Activist group Greenpeace has released a new edition of its Guide to Greener Electronics, which ranks major high-tech corporations in terms of their alleged environmental friendliness. Among the companies favored by Greenpeace's press efforts is Apple, which the group notes recently disclosed its carbon emissions. Apple has risen in rankings from 11th to 9th, aided not by the disclosure but by being the "most progressive" computer maker in terms of removing product toxins.
