Negotiators at United Nations–led talks in Nairobi, Kenya have failed to agree on how to advance toward the development of a global treaty to end plastic pollution. Environmental advocates say some oil-producing governments used stalling tactics designed to ultimately weaken the treaty. Delegates were expected to discuss a draft published in September that represented the views from the first two meetings. The Intergovernmental Negotiating Committee for Plastics is mandated with creating the first international, legally binding treaty on plastic pollution in five rounds of negotiations.
