2. Technical Support Unit, National Greenhouse Gas Inventory Programme, IPCC New scientific and technical knowledge included.  Since 1996 we have a better understanding of sources F gases Non-Energy Product Uses of Fossil Fuels All Defaults & Emission Factors Reviewed Carbon Capture and Storage Harvested Wood Products Wetlands

3. Technical Support Unit, National Greenhouse Gas Inventory Programme, IPCC Gases included  Carbon Dioxide CO 2  Methane CH 4  Nitrous Oxide N 2 O  Hydroflurocarbons HFC  Perflurocarbons PFC  Sulphur Hexaflouride SF 6  Nitrogen Trifluoride NF 3  Trifluoromethyl Sulphur Pentafluoride SF 5 CF 3  Ethers and Halogenated Ethers (e.g., HFE-7200, H- Galden 1040x, HG-10, HG-01)

4. Technical Support Unit, National Greenhouse Gas Inventory Programme, IPCC New Sources  Carbon Capture and Storage  Closed Coal Mines  Lead and zinc production,  Titanium dioxide production,  Various sources of SF 6 (Accelerators, etc),  Liquid crystal display (LCD) manufacturing  Settlements

5. Technical Support Unit, National Greenhouse Gas Inventory Programme, IPCC Emissions from Carbon capture and storage  Carbon captured subtracted from source emissions Captured CO 2 should be metered and subtracted from emission.  Emissions from leakage where they occur (pipelines, transport, storage and injection) Estimated based on industrial experience  Estimates of leakage from geological storage sites. Based on site investigation, models and measurements

6. Technical Support Unit, National Greenhouse Gas Inventory Programme, IPCC Harvested Wood Products (HWP)  UNFCCC has not decided accounting approach So IPCC cannot prefer one “accounting” approach over another  HOWEVER – underlying each accounting approach are some parameters that can be estimated Methodologies to estimate these parameters are given How these parameters are combined to form all accounting methods is given Default methodology for estimating all these parameters – based on FAO data with default variables is suitable for all counties – country specific data will improve estimates

9. Technical Support Unit, National Greenhouse Gas Inventory Programme, IPCC Handling of precursors clarified (SO 2, NOx, CO and NMVOC)  Will not give guidance for the indirect greenhouse gases  Will refer to other existing guidance EMEP/CORINAIR Guidebook  May need to use these for some indirect emissions Only estimate these if inventories already exist
