SUSTAINABLE ECOSYSTEM VIA ECO-EFFICIENCY ASSESSMENT IN CAR MANUFACTURE COMPANY

In this research we have calculated co-efficiency by dividing the cost of net sales of products to environmental impacts of products. This evaluation has been considered only by automotive industries. For knowing the excellence of economic and environmental state in factory, co-efficiency evaluation, couples these factors together. In this paper co-efficiency of automotive industries have been measured quantitatively and have been shown that these factors have been increased gradually in the period of 4 recent years. By comparing co-efficiency in recent years ,it is evident that co-efficiency has been increased with gradual growth rate . It means that production process done with less resources use and less waste generation. Comparison of four recent years of eco-efficiency shows that, automotive industries in Iran are co-efficient in all aspects. It is recommended that this evaluation being done in other industries.
