Environmental Cost Indicator (ECI/MKI)

The Environmental Cost Indicator (ECI, or in Dutch: Milieukosten indicator) is a single-score indicator expressed in Euro. It unites the LCA results of all impact categories into a single score of environmental costs, representing the environmental externalities of a product or project. It is based on EN15804+A2, and used in the Dutch construction industry to determine the winning bids in public tenders.
