Chapter 3. Implications of future climate regime architectures 162
For group 4 – South Asia (mainly India) and Africa – all regimes are
attractive. In particular, those where their allowable emission levels are larger
than their baseline emissions (excess emission allowances) as under the
Contraction & Convergence 2050 approach, would lead to the highest gains.
The gains of global emissions trading can provide an incentive for these non-
Annex I countries to take on quantified emission limitation commitments.
From the perspective of abatement costs, these findings lead to the overall
conclusion that the Multi-Stage, and Contraction & Convergence 2050, seem to
provide the best prospects for most Parties. However, regions in group 2 – FSU
and the Middle East – could face significantly higher costs than the other
regions, indicating that national circumstances need to be better accounted for
in the design of future regimes so as to arrive at more acceptable costs for these
regions as well.
