To reduce the impact of global warming on human living environments, the goal of achieving net-zero emissions by 2050 must be reached. Achieving this goal requires not only the development and application of low-carbon technologies and devices but also the transformation of public behaviors and lifestyles. These factors play a crucial role in reaching the net-zero target. Among the strategies to promote lifestyle changes for net-zero, one of the behavioral science methods, "nudging" has been applied across various policy areas to influence people’s behavior, showing potential for wider future application.
This study begins by gathering and summarizing literature related to behavioral science and nudging, including its theoretical foundations, applicable principles, types of strategies, and ethical considerations when applying nudging. It also collects and analyzes practices and case studies of government departments that have adopted nudging concepts, as well as international and domestic experimental low-carbon life-style cases involving nudging.
The study focuses on two specific behavioral areas: "reducing the use of single-use plastic cups" and "exchanging or trading second-hand items or clothes." Field research and stakeholder interviews have been conducted to understand the current state of public behaviors, patterns, environments, as well as barriers and cognitive biases that hinder behavior change. Based on the results, one nudging strategy experiment focused on reducing the use of single-use plastic cups has been proposed.
Subsequently, an optimized version of the nudging strategy planning guide is proposed. Optimization contents include expanding the range of information provided, adding explanations for specialized terms, and under the existing five-stage framework, outlining the key issues to consider at each stage. For the behavioral analysis phase, different international frameworks for behavior analysis is organized to help users select the appropriate analytical framework according to their specific needs. Additionally, a compilation of commonly used international nudging strategies is included to expand the range of options. A checklist is also provided to ensure that the designed strategies adhere to nudging principles. During this study, three nudging strategy promotion workshops had been held to the public. Some policy recommendations are also proposed in the last chapter.
