Updated PCR for Public and Private Passenger Buses and Coaches Supports Harmonised Environmental Assessments in Procurement
The newly published version 3.0.0 of PCR 2016:04 supports more informed and environmentally responsible procurement decisions for buses and coaches by strengthening the methodological foundation for Environmental Product Declarations (EPDs).
On 28 September 2026, the International EPD System published version 3.0.0 of Product Category Rules (PCR) 2016:04 for public and private passenger buses and coaches, marking an important step towards more robust and harmonised environmental assessments in the transport sector.
The revision was developed through a collaborative process involving leading vehicle manufacturers, including Volvo Buses and Scania, alongside other industry stakeholders, reflecting a shared commitment to advancing environmental transparency.
A key improvement is the incorporation of selected methodological elements from TranSensus LCA, a Horizon Europe research initiative focused on developing a harmonised Life Cycle Assessment (LCA) approach for zero-emission road transport. These elements contribute to strengthening the LCA methodology within the framework of the International EPD System.
“The growing interest in EPDs in the sector makes a robust and consistent PCR increasingly important. The update provided a valuable opportunity to build on the knowledge and experience from the TranSensus LCA project, and it is encouraging to see elements of the methodology reflected in the updated PCR,” says Julia Lindholm at IVL Swedish Environmental Research Institute, which played a leading role in the TranSensus LCA consortium.
For public and private procurement, the updated PCR provides a stronger methodological foundation for assessing the environmental performance of buses and coaches. The methodological improvements aim to enhance the robustness and consistency of LCA calculations, supporting more reliable environmental information for evidence-based purchasing decisions and the integration of life cycle environmental considerations into tender requirements and supplier evaluations. With 97 registered EPDs under this PCR in the International EPD System, led by China (43.9%), Sweden (13.1%) and Germany (10.3%), the update is particularly relevant to a growing body of environmental product information in the sector.
The update reinforces the International EPD System's commitment to supporting manufacturers, procurement professionals and other stakeholders in advancing the transition towards more sustainable passenger transport.
