In order to evaluate the costs and technological options by region for various targets of CO{sub 2} emission reduction, a world energy systems model was developed that spans a century and comprises 77 regional divisions. Several case studies were conducted for this evaluation using IPCC SRES A1 and B2 scenarios as baselines; and three CO{sub 2} emission stabilization targets of 650, 550 and 450 ppmv for each baseline. Further, in order to evaluate regional differences, an additional case study was conducted, reflecting the current world situation of reduction in emissions. With regard to the 550 ppmv stabilization case under the SRES B2 scenario, it was assumed that all Annex I countries except the US comply with the Kyoto target, the US achieves its target of emissions proportionate to GDP in 2010, and all the Annex I countries achieve the UK-proposal target after 2010, i.e. 61% and 77% reduction in 2050 and 2100, respectively. The analysis results also give the marginal cost of CO{sub 2} emission reduction in 2100 under the SRES B2 scenario with the emission trading at about 100, 120, and 290 $/tC for 650, 550, and 450 ppmv, respectively. However, the stabilization costs are more sensitive to the baseline; and CO{sub 2} capture and storage is important to reduce the stabilization cost; further, cost-effective technological options differ between developed and developing countries. 15 refs., 5 figs., 4 tabs.
