The largest global environmental movement Earth Hour returns for its 19th edition with the Biggest Hour for Earth as it unites millions around the world in celebration of our planet
- Earth Hour 2025 returns by providing 60 minutes of global unity around the world, in support and celebration of our planet. Earth Hour serves as a beacon of positivity, hope, and inspiration to rally as many people as possible.
- The stakes have never been higher. The past year was the hottest on record—capping off the hottest decade, with the hottest seas ever recorded. We’ve witnessed historic wildfires, storms, and droughts as well. Our world is in peril and we are rapidly approaching dangerous tipping points beyond which key ecosystems may never be able to recover.
- Building on the incredible momentum of 2024, when we reached a milestone of 1.5 million hours, we aim to surpass that number this year to 2 million hours by inviting individuals to ‘Give an hour for Earth’ on earthhour.org/giveanhour by doing something they love, big or small, every contribution counts.
LOCATION – From 8:30 pm local time on 22nd March, WWF’s Earth Hour, the world’s largest grassroots environmental movement, returns for its 19th edition with the ‘Biggest Hour for Earth’ in support and celebration of our planet. Earth Hour serves as a beacon of positivity, hope, and inspiration to rally as many people as possible in over 180 countries and territories.
Since its creation in 2007, Earth Hour has been known for its “lights off” moment. As landmarks and homes across the world switch off, supporters are also invited to symbolically switch off and 'Give an hour for Earth’, spending 60 minutes doing something - anything - positive for our planet. In 2024, over 1.5 million hours were given to our planet by supporters around the world.
Kirsten Schuijt, Director General, WWF International: “The stakes have never been higher. The past year was the hottest on record—capping off the hottest decade, with the hottest seas ever recorded. We’ve witnessed historic wildfires, storms, and droughts as well. Our world is in peril and we are rapidly approaching dangerous climate tipping points beyond which key ecosystems may never be able to recover. Earth Hour is a powerful reminder of the urgency to act while we still can. It is not just about switching off lights; it’s about switching on a global movement for change. By engaging individuals, communities, and businesses, we can create a collective force that drives real impact and inspires hope for a sustainable future.”
Through the Hour Bank, Earth Hour invites everyone, everywhere to find the most enjoyable ways to give an hour for Earth. Whether it is cooking a sustainable meal at home, catching a nature documentary, taking a mindful walk through the woods to bask in nature and feel the earth, or engaging in a home scavenger hunt to identify and swap out unsustainable products with eco-friendly alternatives, there are myriad options to choose from. The Hour Bank provides a list of activities and events based on participants' lifestyle interests and preferences, from food and fitness to art and entertainment.
The "Give an hour for Earth" call-to-action makes participation even easier and fun, encouraging individuals not only to switch off lights symbolically but also to take 60 minutes to do good for the planet by doing something they love.
Yves Calmette, Senior Director, Brand and Network Communications, Earth Hour Global: “Earth Hour is all about making environmental action accessible, enjoyable, and meaningful. By aligning our actions with people’s passions and interests, we can inspire even more individuals to join the movement. The Hour Bank is designed to show that everyone can contribute to protecting our planet, no matter where they are or what they love to do. Building on the incredible momentum of 2024, when we reach a milestone of 1.5 million hours, we aim to surpass that number to 2 million hours this year. Together, we can create a brighter, more sustainable future.”
Earth Hour is more than a moment; it's a movement that has continued to inspire and mobilise people globally, reminding us of our collective responsibility to create a more hopeful and resilient future for our planet.
