Earth Hour

The world’s largest movement for the environment returns every year on time on the last Saturday in March. This is Earth Hour.

Organized by the World Wide Fund for Nature (WWF), the festival features nature-themed experiences that highlight the rapid loss of nature and its impact. Through workshops and activities, Earth Hour aims to reach thousands of people so that we become conscious citizens who make sustainable decisions on a daily basis.


The symbolic Earth Hour blackout will take place in 180 countries and territories around the world.

Taking home the message of sustainability, Earth Hour will be carbon neutral, zero waste, and feature sustainable solutions for large-scale events. These solutions include the elimination of disposable products, the use of reusable containers and bags, and a physical configuration created from recycled wooden pallets that can be disassembled and reused.

About Earth Hour

Earth Hour is WWF’s global environmental movement. Born in Sydney in 2007, Earth Hour has become the world’s largest grassroots movement for the environment, inspiring individuals, communities, businesses and organizations around the world to take tangible climate action for more than one of each.


More recently, Earth Hour has focused on raising awareness and inspiring conversations about why nature is important. The movement recognizes the role of individuals in creating solutions to the planet’s most pressing environmental challenges and harnesses the collective power of its millions of supporters to build a sustainable future for all.


What does it consist of?


Every year a voluntary electrical blackout is carried out, in which homes and companies are asked to turn off lights and other non-essential electrical appliances for one hour. With this symbolic action, the intention is to raise awareness in society to adopt measures against climate change, save energy and fight against the increasingly present light pollution in our places.


Join the largest global movement for the environment.
