Mahon Carbon Project

Mahon Carbon Project is a Soil Organic Carbon project located in the Mackay Region of Queensland, approximately 12km south of the coastal town of Sarina. It was registered in August 2020 and covers 497.20 ha.

Soil Organic Carbon projects involve generating carbon credits by increasing the amount of carbon stored in agricultural soils. This specific methodology requires rigorous modelling or direct measurement, such as core sampling, to demonstrate a verifiable increase in soil organic carbon levels over time.

The Sarina and Mackay regions are traditionally known for sugarcane farming and cattle grazing operations. The area experiences a tropical, high-rainfall climate, and the soils are generally fertile Vertosols (cracking clays), Dermosols, and Chromosols.

This project was set up to increase carbon in the soil by establishing and permanently maintaining a pasture where there was previously limited or no pasture, essentially converting cropland or fallow back to permanent pasture. The project proponent, Agriprove Solutions Pty Ltd, secured an active Optional Delivery contract (CAC548250) with the Commonwealth from the September 2020 auction, committing an original volume of 70,500 tonnes of carbon abatement. In October 2023, the project's methodology was updated to the newer 2021 Soil Carbon Determination to utilize updated estimation and measurement models.
