We estimated the potential area roof greening in Gyeonggi-do that will mitigate the heat island effect. The estimation was based on building age, roof shape, and building use which were recorded in the building register from "Sewoomteo, the Building Administration System in the Ministry of Land, Transport and Maritime Affairs. The estimated potential roof greening area in Gyeonggi-do was approximately $102.5km^2$ assuming that the buildings for residence, public, education(school), office, shopping mall are appropriate for roof greening. The area occupied by apartment buildings over six-story was 76.3% of the potential roof greening area 10.2% for individual houses, 5.9% for under five-story apartment buildings, and 3.7% for school buildings. The result indicated that it is residential buildings that we need to pay attention for roof greening, especially high-rise buildings over six-story. Greening of the whole estimated area, $102.5km^2$, in Gyeonggi-do will result in the increase of green space per capita by $8.74m^2$. This is 1.65 times greater than the area of current urban parks, and 1.97 times greater than the total area of neighborhood parks, children's parks, and pocket parks. Greening of the estimated roof area will increase green coverage of urban area by twice, adding to current green coverage of the urban areas, 11.3%, in 10 major cities. In particular, the effect of roof greening would be remarkable in inceasing the green space of Anyang City, Gwangmyeong City, and Guri City where neighborhood park area falls short.

This study relates to measure impact of green technology on industry sector by uses of industry greening indices. For this study, we performed patent trend analysis, technology-industry concordance analysis, and designed some industry greening indices. Through the results of this research, we found out the impact of Korean high priority green technologies on respective industries, and consequently identified which industries play an important role in the era of green innovation. IT related industries would catch somewhat weak attention in green technology policy, though they manufacture and use plenty of patents at present. Meanwhile, Energy related industry, such as battery industry would catch strong attention in green innovation, showed very high value of industry greening indices. In order to design proper R&D strategy for green technologies, understanding industry and market structure that can adapt and promote green technology innovation is important. In this context, this study could be an effective and systematic tool for assisting green innovation policy. Also, these indices developed are not limited to the case of green technology, other technologies can be used universally as a input for analysis.

In high-density urban areas, the urban heat island effect increases urban temperatures, leading to negative impacts such as worsened air pollution, increased cooling energy consumption, and increased greenhouse gas emissions. In urban environments where it is difficult to secure additional green spaces, rooftop greening is an efficient greenhouse gas reduction strategy. In this study, we not only analyzed the current status of the urban heat island effect but also utilized high-resolution satellite data and spatial information to estimate the available rooftop greening area within the study area. We evaluated the mitigation effect of the urban heat island phenomenon and carbon sequestration capacity through temperature predictions resulting from rooftop greening. To achieve this, we utilized WorldView-2 satellite data to classify land cover in the urban heat island areas of Busan city. We developed a prediction model for temperature changes before and after rooftop greening using machine learning techniques. To assess the degree of urban heat island mitigation due to changes in rooftop greening areas, we constructed a temperature change prediction model with temperature as the dependent variable using the random forest technique. In this process, we built a multiple regression model to derive high-resolution land surface temperatures for training data using Google Earth Engine, combining Landsat-8 and Sentinel-2 satellite data. Additionally, we evaluated carbon sequestration based on rooftop greening areas using a carbon absorption capacity per plant. The results of this study suggest that the developed satellite-based urban heat island assessment and temperature change prediction technology using Random Forest models can be applied to urban heat island-vulnerable areas with potential for expansion.

The significance and means of parks and green space planning have been changed dramatically in this century in Japan. The first priority must be given to define the means and purposes of planning., especially the role of ecological, social and economical management with the increasing trend of environmental concern, and the method to estimate values of park and green space from the point of view of regenerative society development. The role of planning parks and green space is reviewed in the following three aspects; as tools for land use control (master plan), as tools for finding appropriate lands for purchasing land (development plan) and tools for application of individual development technique of green space and landscapes(site plan and design). It is a serious issue that the existence of parks in urban setting which used to be considered as a top priority, is now being challenged in terms of economical, social and environmental benefits. In such processes, the most important issue is to define what makes parks and green spaces attractive and ecological to obtain social support to be developed.

