Through the project, we want to test whether it is possible to trace cod from sea to table. By using block chain technology, we want to create transparency in the fish value chain and thus identify important factors for sustainable purchases of fish. Helsingborg will be the first municipality in the world to use this type of technology to follow up agreed foods.


Fish is an important protein, but unfortunately the fish's path is lined with negative factors such as overfishing, by-catches, long transports and incorrect markings. 30 % of all fish sold globally is incorrectly labeled. It may not even be the same species as it says on the package. That's why transparent chains and digital documentation are so important. 80 % of all fish we buy in Helsingborg is sent 4,400 km back and forth to China to be filed. There we want to look at alternative supply chains to reduce the fish's climate footprint.


How can we in Helsingborg contribute to buying fish that have been fished and transported in a sustainable way? Through blockchain technology, you go from manual documentation to digital and can thus quickly get important information about the cod's journey. In the project, we measure, among other things, fishing method, catch zone, by-catch, slaughter method and transport. Everything will be documented in our very own "Helsingborg blockchain". By reading a QR code in our canteens, students and the elderly in our care homes will be able to obtain a lot of exciting information about the cod they will be served.

Funding for the project and collaboration takes place with the School and Leisure Administration, the Health and Care Administration and the City Management Administration.
