  • 본 논문은 자동차에 부과된 환경세의 장기효과를 분석한다. 만일 정부가 소비자에게 자동차 배기가스에 포함된 오염물질이 대기오염 심화를 유발하는 외부적 피해의 화폐가치에 비례하도록 환경세를 부과하면, 일반적인 피구세와 마찬가지로 자동차운행이 사회적정수준으로 감소한다. 이와 같이 단기에 대기오염저감효과가 발생한다. 게다가 이러한 환경세는 소비자들로 하여금 조세부담으로 인해 오염물질을 적게 배출하는 자동차를 선호하도록 하며, 기업은 이러한 수요 변화에 대응하기 위해 청정 자동차를 생산하게 된다. 그러므로 환경세는 장기에 대기오염저감의 추가적 효과를 갖는다. 이러한 결과는 자동차가 수평적 그리고 수직적 차별화되어 있을 때 내무해가 존재하는 과점모형에서 시뮬레이션을 통해 얻게 된다.

  • This study analyzes the problems of environmental laws, development planning laws, Metropolitan Area Development Planning(MADP), and the level of environmental pollution at Pusan and Asan-Bay Metropolitan Area where MADP will be realized in the near future. In order to prevent the environmental pollution by realization of MADP, Environmental Impact Assessment Act and environmental impact assessment systems in Korea should be revised so as to reflect the followings. First, the impact of national landuse planning change on the environment should be considered at the beginning of environmental impact assessment procedures. Second, the overlapping and greater impact of many projects, whose part is the subject of environmental impact assessment, upon surrounding metropolitan area should be simultaneously evaluated and the environmental pollution protection and abatement alternatives must be made according to the above impact of the projects. Thirdly, total effluent regulation of water pollution, air pollution and solid wastes should be enforced based on the self-purification of the metropolitan area environment.

  • 본 연구는 자본과 노동의 요소투입물 증가가 환경오염의 증가를 유발하고 기술축적자체도 환경오염을 유발한다는 가설모형을 설정하고, 사회계획자모형과 환경오염방지활동이 이루어지지 않는 시장경제모형을 구축하여 이론모형을 도출한다. 도출된 이론모형을 이용하여 환경오염변수와 경제성장률(또는 국민소득 수준) 간에 선형이 아닌 비선형동학(nonlinear dynamics) 관계가 존재하는지를 분석하기 위하여 변수의 부드러운 곡면전환이 이루어지는 평활전이자기회귀모형(Smooth Transition Autoregressive : STAR)을 사용하였다. 서울시 산업생산지수와 대기오염도를 이용한 실증분석에서 경제성장률과 환경오염변수 간에 비선형 동태적인 관계와 비선형 그랜저 인과관계가 존재하는 것으로 나타나 서울지역에서의 환경쿠즈네츠곡선가설이 성립하고 있음을 간접적으로 확인하였다. 그러나 그 해석에는 한계가 있음을 지적하였다.

  • This paper asks the question: what choice of environmental policy instruments is efficient to reduce sulfur dioxide from stationary sources\ulcorner: In Korea, command and control has been a common way of controlling $SO_2-emissions.$ When compared to the non-incentive environmental policy instrument such as command and control, economic incentive environmental policy instrument has been the advantage of making polluter himself flexibly deals with in marginal abatement cost to develop environmental technology in the long view. Therefore, the application possibility of the incentive environmental policy instrument was studied in this research to realize the countermeasure for controlling of $SO_2-emissions.$ As a result, enforcement of the countermeasure such as flue gas desulfurizer by command and control would be suitable because power generation is performed by the public or for the public in source of air pollution and thus, economic principle is not applied to the polluter. In the source of industrial pollution, enforcement of fuel tax is found to be suitable for the countermeasure for the use of low sulfur oil in terms of the flexibility of demand for the price in the long tenn. For the permissible air pollution standards applicable to all air pollutant emitting facilities, enforcement of incentive environmental policy such as bubble, off-set, banking policy or tradeable emission penn its would be ideal in long terms according to the regional characteristics and the number and scale of air pollutant emitting facilities.

