Earth Hour 2015 observed globally from 8.30 pm to 9.30 pm local time

Earth Hour 2015 was observed globally on 28 March 2015 from 8:30 pm to 9:30 pm local time. The tagline for the global campaign was Change Climate Change. This was the ninth edition of the Earth Hour that started in 2007.

Earth Hour 2015 was observed across 172 nations and territories and around 1400+ iconic landmarks of the world switched off the lights.

Earth Hour is a global campaign with a simple message to switch off non-essential lights for one hour on the last Saturday of March between 8:30 and 9:30 pm. This is done as a commitment to the planet.

Earth Hour is organised by the World Wide Fund for Nature (WWF) since 2007 when it was first observed in Sydney, Australia.

Earth Hour in India
India joined the Earth Hour campaign in 2009 and over the years has seen an exponential growth in participation across cities, towns and even far-flung villages of rural India.

The brand ambassadors for Earth Hour in India are Arjun Kapoor (actor), Priya Mani (actress), Sania Mirza (Tennis player), June Maliah (actress), and Suresh Gopi (Malayalam actor).
