Carbon footprint is broadly defined as carbon dioxide (CO2.) emissions normalized per unit mass of a product or per unit of an activity. It is considered as an important environmental indicator for comparing various products or activities. Fired solid clay brick is a popular walling material in India. Manufacturing of fired clay bricks involves combustion of fossil fuels during the firing process and during other unit operations and activities. Due to combustion of fossil fuels, dissociation of mineral calcite in the soil during the firing of green bricks and combustion of diesel during transportation of raw materials, the greenhouse gas emissions are associated with the manufacturing of fired clay bricks. About 250 billion bricks are manufactured annually in India.
