Earth Hour Chennai

WWF started Earth Hour in 2007 to unite the world and make a stand against climate change. Today, Earth Hour is the world’s largest environmental movement for the planet that involves 178 countries and territories worldwide.

Earth Hour is more than an hour-long event. Our purpose is to empower an interconnected global community to achieve tangible environmental outcomes for our living planet.
