1. The reference and the sectoral approach in the new Energy Volume Darío R. Gómez Comisión Nacional de Energía Atómica Argentina

2. Energy Volume – IPCC approved Introduction Reference Approach Stationary Combustion Mobile Combustion Mining, Production and Transport of Fuels

3. Reference Approach Based on energy supply statistics Check that all fuel carbon has been accounted for No need to reproduce the same value as the SA Understand/report why it produces a different value Only estimate of CO 2 emissions from fuel combustion An independent second opinion with respect to the Sectoral Approach Clearer guidance on the assessment of the differences Not Good Practice for national estimates of CO 2

4. CO 2 and non-CO 2 When a fuel is burned all the emissions are produced at the same time The separate treatment is a left-over of early GHG inventory methods Integrate the estimation of CO 2, CH 4 and N 2 O For Tiered methods of the Sectoral Approach, fuel combustion amounts are the key statistics

5. Non-energy use Energy related emissions are emissions associated with ○the extraction and production of fuel for any use ○the use of fuel to produce useful energy By definition the non-energy use of fuels should not be dealt with by the Sectoral Approach in the Energy sector but in the Industrial Process and Product Use sector (IPPU) Activity data for fuel combustion exclude quantities of fuels used as feedstock and for other non-energy purposes Boundary between energy related, non-energy related and waste sector emissions ○Non-energy related emissions are all other emissions from industrial process and product use except those covered by the waste sector

6. Tiered Approach Emission gas, fuel = Combustion gas, fuel x Emission Factor gas, fuel Tier 1 ○Data on the amount of fuel combusted in the source category ○A default emission factor as given in the 2006 Guidelines Tier 2 ○Data on the amount of fuel combusted in the source category ○A country specific emission factor for the source category Tier 3 ○Data on the amount of fuel combusted in the source category for each relevant technology ○A specific emission factor for each technology

7. Evolutionary approach 1996 Guidelines 2006 Guidelines Reference Approach CO 2 Tier 1 CO 2 Tier 1 non-CO 2 Tier 1 CO 2, CH 4, N 2 O Reference Approach CO 2
