This site has much broader metrics than just carbon footprint.<p>I don't see any indication that the carbon release from their major manufacturing <i>subcontractors</i> (e.g. Foxconn) is included.
Cool to see this type of overall analysis for Apple. I've seen several different attempts at this type of quantification in terms of sustainability/impact/whatever it's called. This eval looks user friendly and has the categories I would expect.
