This paper describes the promotion measures to motivate agreement among stakeholders as below; 1. Indicating the further improvement of the cost-benefit ratio (B/C) to be shared among stakeholders in consideration of a variety of non-energy benefit (NEB) 2. Identifying B/C for each stakeholder in consideration of the revert of each cost and benefit belonging to some specific stakeholders 3. Expression of the risk caused by the uncertainty of cost and benefit estimation in the early planning phases of projects, and seeking proper allocation of cost and benefit, depending on the difference of the risk preference among stakeholders The effectiveness of the concept above is verified through a case study based on an actual project.
