1. CGE Greenhouse Gas Inventory Hands-on Training Workshop
UNFCCC – NAI SOFTWARE Sector: Industrial Processes Practical Aspects and Exercises
CGE = Consultative Group of Experts on National Communications from Parties not included in Annex I to the Convention
NAI Parties = Parties not included in Annex I to the Convention

2. CONTENT
Details on use of the UNFCCC – NAI Software to calculate and report GHG emissions in the Industrial Processes sector.
Practical exercises (to be solved by the participants after the presentation).

3. 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).

6. SECTOR: INDUSTRIAL PROCESSES Exercise 2.1: Cement Production (I)

Data
Three Portland cement plants operate in the country. Information could not be obtained directly from the plants. The country’s national statistics report only the data included in the following table.

7. SECTOR: INDUSTRIAL PROCESSES Exercise 2.1: Cement Production (II)
Tasks
Using the UNFCCC–NAI Software:
Calculate CO2 and SO2 emissions.
Verify the emissions reported in the Sectoral and Summary Tables.
Fill Table 8A (Overview Table) for the self evaluation of quality and completeness.

8. SECTOR: INDUSTRIAL PROCESSES Exercise 2.1: Cement Production (III)
Steps
Open the software and select in the Industrial Processes sector Worksheet 2-1s1B CO2 from Cement Production (Tier 2).
Enter the amount of clinker produced in the year. Estimate clinker production from cement production (because the clinker fraction is not known use the default value of 95% for Portland cement). Subtract for clinker imports and add for exports (999,970 tonne + 199,994 tonne = 1,199,964 tonne clinker produced).
Add a note in the documentation box clarifying how the quantity of clinker produced in the year was estimated.

9. SECTOR: INDUSTRIAL PROCESSES Exercise 2.1: Cement Production (IV)
Steps
Enter the CO2 EF selected. In absence of data for the clinker lime percentage consider default value of 65% and use default EF (clinker) = tonne CO2/tonne clinker).
Calculate CO2 emissions from clinker production. In absence of data on CKD, apply default correction factor for lost CKD (i.e. add 2% to the CO2 calculated for clinker). CKD correction factor = 1.02
Open the software and select in the Industrial Processes sector Worksheet 2-1s2 SO2 from Cement Production (Tier 1).
Enter the amount of cement produced in the year.
Enter the SO2 default EF for cement production.
Go to the Sectoral and Summary Tables and verify the emission report.

15. SECTOR: INDUSTRIAL PROCESSES Exercise 2.2: Cement Production (I)
Country A: Year: 2000
Data
Three Portland cement plants operate in the country. The production data were collected directly from the plants. The data included information on CaO content of the clinker (67% average clinker lime percentage).
Each plant exported 20% of its annual production of clinker.
All of the CaO was from a carbonate source.

SECTOR: INDUSTRIAL PROCESSES Exercise 2.3: Iron and Steel Production (I)
Country A: Year: 2000
Data
A plant producing iron and steel operates in the country. The data, submitted directly by the plant, included only the iron/steel production and the amount of coke used as reducing agent (80,000 tonne). It was impossible to obtain more details about the chemical composition of the reducing agent and mineral used.

26. SECTOR: INDUSTRIAL PROCESSES Exercise 2
SECTOR: INDUSTRIAL PROCESSES Exercise 2.3: Iron and Steel Production (III)
Steps
Open the software and select in the Industrial Processes sector Worksheet for Metal Production (because detailed data for reducing agents are not available use the Tier 1 Method. This method slightly overestimates emissions; 1–10%)
Enter the mass of reducing agent used (80,000 tonne).
Because country-specific data at the plant level are not available use the default EF for reducing agents in pig iron production (3.1 tonne CO2/tonne reducing agent).

27. SECTOR: INDUSTRIAL PROCESSES Exercise 2
SECTOR: INDUSTRIAL PROCESSES Exercise 2.3: Iron and Steel Production (IV)
Steps
Estimate CO2 emissions.
Add note in the information box explaining that it was impossible to obtain more details about the chemical composition of the reducing agent and mineral used and for this reason the correction of column C is not applied.
Go to the Sectoral and Summary Tables and verify the reported emissions estimates.
Verify that the quantity of coke used as reducing agent was subtracted from the Fuel Combustion sector.
Note: Tier 2 is more accurate but also more data-intensive. Includes a correction for the carbon stored in the metals produced.
