Science needed to assess carbon impacts of timber harvestingFriday 20 Dec 2024
Dr Bill Jackson, Acting President of Forestry Australia said Australian and international studies highlight the potential to lower carbon emissions by producing and using wood products from sustainably managed forests, particularly as substitutes for high-emission building materials. “This paper demonstrates the complexity in accounting for the impacts of changes to forest management on carbon stocks and greenhouse gas emissions from Australian native forests,” Dr Jackson said. “Assessing carbon impacts of forest management needs to consider the full life cycle of forest management, wood production, processing, use and disposal or reuse. The outcome depends heavily on assumptions about initial conditions, harvest intensity, timber recovery, lifetime of forest products, the impacts of wildfire and the time frame of the analysis. The paper points out that it is important to get these assumptions right, otherwise policy makers can be ill-informed about the effects of their decisions on carbon emissions. Dr Jackson said policy makers also need to consider the short, and long-term, impacts on carbon stocks of decisions to reduce or cease native forest harvesting. This includes the impacts of wildfire and reduced professional forest and fire management capacity in agencies responsible for timber production. “This paper has implications for development of new emission reduction methods under Australia’s ACCU scheme. Appropriate, landscape scale analysis using scientifically sound sampling and surveys of carbon stocks and dynamics are required to inform these methods. “The best opportunities are likely to lie in approaches that improve forest management to better integrate conservation, restoration and sustainable production and use of forest products,” Dr Jackson said.
