UNFCCC - NAI SOFTWARE Sector Land-Use Change
and ForestryPractical Aspects and Exercises

• CGE Greenhouse Gas Inventory Hands on Training
  Workshop for the African Region
• Pretoria, South Africa
• 18 22 September 2006

2
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).

3
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).
  

4
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.

5
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).

6
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.

7
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.

8
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.

9
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.

10
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

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 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

13
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.

15
LUCF Sector UNFCCC NAI Software and IPCC GL,
1996General Suggestions

• For countries using the IPCC 1996 GL.
• General Suggestions
• In the UNFCCC - NAI Software, Module 5
• Use updated AD, EF and other parameters from
  GPG2003.
• Use country-specific names/categories of
  forest/plantations.

• 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.

53

1. Linking of biomass and soil carbon for each land
   category.
2. There is no one to one linkage or correspondence
   between IPCC 1996 GL categories (5A to 5E) and
   GPG2003 land categories.
3. 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).

54
LULUCF Sector GPG2003Worksheets and Reporting
Tables

1. 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).
2. Resulting estimates of emissions and removals in
   the Worksheets are compiled into the Compilation
   Worksheets and finally to the Reporting Tables.

55
LULUCF Sector GPG2003Worksheets and Reporting

LULUCF Sector GPG2003Worksheets

• 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

• Steps
• Go to the worksheet FL -1C2 1 of 1.
• In column A enter the area of drained organic
  forest soils (ADrained) (ha).
• In column B enter the EF for CO2 from drained
  organic forest soils (EFDrainage) (ton C
  ha-1yr-1).
• In column C the software calculates the CO2
  emissions from drained organic forest soils
  ?CFFOrganic (6800 ton C yr-1).

• V) Annual change in carbon stocks in soils
  (summary worksheet)
• Steps
• Go to the worksheet FL -1C3 1 of 1 to see the
  annual change in carbon stocks in soils
  ?CFFSoils (6800 ton C yr-1).

• VI) Reporting Table for Emissions and Removals of
  CO2 and non-CO2 gases from LULUCF in the
  reporting year.
• 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.

Evaluation 5.2 Non CO2 Emissions from forest
fires (I)

• Country A Year 2000.
• Data
• The Environment Agency provided data on the
  forest area affected by fires in the country
  during the year 2000. Also the Forestry Research
  Institute provided some parameters related with
  the biomass burned during the fires.
• Tasks
• Determine the non CO2 emissions using the
  CMNUCC-NAI software and the IPCC GPG 2003.
• Incorporate the emissions values obtained in the
  Sheet Summary from LULUCF and in the Sectoral
  Report Table 5B.
• Print the used worksheet and the Sectoral Report
  Table.
