More than 85 nations, including all 27 members of the European Union, are making a last-minute push to include caps on plastics production in any deal.

Negotiators aiming for an international treaty to curb plastic pollution are set for fierce debate on the last day of scheduled talks, as over 100 countries supportive of a pact that would cap plastic production face off against a handful of oil-producing countries who want it focused just on waste.

The world’s nations will wrap up negotiating a treaty this weekend to address the global plastic pollution crisis. Their meeting is scheduled to conclude Sunday or early Monday in Busan, South Korea,

One point of agreement between plastics industry groups and environmental organizations is that neither side likes a U.S. proposal put forward at the global treaty talks related to chemicals and "problematic" plastics.
