초록

자동차에서 배출되는 대기오염 물질로 인하여 인체 건강과 일상 활동이 막대한 피해를 입고 있어 대기오염 물질을 저감하기 위한 새로운 친환경 자동차나 자동차 개조 장치의 개발과 적용이 필요하다. 하지만 이러한 기술의 환경적 편익과 비용이 기존의 경제성 평가에서는 반영되지 않아 친환경기술의 보급에 장애가 되고 있다. 본 연구에서는 자동차에서 발생하는 대기오염 물질이 우리 사회에 끼치는 사회적 비용을 고려하여 친환경기술의 경제적 타당성을 평가하는 방법론을 제안하고, 이 방법론의 적용성과 타당성을 보여주기 위해 사례연구를 실시하였다. 현재 국내에서는 대기오염 물질의 사회적 비용이 평가되지 않았기 때문에 유럽에서 평가한 사회적 단위비용을 바탕으로 국내 자동차 배출가스 측정기준, 구매력 지수, 환율, 소비자 물가지수를 이용하여 국내에서 활용가능한 사회적 단위비용을 도출함으로써 경제적 타당성 평가에 활용할 수 있게 하였다. 사례연구에서는 경유버스를 개조하여 경유와 압축천연가스를 함께 사용할 수 있도록 하는 혼소시스템 기술에 대해 대기오염 물질의 사회적 비용을 포함한 경제성을 평가하였다. 본 연구에서 제안된 방법론은 자동차뿐만 아니라 다양한 친환경 기술, 사업, 정책의 타당성을 평가하는 데 활용될 수 있다.

Air pollutants have a high impact on everyday life as well as on human health; therefore, new technologies such as low-emission vehicles and add-on systems for air pollutant reduction are needed for our society. However, the environmental benefits and costs of those technologies are not taken into account in existing economic feasibility assessments, which is a barrier that needs to be overcome for green technology to achieve wide dissemination and fast penetration in the market. Thus, this study develops a methodology to assess the economic feasibility of an air pollutant reduction technology by taking into account the social costs from air pollutants and carries out a case study to validate the methodology. Because the social unit costs for air pollutants have not been evaluated yet in South Korea, the methodology uses the social unit costs evaluated for the European Union that are then converted to those for South Korea based on the measuring criteria for vehicle emission gases, parity purchasing price, foreign currency exchange rate, and customer price index. The social unit costs for South Korea are used to assess economic feasibility. A case study was performed to assess the economic feasibility of a dual fuel system using diesel and compressed natural gas by taking into account social costs from air pollutants as well as economic costs. This study could contribute to assessing the true economic feasibility of green technology, projects, and policy related with air pollutant reduction.
