Abstract
For better energy policy and consensus building, we try to establish a scientific method to keep the basis of judgment clearly visible. In many cases, objective scientific assessment is mixed up with subjective judgment unintentionally. Thus, the roles of scientific advisors and policy makers are confused Therefore, we propose a quantitative method, with which evidence-based scientific assessment and value-based political judgment are to be clearly separated. The effectiveness of the proposed method is examined by a trial study on prioritization of research and development themes in the energy technology areas of Japan.
