The CE4CE Knowledge Platform, developed within the Interreg CE4CE project, is a comprehensive digital hub designed to support the transition towards circular economy practices in public transport. It brings together knowledge, tools, and practical resources to help public transport authorities, operators, and other stakeholders understand, assess, and implement circular solutions across their organisations and networks.
The platform is structured around four key components. The Circularity Compass provides a self-assessment tool that allows organisations to evaluate their current level of circularity across different areas of public transport systems and identify opportunities for improvement. The Best Practices section showcases real-life examples and pilot actions from across Europe, demonstrating how circular economy principles can be applied in practice in areas such as infrastructure, vehicles, and energy systems.
The Knowledge Hub serves as a central repository for structured information, methodologies, and project outputs, supporting learning and knowledge transfer among stakeholders. It helps translate circular economy concepts into practical guidance that can be used in planning, procurement, and operational decision-making.
In addition, the Matchmaking Forum facilitates collaboration between public transport operators, authorities, suppliers, and other life-cycle actors. It enables the exchange of offers and requests for vehicles, components, and spare parts, supporting reuse and extending the lifetime of existing assets within public transport systems.
Together, these four components create an integrated ecosystem that supports awareness-raising, capacity building, and practical implementation of circular economy principles. The platform encourages cooperation across sectors and countries, helping to accelerate the transition towards more resource-efficient, sustainable, and circular public transport systems.

The CE4CE Knowledge Platform will be maintained by trolley:motion after the project ends, ensuring the long-term availability, update, and scalability of the platform for public transport stakeholders across Europe.
