In a very uncertain and competitive economy, companies have to cope with external constraints such as environmental and social issues, to gain competitive advantage. Over the last thirty years, numerous initiatives have appeared to deal with socio-environmental issues. However, contexts are complex and dynamics. Many authors therefore point out the need to establish a systemic perspective in order to improve the integration of sustainable issues into all company activities: from strategic decision-making to the end of the project. In addition, companies need to reinforce the relationship between general corporate development and eco-design activities. Based on literature review, this paper assumes that the integration of sustainability can be improved by developing a coherent and system approach between strategic, tactical and operational levels. The authors have chosen to demonstrate this assumption by targeting the environmental aspect of sustainability as a first step of their overall research. In this view, this paper proposes a navigation system composed of three modules: strategic, tactical and operational. This navigation system provides some pragmatic roadmaps for integrating environment into the company. Each module is linked to the others by the use of appropriate metrics. Bottom-up and top-down or middle-to-sides strategies are fully supported.To test this proposal, the navigation system is experimented retrospectively into an industrial process from the textile industry. The comparison between the initial situation and the experimental results allows authors to highlights potential environmental improvements. Some recommendations are made to challenges companies to use this navigation system, which argues in favor of environmental improvements.
