IPCC Inventory Software (TSU IPCC TFI)Introduction

Goal
The guidebook for the IPCC Inventory Software (Software) is produced by the Technical Support Unit (TSU) of
the IPCC Task Force on National Greenhous Gas Inventories (TFI) to support inventory compilers in the use of
the Software for the preparation of national greenhouse gas (GHG) inventories through the description of thecomplete procedure from activity data (AD) organization and input, to emission factor (EF) selection and input,
to GHG estimation and reporting.
Software users must be familiar with the 2006 IPCC Guidelines methods and read the Software’s manual (downloadablefrom the “Help” menu) before going through this guidebook. This guidebook does not replace guidance provided
in the 2006 IPCC Guidelines.
Scope
The guidebook covers all methodological tiers and approaches provided in the 2006 IPCC Guidelines and theWetlands Supplement 1 to estimate anthropogenic GHG emissions and removals from each inventory category as wellas to deal with cross-cutting elements. Elements of the 2019 Refinement 2 are introduced in limited cases, where
needed to enable interoperability between the Software and the UNFCCC electronic reporting tool for CRT.
Structure
Inventory preparation for each category, and each associated GHG, is described in this guidebook. Each section
provides practical information to help the user enter information and estimate GHG emissions and removals forone or more categories from the 2006 IPCC Guidelines 3. Multiple categories (e.g. electricity generation and nonferrous metals) are grouped together when the underlying instructions are the same for entering information in the
Software. Table 1 below provides the definitions of various categories, as well as a hyperlink to the relevant sectionof the guidebook where further information may be found.
Each section is then presented with a parallel structure. General information on the category and gas(es) coveredis provided, along with the relevant equations from the 2006 IPCC Guidelines used to estimate GHG emission andremovals in the Software. The section then introduces the worksheet(s) contained in the Software that are to be used
to enter relevant activity data, emission factors and other parameters with a “User’s work Flowchart” to help
illustrate the user’s series of steps to enter this information. Data may be entered either within a single nation-wide
aggregate (i.e. “country name” geographical zone 4 or “unspecified”) or within a national disaggregation such asadministrative units (e.g. provinces, regions, states) or production units (e.g. companies, facilities, or any otheraggregation according to which the user collects AD). Finally, the guidebook elaborates on the relevant activity
data and emission factor input, and highlights how results are presented.
Finally, a word on selection of Tiers:
The Software provides functionalities -calculation worksheets and data managers- to prepare estimates according to
any of the methodological tiers for which IPCC provides equations. Thus, in this Guidebook the following
definitions are used to indicate the methodological tier of the relevant equations, and the correspondence withtiers in an NGHGI:IPCC Tier 1 refers to the IPCC Tier 1 equations and default EFs/parameters.
Furthermore, recognizing that the 2006 IPCC Guidelines allow reporting estimates produced with a Tier 3 userspecific 5 methodology, Tier 1 equations can be used to enter AD and Implied Emission Factor(s), as calculated by
dividing the Tier-3 estimated GHG emission with the underlying AD required by the IPCC Tier 1 equation(s), to
reproduce the estimated Tier 3 emissions.
IPCC Tier 2 refers:
 either to the IPCC Tier 2 equations, with IPCC default values or user-specific EFs/parameters, different from
IPCC Tier 1 equations in the level of stratification and/or in the variables/parameters; or, when a Tier 2 Equation is not provided, to the IPCC Tier 1 equation and user-specific EFs/parameters (e.g.
category 1.A.3.d water-borne navigation).
1 Elements derived from the Wetlands Supplement are clearly distinguishable because of the liliac colour used to mark those.
2 Elements derived from the 2019 Refinement are clearly distinguishable because of magenta colour used to mark those.
3 In few instances, denoted by magenta colour, from the 2019 Refinement.

4 Please note that in other categories the sub-national stratification has been implemented within subdivisions while for category 3.A it has
been implemented within geographical zones .
5 User-specific methodologies need anyhow to be accordant with IPCC good practice to satisfy the Transparency, Completeness, Consistency,
Accuracy and thus Comparability reporting principles.

