我国日用玻璃行业碳排放特征及减排措施

玻璃行业是我国能源消耗和碳排放量较大的行业之一，为分析占玻璃行业30%以上产量的日用玻璃行业的碳排放特征，本文基于排放系数法对2015—2020年行业碳排放量进行了核算，在此基础上，提出了相应的碳减排措施. 结果表明:我国日用玻璃行业碳排放量由2015年的2 617.04×104 t逐步降至2020年的2 149.95×104 t，且随着行业技术进步、清洁燃料的推广使用，单位产品碳排放量不断下降；从排放构成看，行业碳排放主要包括化石燃料燃烧产生的直接排放和外购电力及热力产生的间接排放，其排放量占排放总量的88.75%~92.27%，原料碳酸盐分解产生的过程排放相对较少，占比为7.73%~11.25%. 研究显示，降低日用玻璃生产过程中的能源消耗是减少碳排放的重要方向，调整能源结构、提高能源利用效率和优化原料结构是减少碳排放的主要措施. 

Carbon Emission Characteristics and Emission Reduction Measures of Domestic Glass Industry in China

Glass industry is one of the industries with high energy consumption and carbon emission in China. This study mainly analyzed the carbon emission characteristics of the domestic glass industry, which accounts for more than 30% of the output of the glass industry, and calculated the carbon emissions from 2015 to 2020 using the emission coefficient method. On this basis, the corresponding carbon emission reduction measures were proposed. The results show that the total emissions decreased from 2617.04×104 t in 2015 to 2149.95×104 t in 2020, and with the technological progress and the promotion of clean fuels, the carbon emissions per unit product decreased continuously. The carbon emissions from the domestic glass industry are mainly generated from fossil fuel combustion and electricity purchase, accounting for 88.75%-92.27% of the total emissions. The decomposition process of raw material carbonate is relatively small, accounting for 7.73%-11.25%. The assessment results indicate that reducing energy consumption in domestic glass production is an important direction to reduce carbon emissions. Adjusting energy structure, improving energy utilization efficiency, and optimizing raw material structure are the main measures to reduce carbon emissions.
