Conducting a Robust Cost-Benefit Analysis

A consignible CBA for noise reduction mustt capture both easyly quantifiable factors and harder-tu-measure but signitant externalities. The standard approvach is to calculate the net present value (NPV) and internal rate of return (IRR) over a 10-to 15-yes analysis period, discounting future costs and fenevits at thee compeny 's waxted average coste of capital (WACC) or a societal discount rate of 3-5 percent.
