For the first time, 30 March will mark the International Day of Zero waste. In this context, the Geneva Environment Network organizes the discussion "Beating Waste Pollution | Geneva Zero Waste Day Celebration." This multi-stakeholder event will highlight the steps taken by International Geneva actors and beyond to achieve the zero waste agenda. While the tide is out, those brave volunteers struggle in the mud to collect rubbish and loads of plastic bags.
