Prosper Carbon Project

Prosper Carbon Project is a soil organic carbon project located near the Grampians National Park, approximately 15km west of Stawell and 7km northeast of Halls Gap in Victoria. It was registered in December 2017 and covers an area of 115.65 hectares.

Soil organic carbon projects involve undertaking new agricultural or land management activities to increase the amount of carbon stored in the soil. Under the 2021 Measurement and Models methodology, this sequestration is quantified using a hybrid approach that combines soil carbon model estimates with direct soil sampling.

The Grampians and broader Wimmera region is well known for its agriculture, including sheep grazing and cropping operations. The area experiences a temperate climate with moderate seasonal rainfall, typically recording around 500mm annually. Local soils can vary significantly but are often characterised by sandy loams near the mountain ranges, merging into heavier, texture-contrast duplex soils (such as Chromosols) across the grazing plains.

This project aims to increase soil carbon within its agricultural system by applying synthetic or non-synthetic nutrients to the land to address a material deficiency, and by re-establishing or rejuvenating pasture through seeding or pasture cropping. Interestingly, the project originally commenced under the older 2014 soil carbon methodology before officially transitioning to the newer 2021 methodology in October 2025. At around the same time in September 2025, the project’s proponent also varied, transferring from Corporate Carbon Solutions Pty Ltd to Agriprove Solutions Pty Ltd.
