Have you signed the pledge for Earth Hour?
Today, hundreds of millions of people in more than 80 countries will unite to make a difference.
They will switch off their lights for one hour to send a powerful message: by working together, each of us can make a positive impact in the fight against climate change.
Turn off your lights today from 8:30-9:30 pm local time to join the worldwide movement as a call to action for climate change. Join us in the movement.
