While it's great to see manufacturers taking their eco duties seriously with a number of 'green' handsets, one in particular stood out from the crowd. The Sony Ericsson Elm is not only made predominantly from recycled plastic, the manufacturer has made a concerted effort to limit the amount of packaging used to box the product thus reducing transport related CO2 transmissions. In fact all of the Elm's packaging is made from paper making it 100% recyclable, while instead of a paper instruction manual, Sony Ericsson has opted for an e-manual instead. Even the charger is green, reminding you to unplug it when the phone is fully charged by a green light switching on, while the phone itself when then display a message reminding you to unplug the charger from the mains.
The LG GD510 Pop's packaging is made from recycled paper with soy ink printing while once the phone is fully charged it will beep and display a message reminding the user to unplug the charger, thus saving energy. LG also sells a solar-battery for the LG Pop, that provides two minutes 15 seconds talktime or up to 180 minutes of standby time from just 10 minutes under the sun. The pre-embedded Eco-tree and Eco-calculator in tune allows you to track how much you've reduced your CO2 emissions by using the solar cell battery.
By adjusting the LCD brightness and connectivity levels, you as the user can alter how 'green' the Samsung Wave is. Even without any adjustments, the Wave has a 40% lower power consumption in average pixel ratio compared to a more conventional mobile display, while the 900 hours talktime and 650 hours standby equates to a phenomenal battery life and means you'll be using less power to charge it every other day.
