The World Summit of Local and Regional Leaders, convened by United Cities and Local Governments (UCLG), is the largest gathering of mayors, presidents of associations, councillors, and local and regional practitioners from around the world. It is also the World Summit of the most influential local and regional leaders, councillors, local governments, partners, and actors implicated in the decision making of city and community life. This year’s edition will count on a renewed format and enhanced collaboration between members and partners. Building on the century-old international movement of municipalities, the World Summit of Local and Regional Leaders will include interactive and innovative formats built on four tracks that will guide participants through their World Summit experience, together with dedicated sessions for UCLG membership. The triennial UCLG Congress also builds on the legacy of the commitments of the local and regional governments constituency around the world. A commitment to ensure a better future for all through action at local, national and international levels. A commitment to govern and build in partnership, a commitment for cities and regions to take their rightful place at the head of a new international agenda for inclusive and sustainable development.
