This paper presents a model to determine an optimal timing for remanufacturing from the environmental perspective. Long-run environmental impact per distance travelled L(sr) is defined based on the replacement theory. In the case study, the Weibull distribution function of crankshaft's time to failure is obtained. The L(sr) is calculated by dividing the total environmental impact with the distance travelled by the crankshaft. The minimum value of L(sr) indicates the best long-run environmental benefit. When climate change is selected as an environmental impact indicator, the result shows that the minimum value of L(sr) is achieved when the crankshaft reaches 1.53 × 105 km.
