Abstract:
      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.
