This paper presents a summary and review of life cycle sustainability assessment (LCSA) methods for the transport sector. The paper provides a comprehensive overview of articles that employ a variety of methods for assessing sustainable development in the transport sector, taking into account the economic, social, and environmental dimensions. In the sustainability assessment of transport, three methods were evaluated: life cycle assessment (LCA), life cycle cost analysis (LCC), and social life cycle assessment (SLCA). An overview of sustainability assessment methods in transport and a review of the indicators used in the life cycle sustainability assessment was conducted. It was found that the selection of indicators within the LCSA for assessing various aspects of sustainable development is dependent on various geographic and policy contexts. An overview of the application of multi-criteria decision analysis (MCDA) methods to assess LCSA in the transport sector was performed. MCDA methods are used to support decision-making regarding the selection of the most sustainable transport options and allow for the simultaneous consideration of multiple criteria, enabling a more sustainable assessment of different transport options. MCDA methods help to rank alternative transportation fuels and help decision-makers consider indicators encompassing economic, environmental and social aspects.

This study evaluates the characteristics of geopolymer masonry mortars (GMMs) made with slag–fly ash binder and up to 100% recycled fine aggregates (RFAs). For each RFA replacement rate, two types of GMMs, namely N and S types based on ASTM C91, were proportioned and tested for mechanical, physical, and durability properties. Results revealed that using geopolymeric binder enhanced the flow, water retention, compressive strength, sorptivity, and abrasion resistance of GMMs compared to cementitious counterparts but reduced the initial setting time by up to 75%. Subsequent RFA additions negatively affected the flow, setting time, density, water absorption, porosity, and bulk resistivity but enhanced the water retention, sorptivity, and abrasion resistance of GMM. It also reduced the compressive, pull-off, and flexural strengths by 36, 44, and 27%, respectively. Furthermore, S-type mortars exhibited improved bulk resistivity, sorptivity, and abrasion resistance compared to N-type counterparts. A multifunctional performance index deduced that the GMM mixes incorporating 100% RFAs were superior to geopolymeric or cementitious masonry mortars made with natural fine aggregates (NFAs). Such findings emphasize the sustainability of GMMs made with RFAs in masonry construction, eliminating the need for water curing while maintaining comparable or even superior properties compared to cement-based mortars made with NFAs.

Economic globalisation has accelerated the cross-regional flow of resource elements and broken through the constraints of traditional regional administrative boundaries. Urban agglomerations are core carriers that drive and accelerate regional integration development and can promote the division of urban functions and cooperation. This study considers the Nanjing metropolitan area as a case study to construct a comprehensive first-degree evaluation index system for cities from a factor-flow perspective, focusing on economic, cultural, and transportation connections. We found that (1) Nanjing, which has long been ranked first, shows a downward trending score, dropping from 0.956 in 2017 to 0.937 in 2023; (2) The comprehensive first-degree spatial structure of metropolitan-area cities presents a network hierarchical development feature of “one core, multiple centres, and multiple areas”. With Nanjing as the regional core city, Chuzhou (0.879), Yangzhou (0.915), and Wuhu (0.897) as sub-centre cities, and other cities as sub-regional nodes, the urban system structure gradually forms; (3) The indicators of economic (0.166 **), cultural (0.226 **), and transportation (0.644 ***) element connections were interrelated and mutually reinforced, forming a unified entity with internal connections. This study quantitatively measured the level of integrated development in the Nanjing metropolitan area and provided a reference for formulating regional policies.

This discussion describes an experimental behavioral economics class implemented in a service learning format. Students implemented two nudge interventions to influence public trash behavior, which is an issue throughout the Middle East/North Africa (MENA). The aim in one project was to encourage more use of trash bins in a multi-screen theater and in the other to sort plastic, glass, and paper when throwing trash in the public bins at a university. These two organizations paid the implementation costs, which were quite low, as common for most nudges. The class was co-taught by two university faculty and several personnel from governmental and UN offices responsible for building nudge capabilities in Kuwait. In each case, results in the student projects demonstrated that nudging resulted in a substantial improvement. Students gained strong competencies in applying sustainability principles to a specific problem and in carrying out a real-world project. They learned the importance of collaborating with stakeholders and got to see that their work was actually used in policy formation by the Kuwait government and the UNDP’s Kuwait office.

