Nulla Carbon

Nulla Carbon is a Human-Induced Regeneration (HIR) project located on Nulla Station, approximately 15km north of Cunnamulla in South West Queensland. It was registered in September 2015 and covers an expansive 60,188.98 hectares.

Human-Induced Regeneration projects involve establishing permanent native forests through assisted regeneration from in-situ seed sources, including rootstock and lignotubers. The methodology requires land managers to cease suppressive activities on land that was cleared of vegetation or where regrowth was suppressed for at least 10 years prior to the project's commencement. For this project, standard requirements involve stopping the mechanical or chemical destruction of regrowth, managing the timing and extent of livestock grazing, and humanely managing feral animals. This allows the regenerating native forest to reach the standard methodology threshold of at least 20% crown cover and 2 metres in height.

The Cunnamulla region is a semi-arid environment historically known for sheep and cattle grazing, particularly Merino sheep and Angus cattle. Soils in the area generally consist of a mix of sandy loams, red earths, and cracking clay soils (Vertosols) near river systems like the Warrego River.

Nulla Station is heavily associated with the Dunsdon family, who have a long history of grazing in the district. The carbon project has seen several administrative changes since its inception, including variations to the project area in 2015, 2018, and 2019. Interestingly, in June 2018, the Clean Energy Regulator issued a notice requiring the relinquishment of 434 Australian Carbon Credit Units (ACCUs) in relation to the project. Corporate Carbon Solutions was also previously involved as a participant before the project was transferred entirely to the current proponents, Ninal Ventures Pty Ltd and Lanin Holdings Pty Ltd, in 2020. ACCUs generated by the Nulla Carbon project have been successfully issued and purchased by organisations such as the Australian Meat Processor Corporation to meet Climate Active carbon neutral certification goals.
