Earth Hour is a global initiative organized by the World Wide Fund for Nature (WWF) to raise awareness about climate change and environmental sustainability. Participants are encouraged to turn off non-essential lights for one hour to show support for tackling environmental issues and promoting energy conservation. Earth Hour symbolizes a collective effort to take action and protect the planet.
The first Earth Hour took place in Sydney, the capital city of New South Wales, Australia, in 2007. It was an idea developed by newspaper The Sydney Morning Herald and WWF (World Wide Fund for Nature/World Wildlife Fund). For that first ever Earth hour, 2.2 million homes and businesses in the Sydney area switched off their lights for the period of one hour.
Earth Hour in Newfoundland and Labrador starts at 8:30 PM local time on the last Saturday of March. For 2024, this means it will occur on March 30th. During this hour, individuals and businesses are encouraged to turn off non-essential lights to raise awareness about climate change.
Earth Hour was created in 2007 by World Wildlife Fund (WWF) in Sydney, Australia. It was initiated by WWF and partners as a lights-off event to raise awareness about climate change and energy conservation.
