The demonstrator "umati for Data Spaces " showcases how standardized production data based on OPC UA can be used within a trusted dataspace to calculate the CO₂ footprint of products across different machine types. The resulting footprint is documented in a digital CO₂ product passport, enabling transparent and verifiable sustainability information directly linked to the manufacturing process. 

The use case focuses on enabling companies to share harmonized machine data in a secure and interoperable environment. By leveraging OPC UA Companion Specifications, the demonstrator allows live calculation of energy consumption and production-related emissions. The data is structured using OPC UA for Machine Tools (OPC 40501) and OPC UA for Energy Consumption Management (OPC 34100), and stored in the Asset Administration Shell (AAS) using the Carbon Footprint submodel. 

Machine connectivity is established via the umati Gateway, which ensures standardized data exchange from the shop floor to the dataspace. Sovereign data sharing is enabled through an EDC Connector, allowing companies to retain control over their data while participating in collaborative sustainability initiatives. 

This approach provides a practical entry point for small and medium-sized enterprises to implement permanent dataspace integration. It demonstrates how existing machines can be connected securely and how sustainability data can be generated and shared without complex infrastructure changes.
