What is Earth Hour?

WWF’s Earth Hour is the world’s biggest movement to protect our planet.


Every year hundreds of millions of people around the world in more than 7,000 cities in over 180 countries take part in this amazing global conservation movement. People do a wide range of things around the hour to show they care about our planet’s future. Millions choose to mark Earth Hour by going ‘lights out’ for 60 minutes at 8.30pm – a symbolic show of solidarity.



This year, we’re inviting all Australians to  #Connect2Earth, so that we can all work towards better understanding and appreciating the values of biodiversity and the current critical condition of our home and our planet. Being aware means that we can all take actions to protect our biodiversity and nature, it means we can live more sustainably, and expect the same of businesses and governments.


Will you join the movement? Let us know if you’ll be switching off for Earth Hour on Saturday, 30 March 2019 at 8:30pm local time, and help make a difference against climate change.


Find out how you can take part in Earth Hour, whether you’re an individual, school or business.

Earth Hour: Over 10 Years of Impact

Did you know Earth Hour was started right here in Sydney in 2007?


Since then, Earth Hour has become a global movement for change and in 2017 we were proud to celebrate 10 years of Earth Hour. 


Take a look at the impact Earth Hour has made on climate change action all over the world during the last decade.


Our actions today can change our tomorrow.

Earth Hour around the World

    In 2012, Russia legislated to protect its seas from oil pollution after receiving 120,000 petition signatures as part of Earth Hour’s ‘I Will If You Will’ Challenge.

    Since then, Earth Hour has been used by WWF-Russia to push for a commercial logging ban in protected forests, a moratorium on new oil fields in the Arctic and fundraise for the conservation of animals.

    According to the UN, Uganda loses 6000 hectares of forest each month. To halt this, WWF-Uganda in partnership with Standard Chartered Bank, The National Forestry Authority and local communities established an Earth Hour Forest in 2013. WWF-Uganda aims to plant half a million Indigenous trees across 2,700 hectares of degraded land.

    In 2013, Earth Hour helped in the creation of a 3.4-million-hectare marine park in Argentina. Known as the Banco Namuncurá, this marine protected area has significant natural and cultural value.

    The marine park was a result of the Fundacion Vida Silvestre, Patagonia Natural and the Wildlife Conservation Society, using Earth Hour to mobilise public support for the legislative bill.

    In 2014, an alliance of organisations campaigned under Earth Hour’s banner to raise awareness of the impacts of disposable plastic bags in the Galapagos. By the end of the year, the Government passed a resolution to ban plastic bags and styrofoam from the Islands.

    The win is expected to reduce the harmful impacts of plastics on the Galapagos’ unique animals.

    In 2014, Annette Kennewell attended Camp Earth Hour at Heron Island for community leaders, and went on to organise the People’s Climate Picnic in Moruya (NSW South Coast). She also helped establish the South Coast Health and Sustainability Alliance (SHASA) which is working on a community solar bulk buy for Eurobodalla homes and businesses.

    By 2017, SHASA will have 50 PV systems installed in the community.

    In 2017, Earth Hour Australia partnered with Solar Buddy to provide 500 portable lights to rural communities in Ethiopia. These lights were assembled by students, teachers, corporate partners, and staff. Charged by the sun, they provide many hours of light to help students in-need with their studies, as well as replacing carbon-intensive kerosene lamps.

    In 2018, the program will support communities in Papua New Guinea.
