This Earth Day (22 April), European Athletics celebrates the success of the European Running Championships held in Brussels-Leuven on 12–13 April—and the bold example it set in sustainability and environmental responsibility.
With over 28,000 participants and more than 300 elite athletes across the marathon, half marathon, and 10 km, the championships were designed to be a benchmark for sustainable sports events.
In collaboration with the Flemish government, local authorities, and the organising committee (LOC), a comprehensive sustainability strategy was implemented, covering energy use, water management, mobility, waste reduction, and more.
Smarter Energy Use
A core ambition was to minimise energy consumption. The event offices were eco-friendly, incorporating green roofs, solar panels, and energy-efficient designs. Temporary diesel generators were limited by connecting to local green urban power grids in Brussels and Leuven wherever possible.
Where that wasn’t feasible, battery packs and biodiesel generators were used according to a strict priority order.
Water-Saving Measures
Water use was reduced by promoting reusable water bottles and installing drinking fountains for participants, spectators, and staff. Efforts were also made to limit water transportation and packaging.
Public toilets were used wherever possible, supplemented by eco-friendly mobile units only when needed. At several supply points, drinking water was provided directly from the public water network.
Waste Not, Want Not
Avoiding and managing waste was a major priority. A detailed waste management plan, designed with external partner Ecofest, guided operations. Participants were encouraged to bring their own cups for water at supply zones, and eco-teams on cargo bikes assisted with waste collection.
A plogging (picking up litter and jogging) event the day after the races helped further clean up the course.
To reduce waste even further, the event embraced digital tools—with fewer flyers, less printed material, and more QR codes. Clothing left behind at the start was collected and donated for reuse.
Finishers T-shirts from Recycled Bottles
The t-shirts provided to every finisher was made from sustainable sources by Scitimar Sportswear. Approximately six plastic bottles go into the making of each t-shirt, which are also recyclable.
Healthy, Sustainable Catering
Food and drink offerings focused on healthy, plant-based options with reusable systems. Reusable cups were standard in fan zones, and glass or porcelain was used in VIP and media areas. Food waste was minimised through careful planning and real-time attendance tracking.
Greener Mobility
Transport was a key concern. Working with Scelta Mobility, the event encouraged fans and participants to follow the STOP principle: walking, cycling, public transport, and lastly private cars.
Electric vehicles supported the races, and international athletes received travel guides promoting trains and coaches over flying. Incentives were also offered for those who cycled to the venue.
Inclusivity and Safety
The championships were committed to being inclusive and accessible. Special seating and parking were available for people with disabilities, and disadvantaged groups had access to discounted participation.
In terms of safety, a dedicated team from ToB-Seen and the Red Cross provided on-site security and medical support. Fair play was prioritised, with anti-doping measures and respect for athletes, fans, and the environment encouraged throughout.
Leaving a Lasting Legacy
Sustainability didn’t end when the last runner crossed the finish line. The event set plans in motion for an annual marathon in Leuven and promoted the continued use of tap water at supply stations in future races. A full sustainability audit is now underway to identify areas for further improvement.
With its far-reaching commitment to environmental and social responsibility, the 2025 European Running Championships set the pace in building a greener, more inclusive sporting future.