4|PageLivestock Users’ Guidebook

IPCC Inventory Software (TSU IPCC TFI)IPCC Tier 3 is the IPCC methodology different in the level of stratification and/or in the variables/parameters,from the IPCC Tier 1 and Tier 2 methodologies.
Tips
Stratification 6 of variables 7 used to calculate GHG emissions according to IPCC methodologies is a key element
to promote accuracy and precision of estimates. Thus, the Software allows an unlimited input of elements for eachof the variables and allows any combination of those.
Stratification is actually implemented in a two-way, by subdividing the entire category, in segments (geographicalzones) and applying a single methodological tier, or subdividing the category in segments and applying different
methodological tiers to different segments. Which means that within a category, those segments for which data
are available -e.g. a specific technology for which EFs are known- are singled out 8 while all remaining are reported
within a single aggregation 9, as e.g. unspecified 10.
However, the Software allows to enter each combination of variables, e.g. geographical zone/livestockcategory/subcategory/subdivision/MMS, only once. A way to further disaggregate such a combination across timeseries is through using e.g. the MMS name with a time-prefix. For instance, where the emission rate of an MMS
changes across time, the addition of a prefix that indicates the MMS before and after a certain date where thechange in the emission rate occurred, allows the user to implement such technological evolution within the current
structure of stratification of the variables (e.g. pre-year Y and post-year Y MMS X).
Often worksheets have sub-layers that the user shall access to enter data. To do so, click on the element⊞ on the left-hand side of worksheet. Once clicked the element ⊞ changes to ⊟.
Interoperability with the UNFCCC electronic reporting tool for the Common Reporting Tables (CRT)The Software has been upgraded to be interoperable with the United Nations Framework Convention on Climate
Change (UNFCCC) electronic reporting tool for the Common Reporting Tables (CRT) under the Enhanced
Transparency Framework of the Paris Agreement. 11 In practice, that means that users of the Software can estimate
GHG emissions and CO2 removals for categories and gases that are required to be reported pursuant to the
UNFCCC CRT. Once data are entered into the Software, users wishing to use these data to facilitate reporting to
the UNFCCC must generate a file in the Software (in JSON format) that may then subsequently, through a separate
UNFCCC platform, be uploaded and further processed through the UNFCCC electronic reporting tool for CRT.
A separate Guidebook, titled IPCC Inventory Software: UNFCCC Interoperability- CRT Export Quick Start
Guide, has been developed to assist users in generating the JSON file for upload to the UNFCCC electronic
reporting tool for CRT. Annex I illustrates the mapping of activity data and GHG estimates for categories/gases
from the Software to the corresponding UNFCCC CRT category/ies.

6 The larger the number of strata, the more accurate and precise the estimates are.
7 Stratification is the act of sorting data into distinct groups or layers.
8 By applying a higher tier method
9 By applying a lower tier method

10 This does not apply to variables required by IPCC Tier 1 method.

11 As requested by Parties in decision 5/CMA.3, paragraphs 19 and 20.

Agriculture, Forestry and Other Land Use (AFOLU) Sector

The Agriculture, Forestry and Other Land Use (AFOLU) Sector integrates the previously separated Agriculture andLand Use, Land-Use Change and Forestry sectors. This integration recognizes that the processes underlying greenhousegas emissions and removals, as well as the different forms of terrestrial carbon stocks, can occur across all typesof land and that often the same practices influence both Agriculture and Land Use, Land Use Change and Forestry.
This approach is intended to improve consistency and completeness in the estimation and reporting of greenhousegas emissions and removals.
This Guidebook is limited to categories in the Software exclusively related to livestock, i.e. 3.A.1 - EntericFermentation, 3.A.2 - Manure Management, 3.C.6 - Indirect N2O emissions from manure management.

