Environmental problem like global warming is a problem with three dimensions of activity subject. Enterprise, Nation and UN as a global organization. In this paper, environmental management is divided to macro and micro. Macro environmental management including national and global environmental management has more difficulty in terms of scientific evidence and governance for making consensus. Then, three types of failure, i.e. the failure of market, the failure of government and the failure of UN are explained. An implication of this paper is that global and national environmental management would be improved with experience and knowledge of micro environmental management.
