In 2014, Earth Hour broke all records of mass participation by mobilising hundreds of millions of people to become everyday super heroes for the planet and was celebrated in 162 countries and territories and over 7000 cities and towns.
More than just a lights off event, over 60 local Earth Hour campaigns achieved remarkable environmental outcomes all across the world.
The Washington National Cathedral will turn out their lights for Earth Hour:
On Saturday, March 28, from 8:30–9:30 pm, the Cathedral joins the World Wildlife Fund and others worldwide in turning off the lights to raise awareness of climate change with Earth Hour 2015.
