What’s the fastest way to get people to stop using plastic cups, plates and cutlery? How about banning them? That’s what’s happening in France after the government passed a new law that will ensure that all plastic cups, plates, and cutlery must be made of biologically-sourced materials that can be composted. The law, which comes into effect in 2020, is part of the Energy Transition for Green Growth—an ambitious plan that aims to allow France to make a more effective contribution to tackling climate change.
