Hydrogen as an environmentally friendly energy carrier has received special attention to solving uncertainty about the presence of renewable energy and its dependence on time and weather conditions. This material can be prepared from different sources and in various ways. In previous studies, fossil fuels have been used in hydrogen production, but due to several limitations, especially the limitation of the access to this material in the not-too-distant future and the great problem of greenhouse gas emissions during hydrogen production methods. New methods based on renewable and green energy sources as energy drivers of hydrogen production have been considered. In these methods, water or biomass materials are used as the raw material for hydrogen production. In this article, after a brief review of different hydrogen production methods concerning the required raw material, these methods are examined and ranked from different aspects of economic, social, environmental, and energy and exergy analysis sustainability. In the following, the current position of hydrogen production is discussed. Finally, according to the introduced methods, their advantages, and disadvantages, solar electrolysis as a method of hydrogen production on a small scale and hydrogen production by thermochemical method on a large scale are introduced as the preferred methods.

Purpose - The purpose of this study is to investigate the effect of macroeconomic conditions on the relationship between CSR and firm value. Design/methodology/approach - Employing KEJI index as a proxy for a firm's CSR activities, we investigate whether investors discount the value of CSR activity during the economic recession when a firm's bankruptcy risk is high and thus its future sustainability is suspected. Findings - Our empirical result represents that the value of a firm with high CSR score is undervalued during recession, reflecting investors doubt the sustainability of a firm whose CSR score is high when overall economy is exposed to high downside risk. Research implications or Originality - It implies that investors may not regard the CSR activities as an indicator of corporate sustainability. Also, the result represents that stable macroeconomic condition can be one of the important factors to make the CSR activity increase a firm's value.

The purpose of this study is to raise the necessity of ensuring sustainability of water infrastructures in economic, social and environmental sectors by using index that evaluates the sustainability centering on water supply and wastewater utilities. This study identified sub-indexes that should be stressed among different indexes in economic, social and environmental aspects and those indexes were compared by each clusters of cities. The principal component analysis was used to calculate the weights of the sub-indexes, and the k-mean cluster analysis was conducted to classify the clusters. As a result of the weighting analysis, financial independence, service revenue ratio, subsidy ratio, population coverage ratio, deterioration, stream/river ecosystem health and river water quality were found to be the major variables in assessing sustainability. Cities were then classified into two groups using the k-mean cluster analysis. The overall sustainability scored high in the economic sector was relatively satisfactory, but it was necessary to improve the environmental sustainability. The group with relatively good environmental sustainability showed low score in the overall sustainability and required improvements in the economic sector.

To assess the water resources sustainability, many indicators and methodologies have been suggested by international organizations and developed in other countries. However, in the previous studies, some of indicators were unsuitable for assessing the sustainability of water use and management in Korea. Thus, in this study nSl(Water Resources Sustainability Index), a multi-variable index, was created by consideration of environmental, social, and economical criteria. Relative weights for components, indicators and sub-indexes, were determined by employing the Analytic Hierarchy Process. In order to extract the indicators related with water resources sustainability, the data related with water resources and indicators suggested in various field were compared and thoroughly reviewed. These indicators were classified into four groups; Economic Efficiency Index, Social Equity Index, Environmental Conservation Index, and Maintenance Capability Index. The weight of each component were decided by the survey of 127 specialists in water resources and sustainability. The result of survey represented that efficiency and equity of water use and water quality for river restoration are major issues in enhancing the water resources sustainability In addition, it was found that investment and public participation should be considered for sustainable water use.

Social enterprise has moved from periphery to take center stage. Social enterprises are a truly global phenomenon and associated with solving social problems with business approaches. While the numbers of social enterprises have grown and their impact is likely to continue to do so, it would be dangerous to assume that the revolutionary momentum will automatically continue, because social enterprise faced sustainability challenges. This study collected the data from directory of Korean Social Enterprise to conduct a quantitative research on the growth of social enterprise in South Korea. This study conducted longitudinal analysis of 491 social enterprise certified between 2007 and 2010, of economic performance with financial index and social impact with employment structure. Though global financial crisis, Korean social enterprises show that there is a considerable increase in all of quantitative and qualitative aspects. Korean social enterprises have provided meaningful work to those normally excluded from the labour market and tried to raise their life of working. In the future, Korean social enterprises should find a way to balance social and financial performance and ensure the sustainability of the business.