Urban problems are constantly occurring around the world due to rapid industrialization and population decline. In particular, as the number of vacant houses is gradually increasing as the population decreases, it is necessary to prepare countermeasures. A plan to utilize vacant houses has emerged to restore the natural environment of the urban ecosystem where forest destruction, damage to habitats of wild animals and plants, and disconnection have occurred due to large-scale development. Through connectivity analysis, it is possible to understand the overall ecosystem flow based on the movement of species and predict the effect when vacant houses are converted into green spaces. Therefore, this study analyzed the green area network to confirm the possibility of greening of vacant houses neglected in Jeonju based on circuit theory. Using Circuitscape and Least-cost path, we tried to identify the connectivity of green areas and propose an ecological axis based on the analysis. In order to apply the resistance values required for analysis based on previous studies, the 2020 subdivision land cover data were integrated into the major classification evaluation items. When the eight forests in the target site were analyzed as the standard, the overall connectivity and connectivity between forests in the area were high, so it is judged that the existing green areas can perform various functions, such as species movement and provision of habitats. Based on the results of the connectivity analysis, the importance of vacant houses was calculated and the top 20 vacant houses were identified, and it was confirmed that the higher the ranking, the more positive the degree of landscape connectivity was when converted to green areas. In addition, it was confirmed that the results of analyzing the least-cost path based on the resistance values such as connectivity analysis and the existing conceptual map showed some differences when comparing the ecological axes in the form. As a result of checking the vacant houses corresponding to the relevant axis based on the width standards of the main and sub-green areas, a total of 30 vacant houses were included in the 200m width and 6 vacant houses in the 80m width. It is judged that the conversion of vacant houses to green space can contribute to biodiversity conservation as well as connectivity between habitats of species as it is coupled with improved green space connectivity. In addition, it is expected to help solve the problem of vacant houses in the future by showing the possibility of using vacant houses.

The government of the UK since the 1990, especially under the new Labour Party, has pursued sustainable development or carbon control as a core strategy for its national development. The seemingly prominent environmental policy for 'greening the government' of the UK as well as considerable achievements in energy and environment indices have attracted much attentions of policy makers and researchers for the 'low carbon green growth' in Korea. This paper tries to see the character of carbon control and environmental policy in the UK not merely as the integrating or mainstreaming policy but a new strategy for national development, that is, for the 'ecologically modernized' state, eco-state, or green state. It defines the environmental policy for carbon control in the UK as the strategy for the green state which has provided it as a principal guide for integrating national policies as a whole, and which has pursued it through market-dependent neoliberal measures. From this point of view, this paper introduces the development process of carbon control and environmental policy mainly under the new Labour Party government in the UK, and gives a reappraisal of both its policy and of energy-environment indices.

The purpose of this study is to propose a way to develop and disseminate the renewable energy technologies and industries in the local community. Fundamentally, the renewable energy is able to reduce environmental pollution and diminish a use of fossil-fuel energy in the local area. And it will lead to promoting regional sustainable energy in the future, as well as making contributions to local economic development. Above all, based on the environmental conservation project, including greening of the city and improving water quality, Daegu metropolitan city has launched a series of renewable energy projects, such as solar city programs and local energy plan. But, some problems still exist, due to the technological, economic and socio-political barriers. Thus, to encourage and disseminate a renewable energy in Daegu city, we need to examine a present condition on renewable energy and analyze constraint elements to prevent its distribution. Based on the results, we have to set the feasible strategy to develop and disseminate renewable energy in Daegu city and help it systematically integrate renewable energy technologies and industries into environmental economics and city planning. Ultimately, to achieve this purpose, we need to adopt the following policy measures: (1) establishment of a master plan for renewable energy; (2) interconnection between local development project and energy industry; (3) promotion of technological development; (4) inducement of and assistance to renewable energy industry; (5) fostering venture companies; (6) specializing Daegu's public office by energy-specific education programs. In particular, local entities including local company, consumers, policy-makers and citizen's groups have to pay attention to local energy plan for the regional sustainable energy future. These measures will lead to establishing an environmentally friendly and sustainable city.