GeneralII.1.1

Use of multiple tiers for reporting

IPCC Inventory Software (TSU IPCC TFI)The 2006 IPCC Guidelines provide methodological guidance to estimate anthropogenic GHG emissions andremovals according to three methodological tier levels: Tier 1, Tier 2, Tier 3. Where Tier 1 is the common default
methodological approach that the IPCC Guidelines provide to all inventory compilers, higher tiers are based onuser-specific and multivariable-dependent rates of GHG emissions and CO2 removals, and likely requires data witha higher spatial and temporal resolution. Tier 2 may apply a different methodological approach, or the Tier 1
methodology approach with user-specific values for parameters and EFs, and may further disaggregate thepopulation of activity data to apply condition-specific values of parameters and EFs 13. Tier 3 is generally 14 a userspecific methodology that maintain consistency with IPCC good practice, although it is designed to better cope withthe user-specific statistical population for which GHG emissions/removals are estimated or it is based on the
direct monitoring of the source of GHG emissions.
Given that the Software can calculate GHG emissions and removals for each source/sink category using any of themethodological tiers provided in the 2006 IPCC Guidelines and its Wetlands Supplement, the user may apply a single
methodological tier to the entire category or may use instead a combination of different tiers according to thesignificance of subcategories and data availability.
In doing so the user shall transparently describe in any accompanying inventory report the original methodology
and the way it has derived the implied EF.
While, as described above, the user may use a combination of tiers within a single source category, it may also wish
to apply multiple tiers to the same activity as a means of quality control through comparative analysis (e.g. Tier 1
vs Tier 2 or Tier 2 vs Tier 3). Although this is a legitimate use of the Software, those comparative analysis shall bedone in a separate database not used for reporting the GHG inventory, so avoiding to double count GHG
emissions from a source.
Where a user-specific Tier 3 method, which cannot be calculated by the Software, is used to prepare estimates of
GHG emissions that need to be included in the NGHGI for completeness, the user can use the relevant calculation
worksheet(s) to report it as it follows:
1. enter in the Software the AD required by the IPCC default methodology.
2. back-calculate CO2 and/or CH4 and/or N2O IEFs 15, as the total emissions of the relevant GHG calculated
through the user-specific Tier 3 method divided by the AD required at bullet 1 above, and enter those in the
Software.
3. the Software then reproduces the user-specific Tier 3 GHG estimates.
A dedicated geographical zone could be entered, e.g. specifically titled as “Tier 3” with any other identifying
information, as appropriate.

13 For example, the Tier 2 approach for CH4 emissions from Manure management requires to calculate the Volatile Solid excretion rate toestimate the EF.

14 In some cases, IPCC also provides a Tier 3 methodology, as for instance for CH4 and N2O emissions from Road transportation, although

this is not the case for source-categories considered in this Guidebook.

II.1.2IPCC Inventory Software (TSU IPCC TFI)

Reporting of Subdivisions

GHG inventories can be calculated at multiple levels of aggregation (e.g. farm, companies, regional, national) tomeet various domestic and international needs. Thus, Geographical zones can be entered for all source categories inthe Livestock-related categories (3.A, 3.C.6) in the AFOLU sector.
Where the user is interested in calculating GHG estimates at a single level of aggregation, e.g. national, in Column|S| either unspecified is to be selected from the dropdown menu or the single univocal name/code is to be enterede.g. the country name. Where the user is interested in calculating GHG estimates for multiple geographical zones,
the univocal name/code for each geographical zone will be entered in Column |S|, users have full flexibility toname those geographical zones based on user-specific circumstances. Nevertheless, care shall be taken to ensurethat s geographical zones do not overlap so causing a double counting of some emissions.
Every calculation worksheet 16 includes filters to enable the user to view data entry, by subdivision.
Example: geographical zones

Example: visualizing filtered results

“Uncertainty” and “Time Series data entry”

To enter data on Uncertainties or to enter Time Series data, calculation worksheets have dedicated tabs that can beaccessed through buttons placed either at the lower right-hand side or next to the Fuel type button. Users areprompted to learn about how to use these functionalities in the User Manual of the Software (accessible at Help tab).
Time series data entry:
In each worksheet, there is a button “Time Series data entry” as shown in the screenshot below.

To use this functionality then users:
1. Select in TAB Application, sub-TAB Inventory Year, the time-period of the inventory:

and click on button Apply to save it.
2. select parameters for which the user wants to upload a time series of data from the Parameters bar. This list ofparameters (e.g. consumption, conversion factors, EFs, etc.) depend on variables contained in the specificworksheet.
3. press the button Export to Excel, name the file and export it.
4. open exported file and for the entire time series, or for any fraction of it, enters data or make changes to data
already present.
5. once data are compiled, the file is imported back into the Software by clicking the button Import from Excel.

