Earth Hour 2015 – Lights out for climate protection

Trodat and the environment

​Since 2007, the WWF has called on all the people of the world to turn their lights off for one hour, thus creating a symbol for climate protection and saving the planet: this year's Earth Hour day was 28th March 2015.


Earth Hour 2015 – Lights out for climate protection
Back in 2007, in Sydney, Australia, around 2.2 million people switched their lights off. In 2011, for example, several hundred million people took part in approx. 5,200 cities in 135 countries around the world, and in 2014, 7,000 cities and communities in 163 countries participated: thus, Earth Hour was and is the largest campaign for the global climate of all time.
In 2014, all the state capitals and many towns and cities in Austria joined in: In all the state capitals, the lights of around 100 of the most recognisable landmarks were switched off for an hour. Companies, hotels and countless households also took part.
This year's Earth Hour took place on Saturday 28th March 2015 from 20:30 until 21:30 (local time in Austria): and the Trodat site in Wels, Austria also took part in this year's Earth Hour with a visible sign for climate protection – the huge LED light façade on Linzer Straße remained dark for Earth Hour 2015.
