CONTENT

• Details on use of the UNFCCC NAI Software to
  calculate and report GHG emissions in the Energy
  sector.
• Practical exercises (to be solved by the
  participants after the presentation).

BACKGROUND

• The decision trees in the IPCC good practice
  guidance are used to choose a good practice
  method that suits national circumstances.
• The UNFCCC-NAI Software contains, basically, the
  methods of lesser complexity that countries can
  use to prepare their inventories.
• However, in principle, the software can be used
  to report the estimated emissions independently
  of the complexity of method used (Tier 2, 3, etc).

• Steps
• Begin after the steps given in exercise 1.1
• Go to Worksheet 1.3s1 and verify if the fuel
  consumption previously reported in the
  Residential Sector is already included (it comes
  from 1-2 Overview).
• Estimate emission factor (EF) for each fuel per
  sector.
• Enter the EF for each fuel and activity in
  columns B1 to B6 (in this exercise only for the
  Residential Sector).
• The software makes the emission calculation (for
  each fuel, activity and total).

  amount of raw coal produced during the year. The
  production is carried out in underground mines
  located in the same area of the country. The
  average mining depth is approximately 300 m. CH4
  emission came from ventilation systems and
  degasification systems. Mine specific measurement
  data are not available.
