As Earth Day 2024 puts a spotlight on the world's climate crisis, negotiators from 175 countries are gathering for the fourth round of the United Nations Plastics Treaty negotiations next week in Canada. Held in Ottowa, Canada, from April 23-29, the last major round of negotiations will bring together the treaty's Intergovernmental Negotiating Committee (INC) to draft a global, legally binding agreement by the end of 2024, according to the U.N. "Global plastic production and consumption has grown exponentially since the 1950s and is set to increase by 70% by 2040 if business continues as usual," the INC reported in a press release ahead of the negotiations.
