The Low Carbon Path Calculator is an excel-based model to project greenhouse gas emissions from 2009 to 2050, which is based on the 2050 Pathways Calculator developed by the UK Department of Energy and Climate Change (DECC). Scenarios are developed to reduce GHG emissions in Korea at 50% based on 2005 levels by 2050 using a Low Carbon Path Calculator. They were classified in four different cases, which are high renewable, high nuclear, high CCS and mixed option scenarios. The objectives of this study are to compare scenarios in terms of GHG emissions, final energy, primary energy and electricity generation and examine the usefulness of that model in terms of identifying pathways towards a low carbon emission society. This model will enhance the understanding of the pathways toward a low carbon society and the level of the climate change policy for policy makers, stakeholders, and the public. This study can be considered as a reference for developing strategies in reducing GHG emissions in the long term.

전 세계는 기후변화 대응과 경제성장을 목표로 하는 저탄소 경제로의 전환을 위해 다양한 온실가스 감축정책과 재생에너지 확대정책을 시행하고 있다. 본 연구에서는 전 세계 국가들을 대상으로 다양한 온실가스 감축 정책 및 재생에너지정책들이 동시에 시행되는 국가들의 경우 단일한 온실가스 감축 정책이나 재생에너지 정책만이 시행되는 국가들보다 추가적인 온실가스 감축이 이루어졌는지를 실증 분석하였다. 전 세계 온실가스 감축 정책 및 재생에너지 확대 정책을 실시하고 있는 나라들을 대상으로 한 패널계량분석을 실시한 결과, 온실가스 감축정책 혼합이 온실가스 추가 감축에 일부 기여하는 것으로 나타났으나, 모든 정책 혼합이 추가적인 온실가스 감축을 유도하지는 않는 것으로 분석되었다. 즉, 배출권거래제도와 재생에너지 공급의무화제도(RPS, Renewable Portfolio Standards)의 정책 혼합과 탄소세제와 발전차액지원제도(FIT, Feed-in Tariff)의 정책 혼합만이 추가적인 온실가스 감축효과를 거둘 수 있는 것으로 나타났다.

Following public expectations from the emergence of an international agreement with greater legal force after the expiration of the 2012 Kyoto Protocol, Korea is also making efforts to effectively and systematically initiate the mitigation policy and enforce the terms of the international climate change agreement. The majority of domestic industries are candidates for greenhouse gas emission regulation, thereby requiring the proposal of a method that effectively reduces environmental contaminate substances released from railway facilities, following the prediction of an increase in railway usage as an environment-friendly transportation method in the future. Accordingly, this study has quantitatively calculated the amount of released environmental contaminates through the life cycle assessment (LCA) on railway facility constructions, and has evaluated the environmental load and the amount of greenhouse gas emissions through the resulting values. The results of the LCA analysis showed that the amount of environmental load was the highest at the early stages of material implementation and construction, and that the value of global warming was viewed as the highest among the effects. As officially announced by the World Meteorological Organization and the United Nations Environment Program that $CO_2$ is the main culprit of global warming, the analytical values confirmed that the amount of $CO_2$ emissions accounted for more than half of the released greenhouse gases at 2.90E+04tons. The environmental load and $CO_2$ emission rates analyzed in this study are judged to be used in the deduction of the optimum environment-friendly method and quantitative environmental effect of railway facility constructions in the future, as the values can be evaluated based on their degree of environment friendliness.

기후변화에 대응하기 위하여 지역, 국가, 세계 차원에서 온실가스 배출량 감축 목표가 논의되고 있다. 정부가 2009년에 국가 중기 온실가스 감축목표를 발표한 이후, 16개 광역시 도 또한 자체적으로 2020년 온실가스 감축목표를 수립하였다. 본 연구는 16개 광역시 도의 온실가스 배출 특성과 2020년 온실가스 감축 목표 및 이행 전략을 검토 및 비교하였다. 대부분의 광역시 도는 소비에 기반한 배출량 산정 방식을 택하고 있었다. 감축목표는 대체로 2020년까지 온실가스 총배출량을 배출량 전망치 대비 30% 감축하는 목표를 수립하고 있었지만, 일부 광역시 도에서는 온실가스 순배출량을 과거의 특정년도 대비 감축하는 목표를 채택하고 있었다. 2020년 배출량 전망이나 과거 특정년도의 배출량, 그리고 1인당 배출량 등 채택하는 지표에 따라서 광역시 도별 감축목표의 강도는 다르게 평가되었다. 광역시 도별 배출량 특성에 따라서 핵심적인 감축 이행 부문 또한 차이를 보였다. 광역시도의 배출량 산정과 감축목표 수립의 개선 방안으로, 광역시 도 온실가스 인벤토리 개발을 위한 세부 자료에 대한 정부와 광역시도간 공유, 상향식 및 하향식 분석 모형 활용, 전망치 및 기준년도 대비 감축목표 제시, 기후변화대응계획과 에너지계획의 통합 또는 연계 수립 등이 요구된다.

