Join us at the Zero Emission Bus Conference @Busworld Europe in Brussels from October 7th to 9th, 2025.

Building on our previous successful editions, we will bring together transport operators & authorities, policymakers, manufacturers, and industry experts to discuss decarbonizing public and private transportation. Ticket sales will be released in due course.

ZEB 2025 is being organised by ERM in partnership with Busworld Foundation. Thanks to this partnership, the 6th edition of the European ZEB Conference will be held at Busworld Europe in October 2025. This will bring considerable mutual benefits to both events: the conferences and the exhibition. All ZEB attendees will have free entrance to the Busworld Europe 2025 exhibition.

The ZEB 2025 programme is designed to give bus and coach operators, public transport authorities, and local policy makers a complete overview of the considerations for deploying zero emission fleets at scale. Building on the feedback from ZEB 2023, ZEB 2025 will offer more in-depth technical content than ever before.

ZEB 2025

ZEB 2025 will complement the plenary sessions with interactive breakout sessions. Those breakout sessions are expected to facilitate more technical discussions and address key questions about the opportunities and challenges associated with battery and fuel cell buses.

ZEB 2025 is expected to be the biggest edition yet!

We have listened to your feedback from previous editions and the next edition of ZEB will have even more interactive elements including more technical breakout sessions, more live Q&A, a ZEB tour of Busworld and the same great networking opportunities!
