摘　　要：基于生命周期分析(LCA)法对比考察中国造纸行业在林木生产、工厂生产、运输、废弃物处理各阶段的CO_(2)排放量。研究发现,2009—2021年中国使用废纸造纸造成的碳排将小于采用原木纤维进行生产造成的碳排量,即增大国内废纸回收将有助于中国降低CO_(2)排放量。其中,约69%的碳减排效应均来自运输阶段,20%源于工厂生产阶段。通过分品类对比发现,箱纸板、瓦楞原纸和未涂布印刷书写纸的碳减排效应最为明显,2021年分别减少54758、51006、30720万t CO_(2)排放量。Based on the LCA life cycle analysis method,the CO_(2) emissions of Chinese paper industry in stages of forest tree production,factory production,transportation and waste treatment is compared.It is found that the carbon emissions caused by using waste paper in China from 2009 to 2021 is less than that caused by using log fiber production.That is,increasing domestic waste paper recycling can help reduce CO_(2) emissions in China.About 69%of these reductions come from the transport phase and 20%from the factory production phase.By category comparison,it is found that the carbon emission reduction effect of box board,corrugated base paper and uncoated writing paper is the most obvious,which could reduce the CO_(2) emission of 54758,51006 and 30720 million tons respectively in 2021.
