The product carbon footprint quantifies the greenhouse gas (GHG) emissions during the life cycle of a product,from raw materials extraction, through production, transportation, use and recycling, to the disposal of the used product.In this study, the carbon footprint of building ceramics produced in eastern China has been estimated,following the life cycle assessment and the actual production.The calculation boundary includes raw materials extraction, raw materials transportatio and building ceramics production.The carbon footprint of building ceramics is 8.65 kg CO2 per square metres.The proportion of every process also has been identified.The manufacture accounts for 80.7 % of the carbon footprint.The proportion of carbon footprint in other processes is less than 20%.Some measures to reduce the carbon footprint have been suggested, including substituting coal with other fuel, establishing a gas pressure control system, applying low temperature quick fire technology,using microwave drying, etc.Last, the important of developing new ceramic raw materials is pointed.
