Going Back to the Basic of Green Economy： Special Reference to Economic Interpretation and Policies

It is no doubt that promoting green economy is the only option for the sustainable development. This paper provides a fundamental framework for economic studies on designing green policies that have many links with green technologies and environmental ethics. It also proposes a new theory of “pollution abatement stages model” in order to interpret how to improve environmental quality in a more efficient and effective way. For an intuitive understanding, we use more graphs instead of complicated mathematical equations to demonstrate ideas and the new theory. Key Words: green technologies, environmental ethics, green policies, pollution abatement stages model
