  1. From product definitions to SIEC (Standard International Energy Classification) What we did, and why we did it Odd Andersen United Nations Statistics Division

  2. GOAL: “SIEC is a standard, statistical classification”

  3. Standard Classifications IMPLEMENT POLICIES (customs, criminal legislation) STANDARDIZE CONCEPTS (jobs, education, natural phenomena) ORGANIZE AND PRESENT STATISTICS Standard Statistical Classifications

  4. “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 http://unstats.un.org/unsd/class/family/bestprac.pdf

  5. APPROACH: Use InterEnerStat product definitions as a basis

  6. 1. Define scope FUELS ELECTRICITYHEAT OUTPUT OF ENERGY INDUSTRIES Scope of SIEC

  7. 2. Completing levels

  8. NOT BUT level 1 level 2 level 3 level 4

  9. 3. Regroup electricity and heat InterEnerStat product definitions SIEC

  10. 4. Aggregating oil and natural gas at highest level InterEnerStat product definitions SIEC

  11. 5. Common aggregation for crude oil InterEnerStat product definitions SIEC

  12. 6. Renaming of categories !!! Not a solid fuel OK. It is a derived product

  13. 7. Include nuclear fuel SIEC scope (reminder): fuels electricity / heat output of energy industries

  14. 8. Explicit formulation of similarity criteria What distinguishes these two? Distinguished by product definitions

  15. 9. Correspondence table CPC (Ver. 2) SIEC HS 2007

  16. Correspondence table – problematic areas waste biogases refinery feedstocks, refinery gas “other oil products”, “other liquid biofuels” heat

  17. OUTCOME: SIEC, top level

  18. SIEC, second level

  19. 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: 2.6.11.0.0 (Lubricants) • Too detailed?

  20. Next steps: Circulation to: UN Expert Group on Classifications London Group
