IPCC WGIII Fourth Assessment Report, Second Order Draft
A 10 1 0 0 Table SPM2. This table contains very important information,
however the data sources and credibility of the data are unclear.
Further explanation with regard to how the values found in this
Table were calculated as well as how the error margins of the
calculations have been accounted for is required. These
explanations should be presented in the SPM, or as a reference in
the TS.
(Government of Japan)
A 10 1 10 50 The expansive and comprehensive caveats, which are included at
Table 11.3 need to be reflected in the SPM and the TS (at page 88
line 1) . At present none of the information explaining why Table
11.3 needs to be treated with caution is included and, therefore, a
more certain representation of cross-sectoral mitigation potentials is
provided in this table than is warranted.
(Government of Australia)
A 10 1 10 1 The description of the table should clearly state that the table is
indicative only. Suggest including "indicative" to replace
"estimated".
(Government of Australia)
A 10 1 10 50 The authors need to carefully review Table SPM 2 and Table TS 19
(page 88 line 1) to ensure that changes that are made in the body of
the text after the current review period are reflected and flow
through into this Table, as the Table could be a focus for policy
makers. Before such a table is included the authors also need to
carefully list exactly what is included in each of the sectors and
explain how different metrics in the literature are accounted for.

ACC; better explanation of
method in footnote and detail in
ch 11 and TS

DISCUSS; “indicative” may be
too vague, but care must be
taken not to suggest more
accuracy than we can justify;
careful that we are not
broadening ranges and
confidence levels so much that
the message disappears;
scrutinise the methods that were
used to calculate these
potentials
