I was wondering about the legal bindingness of the refinements, will they
be part of the guidelines? Will there be recommendations, or even lessthat that?

Noted

As clearly explained in Section 1 of Overview Chapter, thisreport is to refine the 2006 IPCC Guidelines and should be
used in conjunction with the 2006 IPCC Guidelines.

Just from reading the background and overview part, maybe some
additional information could be provided to explain how the refinements
will related to the guidelines in legal terms. In addition, how do the thenupdated guidelines relate to the new guidance that will be developed by
the Meeting of the Parties to the Paris Agreement?

109110It will be fundamental to get a clear clarification and/or indication which Rocio Danica Condor
GWP countries should use for estimating GHG emissions. This is a very
Golec
important topic that needs to address since the beginning. There are many
countries that are not clear on what to use and this revision can contributeto clarify. Which are the elements for a country to choose between using
AR4 or AR5, that will help? Now many countries developing countries
are really struggegling with this item therefore good to make it clear inthis guidelines. In the 2006 Guidelines section 8.2.2 there was a clear
indication to associate with TAR. These guidelines can not leave it open
to choose one or another with no orientation.

Rejected

As clarified in Section 6 of Overview Chapter, the 2019
Refinement provides methods for estimating emissions (andremovals as appropriate) for each gas in mass units. It does notrecommend any specific metrics (e.g., GWP values) tocalculate emission estimates in CO2 equivalent units. This iscompletely consistent with the principle of 2006 IPCC
Guidelines. Section 8.2.2 in Vol.1 of 2006 Guidelines explainsthat gases covered by 2006 Guidelines are those for which
GWP values are provided in TAR, but does NOT suggest GWPvalues in TAR should be used to calculate emissions in CO2
equivalent units.

perhaps should be used could be replaced by 'shall be used' to make thelanguage mandatory? Again, the question is, how this will be read in
conjunction with the guidance under the Paris Agreement.

Petra Minnerop

RejectedIn principle, the word "shall" is not used in IPCC inventory
guidelines in order to avoid being interpreted as policyprescriptive guidance. This is completely consistent with the2006 IPCG Guidelines.

Table 1 - I personally think that the only information needed is the onethat informs you on when to use or not the guidelines. Example: the lastparagraph is enough: "update"of existing guidance means that they areencouranged… (applicable for update, elaboration and new guidance).

Rocio Danica Condor
Golec

Accepted withmodification

The explanation of the three key words ("update","elaboration" and "new guidance") will be modified.

Suggest to include here the number of the different chapters after
introducing the Volumes. Example: After Volume 1 then Chapter 1. AN
INTRODUCTION TO NATIONAL GHG INVENTORIES

Golec

Accepted withmodification

The chapter number relevant to each bullet will be added at theend of each bullet. In addition, explanation of the mappingtables will be improved. The summary of major changes
included in the Overview Chapter will be made consistent withthe mapping tables in each volume.
