When you're buying a new gadget, chances are you're more concerned about its feature set than the way it has been manufactured. If you do want to bring a greener slant to your purchases, Greenpeace's Guide To Greener Electronics is a sensible place to start.
The Greenpeace rankings, which are updated every three months, consider a range of factors, including the use of toxic chemicals and the extent of takeback programs for unwanted equipment. In the most recent rankings, unveiled at CES last week, the best-rated companies are Nokia and Sony Ericsson, while Apple has improved its performance. Nintendo, on the other hand, doesn't do so well (and is notable for a "no comment" approach to many aspects of its environmental policy).
Do you consider environmental issues when buying tech? Tell us why (or why not) in the comments.
