Answer:
Sustainability is how long a business can last or strive in the market while going about their responsibilities. Corporate social responsibility is doing business in ways that are beneficial and not harmful to the society or environment.
An organization cannot be good at both if they cannot balance their responsibilities toward their workers, society or government.
A company can be involved in the production of good products at low cost and yet they are involved in wasting natural resources and emission of carbon. Such a company is not environmental friendly and is not socially responsible.
CSR and sustainability go together these days. The relationship here is that if a company is able to benefit the society and environment, then it would be able to get increased output, a positive image and quite a good number of customer base would want to patronize them for being socially responsible.
The difference between them is that CSR takes the welfare of all parties into consideration, the society and environment inclusive. While sustainability does not consider all factors.
