We are 14 days away from the big 'switch off' and the number of organizations and individuals pledging their support for Earth Hour is increasing rapidly.
Globally, we have already exceeded our target of 1000 cities! 1,189 cities and towns across 80 countries are committed, with more coming on board everyday!
In Sydney, where Earth Hour began in 2007, every ferry in the city's harbour will even sound its horn at precisely 8:30pm to herald the beginning of Earth Hour in Australia.
Do your bit by spreading the word!