Several studies have assessed the thermal performance of green and cool roofs. However, few have comprehensively addressed Brazilian buildings and climates, considering indoor and outdoor environments. Considering three Brazilian cities, this study aims to assess the performance of green and cool roofs compared with traditional fibre cement roofs in a typical multifamily residential building. Energy consumption, thermal comfort, and outside surface temperature were assessed using computer simulation. The results show that the cool roofs performed better in cities with warmer climates (e.g., Cfa and Aw), reducing electricity consumption by up to 24.8% compared with traditional roofs. Green roofs are better suited for colder climates (e.g., Cfb), with up to 28.2% energy savings. Green roofs provided the highest percentage of thermal comfort hours in all climates. Cool and green roofs provided hourly reductions in outside roof surface temperature of up to 16.5 °C and 28.4 °C, respectively, compared with the traditional roof. This work reinforces that the choice between these two roof types for each city depends on the parameter used for comparison. Based on the relevant information applied to Brazilian buildings and representative climates presented, this work provided recommendations for urban planning policies and building regulations in Brazil.

In the Philippines, where agriculture plays a vital role in the economy, nearly half of the country’s 30 million hectares of land is used for agricultural purposes. Despite government efforts to support rice farmers, challenges, such as production failures and profit losses, remain prevalent. This study evaluates the quality of government services provided to rice farmers through a service quality-based framework (SERVQUAL), assessing five key dimensions: assurance (AS), empathy (EM), reliability (RL), responsiveness (RS), and tangibility (TA). Structural equation modeling (SEM) is employed to examine the relationships among these service quality dimensions and other latent variables, including service quality (SQ), farmers’ satisfaction (FS), farmers’ trust (FT), perceived security (PS), and perceived effectiveness (PE). Data were gathered from 400 respondents using a 55-item survey. The findings indicate that perceived security (PS) is the most critical factor in enhancing the overall quality of government services. The study emphasizes the importance of adopting a SERVQUAL-based approach, with a focus on reliability and responsiveness to improve farmers’ satisfaction and trust. Additionally, fostering trust between farmers and the government is crucial to increasing the effectiveness of government programs and strengthening farmer–government collaboration. The study further advocates for prioritizing sustainable agricultural practices to ensure long-term productivity and environmental resilience. By improving service quality with a focus on sustainability, the Philippines can work towards achieving broader sustainable development goals.

