摘　　要：基于生命周期评价理论与国家温室气体清单指南中废弃物处理温室气体排放计算方法,对中国2010年和2015年纸产品生命周期不同阶段的主要温室气体排放分别进行了分析.研究的纸产品生命周期评价边界包括:林木种植管理、制浆造纸过程、运输过程、废纸回收制浆、焚烧和填埋.结果表明:中国2010年和2015年纸产品生命周期温室气体排放量分别为13.4、20.3 Mt CO2-eq,其中林木种植和管理阶段为碳汇,能存储的CO2分别为82.6和108.2 Mt CO2-eq,制浆和造纸阶段为碳源,排放的GHG2分别为52.4、77.3 Mt CO2-eq,运输阶段为8.3、10.3 Mt CO2-eq,废纸焚烧和填埋阶段为35.3、40.9 Mt CO2-eq.Applying life cycle assessment methodology coupled with calculating methodology of greenhouse gas （GHG） emissions of waste management in Guideline for national Greenhouse Gas Inventory, the life-cycle GHG emissions from paper product in China based on the data in 2010 and 12nd developing plan of paper product were calculated. The life cycle boundary included forest planting and management, pulp and paper-making, transportation, waste paper to de-inked pulp, incineration, and landfill. Results show that the total GHG emissions of paper product in 2010 and 2015 are 13.4 and 20.3 Mt CO2-eq, respectively, in which GHG are stored at forest planting and management are 82.6 and 108.2 Mt CO2-eq, respectively, the GHG emissions from pulp and paper-making are 52.4 and 77.3 Mt CO2-eq, respectively, the GHG emissions from transportation are 8.3 and 10.3 Mt CO2-eq, respectively, and the GHG emissions from waste paper to incineration and landfill are 35.3 and 40.9 Mt CO2-eq, respectively.