II.1.4IPCC Inventory Software (TSU IPCC TFI)

Livestock

Livestock emits CO2, CH4 and N2O. However, CO2 emissions from livestock are not estimated because annual
net CO2 emissions are assumed to balance to zero – i.e. the CO2 photosynthesized by feed plants in annual biomass,
which is not counted in the land categories, is returned to the atmosphere as respired CO2 by the animals within
the year.
Livestock manure management is a source of CH4 emissions, likely substantial when manure is managed in a liquid
form, and N2O emissions, especially relevant when manure is managed in a solid form.
Unlike, IPCC default methodology (Tier 1) that requires a basic characterisation of livestock populations, IPCC
Tier 2 requires an enhanced characterisation by sex-age-purpose in subcategories (e.g. beef cows) and, if data
permits, in subdivisions (e.g. further stratified by age/ purpose/diet).
Livestock characterisation, to be entered in the Livestock Manager, is the first step when preparing GHG
estimates of livestock-related categories i.e. 3.A.1 - Enteric Fermentation - CH4, 3.A.2 - Manure Management,
3.C.6 - Indirect N2O emissions from Manure Management.

IPCC Inventory Software (TSU IPCC TFI)

Livestock Manager

The Livestock manager aims at stratifying the livestock in more homogeneous subpopulations. It is composed bythree TABs where users are required to enter information on:
1. the Geographical Zones, of which the territory inventoried is composed. Users can enter a number ofgeographical zones or just a single one only. This information is used by the sofwtare to assign a default CH4
EF value 17 or a default Methane Conversion Factor value for emissions from Manure Management; andanyhow allows the user to stratify its inventory with different populations to which applying different
methodological tier level according to data availability.
2. the Livestock Characterisation, requires users to enter a characterisation for each livestock population. The
Characterisation users enter can be an IPCC basic or an IPCC enhanced or a User-specific or a combination of all of,or any of, those options. The Software then populates livestock-related calculation worksheets according to thelivestock sub-categories/subdivisions entered in the Livestock Characterisation. A single Characterisation applies toall geographical zones.
3. the Manure Management System, requires users to select among IPCC default MMSs those to be applied in
the inventory as well as to input any additional user-specific MMS. A single MMSs Selection applies to all
geographical zones and all livestock populations.
Note: Information is to be entered in the Livestock Manager only once (in any inventory year) and applies to all
livestock related categories:
Note: Information input the Livestock Manager can be thereafter modified, although the deletion of any
information previously entered likely causes losses of data in the Livestock-related calculation worksheets where
the information deleted was applied.

17 2019 Refinement stratifies it according to IPCC Climate Zones instead.

III.1 Geographical Zones
In this TAB, users:
a. Enter geographical zones (entire country may be reported under a single zone);b. Select from drop-down menu average annual temperature (AAT) relevant to each geographical zone;
Note: Information on Geographical Zones is to be entered only once (in any inventory year)
Example of data input, a user enters 4 geographical zones: Rangeland, Intensive Livestock farming, Rural Livestock
farming, Coastal prairies, with the following characteristics:
 Rangeland, natural grassland on highlands (cool climate, AAT of 14°C) extensively grazed, with manure left on
pasture MMS = Pasture/Range/Paddock); Intensive livestock farming, farms in lowlands (temperate climate, AAT of 20°C) with high-productive husbandrysystems, with a number of MMS specific of the different livestock populations; Rural livestock farming, farms in lowlands (temperate climate, AAT of 20°C) with low-productive husbandrysystems, with a number of MMS specific of the different livestock populations; Coastal land, improved grazed coastal grasslands (warm climate, AAT of 26°C) with low-productive husbandrysystems, with manure left on pasture MMS = Pasture/Range/Paddock:Note that: same livestock population alternates between Rangeland and Coastal land (6 months each)

Recall: enter information in the row with the asterisk on the left-hand side -i.e the bottom-most row- to add eachgeographical zone with its information.
Recall: name and AAT of a geographical zone can be re-entered without data loss in the calculation worksheet.
However, where the ATT is re-entered, IPCC default CH4 EF value for Manure Management may need to be reentered given it is temperature-dependent, where not re-entered the sofwtare keeps the value previously entered.
Recall: click on button SAVE before closing the TAB, otherwise information entered will be lost.

In this TAB, users enter any additional user-specific MMS at the bottom of the list.
Only those MMS that are listed in this TAB will be available for use in livestock-related calculation worksheets.
In the example below an additional MMS has been entered: covered anaerobic lagoon, with its description 20 -to enter a
description of the MMS is very important to be sure you recall its characteristics, as well as to ensure that otherusers are informed about it.
Note: Information on Manure Management Systems is to be entered only once (in any inventory year)
Recall: enter additional MMS in the row with the asterisk on the left-hand side -i.e. the bottom-most row- 1 row foreach additional MMS;
 click on button SAVE before closing the TAB, otherwise information entered will be lost.

