A new approach of tree soft set with MCDM technique for leadership in international climate policy: measuring renewable energy sources and policies

Green technological progress can be achieved by mitigation efforts of leadership in climate policy. Renewable energies need to develop technological innovations for more competitive advantages. This study proposed a decision-making methodology for evaluating renewable energy sources under leadership in international climate policy. This study used the multi-criteria decision-making methodology to deal with conflicting criteria in the decision-making problem. The evaluation is based on the distance from the average solution (EDAS) method, which ranks the alternatives. The criteria weights are computed by using the average method. The neutrosophic set deals with uncertainty and vague information in the evaluation process. The neutrosophic set is integrated with the MCDM methodology. This study uses the concept of TreeSoft Set to deal with the problem as a tree and solve it easily. 15 criteria and 10 alternatives were used in this study. An empirical application was conducted to show the effectiveness of the proposed methodology. © (2024), (Neutrosophic Sets and Systems). All rights reserved.
