Sony Ericsson has launched two new green mobile phones, which it claims reduce CO2 emissions by 15 percent compared to other Sony Ericsson handsets.

The C901 GreenHeart measures 105x45x133mm and weighs 107g. Only available in white, the handset features a 2.2in 240x320 display, a 5Mp camera with 16x zoom and xenon flash, integrated GPS, media player and Bluetooth connectivity.

The Sony Ericsson Naite comes with a 2Mp camera. The phone features the same 2.2in display as the C901 GreenHeart, as well as Bluetooth connectivity, and measures 108x47x12.6mm. It is available in red or silver and also comes with a Carbon Footprint calculator so consumers can work out just how much CO2 they are using.

Sony Ericsson says the CO2 emissions of both handsets have been reduced by shipping with an e-manual rather than a paper manual. Furthermore, at least 50 percent of the phones' casing is made from recycled plastics. The Sony Ericsson Naite will also come bundled with an EP300 Greenheart, which is a low-power charger

Sony Ericsson has also unveiled the MH300 GreenHeart headset, which is compatible with the C901 GreenHeart and made from 100 percent recycled plastic.

The C901 Greenheart, the Sony Ericsson Naite and the MH300 GreenHeart headset will be available in Q3 this year. No pricing details have been released yet.

The Sony Ericsson C901 GreenHeart emits 15 percent less C02 emissions over the course of a year than other Sony Ericsson handsets
