Every March, millions of people come together for one hour to show care for the planet, our shared home.

Lights of iconic landmarks across the globe go out in a stunning display of solidarity for Earth. People also join from their homes and local communities across towns and cities in over 192 countries and territories. 

Earth Hour began in 2007 as a small grassroots movement in Sydney, Australia. In 2020, Earth Hour went fully digital for the first time in the United Kingdom.

Why do we do this? Our climate is changing. Nature is declining. There are now extreme weather happenings: Sinking cities and homes, deforestation, ocean pollution and depleting wildlife. Human activities have been the main driver of climate change. We are also paying its price.

Switching your lights off 60 minutes once a year actually helps fight the climate crisis and address the drastic loss of diversity of life on Earth. It may not be much, but it’s a step toward making a difference.

In 2024, the world gave more than 1.4 million hours for Earth Hour. So, there’s no excuse to not spend 60 minutes of your time doing good for the planet.

Earth Hour makes a change, even for just one day. Small actions can make a big difference.
