CGE Greenhouse Gas Inventory Hands – on Training Workshop for the African Region Pretoria, South Africa 18 – 22 September 2006 UNFCCC - NAI SOFTWARE Sector: Land-Use Change and Forestry Practical Aspects and Exercises

CONTENT Specific details of the UNFCCC -NAI Software use to calculate GHG emissions in the sector Land-Use, Land-Use Change and Forestry. Practical exercises (to be solved by the participants after the presentation).

BACKGROUND The choice of a good practice method is given by the decision threes in the IPCC GPG-LULUCF according to national circumstances. The UNFCCC -NAI Software contains, basically, the methods of smaller complexity that can use countries for the preparation of inventories. However, in principle, the software can be used to report the estimated emissions independently of the complexity of used method (Tier 2, 3 etc).

LUCF Sector: IPCC 1996 Guidelines Methodology Can be implemented at different levels of complexity and geographic scales: A simple first order approach based on very aggregate default data (default approach), A more accurate level can be achieve substituting country-specific values for general defaults.

LULUCF Sector: GPG2003 GPG2003 use (and the higher Tiers) for GHG inventories, is encouraged to reduce the uncertainty of emission estimates. The GPG2003 besides providing good practice for the LULUCF Sector (not covered in GPG2000): overcomes many of problems detected in the use of the IPCC 1996 GL for LUCF, update information's necessary for the calculations (AD, EF and other emission parameters).

LULUCF Sector: IPCC GPG2003 Methodology Uses the same basic conceptual approach as in IPCC Guidelines but with some important inclusions, updates and improvements. Provides three hierarchical Tiers of methods (nearly correspond to the three levels of complexity of IPCC GL). Land-use category base approach (forest land, cropland, grassland, wetland, settlement and others). A division is also made based on the status and recent history of the land use: a) lands that begin and end an inventory period in the same use, b) lands conversions to other land use.

LULUCF Sector: IPCC GPG2003 Methodology Association of above and below ground carbon pools. Provide key category analysis approach (land use category based). Not directly applicable to the categories 5A to 5D in IPCC 1996 Guidelines. Provide decision trees.

LULUCF Sector: IPCC GPG2003 Methodology: Provides three methodological Tiers Tier 1 Employs the basic method provided in IPCC 1996 GL (Workbook) and the default EF (updated in GPG2003). It includes others land uses and pools whose emissions or removals were assumed as default ‘zero’. Tier 2 Can use the same approach as Tier 1 but applies EF and AD which are defined by the country. Can also apply stock change methodologies based on country-specific data. Tier 3 Higher order methods including models and inventory measurements.

LULUCF Sector: IPCC Software and GPG2003 Calculation of emissions using the GPG2003, in this sector, is not completely possible through the IPCC Software (it was not designed for this objective). Using the software with the IPCC 1996 GL default approach is not possible to cover all the land categories and carbon pools included in GPG2003.

LULUCF Sector: UNFCCC -NAI Software and GPG2003 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

LULUCF Sector: UNFCCC -NAI Software and GPG2003 In the current software you have the choice between two alternatives. For preparing a complete inventory it is necessary to use either of the modules, but not both.

LULUCF Sector: UNFCCC -NAI Software When you open the Module 5 you will be prompted with a dialogue box asking whether you like to use the IPCC Good Practice Format (IPCC, 2003) for the LULUCF Sector

LULUCF Sector: UNFCCC -NAI Software If you would like to use the IPCC Guidelines Format (IPCC, 1996) choose ‘NO’ in the dialogue box. Selecting “No” opens Module 5, the Land-Use Change and Forestry module as described in the Revised 1996 IPCC Guidelines.

LULUCF Sector: UNFCCC -NAI Software IPCC GPG 2003 When you open the Module 5 you will be prompted with a dialogue box asking whether you like to use the IPCC Good Practice Format (IPCC, 2003) for the LULUCF Sector

LULUCF Sector: UNFCCC -NAI Software If you would like to use the IPCC Good Practice Format (IPCC GPG, 2003) choose ‘YES’ in the dialogue box. Selecting “Yes” opens the summary table of Module 5B.

LULUCF Sector: GPG2003 The main differences introduced by the GPG2003 are the following: Inclusion of additional land categories. Inclusion of additional carbon pools. Inclusion of additional non-CO2 gases. Estimation of biomass increment and losses in each land category.

LULUCF Sector: GPG2003 Linking of biomass and soil carbon for each land category. There is no one to one linkage or correspondence between IPCC 1996 GL categories (5A to 5E) and GPG2003 land categories. Methods given for all carbon pools: AGB, BGB, dead organic matter and soil carbon and all non-CO2 gases (in IPCC 1996 GL methods were provided only for AGB and soil carbon).

LULUCF Sector: GPG2003 Worksheets and Reporting Tables The equations to estimate emissions and removals of CO2 and non-CO2 GHG from the different categories in GPG2003 are translated into new default Worksheets and Reporting Tables (designed using the same format as in the IPCC Guidelines wherever possible). Resulting estimates of emissions and removals in the Worksheets are compiled into the Compilation Worksheets and finally to the Reporting Tables.

LULUCF Sector: GPG2003 Worksheets and Reporting Tables All users using the GPG2003 should report their inventory information in the format prescribed by the Reporting Tables. Include a Tool for Estimation of Soil Carbon Stock Change.

LULUCF Sector: GPG2003 Worksheets Worksheets are presented in modules, and submodules. Each module corresponds to specific land – use category. A module is divided into two sub-modules to distinguish between those lands that remain in the same land-use category and those lands converted to other land-use categories. Each submodules consists of worksheets which are mainly grouped into four: living biomass worksheets; dead organic matter worksheets; soil worksheets (further sub-grouped into mineral and organic soils); and non-CO2 greenhouse gas emissions worksheets.

Steps Go to the sheet Summary for LULUCF and enter manually the CO2 emissions/removals from the annual change in carbon stocks (in Gg CO2) in living biomass, dead organic matter and soils for FF. Go to the Table 5Bs1 Sectoral report for LULUCF and enter manually the CO2 emissions/removals obtained for FF in the sheet Summary for the Module 5B (LULUCF) (-73396,25 Gg CO2). Make the same operation for the Summary of the inventory (Tables 7A and 7B). Note: Deliberately the results from the worksheets are not linked automatically with the summary tables because: a) In the worksheets the header are only emissions/removals whereas the summary table need to report emissions and removals separately; b) Summary Table 7B uses the structure of the 1996 GL whereas Table 5B uses the new structure. A “mapping back” is needed.
