The objective of this paper is to investigate the impact of economic growth (per capita real GDP), the square of per capita real GDP, energy use, financial development (FD), and foreign direct investment (FDI) on ecological footprint (EF) in the case of Malaysia over the period 1971-2014, by employing the ARDL approach. The long-run results revealed that economic growth has a significant positive impact on the ecological footprint and it implies that the economic growth deteriorates the environmental quality in Malaysia. Conversely, the square of GDP showed a negative and significant impact on the EF in the long run. As the coefficient of GDP in our study is positive and statistically significant while the coefficient of squared GDP is negatively significant, thus, this study supports the presence of the environmental Kuznets curve (EKC) hypothesis in the case of Malaysia. Furthermore, the result indicates that FDI has a positive and significant impact on the EF in the long run, which means a rise in FDI will enhance the environmental pollution level. Thus, it confirms the pollution haven hypothesis. Hence, it suggests that Malaysia imposes stricter environmental policies. Further, FDI and FD are causing GDP in Malaysia, but through increasing EF.

The purpose of this study is to analyze the effect that consumption patterns of human affect the ecosystem using analysis of ecological footprint(EF) and assessment of ecosystem service value in Daegu Metropolitan Area. The data for analysis were constructed from statistical yearbook of each city and average of public land price on land category. According to the EF analysis on city, total EF of Goryeong was showed the highest by 3.3052gha in 2007. However, total EF of Daegu was assessed the lowest by 2.0134gha among 8 cities. In the results of ecological deficit, 7 cities except Gunwi were assessed by condition of ecological deficit and had exceeded environmental capacity until 2007. Specially, it was analyzed that Daegu may need additional area more than about 30 times to maintain the present consumption patterns. On the one side, the results of analysis of ecosystem service value in Daegu were assessed that citizens of Daegu have borrowed about 1,078.6 million wons to ecosystem per year and one person.

The purpose of this study was to analyze middle school students' consumption lifestyle and develop a program for measuring Ecological Footprint (EF) for them. For this study, 200 male and female middle school students in large cities, medium & small cities were selected to analyze their consumption lifestyle. It was also that the existing programs for measuring EF were studied and basic rules of setting up new EF indicators were established based on the results of survey and literature study. 15 indexes was selected by dividing the life areas into food, housing, traffic, goods and services areas and than the delpi computer programming tools was used to develop program for measuring EF in this study. The program for measuring EF can be used as educational materials for consumers' environment education in the areas of social environment education and school environment education. The followings are suggestions coming out of this study. First, it is required to revise and complement program for measuring EF analyzing the problems that occur when applying it to middle school students actually. Second, some data that used during normalization of EF ate originally from the USA. So it is necessary to change the data to meet the Korean situation. Third, it is necessary to have design work that can invite interests of students with consumers' environmental education materials through cooperation between environmental education experts and computer programmers. Fourth, it is necessary to have practical research with consumers' environmental education adding educational contents into EF measurement program. Fifth, it is necessary to develop a method for distribution an expansion of the program for measuring EF to make it usable in different types of environmental education materials.

Achieving sustainable development requires an increasing share of green technologies. World energy demand is expected to rise significantly especially in developing economies. The increasing energy demands will be entertained with conventional energy sources at the cost of higher emissions unless eco-friendly technologies are used. This study examines the asymmetric effects of nuclear energy on carbon emissions for Pakistan from 1974 to 2019. Augmented Dickey-Fuller (ADF) and Phillips Perron (PP) unit root tests suggest that variables are integrated of order one and bound test of Autoregressive Distributed Lag (ARDL) and nonlinear ARDL confirm a long-run relationship among selected variables. The ARDL, Fully Modified Ordinary Least Squares (FMOLS), and Dynamic Ordinary Least Squares (DOLS) results show that the coefficient of nuclear energy has a negative and significant impact on emissions in both short and long run. Further, the NARDL finding shows that there exists an asymmetric long-run association between nuclear energy and CO₂ emissions. The vector error correction method (VECM) results indicate that there exists a bidirectional causal relationship between nuclear energy and carbon emissions in both the short and long run. Additionally, the impact of nuclear energy on ecological footprint has been examined and our findings remain robust.

Environmental capacity assessment of Busan city was conducted to provide basis for planning on sustainable development and growth of the city. Using Onish model, assessment was carried out on amenities and service facilities for the citizens of Busan city. Ecological Footprint model was used to judge if the city exceeds the its environmental capacity and to estimate the extent of the excess if it exists. The analysis using Onish model revealed that the citizens of Busan city are generally well supported by the infrastructure and service facilities of the city. Water treatment and supply facilities have enough capabilities to support the city, whereas the relatively low rate of sanitary sewer supply (78%) suggests the need for further improvement in the wastewater area. The capacities of sanitary landfills are found sufficient enough to support the city for the next 10 years. The high value for the line length served per capita in the subway sector hints on certain inconvenience of commuters. All the air quality indicators meet the Korean and WHO standards except for $NO_2$. The ecological footprint model analysis produced EF indicators for Busan city of 3.04 ha/person and 2.54 ha/person for the years of 1993 and 2003, respectively. The decrease of the indicator from 1993 to 2003 is mainly due to the incorporation of Gijang area by Busan city in 1995, suggesting the importance of the ecologically productive area in the evaluation using this model. The analysis on the ecological deficit that is based on ecologically productive land shows that the consumption by Busan city exceeds its ecologically available production by 19,600% as of 2003. The area needed to support the consumption of Busan city in 2003 is 123 times as large as the present area of Busan city, which is substantially lower than the multiplier (742) obtained for Seoul city in 1997 but is higher than those observed for Chongju city (71 in 1999) and Ulsan city (39 in 2001).

