Abstract
Sustainability or sustainable development has become commonplace in the economic literature and become increasingly relevant to the academic literature and widely discussed by numerous of the researchers into social and environmental responsibility or corporate social responsibility (CSR), both from an economic and moral perspective. However, the thorough discussion of CSR under business ethics perspective in a broad view from the international or global context, to the organisational responses, and to individual attitudes does not exist in the current literature. This paper attempts to discover ethical responses to CSR from international organisations, companies, and individuals. Especially, each response is explained by different ethical theory.
