Recently, there are growing interests on carbon emissions related in climate change which is worldwide emerging important issue. Some research works are now carrying out in order to reduce the carbon emis- sion in pulp and paper industries by the synthesis of precipitated calcium carbonate using the exhaust car- bon dioxide from combustion furnace or incinerator. However, for solving the original problems on car- bon emission, we need to consider the analysis of basic methodology on CO2 through the process efficiencies. There are two general tools for carbon emissions; one is the greenhouse gas inventory and the other is LCCO2 method which is applied to particular items of raw materials and utilities in unit process. In this study, the carbon emissions in wood-containing printing paper production line were calculated by using LCCO2 method. The general materials and utilities for paper production, such as fibrous materi- als, chemical additives, electric power, steam, and industrial water were analyzed. As the results, Na2SiO3 showed the highest loads in carbon emissions, and the total amount of carbon emissions was the highest in electricity. In the production line of printing paper using de-inked pulp and BTMP, as the mixing ratio of DIP was higher, the carbon emissions were decreased because of high use of electric pow- er in TMP process.
