Industrial data spaces are indispensable for sharing confidential data with a clearly defined number of users, such as your own suppliers. Companies can use them, for example, to precisely calculate the carbon footprint of products along the supply chain, share manufacturing documentation, create digital product passports, and efficiently identify disruptions in value chains. The data space defines both the rules of the game that must apply to all users and the basic technical infrastructure for uncomplicated data usage. Pilot projects such as Catena-X and the Manufacturing-X initiative are carrying out research regarding the necessary technologies and governance structures in this context.