Pollution emissions from international shipping and port activities have a significant impact on public health and global climate changes. The purpose of this paper is to review the status of pollution mitigation measures implemented to date in port industry and find out some implications for Korean ports. For this aim, the clean air strategies of the world major ports including six USA ports (Los Angeles/Long Beach, Now York/New Jersey, and Seattle and Tacoma), two European ports (Rotterdam and Gothenburg) and Busan Port were considered. Various measures to reduce emission from ports are evaluated by sectors-ocean going vessels, cargo handling equipments, truck and rail-, on the basis of categories such as reduction control technologies, operational changes and market-based measures. The policy implications of this paper are as follows. First, Clean Air Act Plans of Korean ports are required as soon as possible. Second, integrated approach is required to reduce emission effectively. Finally, the effect of port-related emission reduction can be maximized when various measures are conducted on a regional basis including neighboring ports. Furthermore, regional or global-based approach is useful to guarantee the level playing field among ports.

Non-Annex I parties announced the voluntary emission reduction targets including the U.S. in the conference of party. NAMAs would be focused to solve the negotiation clue for the post-kyoto regime. Since the country would not be involved in Annex I parties, the voluntary carbon market would be created for the greenhouse gas reduction targets. According to Bali Roadmap, voluntary carbon market should be constructed by the MRV manners since this country does not belong to Annex I parties. Carbon point system would be proposed by the ways of the international voluntary emission reduction credit. The voluntary carbon market should involve the potential GHG reduction credit and link with the ETS in the country. This study proposed the way of linkage between ETS and voluntary carbon market including the carbon-point system.

Sri Lanka has strongly understood the importance of mitigation of climate change and various measures have been taken. To tackle the climate change, after ratifying Paris Agreement, Sri Lanka has pledged to reduce her greenhouse gas emission in the energy sector by 20% (16% unconditional and 4% conditional) by 2030 based on the BAU scenario. Simultaneously, the government introduced its new energy policy and strategies in 2019 with a vision of achieving carbon neutrality by 2050. This paper survey related key government documents, policies, reports, and academic articles to investigate opportunities for the private sector to invest large scale solar power deployment (10 MW or above) and to get support from climate finance under article 6 of the Paris Agreement. It has found, growing concern on the environment, energy security issues and increase import expenses for fossil fuels are the main influencing factors to move renewable sources. Further, government investment and FDI both have gradually decreased in the energy sector. Therefore, an alternative financing mechanism is needed. Although the private sector allowed investing in the energy sector since 1996 with the introduction of IPP (Independent Power Producers), it could not make considerable progress on involving large scale solar utility projects. This has revealed government policy is not aligning with the long term generation plan of the electricity sector. The study has also found, it needs more strategic road map, coordination with different institutions, monitoring system to enhance large scale solar contribution.

Globally, consumers' enormous and increasing appetite for meat is one of the biggest causes of climate change because livestock industry emits more greenhouse gas than transportation. The purpose of this study is to analyze consumer awareness about the impact of meat consumption on sustainability in response to climate change. Based on the theory of planned behavior, the attitudes, subjective norms, perceived behavioral control, prior knowledge, and risk perception variables were analyzed to evaluate the impact of climate change awareness over consumer behavior on meat consumption. Major findings are as follows: consumers were aware of climate change but has made few changes to their meat consumption. In addition, changes in meat consumption were found to be caused by health safety concerns, such as disease outbreaks. Significant variables related to meat consumption patterns associated to climate change impacts were household income, age, attitude, subjective norm, perceived behavioral control, and prior knowledge. These results suggest some implications for policy. There is a need for public relations and education to make the public aware of and better understanding of link between climate change and diet. Also, government should make efforts to raise awareness of mitigation of climate change such as comprehensive food labels which are identifying lesser impacts on climate and better dietary guideline instructions which would include coping with climate change.
