Fujitsu Launches Proof of Concept with Polish City to Accelerate Fleet Decarbonization Through Digital Rehearsal Technology

Munich, November 06, 2025

Fujitsu is working with the city of Rybnik in Poland, to increase the efficiency of zero-emission bus operations to further reduce GHG emission while maintaining service levels and economic viability. It is pioneering the use of digital rehearsal technology to address one of the most pressing challenges facing fleet operators worldwide. This new project demonstrates how Fujitsu's data-driven approach enables cities and logistics operators to optimize multi-fuel fleet operations and strategies, by reducing uncertainty and risk in decarbonization planning.

The urgent imperative to decarbonize is a challenge facing fleet operators worldwide, due to operational realities such as limited infrastructure for zero-emission vehicles, significant capital investment requirements, and the need to maintain a reliable service. This complexity often leads to missed decarbonization targets, hidden inefficiencies, and prolonged dependency on high-emission fuels. Fujitsu's fuel optimization framework, developed under its Social Digital Twin (SDT) technology, addresses this challenge by enabling digital rehearsal of decarbonization strategies before real-world implementation.

The Rybnik project evaluates the city's 36 multi-fuel bus fleet, determining the optimal combination of hydrogen, and hybrid internal combustion engine vehicles to minimize emissions while maintaining essential service levels, supporting operational planning. Unlike traditional simulation tools that rely on averaged data, Fujitsu's approach captures granular, route-specific information such as how individual bus routes impact fuel consumption across different terrains and operating conditions. This route-level precision enables fleet operators to make data-driven decisions about where to deploy limited hydrogen bus routes, creating an economically viable pathway in operation. The project results also identify further possibilities for reducing GHG emissions and the necessary strategic changes required to achieve this goal, such as more flexible driver shift planning.

Fujitsu's Digital Rehearsal capability empowers public transport, logistics and fleet operators to test multiple scenarios before committing capital, answering critical questions about where green infrastructure should be deployed, and determining routes best suited for zero-emission vehicles. It also takes into account how a mixed fleet can optimize environmental impact without compromising service reliability. By uncovering previously unrealized opportunities for efficiency across the entire logistics chain, the framework supports organizations with setting realistic decarbonization strategies and, reducing costs while accelerating net-positive outcomes.

The technology is mode-agnostic and fuel-agnostic, designed to foster breakthroughs in complex operational environments where infrastructure is still evolving. Fujitsu reinforces its commitment to solving real-world societal problems through technology that builds trust and enables a sustainable future.

Fujitsu's Net Positive research initiative focuses on delivering sustainability outcomes alongside with economic viability, ensuring that the transition to clean transportation doesn't require a leap of faith but is grounded in precise real-world data and sophisticated simulation.
