Mobile handset leader Nokia has promised to halve the power consumption of battery chargers as well cut the company's overall energy use.
In a series of carbon reduction pledges as it joined the WWF Climate Savers program, Nokia will also ensure that 50% of the electricity that powers the company's plants and offices will derive from green sources.
Nokia said it will reduce by 50% the average amount of energy used by battery chargers in "no-load" mode—when they are plugged into the mains but not charging a mobile phone. No-load power consumption has fallen by more than 50% in Nokia chargers in the past nine years, and they now need just one-tenth of the power used by the most common chargers, Nokia says.
The company aims to reduce the average no-load power consumption by another 50% by the end of 2010. It will also remind consumers to unplug the charger from the electricity outlet once the phone has been fully charged.
Nokia said it reduced the company's overall global energy consumption by 3.5% though energy-efficiency programs. It is targeting further savings between 2007 and 2012 of 6% compared to 2006 levels.
It uses green electricity to power 25% of the energy used by its facilities worldwide and will increase this to 50% in 2010.
