Obligations of a company
A company makes decisions that have positive NPV. No list will ever be completely exhaustive since obligations are not necessarily zero-sum.

How do you increase profits for the shareholders? Mostly by taking care of the customers. How do you win customers? One way is to portray your company as environmentally friendly. This, in turn, helps the (wo)mankind and the nation. Do you see how it all pretty much ties together?

Of course, for a given company, one thing may be more important than the other.
