High Carbon Dioxide

Carbon footprint is defined as the amount of greenhouse gases generated during the whole lifetime or within a specific boundary of a product. This study measured the average carbon footprint of some common cotton knitwear T-shirts, polo shirts, and fleece jackets during production using CCalC2 software. Energy and water consumption data were taken as the study's input, while direct and indirect emissions were not specified. The results show the amount of carbon dioxide emitted at different stages of knitwear production. Cotton processing and yarn spinning resulted in relatively high carbon dioxide emissions, while wet treatment gave similar results. Fleece jacket production gave high amounts of emitted carbon dioxide due to its complex fabric structure and high fabric weight, while T-shirts gave the lowest amount of the fabrics tested.

Reducing Co2 Emission

Input-output model on cement plants were established. Carbon dioxide emissions of key steps and carbon footprint of products were calculated and predicted using the input-output model. The results showed that CO2 emission in the plant (the production of the plant is 1320000t a year) reached 910000 t a year and CO2 emission per ton product is 0.689 ton. Over 80% of the total CO2 was emitted during the process of firing，so the firing process is the key step for reducing CO2 emission in the cement plant. Carbon footprint of three kinds of cement products including ordinary portland cement, portland pozzolan cement and portland blast furnace slag cement are 0.76, 0.59, 0.72 respectively.
