In its commercial offer to the Urban Community of Marseille Provence Métropole, the Marseille waterworks (Société Eaux de Marseille – SEM) committed to assess the environmental footprint of its activities as part of its contract. The scope includes the urban water cycle (from the production of drinking water to the treatment of waste water).
2EI measured the environmental footprint of SEM’s activities, through 4 indicators describing the four main environmental issues that are climate change, the preservation of water resources, the preservation of ecosystem quality and the preservation of resources in general: Carbon Footprint, Water Footprint, Biodiversity Footprint, Resources Footprint. These indicators are based on standardised ISO methodologies, and in particular life cycle analyses.
On top of observing its contract commitments, SEM has extra-financial indicators enabling it to compare and/or favour new solutions, according to the sustainable development approach.
