Blue Peter Earthshot competition winners meet The Prince of Wales at Windsor Castle
Published
The Prince of Wales has hosted the five winning children at a special reception at Windsor Castle.

Blue Peter has announced the winners of the Blue Peter Earthshot Competition, which invited children aged 5 – 15 to come up with an idea to help save the planet and be recognised by His Royal Highness The Prince of Wales’ Earthshot Prize.

The five winners met The Prince of Wales at Windsor Castle and had the opportunity to ask His Royal Highness questions about the environment. They also joined The Prince for a Blue Peter ‘Here’s One I Made Earlier’ moment creating Earthshot themed eco-friendly bird feeders together.
At the special reception inside Windsor Castle, each of the winners presented their winning idea to The Prince, who then awarded them with their certificates.
The Earthshot Prize is a global environmental prize and platform, founded by The Prince in 2020, designed to discover, accelerate and scale ground-breaking solutions to repair and regenerate the planet.
The five winners include:
- Marni, aged 8 from London, who came up with an idea for family forests where a tree is planted for every person in the UK.
- Mia, aged 8 from North Yorkshire, who wants to stop factory pollution and global warming with an idea to help clean polluted water using algae ponds.
- Llewyn, aged 9 from Glasgow, who had an idea to invent compostable glasses which allow people to see how much carbon dioxide is in the air and encourage them to make steps to prevent pollution.
- Ruby, aged 10 from Devon, who entered with an idea to reduce waste with solar powered vans to give people access to refill services.
- Annie, aged 12 from Milton Keynes, who had an idea to help save coral reefs by supplying them with nutrients and calcium with ‘ocean bursts’, an idea which came from bath bombs.

Blue Peter received almost 2000 entries from all over the UK with children submitting their ideas and inventions to help protect and restore our planet in the future. Children were invited to submit an original idea aimed at achieving one of the five ‘Earthshots,’ the aspirational environmental goals established by The Earthshot Prize: Fix our Climate, Protect and Restore Nature, Clean our Air, Revive our Oceans and Build a Waste-Free World.
