In Geneva, efforts to secure an international treaty to curb plastic pollution are in doubt on the final day of negotiations. Nearly 100 of the 184 countries gathered at the United Nations talks rejected the latest draft agreement as “unambitious” and “inadequate.” The proposed text puts no limits on plastic production and makes no mention of the chemicals used in plastic products. The plastics industry has been lobbying heavily in opposition to production limits, as have several powerful oil and gas-producing nations, including Saudi Arabia and the United States.
