Abstract

Although the Paris Agreement in 2015 aimed to limit global temperature increases to below 2℃ and eventually to 1.5℃ to address the climate crisis, global temperature continues to rise. Developed countries have proposed a circular economy as a major strategy to tackle this issue. Detailed implementation methods include reusing, remanufacturing, recycling, and energy recovery. Remanufacturing has a greater potential to achieve high added value and carbon neutrality than other resource circulation methods. However, currently, no standardized method for quantitatively evaluating the greenhouse gas (GHG) reduction effects of remanufacturing exists. This study compares and analyzes recent research trends since 2020 on the calculation of GHG emission reduction effects from remanufacturing. It also examines international standards for environmental impact assessment, including GHGs and environmental performance labeling systems. This study derives the key factors for standardizing the calculation of the GHG emission reduction effects of remanufactured products.

기후 위기에 대응하고자 지난 2015년 파리협정에서 지구 온도상승을 2℃보다 아래로 유지하고 나아가 1.5℃ 아래로 억제하기 위한 목표를 설정하였음에도 불구하고, 지구 온도는 계속 상승 중에 있다. 실질적으로 이에 대응하기 위한 주요 전략으로 선진국들은 순환경제 실현을 제시하고 있으며, 세부 이행 방법으로는 재사용, 재제조, 재활용, 에너지 회수 등이 있다. 그중 재제조는 다른 자원순환 방법보다도 고부가가치 및 탄소중립 달성에 큰 잠재력을 가지고 있지만, 재제조를 통한 온실가스 저감효과를 정량적으로 평가할 수 있는 표준화된 방법이 부재한 상황이다. 이에 본 연구에서는 재제조에 의한 온실가스배출 감축효과 산정에 관한 2020년 이후의 최근 연구동향과 온실가스를 포함한 환경영향 평가 국제 표준 및 환경성적표지제도를 비교·분석함으로써 재제조품의 온실가스배출 저감효과 산정 표준화를 위한 핵심 요소를 도출하였다.
