Life cycle analysis (LCA) is a systematic and analytical methodology that allows you to evaluate the environmental impact of a product or service during its entire life cycle, starting from the extraction of raw materials until final disposal. The main objective of LCA is to understand and evaluate the environmental impact generated by a product or service in the different phases of its life cycle, through an objective and technically reasoned evaluation. At the end of the calculations, the environmental footprint is returned through different "impact categories", which represent all the environmental impacts generated in the various environmental sectors. The LCA study helps to understand the impact generated on the environment by products, services, economic systems and production chains and constitutes a technical basis for a wide range of actions aimed at increasing the sustainability of products and supply chains . Once the "system boundaries" have been defined (i.e. the field of analysis), the LCA study allows the environmental impact generated by the various production processes included in it to be measured, identifying those with the greatest impact and thus understanding the environmental performance of each production cycle objectively. The ultimate aim of the LCA is to be able to manage the calculated environmental impacts, through their reduction and compensation.
