Kelly Carbon Project

The Kelly Carbon Project is a soil carbon sequestration initiative located approximately 15km northeast of the rural town of Miriam Vale and 50km southeast of the major industrial city of Gladstone in Queensland. Registered in October 2020, the project spans 214.39 hectares within the Gladstone Regional Council local government area. The surrounding region is predominantly utilized for beef cattle grazing and forestry, characterized by its sub-tropical coastal environment.

Operating under the Estimation of Soil Organic Carbon Sequestration using Measurement and Models methodology (2021), the project aims to sequester carbon by modifying agricultural management practices. Specifically, the project activities involve altering the stocking rate, duration, and intensity of grazing. This approach, often referred to as time-controlled or rotational grazing, allows pastures to rest and recover, promoting deeper root growth and increasing the deposition of organic carbon into the soil profile.

The environment in the Miriam Vale district generally experiences high, summer-dominant rainfall, averaging between 900mm and 1000mm annually, which is favorable for biomass production. The local soil landscape is typically comprised of coastal forest loams, podzolic soils, and duplex soils (sandy or loamy topsoil over clay subsoil). Notably, in July 2025, the project varied its methodology from the 2018 measurement-based determination to the 2021 hybrid model. This transition allows the proponent, Agriprove Solutions, to utilize modeled estimates alongside physical soil core sampling to calculate carbon credits, potentially reducing the cost of verification.
