GT Carbon Project 1

GT Carbon Project 1 is a Plantation Forestry project located in the Green Triangle region of South Australia, with project parcels ranging from 30km southeast of Mount Gambier to areas further north near Naracoorte. It was registered in September 2023 and originally covered 299.20 hectares, though a variation approved in May 2025 successfully added further areas to the carbon project.

Plantation forestry projects under the avoided conversion activity involve establishing and maintaining a continuous plantation forest rather than allowing the land to be cleared and permanently converted to non-forested agricultural use. Standard requirements dictate that the plantation must be managed for commercial harvesting of wood products, adhere to baseline stocking densities, and use approved modeling tools like FullCAM to accurately measure the net carbon abatement stored within the trees.

The Green Triangle region is well known for its extensive commercial pine and blue gum forestry operations, alongside cattle grazing and cropping. The environment provides ideal timber-growing conditions, characterized by reliable, high rainfall and a mix of sandy loam and limestone-derived terra rossa soils.

The project is operated by Mitsui & Co. Wood Resources Oceania Pty Ltd, who manage the plantation to maximize both wood fibre output and carbon abatement. By matching high-quality seed species to the local soil composition and guaranteeing replanting after commercial harvesting, the proponent ensures a continuous cycle of carbon capture across a 25-year permanence period.
