Abstract

The digital product passport (DPP) is a key pillar of the European Union’s circular economy action plan, enhancing access to sustainability information and promoting more responsible consumption. However, the challenges for inter-organizational data sharing are significant. This paper proposes a sector-wide information system architecture for Heating, Ventilation, Air Conditioning, and Refrigeration (HVAC&R), which is part of the electronics supply chain, a priority for DPP adoption. The results emerge from a systematic literature review and a field study made in collaboration with a leading HVAC&R business association. The findings show the (1) ecosystem interactions, (2) technologies, and (3) end-to-end interoperability requirements for HVAC&R DPPs. Moreover, the proposed architecture aims to design a DPP data lake for HVAC&R, thereby increasing the value of data-driven product improvement initiatives. Our work confirms that DPPs should be designed at the ecosystem level to ensure efficient data flows from the early stages of production.