가상수의 흐름을 보다 가시적으로 파악하기 위하여 대두된 개념이 물발자국(water footprint)이다. 이는 흔히 사용되고 있는 생태발자국(ecological footprint)이나 탄소발자국(carbon footprint)에 착안하여 도입된 개념으로 한 국가의 물발자국은 직 간접적으로 물건이나 재화를 생산하는데 국민이 소비하는 물의 총량으로 정의된다. 물발자국을 내적/외적으로 단순히 구분하여 산정하는 방식이 진화하여 1단위의 생산에서 유통 및 서비스까지 확대하여 그 전 과정을 모두 포함하는 물발자국 산정방식이 도입된 것은 최근의 일이다. 직접적인 물사용과 간접적인 물사용을 구분하여 물발자국을 산정하고, 그 위에 물의 성질에 따라 green water, blue water, 그리고 grey water로 각각 개념을 상세화하여 물발자국을 산정하는 방안이 도입되었다. 2009년 물발자국 산정의 표준화를 위한 스위스의 제안이 ISO에 제출되었고, 각 국가들에 의한 투표가 진행되어 2010년 물발자국 국제표준안이 채택되었다. 본 연구는 이러한 국제기구에 의한 일련의 국제표준화 작업을 대상으로 진행되었다. 2014년 ISO/TC 207 국제총회가 개최되어 환경경영시스템(SC1), 환경감사(SC2), 환경 라벨링(SC3), 환경성과평가(SC4), 전과정평가(SC5), 온실가스관리(SC7)의 6개 분과위원회(Sub-Committees)가 구성되어 세부논의가 진행되었으며, 이러한 과정을 분석함으로서 물발자국 국제표준(ISO 14046)과 향후 우리나라의 대응방안을 고찰하였다. 물발자국 국제표준(ISO 14046) 제정을 통해 물발자국의 필요성 및 중요성에 대한 국가 간 합의는 도출되었으나, 적용시기 및 세부적인 방법론 등에 대한 이견이 여전히 존재하고 있다. ISO 14046의 실질적 적용에 필요한 세부사항과 관련된 기술보고서 작업초안(WD 14073)은 작업반(SC5/WG8)에서 진행되고 있다. 그러나 물발자국 국제표준이 국가 간 무역장벽이나 특정국의 진입을 막는 수단으로 사용될 수 있는 점 등 실질적으로 국제표준의 도입에 따른 문제점 역시 존재한다. 본 연구에서 제시된 국제표준의 도입 방안을 통하여 가상수무역의 국제적 선점효과를 기대함과 동시에 수자원의 유효한 활용을 기대할 수 있을 것이다.

World population has increased rapidly following the industrial revolution, reaching 7 billion in 2012. Several forecasts estimate that this number will rise to about 8 billion in 2025. Improvements of living standards in developing nations have also raised resource and energy demands worldwide. In consequences, human beings have faced many global and urgent problems, such as global warming, water and food shortages, resource and energy crises, and so on. Many ocean utilization technologies for avoiding or reducing such big problems have been developed, for examples $CO_2$ ocean sequestration, seawater desalination, artificial upwelling, deepwater mining, and ocean energies. It is important, however, to assess such technologies from the viewpoints of sustainability and public acceptancy, since the aims of those technologies are to develop sustainable social systems rather than conventional ones based on fossil resources. Inclusive Marine Pressure Assessment and Classification Technology Research Committee (generally called IMPACT Research Committee) of Japan Society of Naval Architects and Ocean Engineers, has proposed Inclusive Impact Index "Triple I" as an indicator, which can predict both environmental sustainability and economical feasibility, in order to assess the ocean utilization technologies from the viewpoints of sustainability and public acceptancy. This index was considered by combining Ecological Footprint and Environmental Risk Assessment. The Ecological Footprint and the Environmental Risk Assessment are introduced in the first part of this paper. Then the concept and the structure of the Triple I are explained in the second part of this paper. Finally, the economy-ecology conversion factor in Triple I accounting is considered.

North Korea has been in ecologically deficit state since 1966, despite of lack of energy and food resources. Trends of the Biocapacity (BC), the Ecological Footprint (EF), and the Ecological Deficit (ED) of North Korea were shown and five factors influencing on the Overshoot Rate (OSR) which is the ratio of the BC and the EF in North Korea was analyzed in this study. The five factors consist of two factors affecting to the EF and three factors affecting to the BC in North Korea. Two of the five factors are affecting to the EF those are population, the EF per capita (EFPC) which indicates the individual environmental consumption intensity, and three are affecting to the BC those are the land area, the yield factor, and the value multiplying the equivalence factor and the intertemporal yield factor. The EF has contributed more than the BC to the OSR. From 1966 to mid-1990s, the EFPC was the most contributing factor at about 60%, and after mid-1990s, population at about 40~60%. Contribution ratio of land area and the yield factor have increased after mid-1990s up to 15% and 18%, respectively. The BC of cropland which has decreased due to a decrease in productivity. In order to reduce the ED of North Korea, improvement of productivity of cropland and restoration of forest. Forest area has decreased significantly since 1990 in NK. And ways to solve the food shortage problem which influences on decrease of both productivity of cropland and forest area.
