Earth Hour 2023: The Biggest Hour for Earth

Earth Hour

Each year, millions of people across the world count down to Earth Hour and take one iconic action: switching off the lights. The hour of darkness pulls us out of the busyness of our daily routines and allows us to reflect on the one home we all share. The earth!

In the face of accelerating biodiversity loss and climate change, there has never been a more crucial time to come together and take action for our collective future.

How Earth Hour began

Earth Hour was first launched in 2007 by the World Wildlife Fund (WWF) and partners in Sydney, Australia. Since then, it has since grown into the largest global grassroots movement for the environment. This year, WWF are encouraging people to go beyond the symbolic lights-out action by learning about, reconnecting with, and helping restore our environment. They are asking us to read up on biodiversity loss, spend some quiet time in nature, pick up litter, or plant native trees. In short, there are so many ways to celebrate Earth Hour.

“For 16 years, Earth Hour has engaged millions of people the world over with a simple ask to switch off their lights for 60 minutes. But its meaning has become so much more than that,” said Chris Conner, vice president of media and external affairs. “Nature needs us. People need us. Our climate needs us. Earth Hour is an opportunity for us all to come together, not only to celebrate everything our planet provides us, but also to protect it.”

Environmental challenges

Historically, Earth Hour has focused on the climate crisis, but more recently, it has strived to address a range of concerns facing people and the planet. The movement recognises the role of individuals in creating solutions to the planet’s most pressing environmental challenges and demonstrates the power of millions of people working together towards a common goal.
