Abstract

This study estimated the amount of carbon stocks in harvested wood products (HWP) using accounting approaches suggested by 2006 IPCC guidelines and analyzed the impacts of different approaches on national greenhouse gas inventory and the forest sector in Korea. The change in carbon stocks was calculated at the level of semi-finished wood products, which cover sawnwood, wood-based panels, other industrial wood, paper and paperboard. An estimation of the changes in carbon stocks in HWP in use for the period 1970~2008 varied between -9,023 Gg $CO_2$/yr and 4,052 Gg $CO_2$/yr depending on the accounting approach used. The stock-change approach provided the most favorable results because Korea was a net importer of wood products. However, each approach generates different impacts on harvest, trade, the use of wood for energy production and recycling. When deciding its position on accounting approach, thus, the Government should consider future direction of national forest policies as well as the effect on national greenhouse gas inventory for the minimization of negative impacts resulting from its selection.

2006 IPCC 가이드라인에서 제안한 HWP 탄소계정 방법을 이용하여 HWP 내 탄소 저장량을 추정하였고 우리나라 국가 온실가스 인벤토리와 산림 부문에 미칠 영향을 분석하였다. 사용 중에 있는 제재목, 목질보드류, 기타 산업용 목재, 종이 및 판지를 대상으로 하여 목제품 내 탄소저장량의 변화량을 추정하였다. 1970년부터 2008년 동안 사용 중에 있는 목제품 내 이산화탄소 저장량의 연간 변화량은 접근법에 따라 -9,023 Gg $CO_2$/yr에서 4,052 Gg $CO_2$/yr으로 추정되었다. 우리나라는 목제품의 순수입국이기 때문에 탄소 축적 변화 접근법이 가장 유리한 결과를 보였다. 그러나 각 접근법이 목제품의 벌채량 및 교역량, 바이오에너지로의 목재 이용과 재활용에 미치 는 영향은 상이하게 나타나고 있다. 따라서 계정 방법에 대한 우리나라 입장을 결정할 때 국가 온실가스 인벤토리에 대한 영향뿐 아니라 미래에 추진할 산림정책 방향도 고려하여 야기될 수 있는 부정적인 영향을 최소화하는 방법을 선택해야 한다.
