If you've let your subscription to Corporate Social Responsibility Magazine lapse, you may have missed their new list of "Best Corporate Citizens 2010." Hewlett-Packard, Intel, General Mills, and IBM top the list.I'm not sure about the integrity of this list, but you can find out more about the methodology they use here and see a big version of the chart above here.One problem is that this list doesn't make it easy to compare competitors. That means it's hard to incorporate into your buying habits. How's this: If you're trying to decide between buying 13 boxes of Lucky Charms or a pair of jeans from the Gap, go for the cereal.
