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 “CO2 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.

数字产品护照作为消费者的信息提供者 - 数字电池护照的案例

可持续消费对于向更可持续的社会过渡至关重要。各种工具，包括生态标签等信息提供工具，旨在促进可持续消费，但经常因未能充分告知消费者而受到批评。本研究考察了数字产品护照 （DPP），这是一种新兴的政策工具，作为加强消费者沟通的一种手段。鉴于电池护照的发展，选择了电动汽车电池的 DPP 案例。使用了一种结合了自我解释和引导用户方法元素的方法，并进行了一项调查 （n = 211） 以确定哪些类型的信息为消费者提供了最大的价值。结果从消费者的角度确定了最相关的 DPP 属性（例如，“预期寿命”和“二氧化碳足迹”）。基于环境态度和相关分析的分组比较表明，受访者的环境态度显着影响了他们对所调查的 DPP 属性的好处的看法。
