Assembly
Sept. 22-25, 2026 | Climate Week NYC
From September 22-25, Swissnex hosts Assembly, the main Swiss stage at Climate Week NYC, the world’s largest climate festival with over 1,000 events running in parallel to the UN General Assembly. As world leaders gather in Midtown Manhattan, Swissnex assembles Swiss and global voices – from private sector innovators and researchers to artists and policymakers – in the East Village for four days of communal climate thinking and action. The theme Assembly speaks to Swiss deliberation and democracy – the idea that a diverse body of citizens and communities must gather together to define their future collectively. Assembly also evokes an ongoing process: the combining of pieces to create new structures, echoing the work of building our collective climate future.
