Digital Product Passports as Information Providers for Consumers—The Case of Digital Battery Passports
研究了数字产品护照（DPP）作为新兴政策工具如何向消费者传递信息，以电动汽车电池护照为例，通过调查211名消费者识别出最有价值的属性（如预期寿命和碳足迹），并发现环境态度显著影响感知收益。
ABSTRACT Sustainable consumption is crucial to transitioning toward a more sustainable society. Various tools, including information provision tools such as ecolabels, aim to promote sustainable consumption but are often criticized for failing to adequately inform consumers. This study examines digital product passports (DPPs), an emerging policy tool, as a means of enhancing consumer communication. Given the development of battery passports, the case of DPPs for electric vehicle batteries was selected. A method incorporating elements of the self‐explicated and lead‐user approaches was used, and a survey was conducted ( n = 211) to determine which types of information provide the most value to consumers. The results identified the most relevant DPP attributes (e.g., “expected lifetime” and “CO 2 footprint”) from a consumer perspective. Groupwise comparisons based on environmental attitude and correlation analyses revealed that respondents' environmental attitudes significantly influenced their perceptions of the benefits of the investigated DPP attributes.
