The Sony Ericsson Elm has been ranked the most sustainable handset on sale at O2 according to the eco-rating system set up by the mobile phone operator.
Six manufacturers are included in the list but notable absentees include RIM and Apple; the Elm scored 4.3 out of 5, which is one of the many eco-friendly phones Sony Ericsson sells as part of the Greenheart family.
The Elm is made up of recycled plastics, comes with a green calculator, e-manual, low power chargers, minimal packaging and free from environmentally harmful chemicals. It is also one of six Sony Ericsson models in the top 10 of most ecofriendly phones.
O2 has it on a £10 per month contract and it can be had for as little as £100 per month, not bad for a model that comes with a 5-megapixel camera and has a noise shields for clear calls.
LG's Etna came up last according to with a rating of 2.7 while five other LG phones made up the list of least eco-friendly phones with scores of 3.2 or less.
But then, the Korean company has just bagged the title of "European Green Mobile Phone 2010-2011" with the best selling LG GD510; puzzling to say the least.
