Abstract
본 연구는 국가 온실가스 배출량 평가에서 향후 적용될 2006 IPCC 신규 가이드라인의 적용성을 검토하고자 해외사례를 분석하고, 기존 가이드라인과의 방법론 및 배출계수 차이점을 분석하여 실제 배출량을 산정해 보고자 수행하였다. 해외 ANNEX I 국가들의 적용성을 검토한 결과 우리나라와 농업여건이 비슷한 일본의 경우 일부는 2006 IPCC 가이드라인의 방법론과 배출계수를 적용하고 있었으며, 미국의 경우는 대부분이 2006 IPCC 가이드라인을 적용하여 배출량을 산정하였다. 1996 IPCC와 2006 IPCC 가이드라인의 방법론과 기본계수를 적용하여 경종부문 온실가스 배출량을 평가한 결과, 신규가이드라인을 적용했을 때 약 26~29%의 배출량이 감소되었다. 이러한 배출량 차이에 대한 주요 원인은 일부 배출원 항목에 대한 삭제 및 배출계수의 차이에 있음을 알 수 있었다. This study was conducted to compare of greenhouse gas emissions between 1996 and 2006 IPCC (Intergovernmental Panel on Climate Change) guidelines change. Greenhouse gas emissions were calculated separately by rice cultivation, agricultural soils and field burning of agricultural residues from 2000 to 2008 according to 1996 and 2006 IPCC guidelines. To calculate greenhouse gas emissions, emission factor and activity data were used IPCC default value and the food, agricultural, forestry and fisheries statistical yearbook of MIFAFF (Ministry for Food, Agriculture, Forestry, and Fisheries). The greenhouse emissions by 1996 IPCC guidelines were highest in rice cultivation as 4,008 <TEX>$CO_2$</TEX>-eq Gg of 2000 and 3,558 <TEX>$CO_2$</TEX>-eq Gg of 2008. The emissions by N-fixing crops, crop residues returned soils and field burning did not much affect the total emissions. <TEX>$CO_2$</TEX> emissions by urea and lime were calculated by adding in 2006 IPCC guidelines and its emissions were 157 and 82 <TEX>$CO_2$</TEX>-eq Gg in 2008 respectively. The emissions by N-fixing crops, crop residues returned to soils and field burning, in common with 1996 IPCC guidelines, did not have a significant impact on total emissions. The total emissions in agronomic sector was decreased continuously from 2000 to 2008 and annual emissions by 2006 IPCC guidelines were approximately 26-29% less than the 1996 IPCC guidelines.
