The influence of crediting and permanence periods on Australian forest-based carbon offset supply

摘要

Governments globally are developing increasingly ambitious carbon emissions reduction schemes that include significant emissions offset credits for forest-based carbon sequestration. Such strategies can present significant challenges in highly modified and intensively farmed regions where forest land use opportunity and establishment costs are high. This article evaluates the economics of land-use change via active afforestation for local carbon abatement in the Australian state of South Australia, a region with high supply costs representative of long-established temperate farming regions. We found that there is no economically viable abatement below $38 tCO(2)e(-1), however up to 154 Mt CO(2)e of abatement could be available up to prices of $50 tCO(2)e(-1).
