Suggested ways of refinement (to be furtherexplored and decided in the scoping meeting)

Chapter 1: Introduction

1. Clarification of theconcept of“anthropogenicemissions and removals”

For the AFOLU, to extend circumstances underwhich the “Managed Land Proxy” should besupplemented with techniques to distinguishbetween anthropogenic and natural or backgroundemissions (e.g. by drawing on Guidance containedin the IPCC KP Supplement chapter 2.3.4 and 2.3.5
and the IPCC Wetlands supplement)

Chapter 2: Approaches
to Data Collection

2. Additional guidance todevelop country-specificemission factors

Indication of source categories that are moresensitive (significant) to country-specific EF (e.g.
by using UNFCCC database and EFDB)
Examples of sector specific approaches
Addition of more rationale, references andbackground information on the default parameters
used for the country-specific EF“Australia example”:
“Decision tree approach” that can be applied
on different source specific categories

4. Guidance on theintegration of GHG
emissions reported fromfacilities into national
GHG inventories

Use as a basis “TFI Technical Bulletin 1: “Use of
Facility–Specific Data in National Greenhouse Gas
Inventories”” and the “Report of the IPCC Expert
Meeting on Use of Models and Measurements in
GHG Inventories”

7. Guidance on time seriesconsistency

Disaggregation
Trend analysis in situations of large
fluctuations in emissions
Equation for trend analysis (in the cases ofsmall sources and net sources and netsinks)
Consistent definition of “significantsubcategories" across different parts of theGL (e.g. subcategories which make up 60%of the key category emissions according totheir contribution in Volume 1 and 25-30% of
the emissions of a key category in theAFOLU Volume)

Incorporate examples of country approaches (e.g.
Canada “merging of data sets from different timeperiods”, Finland “ methods for F gases”, others)
Explore if there are new methods available (e.g.
elaboration based on the guidance for AFOLU tier 3
approaches drawing on IPCC KP Supplement
chapter 2.3.)

8. Applicability of EFs overtimeAll Volumes

9. Transparency andapplicability of default EF

Suggested ways of refinement (to be further
explored and decided in the scoping meeting)

Incorporate guidance to reflect that parameters to
be used in estimation of GHG emissions/removals
need to reflect various conditions of the associatedsource/sink, such as technology used, etc. Where
such conditions change over time, it is not
appropriate to use the same default/country
specific values of emission factors and otherparameters for all years

For new emission factors to be updated ordeveloped addition of more rationale, references
and background information on the parameters
used for estimating the default EF whereinformation is available for new and existing ones(e.g. Annex 3A.3 of Wetland Supplement)
For the existing emission factors TSU to consider
prioritization, eg., TSU could find commonly used
but not well documented EF, where inventories
area highly sensitive to the emission factor used.

Refinement

1. Accessibility and userfriendliness of IPCC inventory
guidance, including backgroundinformation underlying theguidance

Suggested way of refinement (to be further explored anddecided in the scoping meeting)

Development of simpler and more user-friendly additional
supporting materials like "quick start", "primer", “ casestudies” and "cook-book" for inventory beginners
Addition of more rationale, references and backgroundinformation on the default parameters and morecalculation examples which explain how GHG emissions
should be estimated in the information boxes or separate
documents to complement the guidanceComplement to existing training material
To developed after the completion of the overall
refinements of the guidelines
To explore possibilities of interactions with otherorganizations that are developing such “cook books”

Other issues:

BOG1: Approaches to Data Collection
1. TFI/TFB/TSU to give guidance on “reporting and documentation” sections to chapter authors to ensure consistency
across the different sectors and volumes of the methodology report (Note several changes are being proposed formethodology report and will have impact in these sections)
2. FAQ to highlight that the GL can be applied for different purposes (e.g. mitigation activities) (for example REDD+ and
NAMA are not inventory activities yet countries are using IPCC guidelines for the development of mitigation activities,
therefore some guidance can be given via FAQ
3. Need to update IPCC glossary of terms