Livestock

The Software allows to calculate livestock emissions according to three methodological approaches: IPCC Default (Tier 1) for every livestock population, based on activity data by emission factor
 IPCC Tier 2 (IPCC Tier 2 – Simplified) for every livestock population, based on dry matter intake; IPCC Tier 2 (IPCC Tier 2 – Detailed) for cattle/buffalo and sheep only, based on gross energy need 21;
Once entered data required in Livestock Manager, second step to calculate emissions from livestock is thecompilation of information in Livestock Population worksheets for both 3.A.1 - Enteric Fermentation – CH4
and 3.A.2 – Manure Management and indirectly for category 3.C.6 - Indirect N2O emissions from Manure
Management.

Livestock Population (3.A.1 & 3.A.2)

Allows to select the tier level and to input annual average population data for each animal subdivision. In addition,
where one of the two IPCC Tier 2 levels (Detailed or Simplified) is selected, the worksheet allows to input allparameters used to estimate average daily gross energy intake.
Guidance on data collection and analysis for livestock population characterisation is provided in Section 10.2.
Note: Information input in Livestock Population worksheet of category 3.A.1 (Enteric Fermentation) areautomatically transferred in Livestock Population worksheet of category 3.A.2 (Manure Management) and viceversa.
Calculation worksheet Livestock Population requires users to select the methodological tier level to be applied to therelevant livestock population and to enter the annual average population and the typical animal mass of such population.
Depending on the livestock population and associated methodological tier level selected users enter required
parameters to calculate the daily gross energy intake.
Methodological tier level selection is operated in Column |Method| by selecting the desired methodological tierlevel from the dropdown menu:
selecting the methodological tier level (example from Dairy Cows livestock category)In particular:
All livestock species all methodological tier levels
IPCC Tier 1 (IPCC Default)
1. Column |Z|: Select Geographical zone from dropdown menu 22;
2. Column |Tsc|: Select Livestock Subcategory from dropdown menu 23. If no subcategory has been entered in
Livestock Characterisation TAB of the relevant animal species, select Unspecified;
3. Column |Tsd|: Select Livestock Subdivision from dropdown menu 24. If no subcategory has been entered in
Livestock Characterisation TAB of the relevant animal species, select Unspecified;
4. Column |AAP|: Select either Specified or Calculated (Eq. 10.1) for Annual Average Population 25 (AAP), heads.
Thus: Specified, enter heads value in Column |N(T)|

22 The dropdown menu contains all Geographical zones entered in Geographical Zones TAB.

23 The dropdown menu contains all subcategories entered in Livestock Characterisation TAB of the relevant animal species.
24 The dropdown menu contains all subcategories entered in Livestock Characterisation TAB of the relevant animal species.

25 Where possible, inventory compilers use population data from official national statistics, including statistics reported by country to the
Food and Agriculture Organisation (FAO) and stored in its FAOSTAT.
Seasonal births or slaughters may cause the population size to expand or contract at different times of the year which will require thepopulation numbers to be adjusted accordingly.
E.g. broiler chickens are typically grown approximately 60 days before slaughter. Estimating N(T) as the number of grown and slaughteredover the course of a year would greatly overestimate the population, as it would assume each lived the equivalent of 365 days. Instead, one
should estimate the average annual population as the number of animals grown divided by the number of growing cycles per year. For
example, if broiler chickens are typically grown in flocks for 60 days, an operation could turn over approximately 6 flocks of chickens overthe period of one year. Therefore, if the operation grew 60,000 chickens in a year, their average annual population would be 9,863 chickens.
For this example the equation would be: Annual average population = 60 days * 60,000 / 365 days / yr = 9,863 chickens
Further, in a growing or decreasing population most animals are alive for only part of a complete year, although their contribution shall be
included in the Annual Average Population, regardless of were slaughtered or die of natural causes. Also in this case the application of Equation
10.1 allows to calculate the correct value, in heads, to be entered as Annual Average Population.

