摘　　要：以在我国造纸工业最具代表性的一家制浆造纸联合工厂为研究对象,采用“造纸和纸制品生产企业温室气体排放核算方法与报告指南”和温室气体核算体系计算工具的方法,研究了温室气体种类、核算边界和方法、工厂能耗和碳排放总量以及碳强度。结果表明,2014年该工厂碳排放总量为430496.772tCO2,不包含生物质能源产生的碳排放;基于工厂的纸浆碳强度为0.228tCO2/t风干浆,为基于产品获得的各种纸浆碳强度的7.4%~56.9%;基于国民生产总值(GDP)的碳强度为1.08tCO2e/1000USD,为我国造纸工业平均水平的56.3%;基于销售额的碳强度为0.301tCO2e/1000USD,约为国际纸业公司的52.6%。结果也表明,影响企业碳强度的主要因素有原材料种类、能源结构、产品结构等,以及为在碳排放交易市场中获得更多的碳排放交易权空间,企业应进一步进行节能减排。In this paper,the types of greenhouse gases,calculation boundaries and methods,energy consumption,carbon emissions and intensity of a typical integrated pulp and paper mill in China were studied based on the Accounting Method and Report Guidance for GHG Emissions from Pulp and Paper Industry and the Greenhouse Gas Protocol Tools.The results showed that there were 430496.772 t CO2 emissions from that mill in 2014 that did not cover CO2 emissions from biomass energy,which was 8 times higher than that of fossil energy.The carbon intensity based on the pulp was 0.228 t CO2/adt,which accounted for 7.4%~56.9% in other pulps' based on the product.The carbon intensity based on Gross Domestic Product (GDP) was 1.08 t CO2 e/1000 USD and accounted for 56.3% intensity in the China paper industry.The carbon intensity based on sales was about 52.6% of that of International Paper.It also showed that carbon intensity was influenced by the species of raw material,structures of energy and products,which provided the mill with measures for energy saving and CO2 emissions reduction to obtain the redundant carbon emissions in the trading.
