The increasing carbon foot print on the environment is a growing concern. The carbon foot prints of NXTBLOC AAC blocks are considerably less compared to traditional walling materials (per sq ft carbon levels: AAC blocks 2.13 kg of CO2, clay bricks 17.6 kg of CO2, concrete walls 14 kg of CO2). Aiding further, the light weight of NXTBLOC AAC blocks reduces the carbon emission as more cubic meter can be transported per truck load as compared to traditional walling material (3 trucks traditional material in cu m equates 1 truck AAC blocks in cu m).
