IPCC WGIII Fourth Assessment Report, Second Order Draft
market-pull policies in driving technical progress (it is termed
innovation on p.15, line 28).This is at the heart of the present policy
'debate' about 'technology' versus 'market-based' approaches to
climate change when both are intended to drive technical progress.
(Iain MacGill, University of NSW)
SPM-4 27 A 0 0 0 0 The sole concern of my comments is that emission taxes and
tradable emission permits should receive more balanced coverage
as possible instruments of mitigation policy. In my view the SPM
and TS currently give an impression that is biased in favour of
tradable permits, because of how they summarise the key
advantages and disadvantages of each instrument. By contrast,
Chapter 13 is more balanced.
(Jack Pezzey, Australian National University)
SPM-5 0 A 0 0 0 0 This Summary for Policy Makers needed to be the best written,
clearest and most focussed part of the Report. However, at present
it is far too long, detailed, technical, mathematical, tabular and
scholarly. There is no need for this approach, as there is a separate,
much longer, Technical Summary. Unless radically corrected it will
sharply diminish the impact of the SPM and the whole Report. As
well as conciseness and concentration on key points for decisionmaking,
the academic apparatus of references and footnotes should
be removed. If any references are deemed absolutely necessary,
they should be to the sections of the Technical Summary only. By
contrast, the 'Introduction' Chapter is a model of lucidity and
pertinence: perhaps the responsible authors could be asked to redraft
the SPM.
(Ian Cook, United Kingdom Atomic Energy Authority)
SPM-6 0 A 0 0 0 0 The main focus of the Summary is on the next fifty (or sometimes
even thirty) years. While understandable, this directs attention away
from the biggest potential problem: during the period 2050 to 2100,
most plausible stabilisation scenarios require rapid movement
towards limiting annual carbon emissions to very low levels, whilst
energy consumption continues to grow; it is unlikely that this can
be accomplished without very strong efforts to develop and deploy
