This statement argues that to truly ensure that no one and no place is left behind and that we achieve the SDGs, a more networked multilateral system based on multilevel governance, and multi-stakeholder collaboration is needed. This renewed multilateral system needs to consider the many dimensions of an urban world: a system of rural and urban territories, small and intermediary cities, metropolitan entities and regions; and needs to deliver financial support and capacity development for local and regional governments (LRGs) to participate in this transformation. A whole of government and whole of society approach is also essential to address inequalities, climate change, and to foster peace to transform our systems.
