Feasibility analysis of GHG reduction target: Lessons from Taiwan's energy policy

It is the opinion of this study that more than 10 years of the United Nations Framework Convention on Climate Change (UNFCCC) negotiations have been wasted on determining the greenhouse gas (GHG) emission targets. This study discussed two approaches of GHG reduction targets: top-down approach and bottom-up. This study criticized the top-down approach for reduction target determination has created a new problem for emission reduction efforts. Using Taiwan as a case study, this study adopted the GACMO model to decompose the energy policy and analyzed the cost effectiveness of various reduction strategies. Reviewing the emission reduction measures based on the bottom-up approach is the proper way to address GHG emission reductions. Thus, the countries should refocus on implementation of reduction strategies in the spirit of the UNFCCC. Finally, this study believes that if the reduction cost curves of each nation can be made, the Bali roadmap reached through the 2007 UNFCCC COP13/MOP3 in Bali, Indonesia, can be more defined and practical.
