Acciona Construcción has been the first private Company in the world to obtain an Environmental Product Declaration (EPD) for a civil works infrastructure, specifically for the railway viaduct performed in the High speed North-North-east corridor sub-section Otero de Bodas-Cernadilla (Zamora, Spain).
The EPD or type III eco-label is a certified environmental declaration in accordance with ISO 14025 issued by the International Organisation EPD®, that certifies the potential impact on the Environment of a product or activity throughout its life cycle based on the methodology of Life Cycle Analysis (ACV).
The data that is evaluated for the life cycle assessment are, mainly, materials used (type and quantity), energy consumption throughout the infrastructure construction process and waste generated, since it is necessary to consider all construction stages, from the extraction of raw materials to the end of the product life cycle.
The tools for the life cycle analysis are currently considered an objective methodology for the environmental impact assessment of products, processes and services, and are used in different countries, even promoted by Public Administrations as a means to assess the environmental impact of projects before their tender and during construction. The purpose of EPDs is to provide quantitative, transparent, verified and comparable information on the different environmental impacts that may be caused by a product throughout its life cycle.
They are therefore a useful tool for the compliance of current legislation and for the environmental improvement of the sector. They are verified by an independent third party and they also allow to provide information to the user of the supply chain and to the final consumer.
