Corporations with sustainability programs see better employee morale, an improved public image and increased efficiency, according to a new survey from the Society for Human Resource Management.

In fact, 53 percent of respondents report that their sustainability initiatives led to better employee morale while 51 percent of respondents say those enhanced their public image. Forty-seven percent of respondents say they experienced more efficient business processes.

Another 37 percent of respondents say they measured the return on investment of their sustainability initiatives, and of those, 56 percent say they saw a positive ROI. Thirty-nine percent of those respondents say it is too early to tell, and 5 percent say they broke even. Only 1 percent of respondents say they experienced a negative ROI.
