Broandah Soil Carbon Project

Broandah Soil Carbon Project is a soil carbon sequestration project located in the rural locality of Ganter, approximately 35 kilometers north of Wallumbilla and 70 kilometers northeast of Roma in the Maranoa Region of Queensland. Registered on October 30, 2024, the project covers a project area of 502 hectares. The region is a significant agricultural hub known for beef cattle grazing and cropping, though it also heavily overlaps with the Surat Basin's Coal Seam Gas (CSG) fields.

The project operates under the 2021 Soil Carbon methodology, which credits increases in soil organic carbon (SOC). To achieve this, the proponent, energy major Santos Limited, aims to implement land management activities such as re-establishing pasture through seeding, introducing legumes to fix nitrogen, and altering grazing intensity to improve ground cover. These activities are designed to boost biomass production, thereby drawing more carbon from the atmosphere into the soil profile where it can be measured and credited.

Environmentally, the Maranoa region is classified as semi-arid to subtropical with summer-dominant rainfall averaging around 550mm to 600mm annually. The local landscape features a mix of soil types, often including cracking clays (Vertosols) which are highly capable of holding carbon, as well as sandy red earths (Kandosols). The project is notable as it likely represents an instance of land sector co-existence, where Santos is utilizing its landholdings, potentially associated with its Roma East or GLNG gas field developments, to generate Australian Carbon Credit Units (ACCUs) to offset its own corporate emissions liabilities.
