Presentation from September 2020 CCXG Forum

1. Common Reporting Tables
(CRTs) for GHG inventories -
Part II – Operationalising
Flexibility

2. How can Parties transparently report on the use of flexibility
within CRTs and/or the National Inventory Document (NID)?
 Deleting rows and columns would not be a transparent means of
indicating the use of flexibility
 There are many options to be explored for indicating flexibility - these
can be combined in different ways specific to particular provisions.
For example combining the use of notation keys with documentation
boxes to provide additional information in line with the provisions of
18/CMA.1
 New notation keys could be developed to differentiate between the
application of flexibility available to developing countries that need it
in light of their capacities and other types of flexibility options
available for a specific provision etc

3. How can Parties operationalise flexibility within CRTs while promoting
TACCC principles and facilitating the Technical Expert Review (TER) of
information?
 AOSIS has proposed a summary table for flexibility to be included in the BTR as follows:
Provision in
MPGs to which
flexibility has
been applied
(Heading of
MPG section
/sub-section)
How has
flexibility been
applied?
Concise
clarification of
capacity
constraints
(What other
provisions do
these capacity
constraints apply
to?)
Estimated time-
frame for
improvements in
relation to
capacity
constraints
(What is needed
to overcome
capacity
constraint/basis
for time-frame
for
improvement)
Para 29 Uncertainty

Estimate of
uncertainty for a
key category

Unavailability of

23 – tier

4. How can Parties operationalise flexibility within CRTs while promoting
TACCC principles and facilitating the Technical Expert Review (TER) of
information?
 The OECD CCXG Table 7 (option 2) lists out the provisions to which flexibility can be applied, and
Parties would then fill in whether they have or have not made use of flexibilities in each case. This
means the table is a fixed number of rows, and would be used by all Parties.
 To support such an option we would need to ensure that there are no rows missing (i.e. all
provisions for which flexibility can be used are listed).
 The advantage would be increased comparability between Parties’ reports.
 The OECD CCXG Figure 29 (option 3) shows how information on the use of flexibility could be
reported in a completeness table with information on notation keys.
 This option would not be suitable for all flexibility provisions (e.g. the application of flexibility
with respect to reporting years (provisions 57 / 58), uncertainty analysis (provision 29) and
QA/QC (provisions 34 / 35))
 Conveys less information overall
