IPCC WGIII Fourth Assessment Report, Second Order Draft
2 A 4 1 4 4 We suggest to add a short description of the emission projections
for other GHGs than CO2 as given in Chapter 1 and 3. This would
be in line with the description of past emission trends on page 1
which also covered all Kyoto GHGs and the GHGs covered by the
Montreal Protocol. Suggestion: "3. Emissions of GHGs like CFCs
which are also ozone depleting and are thus covered by the
Montreal Protocol are assumed to further decline. On the contrary
non-CO2-emissions covered by the Kyoto Protocol are assumed to
increase significantly until 2050. E.g. for fluorinated gases which
are partly used as substitutes for e.g. CFCs a nearly threefold
increase compared to 2004 is expected."

SPM-44 2 B 4 1 4 5 In the case of Item A.2 of the SPM (p. 4), Chapter 1 states (p. 19)
that developing countries “will notably overtake OECD”
(Organization for Economic Cooperation and Development)
countries “as the leading contributor to global emissions in the
early 2020s,” not as late as “2030” as mentioned in the SPM item.
According to the latest data from EIA’s International Energy
Annual 2004 (preliminary data) and International Energy Outlook
2006, CO2 emissions from non-OECD countries are projected to
exceed those of OECD nations in 2014. U.S. Government

2 A 4 2 4 5 It is worth noting that having 20% of the world's population
generate 33% of the projected increase in emissions means growing
inequality in physical (tCO2eq) per-capita emissions

2 A 4 2 4 2 replace "Assuming" by "When"
(Aviel VERBRUGGEN, University of Antwerp)
2 A 4 2 0 0 Is this a statement about CO2 from fossil fuels, rather than CO2 as
a whole (which would include deforestation)? - please clarify.
