NetZeroCities (EU Cities Mission Platform)

NetZeroCities is a significant initiative funded under the European Union's Horizon 2020 Research and Innovation Programme, aimed at supporting the EU Mission "100 Climate-Neutral and Smart Cities by 2030." Managed by a consortium of 33 partners from 27 European countries, and led by EIT Climate-KIC, this project serves as the official Mission Platform for the EU Cities Mission, helping 112 selected cities achieve climate neutrality by 2030.

The platform acts as a service-oriented hub that provides customized technical assistance, finance and investment advisory services, and opportunities for peer-to-peer learning. Its primary objective is to help cities navigate structural, institutional, and cultural barriers that hinder their progress toward climate neutrality. The cities that meet this goal are expected to become centers for experimentation and innovation, paving the way for all European cities to follow by 2050.

A crucial feature of the NetZeroCities methodology is the development of Climate City Contracts (CCCs). These strategic frameworks are collaboratively created by city administrations, local stakeholders, and national governments. Each CCC aligns a city's decarbonization commitments with a comprehensive investment plan and governance model, ensuring that climate targets are supported by actionable financing and institutional arrangements. This approach emphasizes that achieving net-zero emissions necessitates systemic change, integrating infrastructure investment with social innovation, regulatory reforms, and citizen engagement.

NetZeroCities features several dedicated programmes, including the Pilot Cities Programme, which funds and supports ambitious demonstration projects in selected cities, testing innovative urban decarbonization strategies. The Twin Cities Programme pairs Mission Cities with other European cities to share knowledge and replicate successful initiatives. Additionally, the NetZeroCities Portal offers access to tools, resources, datasets, and knowledge on decarbonization topics, fostering collaboration through online communities and learning groups.

The initiative addresses several key thematic areas such as energy-efficient building renovation, renewable energy deployment at the district scale, sustainable urban mobility, circular economy practices, and nature-based solutions. NetZeroCities emphasizes the importance of ensuring that the transition to climate neutrality is socially inclusive, tackling issues like energy poverty and equitable access to green infrastructure.

In terms of housing and the built environment, NetZeroCities assists cities in accelerating deep energy renovations of existing buildings and deploying renewable energy systems at the neighborhood and district level. The platform's policy initiatives stress the need for multi-level governance, coordinating EU, national, regional, and local policy frameworks to mobilize diverse public and private capital flows for financing large-scale sustainable housing and urban infrastructure programmes.

Since its expansion in 2024, the Mission Platform has extended specific support services beyond the original 112 Mission Cities, offering peer-learning opportunities and access to online resources to all cities across Europe and Horizon-associated countries. The initiative is overseen by the European Climate, Infrastructure and Environment Executive Agency (CINEA) on behalf of the European Commission.
