Cardiff Bay (Cardiff Daily) June 27, 2026 – The winners of a Wales-wide school climate challenge have been announced in Cardiff after pupils from across the country presented creative ideas aimed at tackling waste, pollution, climate change, biodiversity loss and ocean health.

What was announced at the Cardiff ceremony?

As reported by Nation.Cymru staff of Nation.Cymru, the winners of Keep Wales Tidy’s school innovation challenge were unveiled at a celebration event at Techniquest in Cardiff Bay. The competition formed part of Climate Challenge Cymru and invited primary and secondary schools across Wales to submit short videos showing practical responses to major environmental problems.

The five challenge themes were Build a Waste-Free World, Clean Our Air, Fix Our Climate, Protect and Restore Nature and Revive Our Oceans.

The event brought together pupils, organisers and invited guests for the awards presentation. According to the report, BBC presenter Will Millard, nature campaigner Joe Wilkins and Mrs Morfudd Meredith, Lord-Lieutenant of South Glamorgan, attended the ceremony.

Which schools were named winners?

According to Nation.Cymru staff, Ysgol Gymraeg Ffwrnes in Carmarthenshire was the standout winner, collecting two awards on the day.

The school won in the Revive Our Oceans category and the Fix Our Climate category. Judges praised its work on seagrass habitats and eco-moorings, and also its exploration of local food as a way to reduce carbon emissions.

Griffithstown Primary School in Torfaen won the Clean Our Air Award. The report said its film focused on nature-based design and renewable energy, including solar-powered green roof gardens designed to improve air quality.

Ysgol Bryn Coch in Flintshire won the Build a Waste-Free World category after research into waste reduction and reuse, including composting, food redistribution and pre-loved uniforms.

Ysgol Penrhyn Dewi in Pembrokeshire took the Protect and Restore Nature prize. The school was recognised for creative solutions to biodiversity loss and water pollution, including solar-powered river and lake protection. The report also said the winning videos can be found on the Keep Wales Tidy website.

Why does this challenge matter?

Climate Challenge Cymru is designed to involve young people in environmental problem-solving through practical school projects. The initiative is inspired by The Earthshot Prize, which is used as a framework for the five “Earthshots” in the competition.

By asking pupils to think in terms of waste, air quality, climate, nature and oceans, the challenge links classroom creativity with real-world environmental issues.

The Cardiff ceremony turned those ideas into public recognition for schools that produced the strongest submissions.

The awards also show how local projects can be presented as examples of wider action on environmental sustainability.

How were the winners presented?

The report attributes the ceremony to Keep Wales Tidy’s Climate Challenge Cymru celebration at Techniquest in Cardiff Bay. It notes that the event gathered winners and special guests in one place to recognise the schools’ work.

The schools were not just judged on broad themes but on specific ideas, as shown in the details provided about seagrass habitats, renewable energy, composting and biodiversity protection.

That emphasis on practical action appears to have been central to the awards. Each winning project was tied to a different environmental problem, with the judges recognising both creativity and relevance.

What is the background to this development?

Keep Wales Tidy’s Climate Challenge Cymru is a nationwide school innovation challenge inspired by The Earthshot Prize.

The organisation invited learners to submit short videos with their own ideas for tackling major global environmental issues.

The challenge was built around five categories, allowing schools to choose the topic that best matched their project or area of interest.

The winning ceremony in Cardiff Bay followed that process and served as the public announcement of the schools selected by judges. The format suggests the initiative is intended not only to reward schools, but also to share ideas across Wales through the published videos.

What is the prediction for schools and communities?

For pupils and schools, the announcement is likely to encourage more participation in future environmental projects because it shows that practical school-based ideas can be recognised at national level. For local communities, the projects highlighted in Cardiff may help raise awareness about issues such as waste reduction, clean air, climate action and nature restoration.

The challenge may also motivate other schools to adopt similar approaches, particularly where ideas can be applied through everyday changes in classrooms, school grounds and local partnerships.
