@ Parmnparsley- Don't quote me on this, but I believe they are both. Business ethics and corporate social responsibility are both related to the ethical behavior a business prides itself in. Where the two differ is the focus of the two. Business ethics are most often related to the economic functions of a business whereas corporate social responsibilities are the environmental and social responsibilities a business imposes on itself. When you combine the two, you have sustainable business ethics with varying degrees of sustainability based on the moral bounds of the organization. I hope this makes sense.
