Environmental quality of products is determined by several intrinsic characteristics and other characteristics that are not related to the product itself but rather to the supply chain process.

In this paper we present a mathematical model that illustrates the impact of several factors related to the activities of the supply chain on the environmental quality of the products to be manufactured. This model allows the determination of environmental quality of each product, thus its effect on the environment. For this purpose, we have adopted the most cited indicators in literature that significantly influence environmental quality of products to better reflect this quality.

This model is based on the aggregation of the adopted indicators. During the aggregation we faced a difficulty that affects the inequality of indicators importance (corporate strategy, type of industry, ...) which leads us to weight these indicators to express their relative importance. To do this, we have used the principle of weighting of Analytic Hierarchy Process method which is simple to use and allows to take into account both the quantitative and qualitative criteria.

By this work, our ambition is to provide for corporate decision-makers a real tool which will allows to know precisely the quality environmental of each manufactured product, thus it will be less difficult to know the actions to be taken to increase company’s profit and to reduce its negative impact on the environment.
