URBACT is a European Territorial Cooperation programme designed to assist cities in developing sustainable urban strategies. It fosters collaboration among cities to share best practices and address shared urban challenges, with funding from the European Union. The programme encompasses all EU member states, as well as Norway and Switzerland. The initiative emphasizes integrated sustainable development, improving city policies, and enhancing Cohesion policy effectiveness in urban areas. It supports transnational networks that create and implement Action Plans to tackle common urban development issues while promoting the reuse of established good practices. Currently, URBACT IV, adopted in 2022, aims to help cities navigate green, just, and digital transitions. It offers networking and capacity-building activities while also preparing cities from five IPA countries for potential EU accession. The first call for participation in URBACT IV opened in January 2023, inviting cities to engage in Action Planning Networks.
