Transdev renews contract with Argent Energy to power buses with low-carbon fuel

Transdev, the north of England bus operator, has renewed its contract with renewable fuel supplier Argent Energy to continue using low carbon fuel, Dieselite® across its nine operating centres in Yorkshire, Lancashire and Greater Manchester.
Argent Energy has supported Transdev since 2023, when the operator transitioned its entire diesel fleet to low-carbon fuel as part of its broader decarbonisation strategy.
Under the renewed agreement, Argent Energy will continue supplying Dieselite and managing daily fuel operations across Transdev’s network, ensuring reliable refuelling, efficient depot logistics, and timely deliveries.
Transdev has moved beyond the UK standard B7 diesel (up to 7% biodiesel) to adopt Dieselite B10–B30, containing 10–30% sustainable, second-generation biodiesel. This transition has replaced up to 30% of fossil diesel across its 500-bus fleet.
Henri Rohard, managing director at Transdev said: “Argent Energy has supplied Transdev with Dieselite since 2023, and we are pleased to have renewed our contract now in 2026. This revolutionary partnership has enabled us to achieve incredible environmental benefits on a commercially viable basis, delivering on our commitment to low-carbon-emission bus transportation across the North of England. Transdev look forward to continuing to work with Argent Energy.”
Mike Copson, Group Head of Fuel Sales at Argent Energy said: “Transdev are doing a great job of decarbonising and it’s a privilege to support them by supplying them with our Dieselite fuel. Transdev need a fuel partner who are dependable, professional and keep their buses running reliably.
“Argent is proud to continue doing that with our sustainable and renewable alternative to straight diesel that saves carbon emissions and delivers a more sustainable public transport across the region.”