26 Calculation of the AAP applies also to populations that stay within a subcategory/subdivision for a portion of the year only while moving
to other subcategory(ies)/subdivision(s) for the remaining portion. For instance, a population of X heads of Mature Ewe spends 4 months
in highland rangeland and the rest of the year in lowland pastures. So, the population can be split in 2 subpopulations, e.g. Rangeland vs

𝑋𝑋

𝑋𝑋

and
respectively. Where one of the two phases occurs outside of the
Pasture, and the AAP for the 2 subpopulation calculates as120
245
geographical boundaries of the inventory -e.g. the lowland pasture is in another country- reporting will be limited to the subpopulation
within the geographical boundaries of the inventory -e.g. the highland rangeland-.
27 Page 10.24 - One approach for developing an approximate emission factor is to use the IPCC Default CH4 emissions factor for EntericFermentation from an animal with a similar digestive system and to scale it using the ratio of the weights of the animals raised to the 0.75
power.
28 Feed digestibility (DE%) - Table 10.2 - is the portion of gross energy (GE) in the feed not excreted in the faeces, and it has to be expressedas the percentage (%) of GE or DMI

Manure Management – CH4

Information
The decomposition of manure under anaerobic conditions (i.e., in the absence of oxygen), during storage andtreatment, produces CH4. These conditions occur most readily when large numbers of animals are managed in aconfined area (e.g., dairy farms, beef feedlots, and swine and poultry farms), and where manure is disposed of inliquid-based systems.
IPCC Equations
CH4 emissions are estimated by applying the following IPCC equations: IPCC Default (Tier 1): Equation 10.22
 IPCC Tier 2 Detailed: Equations 10.22, 10.23, 10.24, additional species-specific equations 10.2 - .16

Information
Indirect emissions result from volatile nitrogen losses that occur primarily in the forms of NH3 and NOX. N isalso lost through runoff and leaching into soils from the solid storage of manure at outdoor areas, in feedlots andwhere animals are grazing in pastures 69.
To estimate Indirect N2O emissions from Manure Management users SHALL first estimate Direct N2Oemissions from Manure Management.
IPCC Equations
Indirect N2O emissions are estimated by applying the following IPCC equations: IPCC (Default) Tier 1: Equations 10.26 & 10.27 limited to indirect N2O emissions from N volatilization;
 IPCC Tier 2: Equations 10.28 & 10.29, limited to indirect N2O emissions from N leaching/runoff.
As explained in section II.1.1 - Use of multiple tiers for reporting, GHG estimates prepared with user-specificTier 3 methods can be reported in the Software worksheets that implement IPCC Default (Tier 1) equation.
Software Worksheets
The Software calculates Indirect N2O emissions using worksheets: Livestock Manager: contains data on stratification of the livestock population by geographical boundaries,
species, subcategories, subdivisions, as well as on manure management systems utilized in the NGHGI.
 Livestock Population: contains for each subcategory/subdivision combination, the amount of the populationand the typical animal mass, as well as a number of parameters for IPCC Tier 2 methodology to calculate theenergy needs of animals.
 Average Daily Feed Intake: depending on the methodological tier selected calculates energy needs for eachsubcategory/subdivision combination.
 MMS Usage: contains for each subcategory/subdivision combination, MMSs used and the fraction of manure
applied to each MMS.
 N excretion rate: contains Nexcretion rate for each subcategory/subdivision combination, where IPCC default
method is selected.
 N excretion rate - Tier 2: calculates Nexcretion rates based on N inputs (percent of crude protein in diet) and N
needs for each subcategory/subdivision combination, where IPCC Tier 2 method is selected.
All above worksheets are used to first estimate category 3.A.2 - Direct N2O emissions from Manure
Management
 Manure N loss due to volatilisation: calculates the amount of manure N loss due to volatilisation for eachcombination of geographical zone/MMS/livestock 70 and associated total N excreted.
 Manure N loss due to leaching/runoff: calculates the amount of manure N loss due to leaching/runoff foreach combination of geographical zone/MMS/livestock 71 and associated total N excreted. IPCC Tier 2 only.
 Indirect N2O emissions due to N volatilisation from Manure Management: calculates indirect N2Oemissions due to N volatilisation from Manure Management, in mass units (Gg), for each geographical zone.
In addition total emissions are calculated.
 Indirect N2O emissions due to N leaching/runoff from Manure Management: calculates indirect N2Oemissions due to N leaching/runoff from Manure Management, in mass units (Gg), for each geographical zone.
In addition total emissions are calculated.

69 Indirect N2O emissions from leaching and runoff of N from pastures, range and paddock are instead reported under category 3.C.5 –Indirect N2O emissions from managed soils.

