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 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.

Why get involved?
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.

Take this opportunity to send a reminder to our leaders that we need to protect our planet by signing up for Earth Hour. Go beyond the hour by reducing your individual impact on the planet.  The actions you can take are endless and are things you can do every day.


More than 5,200 cities and towns in 135 countries worldwide switched off their lights for Earth Hour 2011, sending a powerful message for action on climate change. It also ushered in a new era with members going Beyond the Hour to commit to lasting action for the planet. Without a doubt, it’s shown how great things can be achieved when people come together for a common cause.
