IPCC WGIII Fourth Assessment Report, Second Order Draft

WG3 thus makes estimates of accumulated costs of mitigation,
amounting to $16 trillion, that means that WG3 has largely
increased model knowledge on mitigation measures: as for instance
illustrated in chapters 11 and 13.
B.6.:
Reference is made to Ch 3.3.5.3: Stabilization costs : uncertainties!
My, RM question: What are the basic ingredients in order to be able
to make the calculations…..
How are the costs of mitigation being determined? The presented
costs, reveal that you know the differentiated costs of the different
sets of measures. That means that you must know by and large the
type of measures to be executed and the estimated costs per
measure, per country.. This relation is important but I cannot find
that in the SPM, nor in the Chapters 11 and 13.
Now my principle suggestion is: This built-up level of IPCC
knowledge on measures must be enough to make for and with a
good selection of IPCC countries: a first set of structured mitigation
measures, ranked according to costs and effectiveness reducing
GHG emissions, related to various degrees of no-regret
experiences.
With the latter I mean:
i) Assessing large scale applications of solar PV technology which
could well be considered as a high ranked, no-regret measure for
all sunny countries, which are more or less “blessed” with
oil/gas/coal reservoirs. Legal provisions by the governments of
such countries can stimulate long term, very profitable capital
investments. The present day example is the legislative & economic
stimulating Spain, realising that PV is only 0.001 % (FAR-WG3)
of the present energy production, there is a scope for growth and
subsequent export of gained knowledge.
ii) Or, assessing : Japan and the development of Toyota Hybrid
cars not only experimental but, also at an industrial operational
scale, not only experimenting with hydrogen but also with
