1. A Suggestion for SEEA classifications of energy resources Ole Gravgård Pedersen Statistics Denmark Sejrøgade 11 DK 2100 Ø +45 3917 3488 ogp@dst.dk

2. Two dimensions relevant for SEEA : 1)Classification by type of energy ressource: Coal, oil, gas, etc. SEEA 2003: EA.1 Natural resources EA.11 Mineral and energy resources EA.111 Fossil fuels EA.112 Metallic minerals EA.113 Non-metallic minerals EA.12 Soil resources EA.13 Water resources EA.14 Biological resources 2) Classification by ”quality”/uncertainty: SEEA 2003: Reference to proven, probable and possible reserves (McKelvey type classification) SNA 2008: 12.17 …sub-soil assets are defined as those proven subsoil resources … that are economically exploitable, given current technology and relative prices.

3. New breakdown of EA.11 Mineral and energy - focusing on energy Alignment with the MFA/product classification? Classification by type of energy ressource:

4. Classification by asset characteristics New SEEA classification based on /aligned with the UNFC classification UNFC: United Nations Framework Classification for Fossil Energy and Mineral Resources Endorsed by the UN Economic Commission for Europe, Recommended for worldwide application by the United Nations Economic and Social Council (ECOSOC) (Resolution 2004/233)

5. Geological knowledge (G) Reflects the uncertainty in the estimates. Economic and commercial viability (E) Reflects whether or not there are hindrances to extraction in the social and economic domain. Field project status and feasibility (F) Ranges from early exploration and research projects, to development, production and abandonment projects. UNFC

6. Use the highest level possible, i.e. no more details than needed Main questions: What is the total ressource? How much is recoverable? What is the best estimate of future extraction? Criteria for incorporating UNFC in SEEA:

7. A. Best estimate of reserves The experts’ best bid on what will be extracted in the future (50 per cent probability of extraction ?) B. Other reserves Still recoverable, but lower probability of extraction (Based on high bid – 10 per cent probability of extraction ?) C. Other resources Should hypothetical resources (G4) be left out ?

Best estimate of reserves is those for which suggested extraction costs are lower than US$ 80 per Kg U (1 January 2005).

11. Next steps: - Continue cooperation with the UNFC aiming at complete integration - The UNECE Group of Experts on Harmonization of Fossil Energy and Mineral Resources Terminology (AHGE) is currently working on further harmonizaton of the terminology and a high level version of the UNFC that is largely commodity independent.
