Greenpeace has released the fifth version of its Guide to Greener Electronics, and lauds the tech industry for making “great improvements” since the first scorecard hit the scene in August 2006. Nokia, Sony Ericsson, and Dell took the top three spots this time around; Apple, the CEO of which was rankled by his company’s dead-last ranking in April, is now solidly tied with Hewlett-Packard for second-to-last, ahead of Panasonic. The report, released yesterday, noted that HP is “in free fall” on the list; also yesterday, coincidentally, HP launched an effort to improve e-waste recycling in Africa.
