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 6E.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 6E.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 6E.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 6E.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 6E.7


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 6E.8


Methodology: Provides three methodological TiersTier 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 6E.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 6E.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 6E.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 6E.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 6E.13


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.

IPCC 1996 GL -This submodule deals with the emissions or removals of carbon (and CO2) due to changes in forests and other woody biomass stocks affected by human activity. To calculate the net carbon uptake or release: Step 1: Estimate total biomass carbon uptake from the annual increment of biomass in plantations, forests and the growth of trees in villages, farms and urban areas (it requires data on the area of forest/biomass stocks by type, number of dispersed trees (non-forest) and the annual growth rate). Step 2: Estimate total biomass consumption from the total biomass removed in commercial harvest and the total fuelwood consumed, other wood uses and the wood removed from forest clearing (burned off site).

Note: The names of type of forest/plantations category in a country maybe different for the categories defined in the IPCC software. There are not many difficulties to change, in the software, those categories for the country-specific categories. Suggestions: 1) If the number of country specific categories is > 18, insert additional rows, the corresponding calculation formulas and links or 2) merge smaller forest/plantations categories. Only in the case that the number of categories is> 18 some difficulty arises. Remark for reporting purposes: Emission (+) and removals (-).

5B Forest and Grassland Conversion- CO2 From Biomass

5-2s1 to 5-2s2 IPCC 1996 GL -In the process of conversion: 1) some of the biomass is burned; 2) some biomass remains on the ground where it decays slowly. (The lost of carbon from soils after conversion is calculated in section 5D). To calculate the total annual CO2 release from burning and decay: Step 1: Estimate the annual loss of biomass for each forest/grassland type (information is needed on forest/grassland area converted to cropland and pasture, by type over two time periods: the inventory year and the past ten years). If figures for biomass before and after conversion are not available default values are provided.

Note: Abandoned area can also not regrowth or continue to degrade (should be ignored in this calculation). -Because regrowth rate become slower after a time, the periods considered are: 1) Land abandoned during the 20 years prior to the inventory year and 2) land abandoned between 20 and 100 years ago.

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.

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

Steps 1. 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.

2. 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.

LULUCF Sector: IPCC GPG 2003 Exercise for Self 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.

Tasks1. Determine the non – CO2 emissions using the CMNUCC-NAI software

and the IPCC GPG 2003.2. Incorporate the emissions values obtained in the Sheet ‘Summary’

from LULUCF and in the Sectoral Report Table 5B. 3. Print the used worksheet and the Sectoral Report Table.
