For the past few years, Earth Hour has made an impact on the world thanks to the power of the crowd. But for 2014 with your help, we want to make an even greater one.

Come February 2014, we'll be unleashing something different, bigger and bolder than before.

We'll be unleashing Earth Hour Blue.
We'll be unleashing Your Power.
