INTRODUCTION TO THE USE OF THE UNFCCC - NAI GREENHOUSE GAS

INVENTOY SOFTWARE

CGE Greenhouse Gas Inventory Hands – on Training Workshop for

the African Region

Pretoria, South Africa

18 – 22 September 2006

2 6A.2

CONTENT

During the workshop are included the following presentations related with the UNFCCC - NAI Software:

1. Introduction to the use of the UNFCCC - NAI Inventory Software (version 1.3).

2. Sectoral presentations. Include:a) Specific details of the UNFCCC -NAI Software use

to calculate and report GHG emissions in the sectors: Energy; Industrial Processes; Agriculture; Land-use Change and Forestry (two options: Revised IPCC Guidelines, 1996 and IPCC GPG-LULUCF, 2003) and Waste

b) Practical exercises (to be solved by the participants during and after the presentations).

3 6A.3

This software, produced by the UNFCCC Secretariat, will support non-Annex I Parties in the compilation of their national greenhouse gas (GHG) inventories and in the preparation of their national communications.

This software is used for two main objectives:1) To calculate the emissions in the different sectors

and source categories. 2) To report the emissions by sectors and source

categories and the national inventory at country level.

¡Using the software It is always possible report a complete inventory independently of the method used to calculate the emissions!

UNFCCC - NAI GHG INVENTORY SOFTWARE

4 6A.4

The software is based on the commercial spreadsheet application Microsoft Excel.

You must have Excel 2000 or a later version installed on your computer to be able to run this software.

Note: There are difficulties to start the software using Windows 2003 if it not contains the Visual Basic Library 4.0

UNFCCC - NAI GHG INVENTORY SOFTWARE Design/Environment

5 6A.5

In general, this software uses Tier 1 methodologies for estimating GHG emissions and removals for all source categories described in the Revised 1996 IPCC Guidelines.

However, for some source categories it is possible to use Tier 2 methods recommended in IPCC-GPG 2000 using variants included in the the worksheets or modifying these lightly. Also it is possible to use methods from 2003 IPCC-GPG-LULUCF.

Even if higher-tier methods are chosen to estimate emissions/removals, the summary tables in this software can still be used for reporting.


Methodologies

6 6A.6

The software is based on the IPCC inventory software version 1.1, but has additional characteristics not present in the IPCC software. These are described in Sections 4 and 5 of the software manual.


Methodologies

7 6A.7

For example, a new module (Module 5B) has been added to the present software so that inventory compilers may apply the more recent methodologies developed by the IPCC to the Land Use, Land-Use Change and Forestry (LULUCF) sector, as described in the IPCC Good Practice Guidance for Land Use, Land-Use Change and Forestry (2003 GPG-LULUCF).

The UNFCCC encourages the use of these methodologies, though the user may still choose to use the outdated Module 5 Land-Use


Methodologies. New Characteristics

8 6A.8

In the Good Practice Guidance and Uncertainty Management (2000) the IPCC developed the concept of a key source and in the Good Practice Guidance for Land Use, Land-Use Change and Forestry (2003) this was extended to the more general concept of a key category.

The software contains a tool that links directly to the summary tables and allows the user to perform both level and trend key category analyses.



9 6A.9



For non-Annex I Parties the use of tables contained in decision 17/CP.8 is encouraged.

These tables are included in the software and are (partly) filled automatically, so that once the inventory has been compiled using this software, the time for preparing the reporting tables can be kept to a minimum.

10 6A.10

Table 1 and 2 of the UNFCCC Guidelines are very similar to

Table 7A (Summary

Report) of the UNFCCC-NAI

Software)

11 6A.11

12 6A.12

UNFCCC – NAI GHG INVENTORY SOFTWARE Documentation Boxes. New Characteristics

It is recommended introduce notes in the worksheets and tables of the software that clarify, among other aspects for example:

1) If the estimates carried out are complete or representatives only of a part of the country or activity.

2) Informations on the methods, data and factors used, especially if they are not those included in the IPCC Guidelines, GPG2000 and GPG-LULUCF, 2003.

The software provides boxes in each worksheet for documenting data sources and individual steps in the inventory preparation and to include any clarifications considered necessary.

13 6A.13

UNFCCC - NAI GHG INVENTORY SOFTWAREBenefits

In estimating GHG emissions and removals, and in reporting these to the UNFCCC, the software offers multiple benefits.

It guides the user in a simple step-by-step approach through the emission/removal calculations, which can easily be followed for Tier 1 with the instructions given in the Revised 1996 IPCC Guidelines and the 2003 IPCC Good Practice Guidance (LULUCF);

It helps to avoid potential mistakes/inconsistencies in the inventory preparation and enhances transparency;

It helps to save resources, in particular time;

14 6A.14

UNFCCC – NAI GHG INVENTORY SOFTWAREBenefits

It facilitates the reporting to the UNFCCC, as well as the management of data;

It offers a uniform data management system for inventories from more than one year. This is particularly useful in trend analyses, such as the Key Category Trend Analysis, for which this software provides a tool;

15 6A.15

UNFCCC – NAI GHG INVENTORY SOFTWAREBenefits

In the preparation of the 2000 GHG inventory it is recommended to revise the data provided in previous inventories.

Parties wishing to report for years other than 1990 or 1994 and 2000 are welcome to do so.

The UNFCCC -NAI Inventory Software facilitates the recalculation of emissions in previous inventories and the report of inventories for different years.

16 6A.16

UNFCCC - NAI GHG INVENTORY SOFTWAREWhere to get the software and its manual?

Either on CD-ROM or from Internet. CD-ROM version included in: GCE NAI Training Package on

If no inventory exists yet for this year, you will be prompted with a dialogue box asking whether you would like to create a new inventory for that year.

