Abstract

Harvested wood products (HWP) are known as products from the tree such as sawn wood, plywood, particle board, structural lumber, wooden interior material, wooden furniture, and paper products. Because carbon is locked up in the HWP until eventual end-use of HWP, HWP played a role as the carbon storage which has the effect of stabilizing the concentration of carbon dioxide in the atmosphere. For these reasons, the suggestion that it must admit the carbon storage effect of HWP has been constantly raised. In 2011, the 17th session of the Conference of the Parties (COP) to the United Nations Framework Convention on Climate Change (UNFCCC) which was held in Durban, South Africa, assigned "Production Approach" which targets only the HWP producted by using round wood of domestic forestry as a official method for carbon accounting. Therefore, it is necessary that each country has to determine the half-life of wood in order to correspond to the discussions and negotiations between countries in the future and to develop an inventory of product-specific domestic wood. In this study, some countries' examples of the methods and conditions for determining half-life of HWP were investigated, and it was tried to derive the factor and methodology to determine half-life span of domestic HWP appropriately.

수확된 목제품(Harvested Wood Products, HWP)이란 제재목, 합판, 파티클보드 또는 목구조재, 건축내장재, 가구, 종이제품 등과 같이 나무를 원료로 사용하여 가공한 제품을 말한다. HWP는 수명을 다하여 폐기될 때까지 산림에서 생장하면서 저장했던 탄소를 장기간 제품 내에 저장하고 있기 때문에 대기 중의 이산화탄소 농도를 안정화시키는 효과를 발휘한다. 이러한 이유로, 탄소계정 시 목제품의 탄소저장효과를 인정해야 한다는 의견들이 지속적으로 제기되어왔다. 2011년 11월 더반에서 열린 17차 기후변화협약 당사국총회(COP)에서는 자국산 목재 만을 대상으로 하는 생산접근법을 HWP의 탄소계정방법으로 결정하였다. 이에 본 연구는 향후 국가 간 논의 및 협상에 대응하고자 국산 HWP 탄소계정에 필요한 인자인 반감기를 결정하기 위하여, 외국의 반감기 결정사례를 조사하고 국산 HWP 반감기 결정을 위해 필요한 요소를 분석하였다.
