The 2025 IAME Waterswift Restricted Cadet Class, one of four classes within the British Kart Championships, has been powered by sustainable fuel thanks to funding provided by the Mercedes-AMG PETRONAS F1 Team. Delivered in collaboration with Motorsport UK, the use of sustainable fuel from Round Three of the Championship achieved a 55% reduction in emissions compared to its fossil fuel equivalent.

The British Kart Championships has served as the training ground for many of our drivers as they honed their skills and technique in junior motorsport. George Russell, along with rising stars from the Junior Programme, including Kenzo Craigie and Ethan Jeff-Hall, all carved a path through the series.

"Karting plays a vital role in shaping the future of our sport, offering young drivers a strong foundation as they rise through the ranks. It's great to see the work that our team is doing with sustainable fuels in Formula One, and I'm pleased that this ambition is being extended at grassroots level to the British Kart Championships."

Funding the use of sustainable fuel in the IAME Waterswift Restricted Cadet Class during the 2025 season upholds our legacy of supporting up-and-coming racing talent and demonstrates our commitment to create a more sustainable future for motorsport.

As a team, we are committed to engineering change on and off the track, and our sustainable fuels strategy has been developed to help us reach our goal of Net Zero by 2030, whilst also catalysing wider adoption beyond Formula One.

"We are proud to have worked closely with the Mercedes-AMG PETRONAS F1 Team on this important step towards more sustainable motorsport. While fuel use in the British Kart Championships is a small part of motorsport's carbon footprint, it is perhaps one of the most visible. Switching to sustainable fuel provides the opportunity for young drivers to develop their skills whilst also helping to reduce the carbon emissions of our sport, without compromising on performance. We are committed to adopting sustainable fuel in UK motorsport."

Bradley Lord, Team Representative, Mercedes-AMG PETRONAS F1 Team

"Our team is dedicated to the pursuit of sustainable high performance, and this begins at grassroots level. Karting lays the foundation for most Formula One drivers and, just as we are preparing for our sport to enter a new era in 2026, we are proud to be catalysing change across the wider motorsport ecosystem. We would like to extend our thanks to Motorsport UK for collaborating with us on this project, which has seen us help the next generation of racers drive towards a more sustainable future."
