1 6B.1 1 UNFCCC - NAI SOFTWARE Sector: Energy Practical Aspects and Exercises CGE Greenhouse Gas Inventory Hands – on Training Workshop for the African Region Pretoria, South Africa 18 – 22 September 2006

2 6B.2 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 6B.3 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).

5 6B.5 5 SECTOR: ENERGY Fuel Combustion: CO2_Reference Approach

6 6B.6 6 SECTOR: ENERGY Exercise 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: 1.CO2 emissions from liquid fossil fuels. 2.CO2 emissions from solid fossil fuels. 3.CO2 emissions from international bunkers. 4.CO2 emissions from biomass used in energy. 5.Total CO2 emissions for the country. 6.Verifies the emissions report in the Short Summary Table.
