IPCC WGIII Fourth Assessment Report, Second Order Draft
reductions achieved by the aluminium industry should more than
compensate for any short term increases in emissions from the
electronics sector, who too have committed to reduce their PFC
emissions.
(Robert Chase, International Aluminium Institute)
A 2 1 0 0 Fig. SPM1 seems to make light of SF6, but the case of Iceland
suggests this may be unwise.
(Michael Jefferson, World Renewable Energy Network &
Congresses)
A 2 1 1 11 In figure SPM.1, emissions from deforestation appear to be less
than 10% of total anthropogenic emissions. This is lower than most
of those usually cited in literature on this subject - eg Houghton has
recently estimated 25%.
(Government of UK)
A 2 1 2 0 fig SPM 1: use 'subscripts' in the chemical formula within the
figure and its legend
(Government of Belgium)
A 2 1 2 0 In terms of the overall trend of global greenhouse gas emissions,
greenhouse gases which are not covered by the Kyoto Protocol,
including CFCs, HCFCs and halons which are covered by the
Montreal Protocol and have considerable contribution to global
emissions, should be addressed and added to Figure SPM.1. This
would aid in understanding the objective trend. With this revision,
the sentence beginning with "Only CO2, CH4, N2O..." in the
caption of Figure SPM.1 should be removed.
(Government of Japan)
A 2 1 0 0 We propose that the denomination GtCO2-eq is written directly on
the y-axis.
(Government of Norwegian Pollution Control Authority)
A 2 1 3 10 Figure SPM.1 and figure SPM.2 do not use consistent units. The
authors should, if possible, use a common metric.