Click ‘Yes’ to start your inventory, if you choose ‘No’ the software will close.

25 6A.25

UNFCCC - NAI GHG INVENTORY SOFTWARESelecting a year to use as a template

You will then be asked to select an inventory to use as a template.

From the drop-down list, you can select a year which already contains inventory data or you can select a set of blank sheets.

If you would like to use the format and data from a previous year’s inventory as a starting point, select a year from the list.

If you would like to start with a blank set of worksheets, select Blank sheets from the list.

26 6A.26

UNFCCC - NAI GHG INVENTORY SOFTWARELoading the file Overview.xls

Once you have created an inventory, the next time you start the software this inventory will appear in the drop-down list.

After you have selected the inventory you would like to work with, the Overview module opens automatically (Excel will load the file called Overview.xls).

27 6A.27

UNFCCC - NAI GHG INVENTORY SOFTWARELoading the file Overview.xls

The Overview file contains the reporting tables from the Reporting Instructions (Volume 1, IPCC Guidelines) and other general information relating to your inventory.

It will be open at all times when you are running the software. This is to make sure that all the calculations are updated as you work.

28 6A.28

UNFCCC - NAI GHG INVENTORY SOFTWAREThe Overview module

The Overview module serves two purposes: First, from here the modules for individual sectors can

be accessed through the menu bar; and Second, the Overview module contains summary

tables that can be used for reporting, and also the Key Category Analysis tool that can be used for identifying key categories in the inventory.

29 6A.29

You can also click on the tabs at the bottom of the window to move from one sectoral report to another and to the summary tables.

The tabs are labeled using the same format as the IPCC Workbook and Reporting Instructions and the 2003 Good Practice Guidance for Land Use, Land-Use Change and Forestry (Module 5B).

In the Overview module, the tabs are labeled with Summary Table names. For all the sector worksheets (Energy, Industrial Processes, Agriculture, Land-Use Change and Forestry, Waste) the tabs are labeled with the number of the worksheet and the number of the sheet within that worksheet.

Alternatively, you can also use the Ctrl-PageUp/Ctrl_PageDown keys to navigate in the workbook as usual.

35 6A.35

UNFCCC - NAI GHG INVENTORY SOFTWARESelecting a sector to work on

Click on Sectors at the top and select the sector you will work with (e.g. Energy, Industrial Processes, Agriculture, etc.: Modules 1, 2, 4, 5, 5B, 6 [1].

A new file will be opened when you select a sector. This file contains the worksheets from the workbook for that particular sector.

[1] There is no Module 3 for “Solvent and Other Product Use” provided in this software since there is no workbook methodology provided in the Revised 1996 IPCC Guidelines.

36 6A.36

UNFCCC - NAI GHG INVENTORY SOFTWARECompleting your inventory

After choosing the sector you wish to work on and the file has been opened, use the instructions in the workbook to fill in the required information for making the emission estimates.

The workbook contains detailed explanations on how the calculations should be made.

Users are encouraged to provide additional documentation in the worksheets.

37 6A.37

UNFCCC – NAI GHG INVENTORY SOFTWARE Completing your inventory

After you fill in the information for the selected sector (e.g. Energy) you should save the changes by selecting File>Save.

To move to another sector :

1) Click on Window and select Overview.xls from the menu. This will take you back to the Main Menu.

2) Click on Sectors again and choose a new sector.

38 6A.38

GHG INVENTORY SOFTWARE Saving the changes

Once you have completed the data and saved the changes, the values are transferred automatically to Sectoral Tables.

Also, the values are transferred automatically from the Sectoral Tables to the Summary Report Tables (7As1 - 7As3), and the Short Summary Report (7Bs1).

39 6A.39

UNFCCC – NAI GHG INVENTORY SOFTWARE Sectoral and summary tables. General recommendations

Don't trust in the automatic filled of the Sectoral report and Summary tables.

Diverse causes may produce that in this automatic filled arise errors that falsify the emissions obtained for the sector and the inventory.

Carry out a meticulous checkup of the worksheets and verify if their results have been appropriately transferred to the tables of Sectoral report.

After it verifies that an appropriate correspondence exists between the Sectoral report tables and the Summary tables.

40 6A.40

UNFCCC – NAI GHG INVENTORY SOFTWARE Sectoral and summary tables. General recommendations

Also remember that in the tables of Sectoral report and Summary, should be incorporated manually the emissions obtained:

a) In those source categories in which the software doesn't have worksheets or,

b) In those that were carried out estimates using methods different to the one included in the software.

41 6A.41

The protection function can be disable, however, to allow the user to modify the format and contents of the worksheets.

Is recommended that the modifications in the disabled worksheets are only made, if you have enough domain of the application Excel.

For example, to force the introduction of a result (value) in certain estimate, could erase an instruction, links etc., and to introduce errors in the estimates or in the software operation.

WARNING:

If you introduce a modification makes sure that all the formulas and links remain correct and when finishing, protect again the worksheet

46 6A.46

UNFCCC - NAI GHG INVENTORY SOFTWARE Disabling the protection

The protection function is located at the bottom of the Edit menu item (in other Excel versions it is in tools or in a window that appears making right click in any command of the main menu)

If you select Unprotect Sheet you will disable the protection on the current sheet.

If you select Unprotect Workbook, you will disable the protection on the entire Excel workbook (the file you are working in).

47 6A.47

UNFCCC – NAI GHG INVENTORY SOFTWARE Disabling the protection

You might want to disable the protection on a worksheet to:

1. increase or decrease the width of a column;

2. add colour to a cell, or change a formula;

3. add a row or column to the worksheet, perhaps to add a sector, fuel type, domestic livestock type etc.

You might want to disable the protection on a workbook to:

1. add or delete worksheets from the workbook;

2. copy or move worksheets from one workbook to another.
