Proceeding: Activity rates stem from GEST (split-calculation in file "FUELS" of LA). Aggregated emission factors from "Emissionsfaktoren; neue CO2-Werte". Actual emissions calculated with actual activity rates and these emission factors.The fraction of stationary motors is so small compared to the total in each fuel, that aggregated emission factors are those from combustion boilers.Petroleum refining with emission factors from EMIS (exception CO2 and N2O LPG); emission factors between 1990 and 1995 interpolated (1995: retrofitting done). Activity rates HFOand LPG from "J ahresberichte Erdölvereinigung".Emissions calculated by multiplying activity rates with emission factors.
Sulfur contents: LFO: 0.0700% HFO: 0.7900%

Advantage of old system
• Simple and stupid, and it works
Problems
• System has grown to a vast, almost un-manageable size (>100 tables, thousands of links)
• Modifications possible, but very error sensitive
• Yearly up-date is hard work
• Knowledge about structure is concentrated to the developer’s head

History of Data handling
Archiving of data
• Inventory database integrated in governmental data processing system (closed environment with high security demands)
• Backups and security on high standard (shadowed disks, daily backups, two different servers at two different locations, daily update of virus software etc.)
Archiving of data is not a problem
Archiving/Documentation of methods
Two pillar strategy:
1) All methods should be documented (or at least referenced) in the MESAP information systemi) through documentation in compilation filesii) through calculation procedures in the CalQlator
2) A comprehensive (reader friendly) overview is given in the National Inventory Report (NIR) (Annexes for details)
Archiving of background information(incl. decisions/reasons)
• Includes all “soft” data, which are indirectly linked to data in EMIS or NIR, e.g. - Annual reports from industry (activity data)- Reports about methods (referenced in EMIS, NIR)- Reasons of selection of methods, activity data- Documentation of decisions made during inventory preparation
Remaining problems
• Archiving of background information, mainly decisions / reasons
• Inclusion of LULUCF data in EMISLand use change data is different in structure from emission data
Inventory preparation and production will remain a step by step improving process which will (probably) never find the final top-level product. Pragmatic, country-adapted solutions are needed.
