the railroad has become a fundamental pillar of decarbonization of the European economy by 2050,” indicates Antonio Muñoz Garrido, Director of the Specialized Railway and Tunnels Unit, and Director of North Atlantic Construction in the ACCIONA Construction business. To achieve this vital climatic neutrality, the continental transpor-tation footprint must plummet some 90%. Another long road with stations like the European Year of the Railroad destined to drive its alternative. Why 2021? It is the first full year that the Fourth Railway Package will be rolled out, to eliminate institutional, legal and tech-nical obstacles and to promote railway services in the Union. RENEWABLE SUPPLY “The railroad is the axis of sustainable mobility. Low consumption on route and manufacturing [which tends to use ever more recycled materials] or nearly zero emissions are some of its environment- POSITIVE IMPACT OF INFRASTRUCTURE made in acciona HS Viaduct between Soria and Arcos del Jalon. The European Union wants to double High Speed traffic by 2030. POSITIVE IMPACT OF INFRASTRUCTURE made in acciona - The material conveyor belts during construction of the Qui-to Metro saved 1.7 million liters of diesel that trucks would have consumed. In the Follo Line (Norway) tunnels, 9,000 tons of CO2 have been avoided. - More than 90% of the material excavated in the Dubai Metro and the Follo Line tunnels was reused. - Other habitual practices: defining the tunnel section with la-ser to optimize consumption and reduce extracted material. The crushing and subsequent recovery of the waste. In Follo Line, the excavation consumes water that is treated and reused. - Padornelo Tunnel (Spain). Members of species like the Pyrenean Desman were relocated, which permitted a better understanding of their behavior to contribute to their conservation.
