The latest Greener Electronics Guide sees Nintendo become the first company to score 0/10 for its policies and practices on toxic chemicals and takeback.
Greenpeace ranks companies on two criteria - the clean up of products by eliminating hazardous substances and the takeback and recycling of products once they become obsolete.
Microsoft scored 2.7/10, with points for chemical management and for setting a timeline to phase out PVCs by 2011.
Sony scores much better than its rivals, with 7.3/10, although this covers the whole of the electronics company's products. With no mention of the PlayStation 3, it's noted that Sony produces many products that are free from PVC including the VAIO notebook, Walkman, camcorders and digital cameras. http://www.gamesindustry.biz/content_page.php?aid=31002
