IPCC WGIII Fourth Assessment Report, Second Order Draft
13 A 12 3 12 3
(Government of U.S. Department of State)
Use of "will"? rather than "could" Probably better to get across that
there is no "magic bullet" and that because energy supply is such a
huge driver of CO2 emissions, to deliver stabilisatisation at lower
levels effort will have to be placed across a portfolio of
technologies in this sector, for example ....(list). Why is the
potential for biomass particularly high? Suggest add "on existing
agricultural land" if this is so and point out that not if not. Should
comment on whether low stabilisation options can be achieved (a)
without nuclear or (b) without CCS. Certainly not possible without
either I would think.
(Rachel Warren, University of East Anglia)
13 A 12 3 12 0 Regarding, "implementation will be in the form of a portfolio of
options", revising to "implementation will need to be in the form of
a portfolio of options in order to achieve a truly sustainable energy
future in a decarbonised world" is suggested. Rationale: In

REJ; biomass point because
biomass is biggest of
renewables

bioenergy, because this will be

Point about low level
