The National Carbon Accounting System is being developed by the Australian Government to provide a complete carbon accounting and projections capacity for land-based (agricultural and forestry) activities.
Early in the development of the NCAS it was recognised that carbon accounting at both continental and project scales was going to rely on both the collation and synthesis of resource information and the calibration and verification of a model framework. The vast land areas in Australia under extensive forest and agricultural management demand an approach founded on modelling. Purely measured approaches were shown to be impractical, particularly for differential land-based accounting systems such as that required by Article 3.3 of the Kyoto Protocol.