  • 미세먼지와 함께 질소산화물, 황산화물, 휘발성 유기화합물, 암모니아 비롯한 유발물질에 대한 동시 저감기술은 엄격해지는 환경규제와 실질적인 저감효과 제고를 위해 꾸준히 주목받아 왔다. 오존산화에 의한 비수용성 질소산화물 고속산화 공정은 전통적으로 적용되고 있는 선택적 촉매환원 공정에 비해 공간절약형 시스템 적용을 가능하게 할 뿐만 아니라 운영비용 절감 측면에서 매우 효과적인 방법으로 평가되고 있으며 황산화물을 비롯한 산성가스와 동시 저감이 가능한 공정 구현이 가능하다는 장점까지 있다. 본 논문에서는 오존 고속산화 공정에 대한 기술 이슈 및 개발 동향을 소개하며 향후 산업적 이용 확대를 위한 개발 방향에 대해서 고찰하고자 한다.

  • Since many previous studies reported the health effect of air pollution and indicated traffic as a major pollution source, significant policy efforts have been made to control traffic to reduce air pollution. However, there have been few studies that evaluated such policy implementation. In Seoul, Korea, the exclusive median bus lane system was implemented in 2004, and the metropolitan government applied air pollution reduction policies such as conversion of diesel buses to compressed natural gas buses and installation of emission control devices. This paper aimed to investigate the impact of the exclusive median bus lane system on air pollution reduction. Using hourly concentrations of particulate matter ($PM_{10}$) and nitrogen dioxide ($NO_2$) measured at 131 regulatory monitoring sites in Seoul and Gyeonggi-do for 2001-2014, we calculated annual and daily average concentrations at each site. We assessed the impact of the policy using differences-in-differences analysis by annual and daily average models after adjusting for geographic and/or meteorological variables. This method divides population into treatment and control groups with and without policy application, and compares the difference between the two time periods before and after the policy implementation in the treatment group with the difference in the control group. We classified all monitoring sites into treatment and control groups using two definitions: 1) Seoul vs. Gyeonggi-do; 2) within vs. outside 300 meters from the median bus lane. Pre- and post-policy periods were defined as 2001-2005 and 2006-2014, and 2004 and 2014 in the annual and daily models, respectively. The decrease in $PM_{10}$ concentrations between the two periods across monitoring sites in the treatment group was larger by $1.73-5.88{\mu}g/m^3$ than in the control group. $NO_2$ also showed the decrease without statistical significance. Our findings suggest that an efficient public transport policy combined with pollution abatement policies can contribute to reduction in air pollution.

  • Emission inventory (EI) is often recognized as a foundational pillar for air quality planning. In this manuscript, we reviewed national emission inventory (NEI) development processes in United States(US) and made recommendations for South Korean emission inventory development for the future. First, we examined history of emission inventory development in US while focusing on what has been success and failure. We noticed that, in general, emission reductions led to air pollution abatement although efficacy of same degree of reduction may not result in similar air quality improvement. Second, we described conventional approaches of developing NEI and differences between NEI and EI for State Implementation Plan which is required for air quality management in US. Last, we analyzed how US Environmental Protection Agency and counterpart agencies in states came up with a new plan for the next major regulatory modeling project. Based on our analysis, we conclude that early and steady participation of local governments will lead to effective and efficient emission inventory development and, in turn, will result in successful air quality planning that is necessary for actual air quality improvement.

  • Plasma technology has long been regarded as a key essential tool in many industrial and technological sectors. However, the advancement of plasma technology in marine applications has not been fully realized yet. Herein, we present a short overview on the recent trends in utilization of plasma technology for air-pollution treatment in marine diesel exhaust. Four non-thermal plasma system, including electron beam dry scrubber (EBDS), dielectric barrier discharge (DBD), electron beam-microwave (EB-MW) plasma hybrid system, and plasma-catalytic hybrid system, are described with emphasis on their efficiency in removals of $NO_x$ and $SO_x$ gases. Non-thermal plasma has the great potential to be an efficient and environmentally compatible technique in simultaneous removals of $NO_x$ and $SO_x$ gases from the exhaust of marine diesel engine in the future.
