There are various global problems we find ourselves faced with and those problems necessitate a new kind of ethic, a global one. I will argue that while there are several ways of understanding it one is more adequate than others. That claim has implications for the kind of basis suitable for global ethic, namely that we need a political ethic, such as liberalism. I will also take up some general objections which this kind of global ethic is able to give good replies.
Key words: global ethic, foundation for global ethic, institutional approach.
