INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE NATIONAL GREENHOUSE GAS INVENTORIES PROGRAMME UNEP WMO IPCC 2006 Guidelines for National Greenhouse Gas Inventories Simon Eggleston Technical Support Unit
New scientific and technical knowledge included. Ø Since 1996 we have a better understanding of sources üF gases üNon-Energy Product Uses of Fossil Fuels üAll Defaults & Emission Factors Reviewed üCarbon Capture and Storage üHarvested Wood Products üWetlands Technical Support Unit, National Greenhouse Gas Inventory Programme, IPCC
Gases included Ø Carbon Dioxide CO 2 Ø Methane CH 4 Ø Nitrous Oxide N 2 O Ø Hydroflurocarbons HFC Ø Perflurocarbons PFC Ø Sulphur Hexaflouride SF 6 Ø Nitrogen Trifluoride NF 3 Ø Trifluoromethyl Sulphur Pentafluoride SF 5 CF 3 Ø Ethers and Halogenated Ethers (e. g. , HFE-7200, HGalden 1040 x, HG-10, HG-01) Technical Support Unit, National Greenhouse Gas Inventory Programme, IPCC
New Sources Ø Carbon Capture and Storage Ø Closed Coal Mines Ø Lead and zinc production, Ø Titanium dioxide production, Ø Various sources of SF 6 (Accelerators, etc), Ø Liquid crystal display (LCD) manufacturing Ø Settlements Technical Support Unit, National Greenhouse Gas Inventory Programme, IPCC
Emissions from Carbon capture and storage Ø Carbon captured subtracted from source emissions üCaptured CO 2 should be metered and subtracted from emission. Ø Emissions from leakage where they occur (pipelines, transport, storage and injection) ü Estimated based on industrial experience Ø Estimates of leakage from geological storage sites. ü Based on site investigation, models and measurements Technical Support Unit, National Greenhouse Gas Inventory Programme, IPCC
Harvested Wood Products (HWP) Ø UNFCCC has not decided accounting approach ü So IPCC cannot prefer one “accounting” approach over another Ø HOWEVER – underlying each accounting approach are some parameters that can be estimated ü Methodologies to estimate these parameters are given ü How these parameters are combined to form all accounting methods is given ü 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 Technical Support Unit, National Greenhouse Gas Inventory Programme, IPCC
Direct & Indirect CO 2 Technical Support Unit, National Greenhouse Gas Inventory Programme, IPCC
Biogenic Technical Support Unit, National Greenhouse Gas Inventory Programme, IPCC
Handling of precursors clarified (SO 2, NOx, CO and NMVOC) Ø Will not give guidance for the indirect greenhouse gases Ø Will refer to other existing guidance üEMEP/CORINAIR Guidebook Ø May need to use these for some indirect emissions üOnly estimate these if inventories already exist Technical Support Unit, National Greenhouse Gas Inventory Programme, IPCC
