Greenpeace's Guide to Greener Electronics, Oct. 2010

The 16th iteration of Greenpeace's ranking of technology companies finds Nokia and Sony Ericsson with commanding leads, and Nintendo still sunk in dead last.

HP, previously lambasted by Greenpeace over backtracking on a commitment to eliminate toxic chemicals from its products, rose from eighth place to fourth.

The improvement came after the IT giant launched PVC-free and BFR-free products and promised to phase out beryllium by next July. The firm's score in the league table went up from 4.9 to 5.5, although Greenpeace said the company must now move to phase out BFR and PVC from all its products.

Samsung enjoyed the biggest rise on the scoreboard, leaping from 13th place to fifth thanks to the removal of some penalty points.
