The 2014 edition of Earth Hour will take place on Saturday 29 March and everyone around the world is invited to switch off their lights for one hour from 8:30 to 9:30 p.m., local time worldwide.

This symbolic global initiative organized by the World Wildlife Fund (WWF) started as a lights-off event in Sydney, Australia in 2007. Since then it has grown to engage over 150 countries and hundreds of millions of people.

The date traditionally coincides with the Spring and Autumn equinoxes in the northern and southern hemispheres respectively, which allows for near coincidental sunset times in both hemispheres, thereby ensuring the greatest visual impact for a global “lights out” event. 

For the last few years, the UN Headquarters in New York and many other UN offices around the world have been part of the many international landmarks participating in this initiative.

In order to demonstrate the UN’s commitment to support action on climate change, and in the lead-up to the Climate Summit, this year the UN is going the extra mile and turning off all non-essential lights within the UN complex in New York for three hours from 7:00 p.m. to 10:00 p.m. The offices in Geneva, Switzerland and many other UN locations worldwide will also participate.

Earth Hour recognizes that everyone’s involvement is needed in order to make a collective and positive impact. The initiative encourages individuals, businesses and governments around the world to be accountable for their ecological footprint.

By working together we can all contribute to the fight against climate change!
