Lyne Carbon Project

Lyne Carbon Project is an Estimation of Soil Organic Carbon Sequestration using Measurement and Models project located at Inglewood, approximately 91km east of Goondiwindi and 150km southwest of Toowoomba in Queensland. It was registered in May 2020 and covers 210.55 hectares. In April 2025, a variation was recorded on the registry where some areas originally listed in the project were removed.

The Estimation of Soil Organic Carbon Sequestration using Measurement and Models methodology provides the rules for crediting emissions reductions achieved by increasing the carbon stored in agricultural soils. Under this method, proponents can earn credits by measuring the increase in soil carbon that results from implementing new, eligible land management activities, such as altering grazing patterns or seeding new pastures. The Lyne Carbon Project transitioned to this current 2021 method from the older 2018 soil carbon measurement methodology in January 2024.

The Inglewood area, located on the southern Darling Downs, is historically known for traditional agricultural activities, including sheep and cattle grazing, grain cropping, and timber harvesting. The region experiences a semi-arid to subtropical climate, receiving approximately 500mm to 600mm of annual rainfall. Soils in this region vary but frequently feature traprock-derived profiles, sandstone-derived solodic soils, and grey-brown cracking clays (vertisols) which typically require careful management to maintain structure and infiltration.

This specific project was established to increase carbon in the soil by rejuvenating pastures and altering grazing practices. Managed by Peter and Angus Ramsey in partnership with the proponent, AgriProve Solutions Pty Ltd, the property transitioned from continuous set stocking to a rotational grazing system across 16 separate paddocks. To boost biodiversity and soil function, the managers introduced multi-species pasture mixes, including linseed, chicory, clover, and native grasses, and installed exclusion fencing to manage grazing pressure from kangaroos and wild dogs. Through these regenerative practices, the Lyne Carbon Project generated over $1,100 Australian Carbon Credit Units (ACCUs), while the land managers reported up to a threefold increase in their effective livestock carrying capacity alongside massive improvements in groundcover.
