The study examines the concept of Corporate Social Responsibility (CSR) that is, how companies manage the business processes to produce an overall positive impact on society. The study observed that since the emergence of CSR in Nigeria, CSR is still at the discretion of the companies as there is no national law in the area of CSR. The study also observed that none of the International Corporate Responsibility Instrument, such as, the Organization for Economic Cooperation and Development (OECD) Guidelines for Multinational Enterprises; United Nations (UN) Global Compact and the 1998 ILO Declaration on Fundamental Principles and Rights at Works has been domesticated in Nigeria. The paper concluded that Nigerian government should provide a legal framework within which companies can effectively meet their obligations.
