IPCC WGIII Fourth Assessment Report, Second Order Draft
A 10 0 10 0 Table SPM-2: According to numbers here, SIGNIFICANT
reductions are possible at zero cost or net benefit. This very
important information needs to be CLEARLY highlighted in the
main text. There is a need to discuss barriers to implementing these
potential reductions. Suggest this could be done in paragraph 8
(page 8).
(Government of Environment Canada)
A 10 0 10 0 Table SPM2 is difficult to understand and thus needs a better
explanation. Can it be rendered more visually/graphically? For
instance, graphical representation of the potentials for reduction at
different costs as a portion of the projected emissions.
(Government of Environment Canada)
A 10 0 0 0 table SPM.2, comment: the figures given suggest to be accurate in
Mtons, but the summing shows they have been rounded; it is
therefore suggested to change in column 4-9, row 3, "Mton" to
"Gton", and to express all figures in columns 4-9, rows 4-48 in this
unit
(Government of The Netherlands)
A 10 0 0 0 table SPM.2, column 6-9, top row, add "for medium economic
potential"
(Government of The Netherlands)
A 10 0 10 0 Table SPM 2: second note, add text on the importance (small or
significant?) of the other gases
(Government of Finland)
A 10 0 10 0 Table SPM 2: estimate of the emissions in the Energy Supply sector
as well as All sectors are missing. Without these data the table is
incomplete as the mitigation potential doesn't mean much unless it
is compared with projected emissions.
(Government of Finland)
A 10 0 10 0 Table SPM 2: add costs at regional level for the waste sector
(Government of Finland)
