national carbon accounting system Context  There are many (sequential) dimensions to reporting emissions from harvested wood products (HWP) –Inventory principles (where and when accounted, where reported in inventory, what gases and pools to what sectors etc.) –Policy parameters – use of baselines, exclusions eg. primary or secondary products –Accounting method - gross/net effects, commencement time etc –Technical implementation – model/inventory development

national carbon accounting system Key Principles  Australia has recognised that the key principles of inventory should be adhered to: –Reporting of emissions where and when they occur –No double counting across inventory sectors –Should be consistent with effects on atmosphere –Should use simple methods with potential for Tiers of application

national carbon accounting system Australia’s Current NGGI Reporting  NGGIs have reported emissions from increasing stock of wood products  Growing HWP stocks established by modelling of forest production and consumption statistics maintained since 1944 and published Quarterly –Imports and exports also monitored  Approach uses simple decomposition and does not acknowledge landfill and recycling effects

national carbon accounting system Implication of NGGI approaches. Pool developed since 1970 – this sets the base for production approaches

national carbon accounting system Australia’s Technical Progress  Revised modelling to include additional pools and emissions: –Landfill –Recycling –Bioenergy  Decomposition variable according to age in service life, and separation of service life and disposal pools  Incorporation of Monte Carlo capability to identify model sensitivities

national carbon accounting system

Ongoing Research  Guided by sensitivity analysis: –Landfill excavation –Rates of recycling –Service life retentions/losses –Forms of gases from landfill –Processing wastage –Use of bioenergy

national carbon accounting system Australia’s Position  The proper sequence of policy and technical decisions by appropriate bodies –Policy, principles and accounting method need to be determined by Parties –Technical implementation IPCC  Concurs with current position regarding the need for decisions by COP/MOP before technical guidance/development
