C-PRONE kicked off its first public activity, connecting with the Circular Cities and Regions Initiative (CCRI) order to exchange experiences and identify opportunities for collaboration. Led by ACR+ and Rijkswaterstaat, the discussion focused on behavioural change in organisations, as both initiatives identified it as a key challenge to scale up circular practices. To enrich the discussion, the Interreg Europe Circular Minds project was invited to present the Framework that is being developed on the topic. The inputs provided by participants will be integrated in the Framework, and after being tested by project partners, it will be an availablefor organisations as a tool to determine shifts in mindsets.
