Applied within the context of a life cycle assessment (LCA), the ecological scarcity method allows for the assessment of the impacts generated by the releases of pollutantsand extraction of resources identified in a life cycle inventory analysis. Eco-factors, expressed as eco-points per unit of pollutant emission or resource extraction, are the key parameter used by the method. The publication sets out how the eco-factors are determined, reflecting, on the one hand, the current emission situation, and, on theother hand, Swiss national policy targets as well as international targets supported by Switzerland. New statutory and political settings, new findings and experience, and thechanging emission situation make it essential to adapt the eco-factors regularly. The present edition adjusts the eco-factor formula to the structure of the relevant ISO standard, updates the figures on which existing eco-factors are based, and takes account of new substances and resources.
