title: [Modeling of carbon dioxide measurement and optimization on building ceramic industry].
abstract: Input-output model and low carbon programming model on building ceramic industry were established. Carbon dioxide emissions of key steps and carbon footprint of products were calculated and predicted using the input-output model. While products planning was optimized using the low carbon programming model. The results showed that CO2 emission in the enterprise reached 182 543.9 t a year and CO2 emission per unit product was 10% more than advanced level in the world. 80% of the total CO2 was emitted during the processes of firing and drying. As a result, we should focus on these two steps in order to reduce carbon dioxide emission of building ceramic industry. Carbon footprint of blank tile, polished tile, and glazed tile were 150.2 t, 168.0 t, 159.6 t respectively. Optimized by the low carbon model, The ceramic enterprise could reduce carbon dioxide emission by 5.4% while not sacrificing any profit, and also could obtain profit 5.6% higher than before while unrise the carbon dioxide emission.
