What we do

About LDT4SSC:
Better city and community services with local digital twins
Across Europe, cities and communities face similar challenges: how to use energy more efficiently, reduce pollution, improve public services and adapt to climate change. LDT4SSC, short for Local Digital Twins for Smart Sustainable Cities, brings cities together to share digital tools that help tackle these problems. These tools, called Local Digital Twins, are like digital copies of real places. They use data and Artificial Intelligence (AI) to help local governments make better decisions. For example, by predicting traffic, improving waste collection or planning green spaces. We connect existing digital platforms across Europe and support local teams to develop real-life pilot projects using open technology. These pilots show how digital twins can work in the real world and help cities learn from each other. Together with partners from governments, research and tech, we’re building a strong European network where cities — big and small — can access the tools, knowledge and support they need for a smarter, more sustainable future. This project is funded by the Digital Europe Programme and supports the EU’s goal of a digital, green and inclusive society.

What we focus on

Smart AI solutions
We support cities and communities in creating practical AI tools that solve real community problems, from predicting energy use to improving public transport.
Connecting digital tools across Europe
We help local digital twins work together by using common standards and shared data. This makes it easier for cities to learn from each other and scale up what works.
Fair and sustainable innovation
We promote open, ethical technology that supports local economies, protects citizens’ rights, and aligns with Europe’s digital and green goals.

What we do and why it matters

1. Linking existing digital twins across Europe We’re connecting the digital tools cities and communities already use - like traffic monitors, energy trackers or environmental sensors - into one shared European network. This makes it easier to collaborate, reuse tools and help smaller communities get on board.
2. Testing smart solutions in the real world Through hands-on pilot projects, we support cities to build practical services using AI and local digital twins. These pilots aim to improve daily life, from better planning and faster services to smarter decision-making.
3. Expanding Europe’s toolbox with AI innovation We’re adding new AI-powered tools to the existing EU Local Digital Twin Toolbox -like simulation models, prediction tools and self-organising systems -to help cities tackle challenges more quickly and flexibly.

Why it matters for Europe’s digital future

Europe’s digital growth is being held back by high costs, complex rules and scattered expertise. LDT4SSC helps overcome these barriers by:

• Bringing cities together to share needs and solutions
• Encouraging ethical, people-centred AI
• Supporting open technology and fair digital markets
• Working with the European Digital Infrastructure Consortium (EDIC) to create strong, connected systems across borders

We’re proud to support the Digital Europe Programme in building a more inclusive, innovative and sustainable digital society.

Who works with us

LDT4SSC brings together a diverse and experienced group of partners from across Europe. The consortium includes public research institutes, universities, non-profits, local authorities and open-source technology providers, all working together to advance interoperable Local Digital Twins and AI-driven services across Europe. This collaboration is made possible with the support of the European Union as the funding authority, ensuring alignment with broader EU digital and innovation priorities.

The project officially started in June 2025 and will run until December 2028. The first open call for pilot projects is scheduled to launch in month 5, inviting multi-stakeholder consortia to propose impactful, real-world use cases that advance the development and deployment of Local Digital Twins across Europe.
