Abstract: The Brazilian ceramic industry is responsible for providing more than 90% of the roof coverings and wall bricks in the country, producing more than 15 billion pieces per year. Aiming to compare the life cycle impacts of ceramic versus concrete roofing tiles and identify potential improvements in ceramic products, the Brazilian National Ceramics Industry Association commissioned a life cycle impact assessment of these products. This study aims to compare the life cycle impacts of ceramic and concrete roof coverage over 1m2, with an assumed life time of 20 years in Brazil. Nine different sensitivity analyses were carried out followed by a Monte Carlo uncertainty analysis to verify the robustness of the study. The results show that ceramic tiles appear to have less impact than concrete tiles on Climate Change, Resource Depletion and Water Withdrawal, while for the remaining damage categories, Human Health and Ecosystem Quality, the difference between the two alternatives was too low to be considered significant. The use of wood chips led to significant impacts, mainly related to respiratory inorganics. Assessment of the data quality identified that the data is of generally high or acceptable quality. The sensitivity analysis and uncertainty assessment showed that the conclusions are robust.
