Nulla Carbon

Nulla Carbon is a Human-Induced Regeneration (HIR) project located in the Mulga Lands bioregion of South West Queensland, approximately 60km north-east of Cunnamulla. Registered in September 2015, the project covers a substantial area of 60,188 hectares. The project operates within the Paroo Shire, a region traditionally dominated by grazing for sheep, cattle, and goats. The Dunsdon family, long-established graziers in the district, have historically managed the "Nulla" station property associated with this project.

The project operates under the Human-Induced Regeneration (HIR) methodology, which involves regenerating permanent native forests on land where vegetation was previously suppressed. Key activities for this project include managing the timing and extent of grazing and controlling feral animals to allow native vegetation, primarily Mulga (Acacia aneura) and Poplar Box, to regenerate. To generate Australian Carbon Credit Units (ACCUs), the project must demonstrate that the suppression of regrowth has ceased and that the land is on a trajectory to achieve forest cover (at least 20% canopy density) within the crediting period.

The environment in this part of the Paroo Shire is semi-arid, characterized by highly variable summer-dominant rainfall averaging between 300mm and 400mm annually. The landscape features flat to undulating plains with red earth soils (kandosols) and clay soils in lower-lying alluvial areas. These conditions support the resilient Acacia woodlands targeted for regeneration.

Interestingly, the project has undergone significant administrative restructuring since its inception. Originally registered with specific Dunsdon family corporate trustees, the proponent role shifted to Corporate Carbon Solutions briefly in 2020 before settling with Ninal Ventures Pty Ltd and Lanin Holdings Pty Ltd. These entities appear to be special purpose vehicles holding multiple carbon projects in the Paroo region, including the nearby Paroo River North and Paroo River South projects. The Dunsdon family are notable in the district for their early adoption of organic production for wheat and lamb, highlighting a history of innovative land management. A minor relinquishment of 434 ACCUs occurred in 2018, likely a routine compliance adjustment regarding eligible interest holder consents or mapping corrections.
