March 18 - Wallenius Wilhelmsen Logistics' (WWL) will join thousands of offices of some of the world's leading corporations to support this year's Earth Hour "lights out" initiative for effective climate change action.

WWL will also be encouraging staff to individually join the expected hundreds of millions of others from every continent who will turn lights off for one hour from 8.30 pm on Saturday, March 27.

WWL will lead up to Earth Hour with an "energy efficiency week" in its main office in Oslo, with staff invited to "find wasted energy in the building", while WWL offices globally are being encouraged to plan their own activities for Earth Hour.

The companies are emphasising that while corporate efforts for Earth Hour are symbolic gestures, they also highlight the critical need for more action around climate protection.

Earth Hour is a global WWF climate change initiative. Earth Hour executive director Andy Ridley says: "The implementation of sustainable business practices is not just an environmental imperative, it's a commercial one, too. Earth Hour brings together cities, communities, businesses and individuals on the journey to positive action on climate change."

Individuals, businesses, governments and communities are invited to turn out their lights for one hour on Saturday March 27, 2010 at 8:30 PM to show their support for action on climate change. The event began in Sydney in 2007, when 2 million people switched off their lights. In 2008, more than 50 million people around the globe participated. In 2009, hundreds of millions of people in more than 4,000 cities and towns across 88 countries switched off their lights for one hour.
