From product definitions to SIEC (Standard International Energy Classification) What we did, and why we did it Odd Andersen United Nations Statistics Division GOAL: SIEC is a standard, statistical classification Standard Classifications Standard Statistical Classifications IMPLEMENT POLICIES (customs, criminal legislation) STANDARDIZE CONCEPTS (jobs, education, natural phenomena) ORGANIZE AND PRESENT STATISTICS Standard statistical classifications represent a subset [of standard classifications] used to organize and present statistics When adopting or adapting a standard classification for statistical use, further methodological work may be required Source: Standard Statistical Classifications: Basic Principles APPROACH: Use InterEnerStat product definitions as a basis FUELS ELECTRICITY HEAT 1. Define scope OUTPUT OF ENERGY INDUSTRIES Scope of SIEC 2. Completing levels NOTBUT level 1 level 2 level 3 level 4 3. Regroup electricity and heat SIECInterEnerStat product definitions 4. Aggregating oil and natural gas at highest level SIECInterEnerStat product definitions 5. Common aggregation for crude oil SIECInterEnerStat product definitions 6. Renaming of categories !!! Not a solid fuel OK. It is a derived product 7. Include nuclear fuel SIEC scope (reminder): fuels electricity / heat output of energy industries 8. Explicit formulation of similarity criteria Distinguished by product definitions What distinguishes these two? 9. Correspondence table CPC (Ver. 2) HS 2007 SIEC Correspondence table problematic areas waste biogases refinery feedstocks, refinery gas other oil products, other liquid biofuels heat OUTCOME: SIEC, top level CodeTitle 1Solid fossil fuels and derived products 2Oil, natural gas and derived products 3Nuclear fuels 4Biofuels and waste 5Electricity 6Heat SIEC, second level CodeTitle 1Solid fossil fuels and derived products 11Coal 12Peat 13Oil shale 2Oil, natural gas and derived products 21Crude oil 22Natural gas 23Natural gas liquids (NGL) 24Refinery feedstocks 25Additives and oxygenates 26Oil products 3Nuclear fuels 31Uranium and plutonium 32Other 4Biofuels and waste 41Biofuels 42Waste 5Electricity 51Electricity from fossil fuels 52Electricity from nuclear fuels 53Solar electricity 54Electricity from wind energy 55Electricity from hydro energy 56Electricity from wave energy 57Electricity from tidal energy 58Electricity from other marine energy 59Electricity from geothermal energy 6Heat 61Heat from fossil fuels 62Heat from nuclear fuels 63Solar heat 64Heat from geothermal energy How can we improve SIEC? SCOPE is it good? Hierarchy can it be improved? Simpler coding system? XXXXX is better than X.X.X.X.X but: (Lubricants) Too detailed?
