ABSTRACT
This chapter takes the cost-effectiveness approach and demonstrates how it would work in practice, by analysing in some detail the costs of implementing greenhouse gas (GHG) emission-reduction projects in Zimbabwe, Botswana, Mauritius and Thailand. The case studies assessed are based on comprehensive national mitigation costing studies that have been conducted by national teams in collaboration with UNEP and ADB/UNDP for Zimbabwe, Botswana, Mauritius and Thailand. The cost assessment considers the financial and social costs of GHG emission-reduction projects based on case examples for Zimbabwe, Botswana, Mauritius and Thailand. The current assessment of financial and social costs has included a subset of the options that originally were included in the studies for Zimbabwe, Botswana, Mauritius and Thailand. The power system baseline case for Mauritius has been fuel oil-based production, while the power system baseline case has been coal-based production for Zimbabwe and Botswana, and a mix of coal and fuel oil-based power production for Thailand.
