Blewett Carbon Project 2

Blewett Carbon Project 2 is a soil carbon sequestration project located approximately 5km northwest of the rural locality of Westmar, in the Western Downs region of Queensland. Registered in December 2022, the project covers a project area of roughly 337 hectares. The surrounding Western Downs region is a major agricultural hub, predominantly utilized for cattle grazing and broadacre cropping, characterized by its flat to gently undulating plains.

The project operates under the Estimation of Soil Organic Carbon Sequestration using Measurement and Models Methodology Determination 2021. This high-integrity methodology requires the proponent to demonstrate a measurable increase in soil carbon stocks over time compared to a baseline. To achieve this, the project involves implementing new land management activities, such as altering stocking rates to improve vegetation cover, installing multispecies pastures, or applying soil ameliorants. These changes are designed to boost plant growth and root biomass, which in turn draws carbon dioxide from the atmosphere and stores it in the soil.

Environmentally, the Westmar area sits within a semi-arid to sub-tropical transitional zone. The region typically receives an average annual rainfall of approximately 460mm, which can be variable. The local soil profile is characteristic of the Brigalow Belt, often featuring grey cracking clays (Vertosols) and red earths (Kandosols/Dermosols). These clay-rich soils are generally well-suited for soil carbon projects due to their capacity to protect organic matter from decomposition when managed correctly.

This project is part of a larger aggregation of projects developed by Agriprove, Australia's largest soil carbon project developer. The existence of multiple "Blewett" projects (such as Blewett Carbon Project 1 and 5) suggests a coordinated approach across multiple land parcels or a phased registration strategy by the landholder. By focusing on grazing management, the project aims to simultaneously generate Australian Carbon Credit Units (ACCUs) and improve the productivity and drought resilience of the farming enterprise.
