The article reviews the recent research contributions and future promising perspectives regarding innovation in concrete technologies for low-carbon applications in buildings. To this aim, an original classification of recent trends is presented for reducing the carbon footprint of concrete constructions by identifying three main research lines. The first one is related to the enhancement of physical and mechanical properties of concrete, the second one is related to resource efficiency and raw materials’ saving and the third one concerns the role of smart concretes in building energy efficiency. Possible synergies between the three addressed main research lines are finally discussed.
