Environment in Industrial Ecology, Grasping a Complex Notion for Enhancing Industrial Synergies at Territorial Scales

Identifying the most relevant environment related indicators and how to make them available to decision-makers are current issues. Some seek to enhance their efficiency by means of methods such as aggregations or weighting. More fundamentally, in this chapter we question how industrial ecologists appropriate the notion of environment. On the basis of multidisciplinary research, we argue that, in contexts of geographically bounded networks of social actors forging industrial synergies, environmental questions should be posed from the viewpoint of the actors. Our work might aid to operationalize the complex notion of environment in such contexts, and constitutes a call to develop anthropocentric approaches to defining environmental indications followed by appropriated indicators.
