The enterprise coordinates social resources, which changes the dialogue between human and the environ-ment into that between enterprise and environment. The profit-making character of enterprise leads to the abandon-ment of environmental ethics. Enterprise, which has the capability to solve environmental problems, however, lacks-the motive to do it. It has controlling power over society and should assume the responsibility of environmental protection. For its lack of environmental conscience, the external institutional arrangements should be made for enterprise. The strategy for environmental cost should be designed in connection with the interest orientation of en-terprise. And various tegal measures in constitutional law, social law, civil law, administrative law and criminal law should be utilized to regulate enterprise's behaviors regarding environmental protection.
