Earth Hour 2012

Dare the World to Save the Planet

We only have one planet.  You can help protect it. Participate in the world’s largest single campaign for the planet: Earth Hour. It starts by turning off your lights for an hour at 8:30 pm on March 31, 2012 in a collective display of commitment to a better future for the planet.  Think what can be achieved when we all come together for a common cause.

Go Beyond the Hour

This Earth Hour we invite you to do more than switch off your lights. We want you to dare the world to save the planet.
"I Will If You Will" is a simple promise and a challenge. Dare anyone (your Facebook friends, co-workers, celebrity crushes) to accept your challenge and help protect the Earth or accept the challenge of someone else.
Visit "I Will If You Will" to see all the challenges and create your own.

The Earth Hour City Challenge encourages cities to prepare for the costly impacts of climate-related extreme weather and to reduce their carbon footprint. You can be an integral part in this challenge. Send a letter to your mayor, urging them to prepare for a changing climate. Check out our map to see how your city is at risk from extreme weather.

Why is your participation important?

Our future depends on it.  Across the world, biodiversity and natural habitats are disappearing at a greater rate than ever before.  We are depleting the earth of wild animals, water, wood and other natural resources faster than they can be replenished; polluting and altering natural habitats and changing the entire planet's climate.

Things will only worsen if we continue in the same direction.
Earth Hour raises awareness of sustainability issues.  But there’s more to it than switching off lights for one hour once a year.  It’s about giving people a voice and working together to create a better future for our planet.
