The objective of this study was to assess the feasibility of a landfill project aimed at reducing greenhouse gas (GHG) from Puerto Cortes Landfill in Honduras ("Project"). The feasibility study involved surveying the status, composition and amount of waste entering the landfill, and projecting GHG emissions from the landfill. A projection of the GHG emissions with the IPCC model and based on the survey results indicated that the period 2027 to 2041 would see a total GHG emission reduction of 506,835 ton-CO₂/year, with a mean yearly GHG emission reduction of 33,789 ton-CO₂, assuming landfill gas collection is implemented, The findings of the study are expected to serve as basic data for deciding about whether and how to proceed with the Project.

This study explores what potential future greenhouse gas allocation schemes might mean for OECD countries, and discusses a number of concepts of equity, examines three specific burden sharing rules and formulae. The results indicate that Korea reduces its emission from 8.1% and 19.8% which is 34.9-85.8 million tons of $CO_2$ emission on the assumption that the overall level of abatement remains 20% of total 2000 OECD emissions.

본 논문에서는 우리나라 2030년 국가 온실가스 감축목표(NDC*, 291백만톤 감축)달성 및 2050년 탄소중립 목표 달성을 위해 필연적으로 수반되는 천연가스 내 수소 혼입에 따른 안전성확보 방안과 수소혼입에 따른 국민 불안감 해소 및 수용성 제고를 위한 대안을 제시하고, 해외 사례를 연구 하였다. 탄소중립은 온실가스(이산화탄소 등)의 배출량을 최대한 줄이고, 남은 온실가스를 흡수, 제거해서 실질적인 배출량이 "0"이 되는 것을 의미하고, 수소혼입은 도시가스의 주성분인 메탄 연소시 발생하는 CO₂를 최소화하기 위해 수소(H₂)를 도시가스에 일정비율 혼합하는 것을 말한다. 본 연구에서는 수소 혼입 시 우려되는 수소취성 및 배관내구성 문제와 수소 특성인 작은 입자로 인한 누출 위험성, 고층에서 메탄과 수소가 분리되는 현상 등에 따른 문제를 도출하고 이에 대한 안전관리 방안도 함께 제시하였다. 또한, 도시가스 배관에 수소 혼입시 천연가스 대체를 통한 온실가스 감축 및 기존 배관망 사용을 통한 경제성 분석결과와 국가 온실가스 감축에 어느 정도 기영할 수 있는지도 함께 기술하였다.

Global climate change caused by greenhouse gases(GHG) is getting serious. To prevent this, countries around the world are regulating GHG emissions. Korea has decided to reduce GHG emissions by 37% compared to BAU (Business As Usual) by 2030. The transportation sector accounted for 18.58% of the domestic GHG emission, and roads accounted for 93.75% of the total. Public transportation is also included in the target of GHG reduction, and this study was conducted to reduce GHG emissions of bus public transportation, which can reduce GHG emissions while reducing the cost of road transportation. In this study, a simulation was conducted to predict the optimal GHG emission compared to the waiting time of passengers by adjusting the bus dispatch interval by implementing a greenhouse gas simulation model using Any Logic. If a more precise model is implemented in the future, it is expected that it will be used to reduce bus GHG emissions.

A bottom-up approach has been conducted to estimate greenhouse gas (GHG) emission and to analyze the marginal abatement cost for the Korean horticulture energy sector. With the systematically derived activity and energy balance data, the BAUs have been estimated, along with the marginal abatement cost over the period 2010 through 2030. The result from the marginal abatement cost analysis may provide general guidelines and procedures for the establishment of GHG abatement polices.

It is known that energy usage from Korean Universities was growing rapidly in the early 2000s. But since 2011, the change was caused by GHG emissions regulation enforced by the government. The purpose of this research was to find the characteristics and trends of greenhouse gas emissions from major universities in Korea according to the each university's data and information. The result shows that GHG emissions from University have increased steadily prior to enforcement by 4-5% annually, but the rate of increase marked 0.5~1% in 2011~2013 is the season of emission regulation and the total amount of emissions decreased 3%~5% in 2014~2015 while preparing an emissions trading scheme. Therefore we can say that the enforcement of GHG reduction such as energy target management system makes a visible effect at least in the University sector that level of GHG emissions is from $75kg/m^2$ to $58Kg/m^2$ for seven years. Another result says that the size of research fund is the main factor that affects the amount of GHG emissions before 2011, but the size of building area has been a new factor influencing the GHG emission since 2013. Thus we suggest that the criteria for evaluating the level of GHG emission from University is suitable if it is based on the building area intensity.

기업들은 온실가스 배출권거래제를 대비하여 철저한 준비가 필요하다. 에너지 온실가스 경영을 적극 도입하여야 하며 사업장내의 감축이행에 소요되는 한계비용과 배출권 시장 가격 등을 고려한 다양한 감축 옵션을 검토하여 기업경쟁력 저하를 방지하고, 자사의 강점을 살려 기후변화 시대에 맞는 비즈니스모델 도출을 위한 준비에 힘써야 할 것이다.

This paper analyzes the economic and environmental impacts of domestic policy to reduce greenhouse gas emissions by focusing on carbon tax, domestic emissions trading and the mixture of these policies. By utilizing a dynamic CGE model, KORTEM, this study shows that the economic cost under carbon tax is projected to be higher than that under emission trading. It is because under carbon tax scheme each emitter in economy must meet its emission target regardless of the abatement cost. On the other hand, emission trading allows emitters to reduce the marginal cost of abatement through trading of emission permits. In designing policy portfolio to address the climate change problem in Korea, therefore, this paper proposes the introduction of domestic emission trading scheme as the main domestic policy Instrument.

The policies and researches for the reduction of greenhouses gases have been performed according to"Paris Agreement". Because South Korea is the $6^{th}$ biggest greenhouses gas emitter in the world, the Korea government has prepared the strategies for the reduction of greenhouse gases. The development of CCUS (Carbon Capture Utilization and Storage) technology is necessary to reduce greenhouse gases. Therefore, the CCUS has been studied by many contries in the world. In this work, the trends of CCUS technologies R&D has been shortly investigated.

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.
