CanO Water is a 24-person beverage company built around aluminium cans as a plastic replacement, but it has published almost no environmental data. Claims about halving its carbon footprint through moving UK production lack numbers. No emissions targets, no water impact assessment despite being a water company, and no formal governance structure beyond founder-driven messaging.
