BMHS join millions across the world for Earth Hour 2023 on Saturday 25th of March 20.30-21.30 GMT

WWF’s Earth Hour is a global movement, which brings hundreds of millions of people together across the globe to unite and show that they care about the future of our planet, our one shared home. This year Earth Hour will take place on Saturday March 25th 8:30-9:30pm with homes, businesses and landmarks all over Wales due to take part.

Last year over 2,000 people in Wales took part in Earth Hour and this year WWF Cymru are once again asking people to be part of a movement for our world. The Senedd building, as well as the Pierhead and Ty Hywel are just a few of the iconic landmarks that are joining local authorities, businesses and organisations across Wales for Earth Hour this year.

Rhian Brewster, Head of Communications at WWF Cymru said:

“Earth Hour, one of the world’s largest environmental movements, reminds us that collectively even small actions can make a huge difference. Together, we have the power to shape a better future for people, nature and climate across Wales and the World.

We urge people in Wales to join the global movement for action on the climate and nature crisis this Earth Hour. This can include acts as simple walking in nature or tuning in to watch the new BBC nature series ‘Wild Isles’, to taking part in events held in your local communities. As individuals, communities, and countries we can all make positive changes to bring our world back to life.”

Nine out of ten people who take part in Earth Hour feel inspired to act for our planet. The impact of individual actions might seem small but collectively they can inspire change. Participating in Earth Hour reminds us that even small actions can make a significant difference.

2023 is an important year for change. By joining millions of people around the world and coming together on the night of Earth Hour, communities across Wales show they care about the future of our planet.

About Earth Hour:

Earth Hour, organised by WWF, is the global event inspiring millions across the world to take action and make a pledge to protect our brilliant planet, our home. Right now, we’re facing some of the biggest environmental threats ever seen. We’re the first generation to experience the effects of climate change – and we’re the last to be able to change it. We’re seeing our oceans suffocated by plastic and over-consumption decimate our forests, the lungs of the earth. Earth Hour shows what we can achieve when we all come together. In previous years, an estimated half a million people across Wales took part and iconic landmarks across the world - including the Wales Millennium Centre, the Eiffel Tower, and Sydney Opera House - switched off their lights for an hour to stand in solidarity with the planet. From Samoa to Tahiti, a record 188 countries and territories took part last year in the world’s biggest Earth Hour yet. The support for Earth Hour and WWF’s work more broadly has influenced climate policy, facilitated climate-friendly laws, such as a ban on plastic in the Galapagos Islands and supported the world’s first Earth Hour Forest in Uganda.
