The objective of this paper is to access the effects of the Kyoto Protocol and energy pricing policies on Taiwan's economy. Policy recommendations will be drawn from the findings. The simulation model employed is the Dynamic General Equilibrium Model of Taiwan (DGEMT). The main conclusion is as follows: The CO₂reduction policy performed very poorly in Taiwan during the past decade. If the government does not react immediately the effectiveness of the Kyoto Protocol might lead to a significant country risk for investment in Taiwan. The negative effect might reduce the economic growth rate as much as -1.57 percentage points. A progressive energy pricing policy will be useful to achieve the target of CO₂ reduction with-out significantly damaging economic growth. To avoid an overshooting effect, it is also suggested that the priority one policy be to allow energy prices to fully reflect their production cost and to reform the automobile fuel fee or road-maintenance fee from tax on cars to asx on oil products. If further CO₂ reduction is needed, a progressive carbon tax together with a package of green tax reform is then recommended.
