摘　　要：为了解卷烟产品在生产过程中的碳排放情况,应用生命周期理论对某典型卷烟产品在卷烟原材料加工、卷烟制造、运输等阶段进行了碳排放清单分析。结果表明,生命周期内该卷烟的碳足迹为79.709 4kg CO_2/万支,其中卷烟原料和卷烟材料加工阶段碳排放量在生命周期中所占的比例最高,为90.25%,具有决定性影响;卷烟制造阶段的影响次之,占9.22%;运输阶段产生的影响可以忽略。烟叶生产、醋酸纤维丝束生产和卷烟制造是降低卷烟碳足迹的关键环节。In order to clarify carbon emission characteristics of cigarette products, life cycle assessment was adopted to analyze the carbon emission of cigarettes of a typical brand at different stages, including raw material processing, cigarette manufacturing, transportation stages, etc. The results showed that in a whole life cycle, the carbon footprint was 79.709 4 kg of CO2 per ten thousand cigarettes; the raw material processing stage accounted for 90.25% of the total emission, which indicated that stage had decisive impact on the carbon footprint of cigarette. Cigarette manufacturing stage was the next with a percentage of 9.22%. Carbon emission at transportation stage was negligible. Tobacco leaf production, cellulose acetate tow production and cigarette manufacturing are key stages for reducing the carbon footprint of cigarette.
