UNFCCC NAI SOFTWARE Sector WastePractical
Aspects and Exercises

CONTENT

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

BACKGROUND

• The decision trees in the IPCC good practice
  guidance (GPG2000) 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).

Handling (III)

• Tasks
• Using the UNFCCC-NAI Software
• Calculate net CH4 emissions.
• Verify the emissions report in the Sectoral and
  Summary Tables.
• Fill Table 8A (Overview Table) for the self
  evaluation of quality and completeness.
• Print the worksheet used, the Sectoral Summary
  Table and the Overview Table (8A).

• Steps
• Open the software and select in the Waste sector
  Worksheet 6-2s1 Estimation of Organic Wastewater
  and Sludge.
• Specify in column A that the estimation is for
  all country.
• Enter population data in Column B, and DOC in
  column C.
• Specify the Fraction of DOC removed as sludge.
  The software calculates the Total
  Domestic/Commercial Organic Wastewater.

Handling (V)

• Steps
• Go to Worksheet 6-2s2 and specify in column A the
  Wastewater Handling Systems used in the country.
• Enter in column B the Fraction of Wastewater
  Treated by the Handling Systems and in C the
  Methane Conversion Factor. Enter in E the Maximum
  Methane Producing Capacity (0.6 kg CH4/kg BOD).
  The software calculates the EF.
• Go to Worksheet 6-2s4 and enter in D the Methane
  Recovered. The software calculates Net CH4
  emissions.

from Solid Waste Disposal on Land (I)

• Country A Year 2000.
• Data
• The Environment Ministry provided data on solid
  waste disposal in the country during the year
  2000. It also provided results from studies
  carried out on solid waste characterization.
• Determine the CH4 emissions from the disposition
  of solid waste on land using the UNFCCC-NAI
  Software.
• Verify in the Sectoral Report Table and the
  Summary Tables of the Inventory the report of
  results obtained.
