A green market refers to a market that consists of environmentally aware consumers. A few researches have been carried out on the effects of environmental policy measures in a green market. These existing researches were based on a vertical differentiation model with firms' price-setting behavior, and derived that unit emission standard and environmental product taxes could not reduce the amount of pollution emission. This note considers a vertical differentiation model with firms' quantity-setting behavior, and shows that, contrary to the previous result, the amount of pollution emission is reduced by the introduction of unit emission standard. This implies the importance of the nature of firms' interaction in figuring out the pollution abatement effect of environmental policy measures in a green market.

오늘날 우리사회는 환경변화와 기후 위기 가속화로 인하여 삶의 질 악화는 물론 인류 생존까지도 걱정해야 시기에 이르렀는데, 이러한 변화의 주범인 온실가스의 75%가 도시에서 발생되고 있다(Global Sustainable Development Repor, 2019), 이에 국제 사회는 도시 중심의 녹색 전환 정책 추진 중인데, 우리나라는 2017년부터 '도시재생뉴딜사업'을 추진하고 있다. 이에 본 연구는 지자체가 주도적으로 환경성과 창출 방안을 마련, 도시의 지속가능성 높이는데 일조하고자 탄소중립 선도 도시 사례와 도시재생의 문제점을 살펴봄으로써 도심 내 과밀화 문제와 탄소배출 해결 방안을 제시하였다. 당초 '도시재생뉴딜' 사업은 도시의 다양한 니즈를 충족시키기 위하여 시작되었으나, 최근에는 도시 노후화와 탄소배출 문제에 대응하기 위하여 '그린도시', '친환경 도시'를 지향하고 있다. 그러나 이를 뒷받침할 법·제도의 제·개정 및 이를 바라보는 이해관계자의 시각 전환이 이루어지지 않아 크고 작은 많은 문제점이 발생하고 있다. 도시재생의 첫 번째 문제점은 정책지원의 30% 이상이 일반근린형에 집중됨에 따라 주거형 도시재생 양상을 띄고 있다는 점이다. 이는 임기가 제한된 지자체장이 가시적인 성과를 위하여 도시 내 인프라 확충에 집중한 결과로 지속가능한 도시재생을 저하시키는 요인이 되고 있다. 두 번째, 도시재생 뉴딜사업이 계획수립과정에서 지속가능성에 대한 검토와 환경성 평가에 대한 고려 부족으로 기후 위기 대응에 미흡한 실정이다. 노후 도시의 주거 과밀화 문제를 해결하고 효과적인 도시 탄소 감축을 위하여 건물 - 마을 - 도시 등 여러 공간 단위의 온실가스 배출량 감축 전략 수립이 필요하다. 세 번째, 치·이수 위주의 도시재생 뉴딜사업으로 탄소 중립 대책이 미흡하다. 대응 방안으로는 자원의 관점에서 물 소비 감소 촉진 및 재생에너지 증가 전략이 필요하다.

This study estimates baseline greenhouse gas emissions from transport sector when a new town is developed. It has adopted a general greenhouse gas estimation model developed by Schipper, celine, Roger(2000) for the estimation, and showed how various transport related statistics can be utilized in detail. Particularly, it has produced unit greenhouse gas emission factor per vehicle types, vehicle-km, and trip-km. To evaluate effects of greenhouse gas reduction policies, it has calculated how much emissions will be reduced from bicycle promotion. It has turned out that about 369 thousand tons of carbon dioxide will be emitted from transport sector once the 1st Geomdan New Town is developed in Incheon metropolitan city. If the policy of bicycle promotion can attract people to use bicycle as much as 5% of total trips, then it can reduce about 1,869 tons of carbon dioxide.

Today, more than thiry countries around the world are designated as a mandatory GHG(GreenHouse Gas) emissions country from the UNFCCC(United Nations Framework Convention on Climate Change). Korea is also possible to designate a mandatory GHG emissions country after Second mandatory emissions which will be started in 2013. Accordingly, Korea government has made efforts to reduce GHG and has enforced energy-related policies to deduce building energy. But there is no process such as providing of existing building improvement recommendations or expert verification for building remodeling in Korea energy-related policies compared with policies in other countries. For this reason, improvements of Korea which divided governments and city provinces are suggested. However suggested improvements are directions, so additional research is needed for detail methods.

