The paper describes the environmental impact assessment of wood pellet and wood chips production through a Life Cycle Analysis carried out using a detailed LCA software (Simapro6.0). The Life Cycle Assessment (LCA) is a methodology of analysis finalized to appraise in the way most complete possible the environmental load of whichever activity. The life cycle of a product or a service is examined "from the cradle to the grave", through the compilation of an inventory of input (material, energy, natural resources) and output (issues in air, water, ground), the evaluation of potential, direct and indirect impacts., the analysis of the results and finally the definition of the possible lines of intervention to reduce its environmental impact. The maturity of the methodology is testified by the recent issue from the ISO (International Standards Organisation) of the relative normative technique (ISO14040-14044). Methodology is used therefore to compare among them different technologies for the production of energy from biomasses. The modern structure of the LCA is composed from four principal moments: a. Goal definition and Scoping: an inventory step which entails identifying and quantifying the resources used (including energy, raw materials, and capital) and wastes and emissions generated at each phase of production; b. Life Cycle Inventory (LCI): the first part of the job, devoted to the study of the life cycle of the process or activity. The principal purpose is to reconstruct the flow of the energy and of the materials; c. Life Cycle Impact Assessment (LCIA): the study of the environmental impact provoked by the process or activity, that has the purpose to underline the entity of the modifications produced following the consumptions of resources and the releases in the environment calculated in the inventory; d. Life Cycle Interpretation: the conclusive part of a LCA, that the purpose has to propose the necessary changes to reduce the environmental impact of the process or activity considered.

Abstract
The paper describes the environmental impact assessment of wood pellet and wood chips production through a Life Cycle Analysis carried out using a detailed LCA software (Simapro6.0). The Life Cycle Assessment (LCA) is a methodology of analysis finalized to appraise in the way most complete possible the environmental load of whichever activity. The life cycle of a product or a service is examined "from the cradle to the grave", through the compilation of an inventory of input (material, energy, natural resources) and output (issues in air, water, ground), the evaluation of potential, direct and indirect impacts., the analysis of the results and finally the definition of the possible lines of intervention to reduce its environmental impact. The maturity of the methodology is testified by the recent issue from the ISO (International Standards Organisation) of the relative normative technique (ISO14040-14044). Methodology is used therefore to compare among them different technologies for the production of energy from biomasses. The modern structure of the LCA is composed from four principal moments: a. Goal definition and Scoping: an inventory step which entails identifying and quantifying the resources used (including energy, raw materials, and capital) and wastes and emissions generated at each phase of production; b. Life Cycle Inventory (LCI): the first part of the job, devoted to the study of the life cycle of the process or activity. The principal purpose is to reconstruct the flow of the energy and of the materials; c.
