IPCC WGIII Fourth Assessment Report, Second Order Draft
15 A 12 20 12 35
(JULIO TORRES-MARTINEZ, Cuban Observatory for Science
and Technology)
The two paragraphs on the transport sector should include
confidence readings.
(Government of Australia)
15 B 12 20 12 28 Add in a sentence about the potential of PHEVs. U.S. Government
(Government of U.S. Department of State)
15 A 12 21 12 21 This sentence expresses a widely-shared belief but is simply wrong.
The use of the "present" suggests this has been the case in recent
years. Emissions from the heat and power sector have been growing
at a faster rate than emissions from transport - for example, by
40.8% against 30.8% over 1990-2003. (IEA, 2005, CO2 emissions
from fuel combustion, OECD/IEA, Paris, p.II.75). The forthcoming
2006 edition, having corrected a number of past data, will show a
growth of 53% for heat and power against 36% for transport. The
possible argument that only end-use sectors are considered in the
AR4 is not acceptable for two good reasons: 1) IPCC reports cannot
but follow the IPCC guidelines for national greenhouse gas
inventories, where emissions from electricity and heat are
addressed exactly the same way as emissions from transport or any
end-use sector. 2) Even if one wanted to compare only end-use
sectors, then it would be necessary to allocate the emissions of the
electricity and heat sector to the various end-use sectors, mainly
industry and commercial and residential. This makes a considerable
difference in the emissions of these sectors, and thus to their growth
rates.

15 A 12 21 12 27 Reference should be made to vehicle lightweighting.
(Robert Chase, International Aluminium Institute)
15 A 12 21 12 23 Note that there are more transport technology mitigation options
but worth pointing out that the policies and measures to incentivise
sufficient and sutained investment in these technologies are not yet

team
See A-890 rejected
TIA; drop sentence on fastest
growth and focus on solutions
DISCUSS; is this a significant
message?
TIA in reformulating sentence
on fuel cell vehicles
We will include
readings of high
confidence for
both sentences.
Accepted, we
will clarify to
add the word of
end sector.
5 Accepted,we
will address fuel
efficiency.
Rejected, it is
already there.
