  • Underground infrastructure systems provide essential public services and goods through buried structures including water and sewer, gas and petroleum, power and communication pipelines. The majority of existing underground infrastructure systems was installed in green field areas prior to development of complex urban built environments. Currently, there is a global trend to escalate major demand for underground infrastructure system renewal and new installation while minimizing disruption and maintaining functions of existing superstructures. Therefore, Engineers and utility owners are rigorously seeking technologies that minimize environmental, social, and economic impact during the renewal and installation process. Trenchless technologies have proven to be socially less disruptive, more environmentally friendly, energy conservative and economically viable alternative methods. All of those benefits are adequate to enhance overall sustainability. This paper describes effective sustainable solutions using trenchless technologies. Sustainability is assessed by a comparison between conventional open cut and trenchless technology methods. Sustainability analysis is based on a broad perspective combining the three main aspects of sustainability: economic; environmental; and social. Economic includes construction cost, benefit, and social cost analysis. Environmental includes emission estimation and environmental quality impact study. Social includes various social impacts on an urban area. This paper summarizes sustainable trenchless technology solutions and presents a sustainable construction method selection process in a proposed framework to be used in urban underground infrastructure capital improvement projects.

  • The contributions of nuclear science and technology in enhancing prosperity and quality of life all over the world and its potential to achieve many important Sustainable Developments Goals (SDGs) of the United Nations are well recognized. It also is now recognized that with fewer students getting attracted to Science, Technology, Engineering and Mathematics (STEM) in general and nuclear science and technology (NST) in particular; hence, there is a vital need to reach out to young students to provide the crucial human resources needed for these endeavours to continue in this highly specialized area. The success of a recently completed IAEA project related to introducing NST during 2012-2016 in secondary schools in the Asia-Pacific region countries encouraged the formulation of a new IAEA TC project RAS0079 entitled "Educating Secondary Students and Science Teachers on Nuclear Science and Technology" for 2018-2021, focusing on enhancing existing educational approaches through training and development opportunities both for teachers and students. The project aims at reaching a million students during the project duration while keeping the depth of learning between teacher and student. The strategy of executing the project, implementation status and its impact so far is presented in this paper.

  • BACKGROUND/OBJECTIVES: South Korea has been conducting the Sodium Reduction Restaurant Project since 2015 to reduce sodium contents in restaurant menus. The purpose of this study was to analyze changes in the sodium content of menus as determined by the Daegu Sodium Reduction Restaurant Project between 2015 and 2019. MATERIALS/METHODS: Intervention was aimed at reducing the sodium contents of over 10% of menu items in participating restaurants. On-site inspections and evaluations were conducted using a checklist, and reductions in sodium contents were determined by analyzing the salinities and sodium contents of menus after intervention. RESULTS: Post-intervention salinities and sodium contents were significantly lower than baseline values in 2016 (P < 0.001), 2017 (P < 0.001), 2018 (P < 0.001), and 2019 (P < 0.001). However, sodium contents and salinities differences before and after intervention were not significant in 2015. Sodium contents of more than 20% of menu items offered by restaurants that participated in the Sodium Reduction Restaurant Project for 2 yrs starting in 2016 declined by 28.9%. On the other hand, the sodium reduction rate achieved by restaurants that participated for 4 yrs from 2015 reached 55.4%. The percentage of restaurants that participated in the project increased annually, though some failed to be designated as Sodium Reduction Restaurants because they did not meet sodium reduction rate requirements. CONCLUSIONS: Positive correlations were found between duration of participation in the project and sodium reduction and designation rates. Sustainable long-term support at the national level is required to expand the project to other regions.

  • The U.S. Department of Energy conducts the Solar Decathlon competition as a student-based achievement that encourages sustainable design with energy efficiency and solar energy technologies. In the 2020 competition, the University of Nevada, Las Vegas (UNLV) team designed, fabricated, and constructed a net-zero modular house that applies innovative and highly efficient building technologies. This paper focused on the lessons learned during the early phases of this ongoing modular project. The research methodology included obtaining feedback from key project participants using a well-structured questionnaire. The results showed that the major items/challenges in the project's planning phase included selecting the modular size, planning the construction system, planning the materials and procurement, estimating costs and duration, selecting a fabricator, collaboration and communication, safety, and planning module transportation. These findings will help modular practitioners and future Solar Decathlon competition participants better understand how and what factors they should consider most during the early phases through the lessons learned.

