Started by WWF and partners as a symbolic lights-out event in Sydney in 2007, Earth Hour is now one of the world's largest grassroots movements for the environment. Held every year on the last Saturday of March, Earth Hour engages millions of people in more than 180 countries and territories, switching off their lights to show support for our planet.
But Earth Hour goes far beyond the symbolic action of switching off - it has become a catalyst for positive environmental impact, driving major legislative changes by harnessing the power of the people and collective action.
Earth Hour est un mouvement ouvert et nous invitons chacun, quel qu'il soit, à prendre part et à contribuer au développement de notre mission, qui a pour ambition de réunir les individus afin de protéger notre planète.
In 2007, we encouraged people around the world to switch off their lights to call attention to climate change. More than a decade later, the climate crisis remains, made worse by another urgent threat: the rapid loss of biodiversity and nature.
Natural systems are vital for all our futures – and yet, the rate of global loss of nature during the past 50 years is unprecedented in human history. Nature not only provides us food, water, clean air, and other services worth over US$125 trillion a year – it is also one of our strongest allies against climate change. Protecting nature is one of the most immediate, powerful, and cost-effective solutions to the climate crisis.
Today, Earth Hour aims to increase awareness and spark global conversations on protecting nature not only to combat the climate crisis, but to ensure our own health, happiness, prosperity and even survival.
2021 presents an unmissable opportunity. In 2021, world leaders will come together during key global conferences and forums to set the environmental agenda for the next decade and beyond. Crucial political decisions will be made on climate action, nature, and sustainable development –- decisions that will directly affect the fate of humanity and our planet for years to come.
With your support, Earth Hour 2021 could be a spotlight moment that puts nature at the center of international conversations. Together, we can speak up and show world leaders and other decision-makers around the globe that nature matters and urgent action must be taken to reverse nature loss.
Chaque année, la planète entière fait à l'unisson le compte à rebours jusqu'à l'événement Earth Hour et son action emblématique : l'extinction des lumières.
Mais c'est bien plus que cela. C'est un symbole d'unité. C'est un symbole d'espoir. C'est un symbole de puissance dans l'action collective en faveur de la nature.
