Editorial to the Special Theme Sustainability

Sustainability represents a commonly agreed global development goal. It aims at ensuring the quality of life on Earth for current and future generations. should thus become fundamental overarching concept efficient/high-quality design operation any product or service throughout its lifecycle—focusing all three pillars sustainability—social, environmental, economic. Among different socioeconomic sectors, dealing with impacts that construction sector has is fundamental, as it strongly contributes to many pressing issues need be addressed. Not only do we improve economic, social performance our built environment, but also better prepared new conditions are appearing cause challenges (e.g., climate change). The importance this approach more clear in light an increasing number man-made natural disasters occurring globally. Thus, developments changes environment situation require improvements technology processes involved projects. In context, concrete particularly interesting material, because great potential technical solutions meeting requirements, leading necessary reduction environmental same time improvement economic conditions, including safety reliability during emergency situations. However, considering huge volume production negative closely linked production, overall impact associated structures scale considerable. view above situation, utmost focus introduction technologies, advanced techniques efficient operation, maintenance, recycling structures. Concrete mixes, products, designed meet requirements sustainability—namely, minimize their increase positive society, economy. This could achieved by durability cycle, through (i) methods, (ii) mixtures, composite materials, reinforcement (iii) modernization technology, (iv) integrated approaches, (v) innovation repair, demolition, processes. requires involvement actors process, from material manufacturers, designers, builders users, conviction initiative achieve results terms sustainability requirements. special theme Structural journal: Structures collects selection contributions related aspects showing contribute achievement Sustainable Development Goals (SDGs) set United Nations 2015 action plan until 2030. content covers Life Cycle Assessment structures, carbon neutrality, use recycled other components, optimization bringing contribution research SDGs.
