We've added newer rankings for both mobile and smart phones, but left the original ones here for those looking to reuse an older unit.

Older and Undated Ratings

[1] Greenpeace's assessment of PVCs/BFRs elimination (Jan 10)

[2] US carrier Sprint has developed criteria for its "Sprint Device Eco-logo" and offers complementary features like more sustainable packaging and "Eco-friendly Accessories".

[3] CalFinder (Aug 09), a site for solar contractors, offers a one-paragraph description of green features.

[4] Apple has a number of sustainability features for its iPhone and publishes life-cycle CO2e analysis.

[5] Nokia's approach: "There's no need to look for a device with a green sticker - all Nokia devices come with eco improvements."

[6] The Greenpeace Guide to Greener Electronics does not rank individual products, rather, it ranks consumer electronics companies according to policies on toxic chemicals, recycling and climate change. Vertatique's tracking of Greenpeace's rankings over the years shows Nokia and Sony Ericsson to be consistent top performers.

[8] Greenpeace's Green Electronics Search (Dec 08) ranks mobile phones and smart phones/PDAs on 25 criteria, then boils them down to a 10-point scale. The above-listed phones scored from 5.2 to 5.5

[9] The Daily Green's "The Greenest Cell Phones" (Feb 09) offers no methodology, but the author does add an important warning about the e-waste implications of a gratuitous upgrade to green.

[10] The Environmental Working Group's cell phone electromagnetic radiation database lists of 10 "Best Phones"and 10 "Best PDAs/Smatphones". In addition to the phones listed above, EWG also includes Sanyo Katana II and Helio Pantech Ocean, and Wing HERA110 on its "best" lists.

[11] UK mobile services provider Telefónica O2's "Eco rating"of 4.0 or better out of 5.0 for the phones they sell from participating manufacturers Nokia, Sony Ericsson, HTC, LG, Samsung and Palm. O2 publishes detailed rating methodology developed by Forum for the Future.

[12] IDC has ranked "10 key mobile device manufacturers" using "five criteria (packaging, materials, energy, end-of-life program, and overall sustainability efforts)." The top 5 are Nokia, Sony Ericsson, Apple, LG and Samsung. The bottom 5 are Motorola, Palm, Kyocera/Sanyo, RIM (Blackberry) and HTC. (Sep 2010)

[13] Good Guide rates 500+ models on a 10-point scale in Health, Environment, and Society. These units, which received 9.0 in the Environment category, also where among the tops overall.

[14] Greenpeace Survey rates products submitted by participating manufacturers on a 10-point scale. The hypothetical score of a "fictional product that combined the best features of all submitted products within each category" is 8.18 for mobile phones and 7.92 for smart phones. We report models scoring 5.0 or better; the score is shown in parenthesis.

[15] Nokia is the only mobile manufacturer to make the top 20 in Vestas' Corporate Renewable Energy Index [CREX] 2011, ranking #16 for RE as a percentage of energy consumption and #11 in total RE procurement.

Our experience with mobile/smart phones is typical of the challenges sorting through green ratings of electronics products and companies. The lack of good information is also hampered by the lack of mobile phone listings from the European ecolabels.

We are unaware of any volume buyer of mobile devices (business, government, or education) that significantly weights green criteria in its purchasing decisions. Please comment below if you know of green-oriented volume purchasers.

Take a look at who are the greenest telecom providers.

@ecologee told me in June 2010 that he has been using his Samsung Crest E1107, an inexpensive solar-powered GSM phone, for a couple of weeks now without plugging into the grid. His objective is to get through the summer without doing so. Getting through the short days of the German winter will be more of a challenge, as the phone is limited to 5-10 minutes of talk time for 1 hour of solar charging. The E1107 Crest, available in much of the world but not North America, offers a number of features, from a flashlight to an FM radio, that would make it attractive to those traveling off the beaten path . . . as long as they can find enough power for all those features.

For those looking for greener approaches to charging their existing units, blogger Kathryn Vercillo offers 10 solutions, ranging from solar to stored vampire power.

Update 2011.04.01
French company Wysips claims to have a solar film that can be used as a display on a mobile device to keep it charged longer. Engadget review.
