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 emissions 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 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!

Previous editions

The 5th edition of the Zero Emission Bus Conference was held in Brussels on 9th-12th October 2023. Over 430 attendees heard from >70 speakers and >90 representatives from transport operators and authorities attended.

The 2023 Zero Emission Bus Conference was the biggest-ever edition, and the first to be held at Busworld Europe, the world’s largest B2B bus and coach exhibition.

The 4th edition of the European Zero Emission Bus conference was held in Paris on 17th & 18th November 2021. The conference was held over two days at the Maison de la Chimie and attended by 400 attendees from the zero-emission bus sector. Experienced operators and industry experts outlined the pathways towards achieving full fleet transitions to zero emission.

What we accomplished:

  • A successful in person event during COVID-19, meeting COVID guidelines and regulations.
  • A digital QR code programme – No programmes were printed at this event, making it more environmentally friendly.
  • A conference with approximately 50 speakers in person and some virtual due to regulations in their country.
  • We ran shuttle bus tours with our sponsors Caetano and IVECO’s buses, one hydrogen and one battery electric.
  • 17 sponsors participated with exhibition booths; we received positive feedback from everyone looking forward to the next ZEB.

Throughout the autumn of 2020, the organisers hosted a series of free webinars in the lead up to the 4th conference edition in Paris 2021.

The ZEBINAR programme covered key elements of the transition to zero emission. Participants heard directly from operators on how they are integrating zero emission vehicles into their bus fleets; industry representatives developing zero emission infrastructure and vehicles; and policy makers developing the next phase of European directives.

The programme covered the following topics:

Zero Emission Buses & The Green Recovery – Tuesday 22nd September 2020
An overview of the policy framework and strategies for accelerating zero emission bus deployment in Europe. Speakers discussed how zero emission buses can play a part in Europe’s green recovery strategy.

Transforming Infrastructure: HYDROGEN – Tuesday 13th October 2020
Industry representatives discussed solutions for rolling out affordable infrastructure and pathways to green hydrogen.

Transforming Infrastructure: BATTERY – Tuesday 10th November 2020
Industry representatives and bus operators discussed solutions for rolling out affordable and reliable recharging infrastructure. Speakers tackled topics including connection to the grid, interoperability, and smart charging solutions.

Optimising Operations: Considerations For A Full Fleet Conversion – Tuesday 1st December 2020
Operators shared their experiences and best practices of operating ZE buses. Speakers shared their practical solutions for integrating zero emission buses into their existing fleets and plans for transitioning to fully zero emission fleets in the 2020s.

The 2nd edition of the European Zero Emission Bus conference was held in Cologne on the 27th & 28th November 2018. 

With over 350 attendees, the European Zero Emission Bus (ZEB) conference 2018 successfully brought together an audience of policy makers, bus manufacturers, operators, local authorities and industry experts.

The 1st edition of the Zero Emission Bus conference was held in London on 30th November 2016. Over 250 high level stakeholders from 22 countries attended the event, including representatives from local authorities, transit operators, industry, and national and financial regulatory and funding agencies held lively discussions around zero emission bus (ZEB) technologies’ readiness levels and commercialisation paths.

It was agreed unanimously that ZEB technologies are ready to be deployed globally.

Below the expected key topics to be tackled during ZEB 2025

Grid challenges - capacity
and procurement
Depot energy
BEB & FCB performance
and drivetrain development
Business models to meet
increasingly CAPEX-
intensive operations
Maintaining ZEB fleets

Venue & hotel

The European ZEB 2025 conference @Busworld Europe was held at the Brussels Expo Centre, located in the north of the capital city of Belgium.

Busworld Europe hosts over 500 exhibitors, including the 80 most important bus builders in the world, suppliers of charging and fuelling infrastructure, energy management systems, providers of engines and powertrains, Intelligent Transport System (ITS), Advanced Driver Assistance (ADAS), etc.

Busworld attracts 35 000 visitors coming from 143 countries.

The distinctiveness of the Brussel Expo Centre lies in the originality of its architecture, which dates to the early 1930s with architectural style of Art Deco. This functional venue offers a variety of settings for conferences, and naturally creates an environment beneficial to the exchange of ideas, while bringing together all the material and equipment necessary to ensure the success of an event such as the European Zero Emission Bus Conference.
