The Blackall Carbon and Biodiversity Project 2 (Revoked)

The Blackall Carbon and Biodiversity Project 2 (Revoked) was a carbon farming initiative located approximately 75km south-west of the township of Blackall in Central West Queensland. Registered in September 2023, the project covered a significant area of 11,224 hectares within the Blackall-Tambo region. However, the project was revoked on August 31, 2025, just under two years after its registration. The revocation occurred under section 30 of the Carbon Credits (Carbon Farming Initiative) Rule 2015, which indicates a voluntary revocation application was made by the proponent, Carbon Neutral Pty Ltd.

The project operated under the Human-Induced Regeneration (HIR) methodology. This method focuses on regenerating permanent even-aged native forests by addressing the suppressors that prevent regrowth. In this specific context, the project activities involved managing grazing pressure and ceasing mechanical or chemical destruction of vegetation. The goal was to allow native species, likely Gidyea or Eucalypt woodlands common to the area, to regenerate from in-situ seed sources and rootstock until they achieved forest cover status.

Environmentally, the region is characterized by a semi-arid climate with highly variable rainfall, averaging roughly 500mm annually. The landscape in this part of the Blackall-Tambo region typically consists of Mitchell grass downs and open woodlands. The soils are predominantly fertile but heavy grey and brown Vertosols (cracking clays), often referred to as "black soil plains," which are traditionally used for sheep and cattle grazing. The project's title, including "Biodiversity," suggests the proponent intended to market the credits with co-benefits, aligning with their history of developing biodiversity corridors.
