The concept of 'green' in economics had emerged after 1950 and was introduced by Environmental Economists. Now a days, beside green economics, ecological economics or environmental economics researchers are also focusing on green business process management, green marketing, green accounting, green financing, green supply chain management, green HRM. Based on the semantic similarities it is easy to guess that all these green business concepts are rooted in Environmental Economics or in any of its branches, but is there any article or any related publication which can be used as reference for claiming this true?
