For four carbon-emitting sectors, the electricity, industrial, residential and commercial, and transportation sectors, this study implements the two strategies of “energy-saving and carbon-reducing measures” and “low-carbon infrastructure construction” to realize Taiwan’s low-carbon vision. The electricity sector is comprised of clean coal technologies and renewable energy resources as its main power generation structure. The industrial sector adopts the Best Available Technologies (BAT) by the International Energy Agency (IEA) to save energy and reduce carbon emissions. The residential and commercial sector implements the US Energy Star benchmark for the electrical appliances to obtain the highest energy-saving effect. The transportation sector achieves a win-win outcome for energy savings and carbon reductions with the two strategies of rail mode and electrification. With detailed data analysis and strategic planning, this study concludes that Taiwan can meet the greenhouse gas (GHG) emissions goals set by both the Sustainable Energy Policy Guidelines and the UN Intergovernmental Panel on Climate Change (IPCC) for the target year of 2030.
