In Canada, global negotiations on a treaty to end plastic pollution has completed its final meeting

The world’s nations finished a round of negotiations early Tuesday on a treaty to end plastic pollution and made more progress than they have in three prior meetings.

Coming into Ottawa, many feared the effort would stall to craft the first legally binding treaty on plastics pollution, including in the oceans. The last meeting was marred by disagreements and there was much left to do.

But instead, there has been a "monumental change in the tone and in the energy," said Julie Dabrusin, a Canadian parliamentary secretary.
