Earth Hour 2021 was celebrated virtually on Saturday, 27 March at 8.30pm local time. It took place ahead of key international meetings where world leaders came together to talk about climate action, sustainable development and how to stem nature loss.

Earth Hour is the largest global grassroots movement for the environment, bringing together millions of people, businesses and leaders from around the world. The movement has been celebrated in South Africa and the world over for more than a decade. “This year, we called on our supporters to shine a spotlight on some of the most pressing environmental issues of the day by signing up as a ‘nature hero’ for the hour,” says Dr Morné du Plessis, CEO of WWF South Africa.

On the night of Earth Hour, WWF South Africa shared a special Earth Hour 2021 campaign video narrated by award-winning actor, director and playwright Dr John Kani and encouraged participants to share this on their social media platforms. The video showed the links between pandemics, climate change and pollution, and the role of nature in addressing these challenges.

The theme for Earth Hour 2021 focuses on ‘Climate Change to Save Earth’. This year, key political decisions will be taken by world leaders on nature, climate change and sustainable development which will set the course for the future. Several catastrophic incidents last year, including extreme weather events, devastating wildfires and the Covid-19 outbreak, proved that preventing nature loss is imperative for safeguarding the future.

“Healthy natural ecosystems are the cornerstone of thriving, equitable and sustainable societies,” says Marco Lambertini, director general at WWF International. “2021 is a crucial year for humanity. As the world tries to turn the tide and recover from the ravages of the Covid-19 pandemic and rebuild itself, we need to put nature at the centre of our recovery efforts to future-proof our economies and societies. Earth Hour is a critical moment for individuals, leaders, and environmentalists to unite and call for urgent action to reverse nature loss and secure a nature-positive world by 2030.”

Earth Hour is WWF's flagship global environmental movement. WWF is an independent conservation organisation, the mission of which is to stop the degradation of the earth's natural environment and to build a future in which humans live in harmony with nature, by conserving the world's biological diversity, ensuring that the use of renewable natural resources is sustainable, and promoting the reduction of pollution and wasteful consumption.
