23 MARCH 2025 – At 8:30 pm local time on 22nd March, millions of people around the world came together for Earth Hour in an inspiring show of unity and commitment to our planet. As of today, nearly 3 million hours have been given for Earth,with Earth Hour also trending in over 31 countries, reaffirming Earth Hour as a powerful global movement for environmental action.

A global moment of unity for the planet
This year’s Earth Hour also served as a stark reminder of the twin crises we face—climate change and nature loss. Nature is disappearing at an alarming rate, and this past year was officially the hottest on record, marking the end of the hottest decade and witnessing unprecedented ocean temperatures. The urgency to act has never been greater. In response, supporters over 118  countries and territories collectively dedicated nearly 3 million hours, demonstrating that individual and collective action can create real impact.

Earth Hour 2025 once again served as a beacon of hope and inspiration, bringing together individuals, communities, businesses, and institutions. Participants engaged in meaningful activities aligned with their passions—whether reconnecting with nature, restoring the environment, learning about the planet, or inspiring others to care for our planet.

Key public figures lent their voices to the cause, including United Nations Secretary-General António Guterres, the British Royal Family, Colombian model Ana Sofía Henao, Mexican actress Michelle Manterola, Pakistani adventure athlete Samar Khan, Bollywood actress Dia Mirza Rekh, South Korean actress Park Jinhee, and Japanese basketball team Nagoya Diamond Dolphins, among many others. Their support helped amplify Earth Hour’s message of collective action and responsibility.

Landmarks across the world switch off in solidarity
From iconic landmarks to small communities, Earth Hour’s signature switch-off moment was observed across the globe. Some of the world’s most famous landmarks dimmed their lights in a symbolic act of environmental solidarity, including the The Sydney Opera House, Shanghai Tower, Seoul Tower, Kuala Lumpur Twin Towers, Burj Khalifa, The Colosseum, Eiffel Tower, The London Eye, The Empire State Building, The UN Headquarters, Niagara Falls and Christ the Redeemer. 

A growing movement for a sustainable future

António Guterres, Secretary-General of the United Nations, reinforced the urgency of action: “Earth hour is about solidarity, hope, and the power of collective action. Human-made climate calamity is here and now. ...We’ve just had the hottest year, the hottest decade, and the hottest seas on record. And we’ve seen historic fires, storms and droughts as a result. Moving away from polluting fossil fuels – the leading cause of this chaos – towards renewable power holds immense promise for us all – it’s healthier, cheaper and more secure. So please, join us  ... And use your power to push for a better world for us all."

Kirsten Schuijt, Director General of WWF International, added: “I am deeply moved by the incredible spirit of millions of people around the world who have come together for Earth Hour. This movement is a testament to the power of collective action and the hope we share for a healthier planet. To everyone who gave an hour for Earth, thank you. Your actions, big and small, inspire us all. In times when the world feels increasingly divided, Earth Hour reminds us that we can unite for a common cause, something greater, our shared home, the planet. Together, we are making a positive impact toward a more sustainable future.”

Looking Ahead to Earth Hour 2026
Earth Hour continues to evolve, inspiring millions to take tangible actions beyond the hour. The next edition will take place at 8:30 pm local time on Saturday, 28 March 2026, calling for even greater global participation.

Global Highlights: Earth Hour 2025 in Action
This year’s Earth Hour saw a diverse range of activations around the world:

  • WWF-Cambodia joined forces with the Ministry of Agriculture, Forestry and Fisheries (MAFF), the Fisheries Administration, and conservation partners for the Mekong Dolphin Swim, a 120km relay to raise funds and awareness for the critically endangered Irrawaddy dolphins. The team documented dolphin sightings, removed abandoned fishing nets, and engaged riverside communities in Stung Treng and Kratie. The local event also featured Cambodian singer KAI, several private sector partners, and community members from Stung Treng, Kratie, and beyond.”
  • WWF-Singapore held its flagship Earth Hour festival at Sentosa Sensoryscape, the island's newest attraction, and brought sustainability to life through interactive exhibits, workshops, and performances, celebrating Singapore’s SG60 milestone. In conjunction with World Water Day, the festival engaged visitors in water conservation efforts and hands-on activities like solar light assembly and sustainable food workshops. 
  • WWF-China spearheaded one of the largest nationwide sustainable living and sustainable cities initiatives, driving real impact across more than 160 urban centers in China. Through corporate pledges, educational workshops, cross-industry expert sharing sessions, and a switch-off ceremony in Hengqin City.  The campaign mobilized many celebrities including Lin Gengxin. More than three million people took concrete steps toward reducing their carbon footprint and protecting nature.
  • WWF-India united Earth Hour 2025 and World Water Day under the #BeWaterWise campaign, spotlighting the need for water conservation. With only 4% of global freshwater for 1.4 billion Indians, the campaign and its influencers, including actor and UN Environment Goodwill Ambassador Dia Mirza, Chess Grandmaster and WWF-India Education Ambassador Viswanathan Anand, and Grammy winner Ricky Kej, urged individuals to adopt water-conscious habits year-round. Earth Hour Festival 2025 drew Delhi residents with art, music, and architecture, while also honouring community stewards of conservation.
  • WWF-Germany’s Brandenburg Gate sent a powerful message to politicians and decision makers. The first ever Earth Hour choir – the Earth Hour Voices – was formed for this special event, singing ten songs for our planet. The musical performance was powered by cycling energy from the Wheel Divas, a female cycling team from Berlin, who kept the screen running for everyone to see the lyrics. There was also an interactive discussion led by WWF experts alongside host Diona Bathily, focusing on climate policies and asking for the new German government.
  • WWF-Madagascar rallied youth, businesses, and policymakers for Earth Hour 2025 to fight deforestation through a month-long digital campaign on reforestation, sustainability workshops, and climate storytelling. The first-ever Earth Hour Game Festival in Antananarivo was held in collaboration with Alliance Aika and local youth coalitions Move Up Madagascar and Namako ny Tany, inspiring young leaders to take a stand and protect Madagascar’s forests.
  • Across Africa, many communities tackled water conservation, wetlands restoration, and waste management. In Namibia, Zimbabwe, Tanzania, and the Republic of Congo (RoC) tree-planting initiatives in Kavango, Hwange, Kitenden, and Dia respectively helped restore ecosystems and protect water sources. Namibia’s Youth in Conservation (YiC) Indaba, Zimbabwe and RoC’s school-led conservation efforts, and Tanzania’s Nature Caravan empowered young leaders to drive lasting change.
  • WWF-Chile merged music and climate action with Earth Beats: An Eternal Sound, an orchestral piece by Tomás Brantmayer. Performed by the Orquesta de Cámara de Valdivia (OCV) and Orquesta Clásica de la USACH, it featured the final song of the extinct Kauaʻi ʻōʻō bird, with a special performance by the renowned violinist Sylvia Huang, highlighting the urgency of biodiversity conservation.
  • WWF-Ecuador, in partnership with Ecuador’s National Football Federation, launched We Are Playing the Game of Our Lives, urging football fans to reduce single-use plastics in and outside of football stadiums. Internationally renowned players like Moises Caicedo (Chelsea FC), Piero Hincapie (Bayern Leverkusen) and William Pacho (Paris St Germain) will also be joining efforts in this campaign, which debuted at the Ecuador vs. Venezuela match and will continue throughout the year.
  • WWF-US linked Earth Hour 2025 with World Water Day, launching the Give an Hour for Earth challenge. Influencers and streamers including Tara Stiles, Cathy Madeo, Faith Hunter, Travis Eliot and Koya Webb engaged audiences through live sustainability challenges, climate talks, and fundraising.
