March 20, 2024 /3BL/ - On March 23rd at 8:30 pm local time, WWF’s Earth Hour will return to unite millions worldwide in support and celebration of our planet. In an increasingly divided world struggling with the impacts of climate change and biodiversity loss, Earth Hour provides much-needed positivity, inspiration, and hope.

Since 2007, Earth Hour has been known for its iconic “lights out” moment, with landmarks and homes worldwide switching off their lights. This year, while major landmarks go dark to celebrate Earth Hour, WWF encourages individuals to 'Give an Hour for Earth' by spending 60 minutes participating in any eco-positive activity from now until Earth Day on April 22nd. An interactive online tool will suggest activities for various lifestyles and interests, and participants can log their contribution to the national and global ‘Hour Bank’.

Katy Fenn, Director of Brand Engagement and Education, said: “From food and fitness to art and entertainment, there’s an activity for everyone in the Hour Bank, and we are aiming to bank 100,000 hours here in the United States. This new campaign approach proves that environmental action can be easy, fun and impactful. By expanding participation to those who are not yet environmentally engaged, we hope to raise awareness and spur collective action in protecting our planet.”
