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.
