Together with the Authentic Natural Stone Network (PNA), Bagnara commissioned a study from the Polytechnic University of Turin with the aim of quantifying the environmental impacts of 1 m2 of slab with a thickness of 2 cm. For this purpose, the Life Cycle Assessment (LCA) methodology was used, based on the ISO14040-44 standard and the guidelines of the European Commission.
The project involved several companies in the PNA network, and 12 materials extracted and processed in Italy were examined. Different lithotypes from various geographical areas in central and northern Italy were studied, providing data on the entire production cycle of the slabs.
The study results demonstrate that the impact on climate change of a natural stone slab with a thickness of 2 cm has an average value of 7.9 kg CO2 eq/m2, which is much lower than the range of 15.5 to 29.9 kg CO2/m2 found for ceramic tiles.
