Companies voluntary embody social and environmental actions via Corporate Social Responsibility (CSR). In this paper we indicate CSR polic ies in banking sector in Greece and we study the banks customers’ perceptions regarding their banks’ CSR polic ies. We present the ten biggest banks in Greece and we indicate the charitable programs and sponsoring that they offer in general during the last years in Greece. The present study empirically investigates the customers’ perception regarding CSR policies of banks; we study if they have really understood the meaning of CSR. Specifically, it is estimated whether customers believe that banks really wish to help society and the environment or they just wish to improve their sales and increase their profits. Under this framework, the results of empirical research are presented and the relevant findings are discussed.
