Greenpeace posted the latest edition of its "Guide to Greener Electronics" yesterday, which ranks the top 18 consumer electronics companies by their policies towards toxic chemicals and recycling, and it looks like the rankings have shifted slightly since last time -- Sony Ericsson and Samsung have tied for the lead with a 7.7 out of 10 rating (taking over from Nokia, which fell to number 9 with a 6.7) and Sony is sitting pretty at number 3 with a 7.2. Apple, which has taken some lumps in the past few months, is right in the middle of the pack with a 6, but most surprising is Nintendo, which came in absolutely dead last with a big ol' 0 -- looks like Mario wasted a little too much water in Sunshine, eh?
