  1. UNFCCC – NAI SOFTWARE Sector: Land-Use Change and ForestryPractical Aspects and Exercises CGE Greenhouse Gas Inventory Hands-on Training Workshop

  2. CONTENT • Details on use of the UNFCCC-NAI Software to calculate and report GHG emissions in theLand Use, Land-Use Change and Forestry sector. • Practical exercises (to be solved by the participants after the presentation).

  3. BACKGROUND • The decision trees in the IPCC good practice guidance for land use, land-use change and forestry (GPG2003) 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).

  4. LUCF Sector: IPCC 1996 Guidelines Methodology Can be implemented at three different levels of complexity and geographic scale: • A simple first order approach based on aggregate default data (default approach) • More accuracy can be achieved by substituting country-specific values for general defaults.

  5. LULUCF Sector: GPG2003 Use of GPG2003 (and the higher Tiers) for GHG inventories is encouraged to reduce the uncertainty of emission estimates. GPG2003 contains good practices for the LULUCF Sector (not covered in GPG2000): • overcomes many of the problems detected in the use of the IPCC Guidelines to estimate LUCF emissions • updates information necessary for calculations(AD, EF and other emission parameters).

  6. LULUCF Sector: GPG2003 Methodology Uses the same basic conceptual approach as in the IPCC Guidelines but with some important inclusions, updates and improvements: • Provides three hierarchical Tiers of methods (nearly corresponding to the three levels of complexity of the IPCC Guidelines) • 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 converted to other land use.

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

  8. LULUCF Sector: GPG2003 Methodology: Provides three methodological Tiers Tier 1 • Employs the basic method provided in IPCC Guidelines (Workbook) and the default EF (updated in GPG2003). • It includes other 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.

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

  10. LULUCF Sector: UNFCCC-NAI Software and GPG2003 • A new module (Module 5B) has been added to the present software so that inventory compilers can apply the more recent methodologies developed by the IPCC to the Land Use, Land-Use Change and Forestry sector, as described in GPG2003. • The UNFCCC encourages the use of these methodologies, although the user may still choose to use the outdated Module 5 Land Use

  11. 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.

  12. LULUCF Sector: UNFCCC-NAI Software • When you open Module 5 you will be prompted with a dialogue box asking whether you would like to use the IPCC Good Practice Format (GPG2003) for the LULUCF Sector.

  13. LULUCF Sector: UNFCCC-NAI Software • If you would like to use the IPCC Good Practice Format (GPG2003) choose ‘YES’ in the dialogue box. Selecting ‘Yes’ opens the summary table of Module 5B.

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

  15. LULUCF Sector: GPG2003 The main differences introduced in 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.

  16. LULUCF Sector: GPG2003 • Linking of biomass and soil carbon for each land category. • There is no one-to-one linkage or correspondence between the IPCC Guidelines 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 Guidelines methods were provided only for AGB and soil carbon).

  17. LULUCF Sector: GPG2003Worksheets and Reporting Tables • The equations to estimate emissions and removals of CO2 and non-CO2 greenhouse gas 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 in the Compilation Worksheets and finally in the Reporting Tables.

  18. LULUCF Sector: GPG2003Worksheets and Reporting Tables • All users using GPG2003 should report their inventory information in the format prescribed by the Reporting Tables. • Includes a Tool for Estimation of Soil Carbon Stock Change.

  19. LULUCF Sector: GPG2003Worksheets • Worksheets are presented in modules and sub-modules. 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 category. • Each sub-module consists of worksheets, which are mainly grouped into: living biomass worksheets; dead organic matter worksheets; soil worksheets (further sub-grouped into mineral and organic soils); and non-CO2 GHG 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 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) (-2,240.15 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 headers are only emissions/removals whereas the summary tables need to report emissions and removals separately; b) Summary Table 7B uses the structure of the IPCC Guidelines whereas Table 5B uses the new structure. A “mapping back” is needed.
