Wales has marked its biggest Earth Hour yet, with wide political and public support for action on climate change.

To mark the campaign’s 10th anniversary, WWF Cymru invited supporters to take part in its ‘Message in a Bottle’ campaign, to demonstrate the strength of feeling for urgent national and global action to reduce greenhouse gas emissions.

A giant, eight metre sculpture, designed by artist Lulu Quinn, symbolising hundreds of messages gathered across Wales, was delivered to the Senedd steps as a focus for the national switch-off.

To mark the occasion, Welsh Music Prize nominee, The Gentle Good, together with singer songwriter, Catrin Herbert, gave an exclusive performance at the Senedd, broadcast on Facebook live – watch the video here.

Among the country’s iconic landmarks switching off were Caernarfon Castle, National Library of Wales in Aberystwyth, National Waterfront Museum in Swansea, and the Senedd and Principality Stadium in Cardiff.

Other support in Wales included:

  • For the second year, all 22 Welsh local authorities signed up
  • Support from 30 of the 60 Welsh Assembly Members
  • Over 300 schools
  • Universities include Bangor, Wrexham Glyndwr, Cardiff, Cardiff Met and Swansea.
  • Businesses include St David’s Shopping Centre, Ikea, John Lewis, Arriva Trains Wales, Howies and Admiral.
  • Organisations include Swansea City Football Club, Church in Wales, Cynnal Cymru, Welsh National Opera
  • Community events included Head 4 Arts holding four events in Caerphilly, Merthyr Tydfil, Torfaen and Blaenau Gwent, F.A.N Community Alliance in Neath ­­­hosting a candle and solar-lit meal, and at Ffwrn in Fishguard

Anne Meikle, Head of WWF Cymru said

“Our Message in a Bottle campaign has also captured the imagination of our Welsh politicians with half of all Assembly Members pledging their support. It is clear that tackling climate change is becoming more and more a priority issue for both the public and politicians - and this is something to celebrate. Big thanks go to the Arts Council of Wales and players of People’s Postcode Lottery for supporting this campaign.”
