Lyne Carbon Project

The Lyne Carbon Project is a soil carbon sequestration initiative located near the locality of Inglewood, approximately 50 kilometers west of Warwick in the Southern Downs region of Queensland. Registered in May 2020, the project currently covers a project area of 210.55 hectares, operating within a larger 809-hectare grazing property managed by landholders Peter Ramsey and Angus Ramsey.

This project operates under the Estimation of Soil Organic Carbon Sequestration using Measurement and Models Methodology Determination 2021. This methodology requires the proponent to establish a baseline of soil carbon through physical sampling, implement new land management activities to sequester carbon, and subsequently measure or model the increase in soil organic carbon stocks over time. The specific activities employed at Lyne include transitioning from set stocking to high-intensity rotational grazing across 16 paddocks, installing exclusion fencing to manage wild dog and kangaroo pressure, and pasture cropping with diverse species such as linseed, chicory, and clover.

The region surrounding Inglewood and Karara is characterized by a warm temperate climate with summer-dominant rainfall, typically averaging around 600mm to 650mm annually. The area is well-known for sheep and cattle grazing on "Traprock" soils, a type of sedimentary soil common to the district that can be shallow and stony but is responsive to regenerative management.

An interesting milestone for the Lyne Carbon Project was the issuance of its first 1,114 Australian Carbon Credit Units (ACCUs) in June 2025, validating the carbon gains achieved through the management changes. The project has undergone administrative updates, including a methodology variation in 2024 to move from the 2018 "Measurement" method to the 2021 "Measurement and Models" method, likely to optimize monitoring efficiency.
