Modern ski resorts have been using systems of technical snow for many years: initially they were used to compensate the limits of natural snow but today it is actually the natural snow that is used as an integration to artificial snow and not vice versa. This paper aims to identify and evaluate the environmental impacts associated to the production of artificial snow, comparing two very different winter seasons in terms of snowfalls. The results of LCA analysis shows that the production of artificial snow primarily implies impacts on natural land transformation and fossil depletion, and that more snowfalls cause more onerous skiing resorts management, due to high consumption of diesel fuel for piste machines used for snow grooming.
