What is Earth Hour?

Started in 2007, Earth Hour has been known for the “lights off” moment, with individuals from around the globe switching off their lights to show symbolic support for the planet and to raise awareness of the environmental issues affecting it.

A huge ripple effect

We can use the power of the people to turn a single Earth Hour into thousands and millions of hours of action and awareness, creating a domino effect of impact that continues well beyond the 60 minutes.

A need for change

The next 7 years are crucial to all our futures – we have to stay under the 1.5°C climate threshold to avoid irreversible damage to our planet, and we need to reverse nature loss by 2030. Ending the decade with more nature and biodiversity.

You can take part too

Earth Hour believes that each and every one of us has the power to make a positive impact on our planet, but it’s up to us as individuals to decide how we do so. So if you’ve thought of another way to give your hour for Earth that’s not listed below, go for it! 

Learn more

A little extra knowledge can go a long way – awareness is after all the first step before action. So spend the time and the hour deepening your understanding of our planet, the threats we face, and what you can do to help!

Reconnect with nature

Spending time in nature is one of the best ways to appreciate our planet and be inspired to protect it – so embark outdoors with your friends and family! Make sure you are safe.

Spread the word

Earth Hour has always been powered by the people – and you don’t need to be famous to inspire others to act.  So whether it starts with your significant other, your children, or your community, you are playing a crucial role!
