The Changes in Carbon Stocks and Emissions Assessment of Harvested Wood Products in Korea

摘要

This study compared and estimated the changes in carbon stocks and emissions of harvested wood products (HWP) by applying FAO statistics and domestic statistics for Korean ,HWP production, import, and export volume, which is almost always supposed tobe included in the carbon emissions and removals inventory by country in negotiations since the 2nd commitment period (2013-2017) of the Kyoto Protocol, for assessing the changes in carbon stocks and emissions of HWP. As a result, when applying FAO statistics to the changes in carbon stocks of HWP as of 2005, stock-change approach (SCA) was estimated at 1.434 Tg C, atmospheric-flow approach (AFA) -1.330 Tg C, and production approach (PA) 0.597 Tg C. When applying Korean statistics, SCA was estimated at1.246 Tg C, AFA -1.520 Tg C, and PA 0.444 Tg C. When applying FAO statistics to CO_2 emissions and removals from HWP, SCA showed a decrease of -5,258 Gg CO_2 (removals), AFA showed an increase of 4,877 Gg CO_2 (emissions), and PA showed a decrease of -2,189 Gg CO_2 (removals). When applying Korean statistics, SCA showed a decrease of -4,569 Gg CO_2 (removals), AFA showed an increase of 5,573 Gg CO_2 (emissions), and PA showed a decrease of -1,628 Gg CO_2 (removals). Therefore, the application of FAO statistics was shown to be more beneficial for the estimation of both the changes in carbon stocks and emissions of HWP by all methods other than that of Korean statistics.
