At last there is now an official plan to introduce a universal charger for mobile phones. The GSM Association (GSMA) together with the initial industry leaders such as 3 Group, AT&T, KTF, LG, mobilkom austria, Motorola, Nokia, Orange, Qualcomm, Samsung, Sony Ericsson, Telecom Italia, Telefónica, Telenor, Telstra, T-Mobile and Vodafone have pledge to introduce a universal charging solution (UCS) by 2012.
They have decided on micro-usb charger connection such as the one found on the Blackberry Storm. UCS chargers will also include a 4-star or higher efficiency rating, which is up to three times more energy-efficient than an unrated chargers.
There is also the potential to cut up to 50% of mobile phone chargers being manufactured each year, resulting in a potential drop of 13.6 to 21.8 million tonnes of greenhouse gasses each year.
