Thank you for participating!


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.

Operators, policy makers, manufacturers, and industry from around the world met in Brussels to discuss the status and plans for transitioning the European bus and coach sectors to zero emission. The 5th edition of the conference was organised by ERM (previously Element Energy) in partnership with Busworld Foundation.

Previous editions

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.
