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 one hour at 8:30pm on March 31st 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!

Sign up to participate and turn off all non-essential lights at 8:30pm, your local time.
