We are being forced to use more plastic than we need and in a way that makes it impossible to responsibly manage. To this point, plastic producers have operated with little accountability and regulation. The absence ( 7 ) the price. And we are now facing an accelerating threat that crosses borders and puts everyone in harm's way. To end the plastic crisis, the UN plastic pollution treaty must introduce new global binding rules to regulate production and consumption. These rules must include measures to ban, phase-out, phase-down, circulate and manage high-risk plastic products. As a priority, we need a treaty to ban the most harmful and avoidable plastic products. Over 90% of the plastic ( 1 ), such as plastic cutlery, and microplastics, such as those added to cosmetic products. Most of which is too difficult or dangerous to recycle. So, while plastic production continues to skyrocket, ( B ). To end plastic pollution, we need to ban the highest polluting, most harmful and avoidable plastic products and materials, and support all nations as they shift to safe, circular systems.
