  1. UNFCCC - NAI SOFTWARE Sector: EnergyPractical Aspects and Exercises CGE Greenhouse Gas Inventory Hands – on Training Workshop for the African Region Pretoria, South Africa 18 – 22 September 2006

  2. CONTENT • Specific details of the UNFCCC - NAI Software use to calculate and report GHG emissions in the sector Energy. • Practical exercises (to be solved by the participants after the presentation).

  3. BACKGROUND • The choice of a good practice method is given by the decision threes in the IPCC GPG according to national circumstances. • UNFCCC -NAI Software contains, basically, the methods of smaller complexity that can use countries for the preparation of inventories. • However, in principle, the software can be used to report the estimated emissions independently of the complexity of used method (Tier 2, 3 etc).

  4. Sector: Energy

  5. SECTOR: ENERGYFuel Combustion: CO2_Reference Approach

  6. SECTOR: ENERGYExercise 1.1: CO2 Reference Approach Tier 1 (I) Country A: Year: 2000. Data • The National Statistics Office provided data on the national fuel consumption included in the energy balance for the year 2000. Using the Reference Approach and the CMNUCC–NAI Software determines: • CO2 emissions from liquid fossil fuels. • CO2 emissions from solid fossil fuels. • CO2 emissions from international bunkers. • CO2 emissions from biomass used in energy. • Total CO2 emissions for the country. • Verifies the emissions report in the Short Summary Table.

  10. SECTOR: ENERGYExercise 1.1: CO2 Reference Approach Tier 1 (V) Steps Open the software and select in the Energy sector the worksheet 1-1s1-3 CO2 from Energy Sector (Reference Approach) • To calculate apparent consumption (1000 t) for each fuel enter for primary fuels: production (column A), imports (column B), exports (column C), international bunkers (column D), stock change (column E). For secondary fuels and products enter: imports (column B), exports (column C), international bunkers (column D), stock change (column E). • Enter the conversion factor in column G to obtain the apparent consumption in Tj (column H)

  11. SECTOR: ENERGYExercise 1.1: CO2 Reference Approach Tier 1 (VI) Steps (continuation) • Enter the Carbon Emission Factor in Column D to obtain the carbon content in tC (column J) and Gg C (column K). • In this step the software calculates the carbon stored in products from the data incorporate in the Auxiliary worksheet 1-1a. The country didn’t provide information in this respect. • Enter values for Fraction of Carbon Oxidised in Column N. The software calculates actual carbon emissions (Gg C) in column O. • The software calculates actual CO2 emission (Gg CO2) in column P. • Go to the Worksheets 1-1s4-5 to estimate CO2 emissions from international bunkers. • Go to the Short Summary Report Table (Table 7Bs1) and verify the location and value of reported emission.

  21. SECTOR: ENERGYExercise 1. 2: CO2 by Source Categories Tier 1 (I) Country A: Year: 2000. Worksheet 1-2s12 Residential Sector Data • The National Statistics Office provided the amount and type of fuel combusted in the Residential Sector during the year 2000. These data are included in the following table.

  22. SECTOR: ENERGYExercise 1.2: CO2 by Source Categories Tier 1 (II) Other Data: • Use the following values for the calculation:

  23. SECTOR: ENERGYExercise 1.2: CO2 by Source Categories Tier 1 (III) Tasks Using the UNFCCC – NAI Software: • Calculates CO2 emissions Tier 1 method (Sectoral Approach). • Verify if consumption and the emission are correctly located in Worksheet 1-2 Overview. If the location is not correct modifies it. • Verifies the emissions report in the Sectoral and Summary Tables. • Fills the Table 8A (Overview Table) for the self evaluation of quality and completeness. • Print the used worksheet, the Sectoral Summary Table and the Overview Table (8A)

  24. SECTOR: ENERGYExercise 1.2: CO2 by Source Categories Tier 1 (IV) Steps Open the software and select in the Energy sector the worksheet 1-2s11-12 Residential Sector. • Enter the amount of each fuel consumed in Column A. • Enter the conversion factor to convert to terajoules in Column B. • Enter the Carbon Emission Factor in Column D. • In this step the software calculates the carbon stored in products from the data incorporate in the Auxiliary worksheet 1-2a. The country didn’t provide information in this respect.

  25. SECTOR: ENERGYExercise 1.2: CO2 by Source Categories Tier 1 (IV) Steps (continuation) • Enter values for Fraction of Carbon Oxidised in Column J. • The software estimate actual CO2 emission in column L. • Go to the Worksheet 1.2 and verify the value and location of consumption and emission estimated. • Go to the Sectoral and Summary Report Tables and verify the location and value of reported emission.
