On the sidelines of the 79th World Health Assembly (WHA79), the Health Diplomacy Alliance and Geneva Environment Network hosted the Health Diplomacy House on Thursday, 21 May 2026. The House was an informal working space where organizations can convene sessions, hold discussions, and collaborate on practical health policy issues. Part of the “Predictable Uncertainty” series, it brings together policymakers, diplomats, academia, civil society, philanthropic organizations, and patient groups.

The programme consisted of roundtables, small group discussions, and space for bilateral meetings and media engagement, with a flexible agenda expected to cover topics such as One Health, antimicrobial resistance, climate and health, health financing, and global health governance.

This growing recognition was reflected at the Seventy-sixth World Health Assembly (WHA76), held in Geneva in May 2023, where Member States adopted a resolution on the impacts of chemicals, waste, and pollution on human health. Initially tabled by Peru, Canada, Colombia, Ecuador, El Salvador, Mexico, Monaco, Switzerland, Uruguay, and the European Union and its Member States, the resolution calls for scaling up work on plastics and health. It also encourages contributions to the Intergovernmental Negotiating Committee (INC) mandated UNEA Resolution 5/14 to develop a legally binding instrument on plastic pollution, including in the marine environment. The resolution further acknowledges related multilateral processes, including those under the Human Rights Council.

Since then, WHO has called for the highest attainable standard of human and environmental health to be a core objective of the plastics treaty. WHO has highlighted the need to address both known and anticipated health risks associated with plastics, including chemicals and additives, as well as microplastics and nanoplastics, across all stages of the plastics lifecycle.

This event featured Lightning Talks by diplomats, scientists, policymakers, and other experts. These talks will highlight why it is essential to communicate more clearly, consistently, and effectively about the health impacts of plastic pollution, and why health must be placed at the centre of global action on plastics.
