Fujitsu's approach for eco-efficiency factor

Eco-efficiency is one of the many indicators for measuring damage to the environment. The Eco-efficiency Factor is a quantitative indicator that enables us to evaluate changes in service performance and the environmental burdens that are imposed. This paper presents a case study of two notebook personal computers manufactured eight years apart. To evaluate service value, core hardware specifications such as CPU clock speed, memory size, and hard disk drive size were compared. The results show that the more recent notebook has about 24.6 times the service value of the older one. The results of inventory analysis from EcoLeaf, which is a Japanese Type III labeling program based on Life Cycle Assessment (LCA), are used as environmental burdens. Then, we used LIME (Life cycle Impact assessment Method based on Endpoint modeling) to integrate the inventory data of EcoLeaf. The integrated result showed that environmental burdens have dropped about 22%. It is concluded that the Eco-efficiency Factor has increased about 32 times in 8 years. Due to the usefulness of the Eco-Efficiency Factor, it could become an important communication tool between manufactures and green consumers in the near future.
