Last week Centre for Sustainability and the platform Metabolism of Cities joined forces in the challenge Central Innovation District (CID) Knowledge LAB 2018. We pitched our proposal "Metabolism of Cities Hackathon" on 25 May along with 10 other teams and were one of the 5 winning teams! With this project, we make it possible to study the Urban Metabolism of The Hague by collecting and visualising data sets. It gives The Hague the possibility to get a better understanding of its sustainability performance, and The Hague will be part of an international cities project!
