Low carbon efficiency indicators and decision model of rare earths industry from the stakeholders'perspective

The stakeholders and the pattern of interests on the basis of introducing rare earth industry operation mode were analyzed. Based on the established low carbon efficiency indicators in China and beyond, the indicators were designed from the aspects of input, output, emissions, and regulation following the WBCSD eco-efficiency evaluation criterions and the low carbonization characteristic of rare earths industry. The efficiency of low-carbon industry was evaluated by using Hesitant Fuzzy Multiple Attribute Decision Making Method based on group consistency and gray correlation analysis. The results show that, among the four interest groups, the satisfaction degree of the local government is ranked the highest, next comes the rare earth enterprises, consumers the third, the central government the lowest. This decision model has the advantages of quick calculation, high reliability, and objective results.
