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

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).

• 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 CMNUCCNAI 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.

  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.
