Major updates
Subnational disaggregation at a category level
Land Representation Manager
Higher Tiers methods in 2006 IPCC Guidelines (Vol 4)
and additional methods in Wetlands Supplement

Improvements in worksheet structure andlayout

Subnational disaggregation

Region/Geographical zone stratification allows to report at subnational level as well as tofurther disaggregate estimates according to e.g. drivers/stakeholders and/or relevantvariables

Land Representation Manager (LRM) Allows to use any of the three IPCC approaches: Approach 1 -no land use change identification Approach 2 -land use change identification Approach 3 -land use change identification and tracking across time Ensures consistency of land representation -including through fully spatially explicit
tracking of units of land-

Unit of land, an area homogenous per physical conditions -climate/vegetation zone and soil type- and current and historical socio-economic functions -land use & management typeAn excel-based tool to input at once the entire land representation is underpreparation

Regions Tab (LRM) A country can be represented in a single set of National data or in a number ofRegions
 For each Region the land representation approach is to be selectedLand Representation Tab

 A Table for each Region
 All info on land use and land use changes is to be input in this Tab
 Each unit of land is identified by a code and contains information on the current and previous landuse/management
 For each conversion, input Transition Period and Conversion Year, so the software tracks it across time Data input in the time series is to be done from its first year forward

Annual land representation matrix Tab

No data Input, just for verification (not exportable yet)Higher Tiers and additional methods
 Stock difference approach in each carbon pool of each land use
 Formulation B for SOC change in mineral soils
 When Approach 3 for land representation is applied, the software calculates
SOC net changes associated with land use/management change based on
the actual SOC content of the unit of land
 Wetlands Supplement
 Additional methods provided, identified through the use of Lilac color Additional source/sink categories, identified through the use of Lilac colorImprovements in worksheet structure and layout
 Combination of Tiers within the same set of worksheets, where the structure ofIPCC equations allows e.g. Enteric fermentation
 Addition of (set of) worksheets for each different Tier, where IPCC equations do
not allow combination of multiple tiers e.g. Gain & Loss vs Stock-Difference 492 worksheets in total available, among which the user selects those that
better deal with national circumstances.
 Such a large number allows any combinations of tiers to be composed toestimate GHG emissions from the AFOLU sector.

Tier 2 requires an energy balance -i.e. feed intake vs energy uses + manure- to estimate the fraction of energy used by enteric flora and requires
stratification of livestock populations by age, diet, productivity and husbandry system. The energy balance can be calculated through a detailed
calculation or simply derived from the dry matter intake and its quality (energy content and digestibility)

+2 for rewetted organic soil or for SOM excavation in Wetlands*for regions where Approach 1 of land representation is applied only**for management changes only*** The IPCC generic methodology [ADxEF] applies, but no IPCC default values
are provided for EF

Summary All methods in the 2006 IPCC Guidelines are implemented inthe IPCC Inventory SoftwareThus, needed flexibility to deal with any national circumstances, as per IPCC
tiered approach, is ensured

 Subnational disaggregation

Thus, tracking of specific activities/projects, and associated emission level &trend, within a national GHG inventory is allowed AFOLU sector Guidebook – version 1 under development
