With the very large scale category (4) matters there is the teaching issues question of whether business ethics should be concerning itself with 'macro' issues about the ethicality of whole economic systems and, in particular, concern itself with the justice of the capitalist system.

In relation to international business there is a whole range of questions to do with globalisation and the operations of multinational companies (particularly in the developing world) as well as questions of special interest to business ethics to do with 'ethical relativism': the notion that ethics has no sort of objective basis but is simply a question of the attitudes and beliefs of particular cultural groupings. While with environmental problems, we have what is a whole area of study in itself to do with how businesses should respond to them and whether their solution lies with regulation or market mechanisms as well as the development of whole new ways of thinking about moral matters in the shape of 'environmental ethics' based on notions of 'animal rights', or respect for all living things (animals and plants), or even whole eco-systems (land, air, and water as well as living things).
