AbstractThis study investigates the potential of cellular concrete as an environmentally friendly alternative for shear walls based structural systems in seismic‐prone areas. The construction industry significantly contributes to global energy consumption and carbon emissions, mainly through the use of conventional materials like concrete and steel. In seismic regions, the challenge is to build structures that are both sustainable and earthquake resistant. Through a “cradle‐to‐gate” life cycle assessment (LCA), the study analyses the environmental impact of constructing a seven‐story archetype residential building in Quito‐Ecuador. The research reveals that steel reinforcement is the primary source of CO2 emissions and energy consumption. Cellular concrete demonstrates a notable reduction in CO2 emissions compared with traditional concrete, emphasizing the potential of cellular concrete as a low‐carbon alternative. The findings underscore the need to integrate LCA into structural design to minimize ecological impact. While promising for developing cities, further research is essential to inform sustainable construction practices without compromising safety in seismic zones.
