One Earth, One City, One hour
In Hong Kong, this year’s theme was “One Earth, One City, One Hour”. Hong Kong’s two electricity companies determined that during Earth Hour 2013, electricity consumption in Hong Kong dropped by 4.76 percent, representing a savings of 172 tonnes of carbon dioxide. It would require 7,478 trees to absorb this amount of CO2 over the course of a year.
WWF-Hong Kong encourages everyone to “go beyond the hour” and live a sustainable lifestyle by changing or modifying their daily lives. Even small changes, made daily, will add up to huge energy savings!
