Ahead of the fourth session of the Intergovernmental Negotiating Committee (INC-4) for a global plastics treaty, scheduled in Ottawa, Canada, from April 23 to 29, the Quaker United Nations Office (QUNO), in collaboration with a coalition of civil society organizations and international entities, drafted a letter urging the Swiss government to adopt an ambitious stance in the negotiations. This initiative, part of the United Nations Environment Programme (UNEP), aims to develop an international legally binding instrument on plastic pollution (ILBI).
