기후변화는 이제 환경의 문제를 넘어 정치적, 경제적 문제로 진화되어 있는 상태이며, 인류 생존을 위한 환경적 문제로서의 중요성 뿐만 아니라 국가 경제의 보호와 성장에 중요한 지렛대 역할을 하게 되었다. 정보통신기술(ICT)은 기후변화 문제에 대처하여 다양한 산업 분야에서 기술적 해결책의 하나로써 활용되어 저탄소화를 촉진시킬 수 있는 효과적 수단으로 인식되고 있다. 이에 따라 관련 국제표준화 활동이 2008년부터 시작되어, 2009년에 표준화의 기반이 마련되었고, 2010년부터 본격적인 표준 개발 활동이 시작될 것으로 전망된다. 이에 대한 전반적인 현황과 전망을 소개하도록 한다.

The policy aimed at introducing a Bonus-Malus system to reduce GHG and raise the market share of small cars is scheduled to go into effect in South Korea in 2020. Although the policy was originally planned to be enforced from 2015, the Ministry of Trade, Industry and Energy argued that the system brings low reduction effect and relative disadvantage to domestic small cars and brought arguments in 2014. As a result, the enforcement was pushed back. Related studies are mainly focused on offering statistical estimation of the policy's effect to support the arguments, and few theoretical studies were published given that there was not enough time until 2015 back then. The author approached the issue with mathematical modeling in order to give theoretical basis for sophisticated empirical studies. If car suppliers have market power and strategically set their prices, the impact of Bouns-Malus on car prices would be lower than what was originally intended. In case only a part of the car market loses its market power, the effect of the policy would be improved. Assume that the Bonus-Malus is currently at an optimal level and the car market structure is undergoing changes, then the direction of the new optimal level would depend on the elasticity of demand of each market and substitute elasticity. For example, if the car market becomes more monopolistic while the demand for big cars is elastic, demand for small cars is inelastic and substitution elasticity is low, then the new optimal level of Bonus-Malus should be higher.

Sustainability has already become one of the most important innovation policy agendas in many countries. Korea has tried to emulate this global trend in various forms, unfortunately with little success. A very strong tradition of centralized administration in Korea has meant that local communities and municipalities have remained more or less passive in tackling their own sustainability issues and problems. In recent years, with the impetus of huge democratization attempts in Korea since the late 1980s, there have been some local attempts to remedy these imbalances since the early 2000s. A series of local experiments to try and test green alternatives against the very hostile environment have been implemented, with varying degrees of success. This study analyzed cases of transition experiment to sustainable socio-technical system such as MUSIC project, Low Carbon Green Village and Citizens' Sunlight Power Stations. To draw politic meanings for sustainable socio-technical system, these content, process of conversion and feature were examined.

After reviewing the concept and previous studies related to green ports, this study analyzes the implications of green port policy of advanced ports in foreign countries and analyzes problems in terms of environmentally-friendly green port policy for Ulsan port, and to present sustainable green logistics establishment measures. The literature survey and Benchmarking methods are adopted as research methodology and the results are as follows. First, the pan-government climate change response management system, legislation of relevant laws, implementation of fiscal support policies, and roadmaps should be established. Second, the foundation for eco-friendly green growth should be established through the discovery of business models in conjunction with leading industries in the Southeastern Metropolitan Economic Area. Third, the Ulsan Port Greenport, such as AMP, in-port LNG propulsion ship, and ESI vessel incentive, should be built. Fourth, a low-carbon, high-efficiency sea-shuttle service shall be established through the introduction of the sea-shuttle service along the sea route. Fifth, energy self-reliant ports, including all institutions in the metropolitan Ulsan port area that have exceeded the level of Ulsan port Authority, should be built. Finally, water-type ports need to be built through the creation of coastal forests, the purification of marine water quality, and the introduction of colors to port.

This study analyzed the determinants of carbon dioxide emissions through the expanded STIRPAT model using panel data from 16 metropolitan cities and provinces in Korea from 2000 to 2019. After testing cross-sectional dependence and coefficient heterogeneity of panel data, we performed analysis using MG, CCEMG, and AMG estimation methods reflected these characteristics. The results of analysis using the AMG estimation method are as follows. The coefficients of income, population, and energy intensity were statistically significant with a positive sign, but urbanization was statistically insignificant. Reduction of carbon dioxide emissions in Korea can be achieved through an increase in energy efficiency and sustainable economic growth. It is necessary to establish a policy that can contribute to sustainable economic growth by inducing productivity improvement through technology innovation reducing carbon dioxide emissions in the long-term as well as building a low-carbon society through active development of carbon dioxide reduction technology.

Recent lifeline with Internet and smart-phone is a new ICT-based revolution that has transformed the structure of economics and business activities in digital economy. This paper deals with some economic perspectives on the conceptual concerns on transaction costs and its applications to energy and environments, and glocalization strategies of e-business. First, we consider substantial differences between offline and online channel transactions and categorize three different aspects of transaction costs in the purchasing process in both channels. Second, we examine the impacts of e-business that affect sustainable environments and provide some considerations on energy savings, product-process design, and logistics. Finally, we present some opportunities and challenges posted by global e-business and outline the economics of networking in achieving enhanced performance and competitive advantage through glocalization strategies of e-business.

지속가능한 발전과 저탄소 녹색성장의 개념이 대두되면서 우리나라를 비롯한 주요 선진국은 자국의 화석연료 의존도를 낮추고 대체에너지로 환경친화적이며, 청정에너지로 각광받는 신 재생에너지의 활용에 경제적, 정책적 지원을 아끼지 않고 있는 실정이다. 실제로 유럽에서는 바이오매스의 일종인 우드칩을 활용한 가정용 보일러가 보급되고 있으며, 동남아시아에서는 열대식물을 이용한 저온열분해를 활용하여 바이오디젤을 생산하고 있다. 우리나라의 경우 대부분의 바이오매스는 발생되는 임야에서 재이용되거나 경제성이 있을 경우에 운송되어 재활용되고 있으며, 임부목과 같은 일부 바이오매스는 수익성이 없어 발생현지에 방치되는 경우도 있다. 본 연구에서 주목한 왕겨의 경우 미곡종합처리장에서 대량으로 발생되지만 그 활용도에 있어서 축적된 바이오에너지에 비해 에너지회수율이 저조하다고 할 수 있다. 왕겨는 임야에서 발생되는 폐목재나 다른 바이오매스에 비해 함유되어 있는 수분이 적고(12%), 휘발분의 함량이 많으며(58%), 고정탄소(17%), 회분(13%)로 열분해/가스화에 적용가능하다. 본 실험에서 생산된 합성가스의 활용방법으로는 보일러를 이용한 스팀 및 전력생산, 가스엔진을 이용한 전력생산, 폐열회수 등이 있으며 생산된 합성가스를 활용하기 위해서는 오염물질의 정제특성에 대한 연구가 선행되어야 한다. 따라서 본 연구에서는 합성가스 내에 존재하는 분진, 타르, HCl, HCN, $NH_3$의 제거효율을 조사하였다.

Carbon productivity is an efficiency concept, well suited to maximizing product/service(economic) value of firms and minimizing environmental impact($CO_2$ emissions). This study investigates the causal relationship between carbon productivity (eco-efficiency) and financial performance in Korean firms. The result shows that firms improving carbon productivity are able to gain superior financial performance. The analysis also show that changes in financial performance have a positive impact on the improvement of carbon productivity. However this study reports that carbon productivity does not have a long-run impact on financial performance and vice versa. Finally, the results also show that differences exist in the relationship between carbon productivity and financial performance when grouped by industry characteristics.
