Achieving climate neutrality across Europe depends on effective collaboration between cities, national governments, and European institutions. National platforms are emerging as key enablers of this collaboration, aligning local ambition with European policy and turning climate goals into coordinated, actionable strategies. National Mission Ecosystems and dedicated platforms serve as a “shared software” for collective action, providing spaces for trust-building and the co-creation of scalable solutions involving at the national scale, the private sector and civil society organisations.
National platforms institutionalise cooperation and provide cities with a clear pathway to accelerate their climate transition while contributing to a cohesive, Union-wide transformation. More than coordination mechanisms, they create dedicated spaces for dialogue (a community), support, multi-city work and problem-solving, as well as bridging the gap between local innovation and national decision-making. In doing so, National Platforms and National Mission Ecosystems help connect bottom-up urban action with the authorities that can shape regulation, unlock funding, and remove systemic barriers.
On this page, you will find examples of how national platforms are established across different countries, along with the instruments and methods they use to engage with and support cities in their journey toward climate neutrality, as well as examples of collaboration with national and regional authorities.
