Environmental group Greenpeace has issued the first quarterly update on the technology industry's performance on environmental issues.
The group recognised the contributions of a number of companies - including Nokia, Motorola, Fujitsu Siemens and Acer - but heavily criticised others, with some harsh words for last-placed Apple.
"Despite being a leader in innovation and design, Apple has made absolutely no improvements to its policies or practices since the ranking was first released three months ago," said Rick Hind, Legislative Director of Greenpeace USA's Toxics campaign. "Apple's bad green policy is not a wonderful life for workers in the scrap yards of the developing world, and we can't imagine that Steve Jobs would want to be the Mr Potter of the high-tech industry this holiday season."
The report ranks the 14 top manufacturers of personal computers and cell phones. Most companies, according to Greenpeace, now score above average points on the ranking guide, with only five companies failing to score even the average of five points. No company has yet to receive better than a 7 out of 10 rating.
Nokia continues to hold the top spot in the ranking for both its chemicals policy as well as disposal of electronic waste. Competitor Motorola, which was ranked second worst in the original September report, is seen as the fastest mover taking over the fourth spot in the latest report.
Fujitsu-Siemens and Acer made substantial progress and are now ranked 3rd and 7th respectively, moving up from their earlier 10th and 12th positions.
LGE, Samsung and Sony have lost points for failing to act on their commitments to individual producer responsibility. HP was given a "penalty" - one point was deducted from the company's overall score for using a product the company claimed was no longer being used.
Representatives from Apple were not immediately available for comment.
