Mount Constellation Carbon Project (Revoked)

Mount Constellation Carbon Project (Revoked) was a soil carbon project located in the Upper Murray region of Victoria, approximately 20km southeast of the township of Corryong. Registered in August 2018, the project covered a modest area of 159 hectares within the Towong Shire Council area. The project operated for nearly seven years before being revoked in July 2025 under section 30 of the Carbon Farming Initiative Rule, which typically indicates a voluntary notification by the proponent to cease the project.

The project utilized the "Sequestering Carbon in Soils in Grazing Systems" methodology. This method requires landholders to undertake specific management activities, such as pasture cropping, cell grazing, or rejuvenating pastures, to increase the amount of organic carbon stored in the soil. These projects require rigorous soil sampling protocols to measure baseline carbon levels and subsequent increases over time to generate Australian Carbon Credit Units (ACCUs).

The Upper Murray region is characterized by a high-rainfall climate, with nearby weather stations like Khancoban recording annual rainfall averages exceeding 900mm. The landscape typically features rolling hills and valleys supporting cattle and sheep grazing, as well as forestry operations. The soils in this high-elevation Victorian border region are predominantly Kurosols and Dermosols, acidic soils with loam topsoils often overlying clay subsoils, which are conducive to pasture growth but can require careful management of acidity and fertility.
