  2. 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

  3. 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

  4. 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

  5. Implication of NGGI approaches .Pool developed since 1970 – this sets the base for production approaches

  6. 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

  7. 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

  8. 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
