O2 has launched an Eco ratings scheme that ranks mobile phones in terms of their environmental impact. LG and Palm are the worst offenders, with the Pam Pre+ and several LG handsets making up the bulk of the lower end of the scale. Meanwhile, Apple has refused to participate in the survey
O2′s survey of 65 handsets in regular us in the UK looks at various factors (packaging, materials, recyleability, etc) that define how a mobile phone impacts the environment and rates each on a scale of 1 to 5 (5 being the best). While no phone managed to score a perfect five, the Sony Ericsson Elm came out best with a near-saintly 4.3 out of 5.
