O2 has announced it is to offer the Sony Ericsson Naite - the first of the manufacturer's "GreenHeart" range.

With its overall carbon footprint said to be reduced by 15%, the Naite is made from recycled and recyclable plastics, comes with a low power consumption charger, reduced packaging and an e-manual.

Features for the 3G handset include Wi-Fi, a 2-megapixel camera, stereo Bluetooth, an FM radio and an expandable memory up to 8GB.

The Sony Ericsson Naite is free on selected pay monthly tariffs and £97.86 on Pay & Go. As an added incentive Naite purchasers will be offered either a solar powered charger, a family Eco day out, an organic food hamper, or the option to give a donation to charity.