최근 대두되고 있는 중요한 문제 중 하나인 기후변화협약에 의하여 온실가스 배출량에 대한 감축 및 규제가 실시되고 있으므로, 우리나라에서도 이에 대한 대비를 하지 않으면 안 되며, 유가가 급등하고 있어 에너지 소비를 감소시키는 정책을 적극적으로 수행해 나가야 한다. 전력시스템이 대형화되고 더욱 복잡하게 구성되면서, 전력손실 감소 및 전압관리 차원에서 부하 역률 관리의 중요성이 새롭게 부각되고 있다. 따라서 온실가스 배출량 감축 효과를 반영하여 우리나라의 전력시스템의 적정한 부하역률 기준치가 새롭게 조정될 필요가 있다. 본 논문에서는 온실가스 배출량 감축 효과를 반영하기 위한 기초연구로서 적정 부하역률을 산정하기위한 기법을 제시하고, 이산화탄소의 배출량 감축 효과를 반영하지 않을 때와 반영할 때의 적정 부하역률이 어떻게 변화하는지를 주어진 하나의 전력 시스템을 사용하여 분석한다.

미세먼지 등 대기오염에 대한 국민적 관심 증가로 정부에서는 2022년까지 국내 배출량 30% 감축을 목표로 하는 '미세먼지 관리 종합대책'을 수립(2017년)하였으며, 국제해사기구(IMO)는 선박의 대기오염물질 배출량 감소를 위한 규정을 강화는 등 대기오염물질 감축을 위한 다양한 노력이 추진되고 있다. 그러나, 부산항을 포함한 부산지역의 미세먼지 농도는 선진국 및 WHO 기준에 비해 여전히 2~3배 높은 수준으로 부산의 주요산업인 부산항을 관리 운영하는 주체인 부산항만공사는 '부산항 미세먼지 종합대책'을 수립하여 추진하고 있다. 본 논문에서는 부산항 내 운영 중인 항만 내 대기오염측정소 데이터를 포함한 항만 인근지역과 타항만의 미세먼지 농도를 분석하였으며, 부산항만공사에서 추진한 항만 하역장비 대기오염물질 배출량 조사결과와 '야드트랙터 LNG 연료전환사업', 'AMP설비 설치사업' 등 '부산항 미세먼지 종합대책'과 그 성과를 소개하고 있다.

Most studies on $CO_2$ abatement cost with a computational general equilibrium(CGE) model focus on a specific country. On the contrary, this study compares and analyses the $CO_2$ abatement cost functions across 20 countries, consisting of OECD countries, China and Brazil, with a CGE model. For this purpose, we estimate the GDP loss from $CO_2$ emission reduction, assuming the 4 sector model. Our findings show that those cost curves are convex but different among the countries. However, despite of the difference in the cost curios, we have found that one group of countries has the relatively constant average abatement cost and the other group has the increasing average cost. The reason why such a pattern occurs is explained in terms of the variations of value-added and $Co_2$ emission coefficient by sector across the countries. As an environmental policy implication, this study presents information about which country is similar to one another in terms of the abatement cost.

This research first reviewed and analysed the current domestic situation of the voluntary agreement implementation and then it developed the policy implementation scenarios which will be applied to the model, KORTEM_ V.2. The model, consisted with 83 industries and commodities, examined the economic and environmental impacts of this policy instrument. Depending on the efforts of participating sectors and agents for fuel substitution and energy efficiency improvement, it has been evaluated that the voluntary agreement could be the "no-regret" policy. In other words, if the participating sectors and agents can achieve the voluntary energy conservation and emission reduction target without the negative impact on output level, the reduction of national emission will be achieved by creating the economic benefit, simultaneously. Therefore, for the successful implementation of voluntary agreement, this study emphasized the importance of expansion and strengthening of the current financial and institutional support for participating sectors and agents.

This paper estimate the $CO_2$ reduction potential that can be achieved by improving the technical efficiency of input factors in the manufacturing sector. Technical efficiency in each manufacturing firm was estimated using the DEA technique. Depending on the returns-to-scale assumption selected, average technical efficiency was estimated to be between 0.467 and 0.643. These estimates suggest that, when the efficiency of electricity consumption in the manufacturing sector is improved, the overall $CO_2$ emissions can be reduced by 17.1-25.5%. Recently, the Korean government has adopted a low-carbon-green-growth policy with the goal of reducing greenhouse gas emissions by 30% below the BAU level by year 2020. The analysis of the paper suggests that this goal can be achieved through improved efficiency of electricity consumption.

The 2015 Agreement, an initial architect of the Post-2020 Regime, is expected to be adopted at the twenty-first session of the Conference of Parties to be held in Paris in 2015. We discussed key characteristics of the Post-2020 Regime and applications of differentiation which is most contentious issue in the Post-2020 negotiation. In the Post-2020 Regime, automatic ambition increases of Parties could be accomplished through applications of the circular nature of Intented Nationally Determined Contributions (INDC) as well as the progression of mitigation efforts. In terms of differentiation, it would be better to advocate a new method to applying differentiation in the Post-2020 Regime taking into account our own national circumstances. Specifically, promotion of self-differentiation which fits nearly with the philosophy of INDC could be an alternative. In order to promote self-differentiation, rules to apply self-differentiation needs to be devised, and the purpose of such rules should be the ambition increase.
