The stabilized laterite brick contains a significant amount of cement (1:1.6:8.1 ratio of cement, sand and laterite) compared to the sancrete block (1:16 ratio of cement to sand). Thus, cement is a major contributor to embodied carbon emissions, and even a small quantity can influence the overall EC of a building.
