Sidenor 2022 Sustainability Report

61 490 KgCO 2 eq / t product Sidenor stands up for a quantitative and objective environmental evaluation of their products based on the Life Cycle Assessment methodology, and for the transparency in environmental communication through Environmental Product Declarations (EPD). Sidenor intends to use the EPD publication as a transparency tool for environmental communication. Since 2018, Sidenor performs Life Cycle Assessment (LCA) studies for all their products following the standards ISO 14040 and ISO 14044. During 2019 Sidenor aimed at elaborating and verifying the EPDs for their special steel quality products. In order to develop these EPD documents and their subsequent certification, an LCA study has been performed under the norm ISO 14025 and following the Product Category Rules "Basic iron or steel products & special steels, except construction products" from the International EPD® system. EPDs allow Sidenor to stablish a standardized environmental assessment procedure, in data collection stages as well as during the evaluation of the environmental impacts through an LCA study development. The carbon footprint (Potential of Global Warming or GWP) is an indicator that quantifies the contribution to the increase of the global average temperature derived from greenhouse gases emissions associated to the life cycle of a product. The calculation of this indicator has been performed with the method IPCC 2013. The result is expressed in kg of CO 2 equivalent for tonne of product.
