Development and testing of the Product Environmental Footprint Milk Tool: A comprehensive LCA tool for dairy products.

The paper describes the general structure of the PMT_01 tool developed to assess the environmental impacts of different dairy products as Protected Designation of Origin (PDO) cheeses of Lombardy Region (Po Valley - Northern Italy) and High Quality fresh pasteurized milk in a cradle-to-distribution center gate approach. Based on the PEF Product Environmental Footprint (PEF) methodology, the authors aim to provide a useful instrument for technicians and researchers in the evaluation of the environmental load of dairy products, allowing the process-hotspots identification through 16 different impact categories. The tool requires a modest amount of data that can be easily collected at the farms and at the dairies.

Effect of farming strategies on environmental impact of intensive dairy farms in Italy.

Agriculture and animal husbandry are important contributors to global emissions of greenhouse (GHG) and acidifying gases. Moreover, they contribute to water pollution and to consumption of non-renewable natural resources such as land and energy. The Life Cycle Assessment (LCA) methodology allows evaluation of the environmental impact of a process from the production of inputs to the final product and to assess simultaneously several environmental impact categories among which GHG emissions, acidification, eutrophication, land use and energy use.