  • The Equator Principles are a set of voluntary environmental and social guidelines for ethical project finance. These principles commit banks and other signatories to not finance projects that fail to meet these guidelines. The principles were conceived in 2002 on an initiative of the International Finance Corporation and launched in 2003. Since then, dozens of major banks have adopted the Principles, and with these banks among them accounting for more than three quarters of all project loan market volume the Principles have become the de facto standard for all banks and investors on how to deal with potential social and environmental effects of projects to be financed. While regarding the Principles an important initiative, NGOs have criticised the Principles for not producing real changes in financing activities and for allowing projects to go through that should have been screened out by the Principles, such as the Sakhalin-II oil and gas project in Russia. In early 2006, a process of revision of the principles was begun. The Equator Principles state that endorsing banks will only provide loans directly to projects under the following circumstances: - The risk of the project is categorized in accordance with internal guidelines based upon the environmental and social screening criteria of the International Finance Corporation (IFC). - For all medium or high risk projects (Category A and B projects), sponsors complete an Environmental Assessment, the preparation of which must meet certain requirements and satisfactorily address key environmental and social issues. - The Environmental Assessment report addresses baseline environmental and social conditions, requirements under host country laws and regulations, applicable international treaties and agreements, sustainable development and use of renewable natural resources, protection of human health, cultural properties, and biodiversity, including endangered species and sensitive ecosystems, use of dangerous substances, major hazards, occupational health and safety, fire prevention and life safety, socio-economic impacts, land acquisition and land use, involuntary resettlement, impacts on indigenous peoples and communities, cumulative impacts of existing projects, the proposed project, and anticipated future projects, participation of affected parties in the design, review and implementation of the project, consideration of feasible environmentally and socially preferable alternatives, efficient production, delivery and use of energy, pollution prevention and waste minimization, pollution controls (liquid effluents and air emissions) and solid and chemical waste management. - Based on the Environmental Assessment, Equator banks then make agreements with their clients on how they mitigate, monitor and manage those risks through an 'Environmental Management Plan'. Compliance with the plan is required in the covenant. If the borrower doesn't comply with the agreed terms, the bank will take corrective action, which if unsuccessful, could ultimately result in the bank canceling the loan and demanding immediate repayment. - For risky projects, the borrower consults with stakeholders (NGO's and project affected groups) and provides them with information on the risks of the project. - If necessary, an expert is consulted. The Principles only apply to projects over 50 million US dollars, which, according to the Equator Principles website, represent 97% of the total market. In early 2006, the financial institutions behind the Principles launched stakeholder consultations and negotiations aimed at revising the principles. The draft revised principles were met with criticism from NGO stakeholders, who in a joint position paper argued that the draft fails by ignoring the most serious critiques of the principles: a lack of consistent and rigorous implementation.

  • This study aims to survey whether local governments have legislated laws and regulations on environment impact assessment system, to compare and analyze specific projects and their scale, assessment items, and procedures & discussion process, to identify issues and generate improvement plans, and to suggest a direction for future legislation to local governments that plan to legislate laws and regulations in the future. Major outcome of the study are as follows. First, terminologies used for environment impact assessment by local governments need to be unified. Also, laws and regulations need to be legislated soon. Second, in "urban development project" areas, a total of nine project areas including "quarrying of soil and stone, sand, gravel, and minerals" was essential common projects. A total of six project types were added or newly established compared to national systems. Among them, four project types were added within national-level project areas and two project types were not available under the national-level project areas and newly added due to the nature of local governments. Third, in terms of project scale, scale enhancement of "urban development project" was most common. Analysis showed that in case of clean natural environment such as Cheju Island, it is necessary to consider reinforcing project areas where development activities take place directly in forests or rivers such as "industrial base and complex development", "water resource development", and "development of tourism complex." Fourth, the discussion and review procedures of assessment reports were similar to those at government level. However, in case of Seoul city, it is required to write a "preparation plan" before drafting an assessment report. The city features partial introduction of scoping and screening, which allows to exempt discussion procedures if impact on environment is found to be minimal after drafting the assessment report. In case of national-level, it has a dual system that is split between Ministry of Construction and Transportation and Ministry of Environment. However, in case of environment impact assessment of local governments, it is a single system where city mayors and provincial governors are in charge of both project execution and environmental assessment. Therefore, the most important task is how to satisfy objectiveness and accountability.

  • This study is based on the design project of 'Sun-Garden' within the Solaseado Solar Power Plant located in Solaseado, which is a New City being developed in Haenam, Jeollanam-do. The purpose of this study is to create an integrated and sustainable energyscape that harmonizes energy infrastructure with the natural environment, while supporting the city's carbon neutrality agenda. To achieve this, design principles were established by considering three key aspects. The first aspect is economic, which seeks to create multifunctional spaces that integrate nature and technology, pursuing long-term sustainability while generating additional economic value. The second aspect is natural, emphasizing the creation of planting environments that conserve and enhance ecosystems, introduce region-specific species, and maintain ecosystem services and sustainable resource use. The third aspect is landscape, offering sensory and educational experiences to visitors and functioning as a landmark that symbolizes the carbon-neutral garden city of Solaseado through the aesthetic harmony of nature and technology. Through the creation of the 'Sun-Garden,' the Solaseado Solar Power Plant exemplifies a sustainable energyscape development model that merges economic, environmental, and landscape aspects beyond the conventional energy production facility. This project is expected to provide guidelines and implications for future energy infrastructure design, contributing to global energy transition efforts.
