Sustainability, Responsibility and Ethics: Different Concepts for a Single Path

The main goals of this paper are: (1) to analyse the concepts of sustainability, responsibility and ethics focusing on their links and differences, also to understand how companies move respectively in these field; (2) to understand how companies sometimes move away from the basic and deep meaning of these concepts, landing in a merely utilitarian sphere of personal advantage where ethics, instead of being an irreplaceable and essential stronghold, is found to be a fiction or just an instrument.\r\nThe methodology used assumes a theoretical critical approach and, based on the vast literature on the items, is based on a conceptual analysis of the themes of sustainability, corporate social responsibility and ethics and of the behaviour that companies can adopt in the three contexts. A critical approach to these issues and concepts can effectively help us to understand how companies are responding to external demands and to the challenges of responsibility and sustainability, which are becoming increasingly pressing.\r\nEthics, sustainability, CSR and SER are distinct constructs with different meanings but linked by important conceptual and operational relationships.\r\nThe results of the research are the consequence of the application of a critical approach based on a theoretical analysis of the concepts under study. It would be interesting to support the results achieved with empirical researches.\r\nThis conceptual path helps scholars and companies themselves to understand the difference between the three key concepts analyzed. Only by understanding the basic meaning will it be possible to really make one's own and pursue it in the correct way.\r\nNowadays we are overwhelmed by these three concepts which are used as synonyms and incorrectly. This leads to confusion and misunderstandings. Knowledge of the characteristics and differences between these concepts and their concrete applications is of great importance.\r\nThis work tries to provide a critical discussion of how the three concepts intersect and differentiate, leading to concrete results or results that have nothing to do with their meaning. There are no conceptual papers in the literature that deal with the three concepts and also analyze the implications on the real world.
