The use of wood for energy production could contribute significantly to increase the share of renewable energy in the European primary energy supply, help to meet the reduction of the Green House Gas emissions as well as create a significant number of jobs, especially in rural areas. However, for an extensive use of energy wood it is necessary to create a whole chain which includes collection, preparation, transportation and finally combustion of wood fuels. The aim of this paper is to present a Life Cycle Analysis (LCA) of energy wood chain, and in particular recovered wood. The computer model Global Emissions Model of Intergraded Systems (GEMIS) has been used as a calculation tool, while the methodology and the framework of the study have been based on ISO 14040. The LCA of this chain has shown that the benefit to the impact category of global warming is the most important result throughout the process of the wood utilization chain, while the most negative influence appears to the impact category of acidification.
