On January 28, 2008, Nokia joined the WWF Climate Savers program with a pledge to build on its strong environmental record by improving energy efficiency and reducing carbon dioxide emissions across its business. The company is targeting a series of energy savings including halving the stand-by energy used by its mobile phone chargers, using green electricity to power 50 percent of its facilities by 2010 and reducing the overall energy needs of its sites by 6 percent by 2012.
Nokia's WWF Climate Savers commitments build on the company's existing achievements in increasing energy efficiency. The targets include:
Product energy efficiency
Around two-thirds of the energy consumed by a mobile phone during its use is lost when it is fully charged and unplugged but the charger is left connected to the mains, so called "no-load" mode. Over the last nine years Nokia has reduced the average no-load energy used by its chargers by more than 50 percent and its best-in-class charger needs just one-tenth of the power used by the most common chargers.
Nokia aims to reduce the average no-load power consumption by another 50 per cent by the end of 2010. It will also roll out reminders for consumers to unplug the charger from the electricity outlet once the phone has been fully charged across its product range by the end of 2008.
Offices and sites
From 2003 to 2006 energy saving projects in Nokia facilities in Europe, the Americas, and China reduced the company's overall global energy consumption by 3.5 percent. Nokia is now targeting further savings between 2007 and 2012 of 6 percent compared to 2006 levels.
Nokia currently uses green electricity for 25 percent of the energy needed to run its facilities worldwide. The company plans to increase this to 50 percent in 2010.
