배출권거래제 2차 계획기간(2018~2020년)부터 '국내기업 등이 외국에서 직접 시행한 CDM 사업'의 감축실적을 할당대상업체가 사용할 수 있게 되었다. 이에 시장의 이해관계자들은 한계비용이 낮으면서 많은 양의 배출권을 확보할 수 있는 '고효율 쿡스토브 보급사업'과 같은 해외 CDM 사업을 적극 추진하고 있다. 본 논문은 실물옵션 방법론을 활용하여 '고효율 쿡스토브 보급사업' 대한 외부사업자의 투자의사결정 모형을 개발하였다. 그리고 배출권 가격 불확실성하에서 '고효율 쿡스토브 보급사업'의 최적투자분기점(p^⁎) 도출 및 민감도 분석을 시행하였다. 그 결과 기준시나리오(PoA-S)에서의 최적투자분기점은 29,054원/톤으로 현재 배출권 현물 가격(p^⁎_spot)보다 낮아 고효율 쿡스토브 보급사업은 경제성이 있는 것으로 나타났다. 그러나 할당대상업체는 CDM 사업 추진 시 경제성뿐 아니라, 본 논문에서 분석한 투자유치국의 비재생 바이오매스 비율, 쿡스토브 교체 비율, 지분율, 사업기간 및 해외 외부사업 배출권의 사용 한도와 같은 위험요소도 고려하여 의사결정을 해야 한다. 그리고 외부사업자는 외부사업자의 고유 파라미터로 사업단계별 최적투자분기점을 도출하여 경제성 점검에 활용할 수 있을 것이다.
