This year’s Earth Hour is celebrated on Saturday, March 28, again between 8:30 and 9:30 pm local time.

In 2015, the tagline for the global campaign was Change Climate Change, returning to the movement’s original focus to initiate citizen action on global warming.

Earth Hour is a worldwide event organized by the World Wide Fund for Nature (WWF). It is held worldwide annually encouraging individuals, communities, households and businesses to turn off their non-essential lights for one hour, from 8:30 to 9:30 p.m. on the last Saturday in March.

On March 27, a day before the event, over 170 countries and territories have confirmed their participation; with more than 1200 landmarks and close to 40 UNESCO world heritage sites set for the switch off.

For the second year running, Earth Hour Blue aims to raise funds for WWF organized climate focused projects on a crowdfunding platform. This year, crowdfunding projects include solar light distribution in the Philippines and India, and wildlife based projects from Colombia, Uganda and Indonesia.
