A 'Resource recycling society' is the common goal to reduce environmental impact from human activities and to conserve natural resources. The Resource-Recycling Waste Management is necessary to explicitly show objectives, and to evaluate the achievement level gained by school administration. In this paper, focusing on resource-recycling school waste management, three indicators are designed to evaluate the present conditions of school waste management, which include evaluation of school policy, waste management and education for waste management by school administration. Each indicator is made up of three or four questions that are supposed to be answered by school managers, teachers and students. Questionnaire surveys, which is based on the resource-recycling school waste management indicators, were carried out in elementary school, middle school and high school in the National Capital region. The resulting of indicators well describe the situation of school waste management among these schools. Influential strategies towards resource-recycling school waste management have been found in analysis.

Growing stringent global regulations in Korea poses a threat to corporate sustainability. Companies must respond strategically to navigate these regulations and avoid greenwashing. Objective of this research was to analyze how Korean companies are responding to the global trend of reducing plastic use and propose improved management strategies. Seven indicators were developed to assess companies' post-plastic strategies and applied to analyze the sustainability reports of Amore Pacific and LG Household & HealthCare. These indicators included, 1) disclosure of plastic raw materials used by weight or volume, 2) disclosure of recycled plastic raw materials used by weight or volume, 3) disclosure of waste recycling, reuse amounts, and disposal using waste treatment method 4) strategies to reduce environmental impact of plastics, 5) plastic packaging, reduce, recycle, reuse, and composting (in the real environment), 6) plastic management roadmap for the circular economy, and 7) education for sustainable plastic management. Based on the review of considered companies, we propose in-listed sustainable plastics management strategies: disclosing the ratio of plastic raw materials and recycled raw materials for all products, considering recycling rate throughout the product value chain, and not only for the production phase, reviewing carbon dioxide emissions based on life cycle assessment rather than reducing plastic consumption, studying the biodegradability of biodegradable plastics in natural environment such as soil, considering the consumer's perspective.

Carbon finance is the investment in Greenhouse Gas (GHG) emission reduction projects in developing countries and countries with economies in transition within the framework of the Kyoto Protocol's Clean Development Mechanism (CDM) or Joint Implementation (JI) and with creation of financial instruments, i.e., carbon credits, which are tradable in carbon market. The additional revenue generated from carbon credits will increase the bankability of projects by reducing the risks of commercial lending or grant finance. Meantime, it has also demonstrated numerous opportunities for collaborating across sectors, and has served as a catalyst in bringing climate issues to bear in projects relating to rural electrification, renewable energy, energy efficiency, urban infrastructure, waste management, pollution abatement, forestry, and water resource management. Establishing additionality is essential for successful CDM project development. One of the key steps is the investment analysis. As guided by UNFCCC, financial indicators such as IRR, NPV, DSCR etc are most commonly used in both Option II & Option III. However, economic indicator such as Economic Internal Rate of Return(EIRR) are often overlooked in Option III even it might be more suitable for the project. This could be due to the difficulties in economic analysis. Although Asian Development Bank(ADB) has given guidelines in evaluating EIRR, there are still large amount of works have to be carried out in estimating the economic, financial, social and environmental benefits in the host country. This paper will present a case study of a CDM development of a 18 MW hydro power plant with carbon finance option in central Vietnam. The estimation of respective factors in EIRR, such as Willingness to Pay(WTP), shadow price etc, will be addressed with the adjustment to Vietnam local provincial factors. The significance of carbon finance to Vietnam renewable energy development will also be addressed.

This study aims to provide public sectors with eco-efficiency information. To implement the purposes of the study, environmental and economic variables of Eco-Efficiency were identified through decision tree model, then the relative Eco-Efficiencies of 243 public sectors were evaluated through input-oriented DEA (Data Envelopment Analysis) model. Specifically, the amount of public purchasing per a staff and the amount of energy use per a staff were considered as input factors. Sales per a staff was considered as output factor. The result shows that most of the public sectors (94.2%) were evaluated as "inefficient" taking into consideration of average value, 0.501 from market-based public corporations, 0.288 from local public corporations, 0.28 from quasi-market-based public corporations, 0.269 from fund-management-based quasi-governmental institutions, 0.09 from non-classified public institutions, and 0.078 from commissioned-service-based quasi-governmental institutions. Furthermore, it is possible to establish a plan for internal Eco-Efficiency improvement based on information of the reference set. In order to improve the Eco-Efficiency in the public sectors in the long term, environmental impacts of the overall public sectors' operations (e.g., energy saving, water saving, waste reduction, and purchasing of green products) needs to be properly proposed in consideration of BSC (Balanced Scorecard) indicators of public sectors.

스마트 항만은 IoT, 빅데이타, AI, 블록체인 등의 디지털 기술을 바탕으로 구축된 항만을 말하며, 항만의 유일한 생존 수단으로서 시·공간 및 자원의 낭비를 최소화하는 항만을 말한다. 지속가능성(Sustainability)이란 '인간이 삶의 터전으로 삼는 환경과 생태계 또는 공공으로 이용하는 자원 따위를 계속해서 사용할 수 있는 환경적 또는 경제, 사회적 특성'을 말하는 것으로 생태계가 환경 파괴 없이 현재의 다양성과 생산성을 미래에도 유지할 수 있도록 하는 '미래 유지가능성'의 의미를 담고 있다. 4차 산업 혁명을 맞이하여 전 세계적으로 스마트 항만 구축과 지속가능성에 대한 관심과 실현이 활발하게 진행되고 있는 상황이다. 본 연구에서는 지속가능한 스마트 항만의 핵심요소인ESG(Enviornment, Social, Governance) 영역의 핵심 지표를 개발하고
