“…In Korea, disaster management and water cycle research were treated as important subjects: damage from wind and water due to climate change accounts for more than 90% of all natural disasters, and it is concentrated in urban areas [ 23 ]. Research on green infrastructure for low-impact development techniques (LIDs) [ 24 , 25 , 26 , 27 , 28 ] in riparian areas, improvement of urban water circulation [ 29 , 30 , 31 ], and reduction in precipitation runoff [ 32 , 33 , 34 , 35 ] was conducted. Research on the preservation and construction of natural capital in Korea was conducted for green growth evaluation techniques [ 36 , 37 ], urban planning and GIS utilization planning techniques [ 38 , 39 ], and volume mapping research on vegetation sites [ 40 ].…”

Government-level ESG (environmental, social, and governance) institutionalization and active ESG activation in the private sector are being discussed for the first time this year in Korea, spurred by increased national interest since the COVID-19 pandemic crisis and the declaration of a carbon-neutral society by 2050, and ESG discussion in many fields is spreading rapidly. In addition, global awareness of the crisis caused by environmental pollution and natural disasters has highlighted the importance of green infrastructure (GI) as a new conceptual alternative to improve public value. Based on sustainability, which is a common goal of ESG and green infrastructure, this study aimed to examine the research targets and techniques of green infrastructure from the perspective of ESG. This study selected and analyzed 98 domestic and international academic journal papers published over the past 10 years in the Web of Science academic journal database literature collection. Focusing on the research subjects, the focus on green infrastructure, and research keywords, we examined the aspects of the green infrastructure plan that have been focused on from the ESG perspective and compared domestic and international research trends. In addition, implications for how each research topic is connected to the concept of ESG according to its function and purpose were derived. By examining the domestic and international research trends of green infrastructure from the ESG perspective, we identified the need for a wider range of research on the diversity and relationship between humans and the ecological environment; policies and systems; and technical research that does not focus only on a specific field. In this regard, we intend to increase the contribution to ESG management in the public sector through the establishment of green infrastructure plans and policies in the future, as they account for a large portion of public capital.

“…The highest LCC and initial cost were observed in CW ($418,324 and $247,059, respectively) while VS had the lowest LCC and initial cost ($210,418 and $42,081, respectively). LCC and initial cost of CW were not so high as compared with the conventional treatment facility and sewage treatment plant (Kloss and Crystal 2006;EPA 2005EPA , 2007Lim et al, 2014). Lim et al, (2014) reported that initial cost of BMP was 10% of the sewage treatment plant' initial cost.…”

Diffuse pollution management in Korea initiated by the Ministry of Environment (MOE) resulted to the construction of pilot facilities termed Best Management Practices (BMPs). Twelve BMPs installed for the diffuse pollution management in the Kyung-An Stream were monitored since 2006. Data on the mass loading, removal efficiency, maintenance activities, etc. were gathered and utilized to conduct the evaluation of long-term performance of BMPs. The financial data such as actual construction, design and maintenance cost were also collected to evaluate the lifecycle cost (LCC) of BMPs. In this study, most of the maintenance activity was focused in the aesthetic maintenance that resulted to the annual maintenance cost of the four BMP types was closely similar ranging from 8,483 $/yr for retention pond to 8,888 $/yr infiltration system. The highest LCC were observed in constructed wetland ($418,324) while vegetated system had the lowest LCC ($210,418). LCC of BMPs was not so high as compared with the conventional treatment facility and sewage treatment plant. On the other hand, the relationship of removal efficiency on unit cost for TSS and TN was significant. This study will be used to design the cost effective BMP for diffuse pollution management and become models for LCC analysis.

“…Brattebo et al (2003) found that the permeable pavement performance in a parking lot located in Renton, Washington was effective in the removal of Cu, Zn, and motor oil over 5 years. Lim et al (2014) reported that the application of LID methods was more cost-effective than sewage treatment plants in Ulsan City. They added that tree box filters, rain barrels, and gutter filters are costeffective in industrial regions.…”

Impervious areas have been expanded by urbanization and the natural structure of water circulation has been destroyed. The limits of centralized management for controlling storm water runoff in urban areas have been suggested. Low impact development (LID) technologies have been promoted as a crucial alternative, establishing a connection with city development plans to build green infrastructures in environmentally friendly cities. Thus, the improvement of water circulation and the control of nonpoint source were simulated through XP-SWMM (storm water and wastewater management model for experts) in this study. The application of multiple LID combination practices with permeable pavements, bioretention cells, and gutter filters were observed as reducing the highest runoff volume by up to 70%. The results from four different LID installation scenarios indicated that permeable paving is the most effective method for reducing storm water runoff. The rate of storm water runoff volume reduced as the rainfall duration extended. Based on the simulation results, each LID facility was designed and constructed in the target area. The LID practices in an urban area enable future studies of the analysis of the criteria, suitable capacity, and cost-efficiency, and proper management methods of various LID techniques.
