Content a)Details on use of the UNFCCC-NAI Software to calculate and report GHG emissions in the waste sector. b)Practical exercises (to be solved by the participants after the presentation). 2 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

a)The decision trees in the IPCC good practice guidance (GPG 2000) are used to choose a good practice method that suits national circumstances. b)The UNFCCC-NAI Software contains, basically, the methods of lesser complexity that countries can use to prepare their inventories. c)However, in principle, the software can be used to report the estimated emissions independently of the complexity of method used (Tier 2, 3, etc).

Country A: Year: 2000. Worksheets 6-2s1 to 6-2s4 Data The National Statistics Office has provided the information included in the following table. Population (1000 persons) Degradable organic component Fraction of DOC removed as sludge Methane recovered 18 250.515 330 kg BOD/1000 persons/yr 05 000 tonne Exercise 1: CH 4 Emissions from Domestic and Commercial Wastewater and Sludge Handling (I) 10 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)
11
Other Data: Use the following values for the calculation: Wastewater handling systemFraction of wastewater treated by the handling system Methane conversion factor for the handling system Collected (sewered to plant) Lagoons (anaerobic deep) 0.020.8 Not specified 0.050.75 Uncollected (treated on site) Latrines and septic systems 0.30.15 With regular sediment removal Exercise 1: CH 4 Emissions from Domestic and Commercial Wastewater and Sludge Handling (II) 11 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)
12
Tasks Using the UNFCCC-NAI Software: Calculate net CH 4 emissions Verify the emissions report in the Sectoral and Summary Tables Fill in 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.

14
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 CH 4 emissions.

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 CH 4 emissions from the disposition of solid waste on land using the UNFCCC- NAI Software. Verify the results obtained in the Sectoral Report Table and the Summary Tables of the Inventory.
