This chapter explores a few key concerns relating to sustainability. Ethics involves being able to understand what is right and what is wrong and being able and willing to select, and morally justify, courses of action accordingly. Business ethics is an applied form of ethics that addresses principles and problems that arise in doing business. Non-consequentialist ethics refers to eternal, universally applicable moral principles, objective qualities, and rational determination. An ethical product does not necessarily guarantee environmental sustainability. In the same way, an outwardly admirable practice of financial aid to developing countries does not lead to social sustainability. Good corporate governance codes, plans, and principles must also be fully integrated with corporate sustainability policies and practice, sustainability reporting initiatives, and broader corporate social responsibility commitments. Sustainability assessment tools such as life-cycle assessment and comprehensive management systems test environmental performance as well as employee welfare and health and safety.