IPCC Inventory Software (TSU IPCC TFI)

Annex I: Mapping between the IPCC Inventory Software and the
UNFCCC ETF Reporting Tool
The Software enables users to calculate national GHG emissions in accordance with the 2006 IPCC Guidelines. The
methods contained in the Software are consistent with those required to be used by Parties in preparing a national
GHG inventory, consistent with decision 18/CMA.1, under the Enhanced Transparency Framework (ETF) of theParis Agreement. However, Parties to the UNFCCC have agreed to a specific format for reporting the GHG
inventory information, called the common reporting tables (CRT), that differ from the IPCC reporting tables
contained in volume 1, chapter 8 of the 2006 IPCC Guidelines.
Thus, Parties to the UNFCCC, acknowledging the importance of the Software in aiding countries to estimate theirnational GHG inventory, have invited IPCC to work together to facilitate interoperability between the Software andthe UNFCCC electronic reporting tool. Consequently, the Software has been upgraded to operationalize theinteroperability. Specifically, users of the Software can estimate GHG emissions and removals for all categories andgases that are required to be reported pursuant to the CRT. Once data are entered into the Software, users wishingto use these data to facilitate reporting to the UNFCCC must generate a file in the Software (in JSON format). Thisfile, can then subsequently, through a separate UNFCCC platform, be uploaded and further processed throughthe UNFCCC electronic reporting tool to transfer to UNFCCC their national GHG inventory, as compiled in the
CRTs and as required under the Paris Agreement.
Preparing a JSON file that can be imported into the UNFCCC electronic reporting tool required a cell-by-cell
mapping of the CRT to document where each of the AD and GHG emissions estimates contained in each
worksheet of the Software reside in the CRT.
This annex contains detailed information to illustrate the mapping of data on livestock-related categories -i.e. 3.A.1- Enteric Fermentation, 3.A.2 - Manure Management, 3.C.6 - Indirect N2O emissions from manure
management- between the Software and the CRTs. The specific information presented in this annex related toreporting of emissions from livestock-related categories in the CRT is supplemental to the general information
provided in the IPCC Inventory Software -UNFCCC Interoperability – CRT Export Quick Start Guide.

The mapping between the Software and the CRT are visualized in the Software to allow the user to properly
understand, and keep for internal use, the results of the conversion of IPCC category GHG estimates into
UNFCCC NGHGI categories, thus enhancing transparency.
To generate the visualization tables, select from the ribbon “Export/Import” and then “UNFCCC CRT” togenerate the tables. For complete guidance on how to do this, refer to the IPCC Inventory Software -UNFCCC
Interoperability – CRT Export Quick Start Guide. The result of the generated tables is presented in Table

IMPORTANT: these visualization tables have been prepared to enhance transparency and demonstrate to theuser how the data entered in the Software are mapped to the UNFCCC CRT. The data entered in the Software are
not automatically used to meet the UNFCCC reporting requirements. The user will still be required to formallysubmit the information through the UNFCCC electronic reporting tool for CRT, and the user is responsible forreviewing first the information compiled in the CRT visualization tables, and second the information once
imported into that tool.

Livestock Users’ Guidebook

IPCC Inventory Software (TSU IPCC TFI)How to read mapping tables
The mapping tables have been developed to enhance transparency of the relationship between the categories in
the Software and the UNFCCC reporting tool for CRT. For each cell in the CRT, the mapping tables describe thesource of the data from the Software that is reported in that cell. The majority of cells in the CRT map from theunderlying category-specific worksheets of the Software. In limited cases (e.g. for some short-lived climate forcer
emissions in the sector summary tables) data are mapped from the IPCC background or sectoral reporting tables.
The specific mapping instructions vary, depending on the nature of the category, and how many calculation
worksheets from the Software map to that cell, but generally, the instruction is written to direct the user to:
1. The specific IPCC category in the category tree
2. The tab in that worksheet that contains the relevant information; in the case of the reporting of livestock
emissions in CRT tables 3.A, 3.B(a) and 3.B(b), reference in the mapping is often made to one of the three tabsof the Livestock Manager: Geographical zones, Livestock Characterisation and Manure Management System
3. The relevant livestock category(categories) when a single worksheet includes multiple livestock type
4. The column that contains the relevant information, with an indication of any mathematical operation needed(e.g. SUM, MULTIPLY BY, etc)
5. Any conversions needed to ensure correct units map to the UNFCCC CRT (e.g. DIVIDE by 1,000 to convert
Population to Population (1,000s)).
By illustration, the directions in the mapping file to report total CH4 emissions from manure management of sheepin the CRT, and the corresponding location of the information in the Software are shown below in Table A.1.4. The
user would refer to category 3.A.2.c in the Software, which refers to manure management of sheep, and then theworksheet for CH4 emissions from manure management. You will see that mapping file includes the total sum of
the column “CH4”, this is because the CH4 emissions from all types of sheep will map to the single cell in the CRT.
Generally, white cells in the CRT are mapped from the Software. Orange, green, or blue cells in the visualized CRT
in the Software will be calculated by the UNFCCC electronic reporting tool for CRT, upon import of the JSON file.

