Abstract

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 to be 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 at 1.246 Tg C, AFA -11.520 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 $-5,258Gg\;CO_2$ (removals), AFA showed an increase of $4,877Gg\;CO_2$ (emissions), and PA showed a decrease of $-2,189Gg\;CO_2$ (removals). When applying Korean statistics, SCA showed a decrease of $-4,569Gg\;CO_2$ (removals), AFA showed an increase of $5,573Gg\;CO_2$ (emissions), and PA showed a decrease of $-1,628Gg\;CO_2$, (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.

본 연구는 교토의정서 제 2차 공약기간(2013~2017년) 이후 교섭에 있어서 국가별 탄소배출 흡수 인벤토리에 유력하게 포함될 전망인 HWP 탄소축적 변화량 및 배출량을 평가하기 위하여 우리나라 HWP 생산 수입 수출량에 대한 FAO통계와 국내통계를 적용하여 비교 추정하였다. 그 결과, 2005년 현재 HWP 탄소축적 변화량은 FAO 통계 적용의 경우 축적변화 접근법(SCA)이 1.434 Tg C, 대기유출입 접근법(AFA)이 -1.330 Tg C, 생산 접근법(PA)이 0.597 Tg C, 국내통계 적용은 SCA가 1.246 Tg C, AFA가 -1.520 Tg C, PA가 0.444 Tg C로 추정되었다. HWP으로 부터의 $CO_2$ 배출량 흡수량은 FAO통계 적용의 경우 SCA가 $-5,258Gg\;CO_2$ (흡수), AFA가 $4,877Gg\;CO_2$ (배출), PA가 $-2,189Gg\;CO_2$ (흡수), 국내통계 적용은 SCA가 $-4,569Gg\;CO_2$ (흡수), AFA가 $5,573Gg\;CO_2$ (배출), PA가 $-1,628Gg\;CO_2$ (흡수)로 FAO통계 적용이 국내통계 적용보다 모든 방법별 HWP 탄소축적 변화량 및 배출량 추정에서 유리한 것으로 나타났다.
