Sony Ericsson has today unveiled its new range of environmentally friendly “GreenHeart” phones.

The first phones to be released under the GreenHeart banner will be the Naite and C901 which both boasts an array of green credentials, from 50% recycled plastic cases to on-board e-manuals – to cut down on paper usage, and optimized display light sensors that use less energy.

The Naite also comes with a low powered green charger while the C901 ships with a green headset. Both phones are designed to emphasize Sony Ericsson’s commitment to green issues, illustrated by it’s pledge to reduce CO² emissions by 15% for all its products by 2015.

Despite their undeniable green-ness, neither phone has been compromised in terms of features. The C901 candybar handset comes wielding a 5 megapixel camera with smile shutter, autofocus, geo-tagging and face detection while supporting EDGE and HSDPA networks for quick and easy web-browsing.
