recognized for wheat cropping and livestock grazing, featuring a semi-arid to sub-humid climate with historically fluctuating rainfall and soil moisture periods. Soils in the region generally consist of red-brown earths and sandy loams. Similarly, the Shire of Jerramungup in WA is characterized by traditional agriculture, primarily sheep farming and cropping, experiencing a Mediterranean to semi-arid climate. Soils across this region are typically sandy, gravelly, and duplex, making them highly suitable for deep-rooted native tree growth.

Operated with CO2 Australia acting as the project agent, this site forms part of Woodside Burrup Pty. Ltd.'s broader Pluto Carbon Offset Project portfolio, which spans across Stages 1 to 4. These specific offsets are utilized to help Woodside acquit and manage operational greenhouse gas emissions associated with their LNG activities, primarily at the Pluto LNG Facility on the Burrup Peninsula. Originally registered under an older afforestation and reforestation determination in 2013, the project varied its method in September 2024 to the current mallee plantings method.
