Gemma Soil Carbon Project

Gemma Soil Carbon Project is a soil carbon sequestration project located approximately 40km northeast of Narrandera in the Riverina region of NSW. It was registered in February 2024 and covers 1,402.80 hectares.

Soil carbon projects under the 2021 Measurement and Models methodology involve changing agricultural management practices to build soil organic carbon. Standard requirements include establishing a baseline through rigorous soil sampling and subsequently quantifying carbon stock changes via direct measurement or approved modeling over the crediting period.

The Narrandera area is a major agricultural hub known for broadacre cropping and livestock grazing. The region is generally considered semi-arid to temperate with moderate-to-low rainfall, and soils typically consist of red-brown earths, clay loams, and sandy loams.

This project increases carbon in the soil by applying synthetic or non-synthetic fertilisers to the land to address a material nutrient deficiency. Additionally, in October 2025, a variation was made to the project to remove certain areas from the total footprint. It is managed by Loam Carbon Pty Ltd, an Australian ag-tech company specializing in soil carbon sequestration.
