An hour in the dark for planet Earth

Every year, on the last Saturday of March, the world celebrates Earth Hour, a campaign organised by WWF. It started in 2007 in Sydney, Australia, with a symbolic gesture of turning out the lights for one hour to put the fight against climate change in the spotlight. Within 10 years it has become a world-wide movement, a call to positive action to protect planet Earth.

Countless people, organisations, local councils and companies join this symbolic petition. And companies such as Ferrovial must support this movement and spread its reach across the world, as well as working to reduce their own carbon footprint.

This very visual initiative raises awareness and reminds us all that we must each do our bit to fight climate change and achieve a better world for ourselves and for future generations.

Lights out for planet Earth

Between 20:30 and 21:30, 187 countries and territories joined the initiative; 3,100 landmarks and monuments turned off their lights; More than 3 billion impressions of the hashtag (#EarthHour2017, in Spanish #HoradelPlaneta) were obtained in the official campaign, being trending topic in 30 countries; And more than 350 influencers and ambassadors joined the conversation. Learn more about the highlights of #EarthHour here.

We took a look at the magical hour which brought so many people together.
