Iwatani Forests Carbon Farming Project

The Iwatani Forests Carbon Farming Project is a plantation forestry project located approximately 5 kilometers southeast of Nannup in the South West region of Western Australia. Registered on September 5, 2023, the project covers a relatively focused area of 84.18 hectares. The project is situated within the Shire of Nannup, a region historically defined by its timber industry and high-rainfall agriculture. The surrounding landscape consists of a mix of native Jarrah and Karri forests, commercial timber plantations, and grazing land.

Operating under the Carbon Credits (Carbon Farming Initiative, Plantation Forestry) Methodology Determination 2022, the project employs a hybrid approach. It involves establishing new plantation forests where none previously existed and converting existing short-rotation plantations (typically harvested quickly for woodchips or pulp) into long-rotation plantations (managed for higher-value sawlogs). By extending the rotation period, the trees grow larger and store carbon for longer durations before harvesting. The methodology requires that the project allows for commercial harvesting, distinguishing it from permanent environmental plantings, while ensuring a long-term increase in average carbon stocks.

The project is located in a high-rainfall zone, which is critical for supporting the rapid growth rates required for commercial forestry. The soils in the Nannup area are typically lateritic gravels and loams associated with the Darling Plateau, offering good drainage and fertility for pine or eucalypt species. A notable aspect of this project is its proponent, Iwatani Forests Pty Ltd, a subsidiary of the Japanese energy conglomerate Iwatani Corporation. While Iwatani is best known globally for LPG and hydrogen energy, its expansion into Western Australian forestry, referenced in corporate filings as a "60 ha pine plantation proposal" in Nannup, demonstrates a strategic move into carbon offsetting to complement its energy portfolio.
