A Digital Product Passport (DPP) is being discussed as a core instrument for building a circular economy, itself a key enabler of climate neutrality. Although there is not yet a standardised, cross-sectoral and cross-company product passport system, there are already individual solutions for collecting information for certain product groups.

A DPP needs to be made available digitally for all stakeholders in order to increase transparency throughout the entire product lifecycle.

This paper answers the following questions:

• Why are politicians pushing for a DPP in connection with the circular economy?
• What is a DPP?
• What already exists?
• What does a DPP need?
• How ready are companies for a DPP? How can a DPP be delivered?
• What would a prototype look like?
