25 Nov 2022 --- Next week, the United Nations intergovernmental negotiating committee will meet in Punta del Este, Uruguay, to develop an international legally binding treaty on plastic pollution. However, scientists have voiced concerns about the treaty’s success, flagging that the negotiations could overlook the diversity and complexity of chemicals in plastics, which would “severely undermine” the treaty’s effectiveness. The upcoming negotiation is only the first in a series of Intergovernmental Negotiating Committee (INCs) meetings expected to last until the end of 2024. However, the INC next week marks an important start to the discussions that aim at achieving an ambitious global plastics treaty needed to tackle the plastic and climate crisis.
