Polish bus manufacturer Solaris has obtained Environmental Product Declarations (EPDs) for three electric bus models as the company expands environmental transparency across its zero-emission vehicle portfolio.
The newly certified models include the Solaris Urbino 10.5 Electric, Solaris Urbino 12 Electric and Solaris Urbino 18 Electric.
Solaris said the independently verified EPD datasets cover the full life cycle of the vehicles, including raw material extraction, component production, manufacturing, transport, operation, servicing and end-of-life processing.
Environmental Product Declarations are internationally recognised environmental labels designed to provide standardised information about a product’s environmental impact.
According to Solaris, the EPDs were developed in accordance with ISO 14025 standards and Product Category Rules requirements applicable to city and intercity buses.
The declarations are based on Life Cycle Assessment (LCA) analysis, which evaluates factors including emissions, energy consumption, recycling potential and the influence of regional energy mixes on vehicle environmental performance during operation.
Solaris said the assessments are intended to help identify opportunities for environmental optimisation across supply chains, manufacturing operations and vehicle energy efficiency.
The company added that the new EPD certifications confirmed recyclability levels ranging from approximately 96% to nearly 98% depending on the vehicle model.
According to Solaris, the results support the buses’ compatibility with circular economy principles and demonstrate reduced environmental impact across the full vehicle lifecycle.
The manufacturer said Environmental Product Declarations are increasingly being used by public transport operators as part of procurement evaluations alongside technical performance and operating costs.
Solaris had previously obtained EPD certifications for the Solaris Urbino 18 Hydrogen, the Solaris Urbino 18 Electric and the Solaris Urbino 12 Hybrid.
The company said expanding the number of vehicles carrying EPD certifications forms part of its broader sustainability and environmental impact reduction strategy.
