摘要
为深入研究普洱有机绿茶的生命周期碳排放情况,了解普洱有机绿茶的生产工艺及碳排放强度,从普洱有机绿茶生命周期的各个阶段出发,以普洱有机绿茶的生命周期二氧化碳排放为研究对象,将普洱有机绿茶的生命周期划分为原料获得、制造、配送及销售、消费者使用及废弃处理五个阶段,对其进行碳足迹评估分析.结果表明:1 kg普洱有机绿茶的总碳足迹为7.68kg,其碳足迹含量主要以制造与使用阶段为主,其占比分别为45.57%、30.07%.由此建议,在有机茶制造和采用阶段使用更多的清洁能源等措施以减少碳足迹.
Abstract
In order to further study the life cycle carbon footprint of Pu'er organic green tea and understand the production process and carbon emission intensity of Pu'er organic green tea,this paper researched the life cycle carbon footprint of Pu'er organic green tea from each stage of the life cycle of Pu'er organic green tea.The life cycle of Pu'er organic green tea was divided into five stages:raw material acquisition,manufacturing,distribution and sales,consumer use and waste treatment.The results showed that the total carbon footprint of 1 kg Pu'er organic green tea was 7.68 kg,and its carbon footprint content was mainly in the manufacturing and use stages,accounting for 45.57%and 30.07%,respectively.Therefore,it is recommended to use more clean energy and other measures in the production and use of organic tea to reduce the carbon footprint.
