How to subtract two sets of data for a ListPlot

Hi all.  Suppose I've calculated two sets of lists of the form for example:

list1={{1,1},{2,2},{3,3}};

list2={{1,1},{2,4},{3,9}};

What's an efficient way to create a third list with the same x-values but with the y-values subtracted

newlist={{1,0},{2,-2},{3,-6}};

I realize I can manually subtract them in a For-loop, but I'm sure a one-line command using Map or some other construct can be used as well but can't figure it out.

Thanks!