The example above is a simple illustration. In some cases, multiple worksheets and even multiple categories may
map to a single cell in the CRT. This would be illustrated by reference to the two key instructions “PLUS” or“AND” to denote consideration of multiple data elements from the Software.
The following recurrent key instructions in the mapping are:
 The sign "SUM" indicates a summatory of information (numerical or alphabetical) contained across thecolumn/row to which applies.
 The sign "-SUM" indicates that the result of the summatory is to be reported as a negative value.
 The sign "AND" indicates an additional element for mapping in the cell, which pertains to the same IPCC
category.
 The sign "PLUS" indicates an additional element for mapping in the cell, which pertains to an additional IPCC
category.
 The signs "MINUS" indicates an additional element for mapping in the cell, which information pertains to adifferent IPCC category and it is to be subtracted.
 The signs "EXCEPT" indicates an element for mapping to be excluded because this element (e.g. fuel or
IPCC category) is already included elsewhere.
 The signs "MULTIPLY" and "DIVIDE" and "SUBTRACT" indicate the corresponding mathematicaloperation to be applied to information sourced from the Software.
 The signs "ISNOT" means ≠.

IPCC Inventory Software (TSU IPCC TFI)

There are two unique elements for the mapping of livestock that are relevant to highlight:
1. The basic characterization versus an enhanced characterization for cattle. As explained in Table A.1.1,
the CRT allows two, mutually exclusive options for reporting of cattle emissions: Option A, divided between
Dairy cattle and Non-dairy cattle (i.e. a basic characterization), and Option B, divided among Mature dairy cattle,
Growing cattle, Other mature cattle, and Other (please specify) (i.e. an enhanced characterization). If you do not have
any livestock subcategories for cattle entered in the Livestock Manager, all cattle will map to Option A, with
Option B reported as “NA” (not applicable). Alternatively, if you have a livestock subcategory under either
Dairy Cows or Other Cattle in the Livestock Manager, your data will map to Option B, with Option A reported
as “NA”.
2. CRT tables 3.A and 3.B also include a section to enter “Additional information” in cases where Tier 2
is used. The additional information for table 3.A will be completed when relevant information is entered into
the Software, even with a basic characterization (i.e. no livestock subcategories entered in the Livestock
Manager under either Dairy Cows or Other Cattle). Additional information for CRT table 3.B(a) will only becompleted with relevant information when an enhanced characterization is entered (i.e. a livestock subcategory
is entered into the Livestock Manager) and the corresponding worksheets for IPCC category 3.A.1 and 3.A.2
designate the use of a Tier 2 (Simplified) or Tier 2 (Detailed) in the column Method. An example worksheet isshown in Figure A.1.1 below and a flowchart provided in Figure A.1.2.

3. Data input in the Livestock Manager will influence where data are mapped to the CRT. In addition to
the use of the Livestock Manager to identify, and subsequently map the livestock types in the country, theannual average temperature for each geographic zone and the manure management system(s) entered into theLivestock Manager are referenced when completing the worksheets (e.g, for the additional information tablefor CRT table 3.B(a)).
Table A.1.5 below demonstrates an example where a livestock subcategory under cattle is added into the Livestock
characterisation tab of the Livestock Manager, and thus reporting is for Option B. The instructions then refer the
mapping to the “MMS Usage tab of IPCC category 3.A.2.a.i. The geographic zones included in this cell are only
those in cool temperatures (as defined in the Geographic Zones tab of the Livestock Manager), and the calculationis referring to the fraction of livestock in those zones as a fraction of total livestock handled in anaerobic lagoons.
