摘要
This paper proposes the environmental burden and benefit assessment method, which contributes to the evaluation of public works, by considering a quantitative environmental impact. The method developed is applied for the Bangkok subway construction project, so that the environmental impact following the Bangkok subway construction work is evaluated on the basis of environmental accounting. As a result, it was possible to quantify the burden and benefits to the environment in the life cycle of the Bangkok subway. In addition by converting the burden and benefits of the Bangkok subway construction project into monetary terms and introducing the Economic Internal Rate of Return （EIRR）, it was possible to evaluate the subway construction project from an economic point of view.
