Carbon label, which is also known as the carbon footprint label or carbon emission label, is the sum of carbon dioxide emissions generated from each stage in the life cycle of a product. Reports show that human activities increase greenhouse gas concentrations and cause global warming. Carbon-labeling schemes could fill the gap in climate policies by influencing the behavior of consumers toward the purchasing of green products. This finding indicates the significance of developing an internally applicable carbon-labeling policy before releasing international standards. Therefore, this study intends to provide an analytic network process and strength-weakness-opportunity-threat analysis approach to prioritize the carbon-labeling policy in Taiwan. Results indicate that the best policies for implementing carbon labeling in Taiwan include promotion through multiple approaches, aggressive utilization of government resources, intensive participation in international events, and extensive launch of international knowledge. In addition, this article provides guidelines and systemic decision patterns for carbon-labeling implementation to help governments and firms to develop and adjust their strategy for future carbon label implementation.
