Every year, millions of people around the world count down to Earth Hour by doing one iconic thing: turning off the lights. The movement is always done once a year on the last Saturday of March. This year, the Earth Hour 2023 happened on Saturday, March 25, 2023.
Earth Hour was founded in 2007 by WWF and partners in Sydney, Australia, and has since grown to become the world’s largest grassroots environmental movement. Participants are encouraged to go beyond the symbolic lights-out action this year by learning about, reconnecting with, and assisting in the restoration of our environment. There are so many ways to celebrate Earth Hour: read up on biodiversity loss, spend some quiet time in nature, pick up litter, or plant native trees.
The hour of darkness takes us away from the hustle and bustle of our daily lives and allows us to reflect on the one home we all share. There has never been a more critical time to come together and take action for our collective future in the face of accelerating biodiversity loss and climate change. It has grown over the last 16 years to become the world’s largest grassroots environmental movement, inspiring individuals, communities, businesses, and organizations in over 190 countries and territories to take action for our collective future.
Historically, Earth Hour has focused on the climate crisis; however, in recent years, Earth Hour has sought to address a wide range of issues confronting people and the planet. The movement acknowledges the role of individuals in solving the world’s most pressing environmental challenges and demonstrates the power of millions of people working together toward a common goal.
