Nulla Carbon

Nulla Carbon is a Human-Induced Regeneration (HIR) project located in the Paroo Shire of south-west Queensland, centered roughly around the "Nulla Station" property approximately 15 to 20 kilometers north of Cunnamulla. Registered in September 2015, the project covers a massive area of approximately 60,188 hectares, likely spanning multiple aggregated properties given the significant distance between its registered coordinates (ranging from north-east to south-west of Cunnamulla).

The region lies within the Mulga Lands bioregion, an area traditionally dominated by sheep and cattle grazing. The environment is semi-arid, typically receiving 300-400mm of rainfall annually, and is characterized by flat to undulating plains with red earth (kandosol) and sandy loam soils. The native vegetation here consists primarily of Mulga (Acacia aneura) and Poplar Box woodlands.

As a Human-Induced Regeneration project, Nulla Carbon generates credits by allowing native forests to regenerate rather than planting new trees. The project activities involve suppressing the drivers of deforestation, specifically by managing the timing and extent of livestock grazing and ceasing mechanical clearing that was historically used to suppress regrowth. This change in land management allows the underlying rootstock and seed banks to regenerate into "forest cover" (defined as trees over 2 meters tall with at least 20% canopy cover).

The project has a notable administrative history. It was originally registered by the landholders (various Dunsdon family trusts), who are long-term graziers in the district. Ownership of the carbon project subsequently transferred to Corporate Carbon Solutions, a major aggregator, and finally to the current proponents, Lanin Holdings Pty Ltd and Ninal Ventures Pty Ltd. In 2018, the project was subject to a relinquishment notice requiring the return of 434 Australian Carbon Credit Units (ACCUs), a relatively minor compliance correction in the context of a project of this scale.
