Diamond Mountain Carbon Project (Revoked)

Diamond Mountain Carbon Project (Revoked) was a soil carbon sequestration project located approximately 1km south of the township of Khancoban in the Snowy Valleys region of New South Wales. Registered in August 2018, the project covered a relatively small area of 240.5 hectares on land typically used for grazing and pasture. The project site sits at the foothills of the Snowy Mountains, adjacent to the Kosciuszko National Park, an area characterized by its scenic alpine valleys and agricultural productivity.

The project operated under the Sequestering Carbon in Soils in Grazing Systems methodology. This method requires landholders to implement new management activities, such as altering stocking density, rejuvenating pastures, or undertaking pasture cropping, to increase the amount of organic carbon stored in the soil. To generate credits, the proponent must measure baseline soil carbon levels and demonstrate a verified increase over time through subsequent sampling.

Environmentally, the Khancoban region is classified as a high-rainfall zone, receiving an average of over 900mm of precipitation annually, which is generally favorable for building soil carbon compared to drier inland regions. The local soils are typically acidic and can include Dermosols or Chromosols, often derived from the surrounding granitic and metamorphic geology of the alpine region.

On July 3, 2025, the project was revoked under Section 30 of the Carbon Credits (Carbon Farming Initiative) Rule 2015. Section 30 refers to a voluntary revocation requested by the project proponent. This often occurs when a project is deemed commercially unviable, the land is sold, or the proponent decides not to proceed with the rigorous monitoring requirements. As a result, this project is no longer active in the Australian Carbon Credit Unit (ACCU) scheme.
