Transforming Zagreb’s Public Transport Fleet: A New Era of Sustainability and Modernity
In a groundbreaking move, Zagreb is set to revolutionize its urban transportation system through a substantial investment in electric vehicle technology, backed by the European Investment Bank (EIB). This initiative aims to replace aging vehicles with modern, eco-friendly alternatives, drastically reducing city emissions and urban congestion. As part of this ambitious plan, 20 innovative trams and approximately 100 electric buses will launch the city into the forefront of sustainable mobility across Europe.
European Investment Bank’s Vital Role in Zagreb’s Transit Modernization
The EIB has opened a 75 million euro loan application to finance the procurement of cutting-edge transportation infrastructure, with full approval expected by the end of 2026. This financing strategy aims to cover nearly 41% of the total project cost, which is estimated around 184 million euros, signaling a robust commitment to greener urban transport.
- Funding Breakdown: The €75 million loan will support the acquisition of 20 state-of-the-art electric trams and approximately 100 electric buses.
- Implementation Timeline: The project spans from 2025 to 2030, ensuring a phased and well-structured fleet upgrade.
The Project Details: A Closer Look at New Vehicle Deployments
The city’s focus centers on replacing old, combustion-engine vehicles with zero-emission electric alternatives, significantly lowering the city’s carbon footprint. The new fleet will include:
- 20 modern, low-floor electric trams, each up to 34 meters long for high-capacity urban transit.
- Approximately 100 electric buses ranging from 9 to 18 meters in length, equipped with advanced battery technology for extended range and lower maintenance costs.
These upgrades will enable Zagreb to handle increasing passenger demand more efficiently, reduce urban noise, and cut down air pollution—making the city more livable and environmentally friendly.
Why This Shift Toward Electric Vehicles Matters
Transitioning to electric transit is a key strategy in meeting climate targets and improving urban quality of life. Electric vehicles produce no tailpipe emissions, eliminate dependence on fossil fuels, and contribute to an improved environment. Zagreb’s initiative aligns with broader European Union goals to decarbonize transportation and promote clean energy adoption.
Moreover, electrification offers operational benefits such as decreased fuel costs, lower maintenance requirements, and the potential for integration with renewable energy sources—creating a sustainable, cost-effective transit ecosystem.
Past and Future Investments: Building on a Strong Foundation
Before seeking this new €75 million loan, Zagreb already made strides in renewal fleet. In late 2025, the city successfully incorporated 20 Končar-produced low-floor trams valued at nearly €50 million, with subsequent contracts securing 62 electric buses.
European funds, primarily from the European Union’s REACT and Resilience and Recovery Plans, financed these initial investments—highlighting the city’s ongoing commitment to leveraging multilateral support for urban development.
The Infrastructure and Supply Chain Strategy
Critical to launching this fleet upgrade will be establishing a reliable supply chain and supporting infrastructure. While the procurement details concerning vehicle manufacturers remain under review, the city plans to:
- Issue new tenders for vehicle deliveries in the upcoming months.
- Develop charging infrastructure that integrates seamlessly with existing power grids and supports rapid charging capabilities.
- Ensure integrated planning for fleet deployment, maintenance, and operational efficiency.
This comprehensive approach guarantees a smooth transition to electric transit and maximizes the environmental and economic benefits.
Anticipated Impact and Long-Term Benefits
This project not only underscores Zagreb’s dedication to sustainable urban mobility but also sets an example for peer cities worldwide. The immediate benefits include:
- Significant reductions in greenhouse gas emissions
- Improved air and noise quality
- Enhanced public transport services with increased capacity
- Long-term cost savings in operation and maintenance
Over the long term, the incorporation of electric vehicles will foster a healthier, more environmentally resilient city that encourages residents to choose public transit over private cars, further diminishing traffic congestion and pollution.
