Benefit-Cost Analysis Is Very Well Suited to the Analysis of Projects

Benefit-cost analysis is very well suited to the analysis of projects with potentially large long-run impacts on the environment.
Because of the potentially large impact on future generations,it is difficult to determine the appropriate discount rate for benefit-cost analysis so instead,we may wish to avoid projects that reduce the long-run productive capabilities of our natural and environmental resource base,as well as avoiding making decisions that are irreversible,or that preclude taking other options in the future.
