1. GDP is the most important factor for Taiwan’s CO2 emissions. Given the target of “Nuclear-free Homeland” set by the government, mitigation of CO2 emissions will be difficult for Taiwan in the future. 2. This project has evaluated five Post-Kyoto targets, including the Continuing Kyoto target, GHG Intensity target, Contraction and convergence target, Triptych approach, and Coordinated Policies and measures. The marginal mitigation cost for the GHG Intensity target is lower than the others. 3. So far as many as five international institutions have been approached in efforts to expand the current model capability. The methodology of the electricity department GHG forerunner database, established by this project, is similar to those developed by international institutions. It was suggested that the “TAIWAN-MARKAL” could be linked to those models to shape the regional GHG mitigation policies in the future. 4. The effects of carbon tax were assessed under conditions of US$48/tCO2 and US$120/tCO2. It was shown that conducting the measure of carbon tax could facilitate the entrance of advanced technologies into market. The following technologies are accelerated entering into market prior to 2020: IGCC plant with 50% efficiency, arc furnace with 20% efficiency improved, boiler with 5% efficiency improved, and heater with 7-15% efficiency improved.
