Lyfe Cycle Assessment – LCS and the phase of Environmental Impact Assessment
considerations on the use of diferente methods and their reflexes on final results
Abstract
Life Cycle Assessment represents a consistent tool and is in line with the principles of sustainability, with great potential to aid in making decisions regarding the most diverse areas and industrial and political sectors. Due to the wide range of applications to which it is addressed, and referred to its potential, the realization of LCA demands clear identification and documentation of the considerations made during the study, and the methods used to ensure the correct interpretation of the results provided. This research aims to highlight the differences resulting from the use of six methods of impact assessment applied to LCA of one ton of Portland cement CP III 32. The platform to support SimaPro 7.3 was used in order to assess to which extent the choice of a method may influence the results and the resulting interpretation of the study as a whole. The study showed that for all methods, the class of impact on climate change is highlighted, but the other classes of impact varied in terms of their importance before the environmental problem as a whole, may result in different conclusions about the environmental load characteristic of the product reviews. Moreover, he emphasized the importance of careful choice of method, and knowledge of the methodology adopted for each type of impact assessment.