The morphogenetic diversity of an area often determines its high geodiversity, which is subsequently used for geotourism. Areas where geotourism is being intentionally developed note the funded impacts resulting from increased interest in the area by tourists. This paper presents a morphogenetically diverse area that has been formed by glacial activity, cosmic factors—meteorite impacts, fluvial factors and anthropogenic factors—especially those related to industrial activities and settlement processes. In this manuscript, we identified and assessed geosites in the diverse landscape of the Poznań region (Poland), as well as analyzed strengths, weaknesses, opportunities and threats in relation to possible activities aimed at the development of geotourism. The multi-criteria assessment of existing and proposed geosites and SWOT analysis was used by us to assess geotourism development potential in this genetically highly diverse landscape. The work presented here demonstrates that not all formally created geosites by geological institutions are potentially attractive from the point of view of geotourism. The main factors that reduce the attractiveness of geosites are the lack of recreational infrastructure, poor accessibility and low educational values. The spectacularity of geosites is most often determined by their aesthetic value, representativeness, rareness and paleogeographical interest. The Poznań region has a high potential for the development of geotourism due to its valuable sites (Morasko Meteorite Reserve, Dziewicza Hill, post-mining area Szachty, Genius Loci and Ostrów Tumski); however, there is a need to develop a geotourism development strategy in the area. Given the morphogenetic diversity of the study area, there is a need to create a unique landscape geointerpretation center in this part of Europe, with a role in integrating tourism and especially geotourism activities.
一个地区的形态多样性往往决定了其高度的地质多样性，随后被用于地质旅游。正在有意开发地质旅游的地区注意到，游客对该地区兴趣的增加带来了资金方面的影响。本文介绍了一个由冰川活动、宇宙因素（陨石撞击）、河流因素和人为因素（特别是与工业活动和定居过程有关的因素）形成的形态多样的地区。在本手稿中，我们对波兹南地区（波兰）多样地貌中的地质景观进行了识别和评估，并分析了与可能开展的地质旅游活动相关的优势、劣势、机遇和威胁。我们对现有和拟议的地质景观进行了多标准评估，并采用 SWOT 分析方法来评估这一基因高度多样化景观的地质旅游发展潜力。本文介绍的工作表明，从地质旅游的角度来看，并非所有由地质机构正式创建的地貌景观都具有潜在的吸引力。降低地貌景观吸引力的主要因素是缺乏娱乐基础设施、交通不便和教育价值低。地貌景观的壮观程度通常取决于其美学价值、代表性、稀有性和古地理学意义。波兹南地区因其宝贵的景点（莫拉斯科陨石保护区、Dziewicza 山、Szachty 后矿区、Genius Loci 和 Ostrów Tumski）而具有发展地质旅游的巨大潜力；然而，该地区需要制定地质旅游发展战略。鉴于研究区的形态多样性，有必要在欧洲的这一地区建立一个独特的景观地质解释中心，在整合旅游，特别是地质旅游活动方面发挥作用。

The objective of this research is to investigate the awareness and opinions concerning forest therapy within a public health institution, specifically as a green prescription for patients with stable chronic disease. Through qualitative preliminary analysis, this study compared the responses of a group to gather physical activity and wood frequentation insights, as well as forest therapy patients’ attitudes. The results underline a general predisposition among respondents to engage in moderate physical activity and visit natural environments for relaxation purposes. Emerging parallelly is how forest therapy is largely an unknown practice, although it draws considerable interest and a general predisposition to participate. This research outlines the ideal conditions that emerge for participating in forest therapy sessions, including the availability to pay, pointing toward environmentally and socio-economically sustainable reflections. Further studies should extend this preliminary investigation using appropriate statistical methodologies on larger samples, involving different regions and medical conditions.

Carbon accounting is critical to manufacturing and achieving a low-carbon transition and lean carbon management. A comprehensive understanding of carbon emissions in manufacturing is essential to calculate a product’s carbon footprint accurately. Based on the life cycle assessment (LCA) method, this study divides the whole process of mechanical products from parts to finished products into three stages: parts (P), assembly (A), and testing (T). By decomposing each stage’s carbon emission sources and combining each stage’s characteristics, a series of corresponding carbon emission accounting models is established. Finally, the three-stage carbon emission model of the manufacturing process of a three-piece ball valve is established, and the validity and feasibility of the proposed model are verified. The results show that raw material consumption, energy consumption, and transportation are the primary sources of carbon emissions in the manufacturing process of three-piece ball valves, accounting for 35.6%, 38.8%, and 17.6%, respectively. The corresponding carbon emissions were 17.854 kgCO2e, 19.405 kgCO2e, and 8.8 kgCO2e, respectively. Through these results, we can provide some theoretical and data support for the low-carbon transformation of manufacturing enterprises as well as some research ideas for realizing low-carbon production through process planning and shop scheduling.

Finally, the three-stage carbon emission model of the manufacturing process of a three-piece ball valve is established, and the validity and feasibility of the proposed model are verified. The results show that raw material consumption, energy consumption, and transportation are the primary sources of carbon emissions in the manufacturing process of three-piece ball valves, accounting for 35.6%, 38.8%, and 17.6%, respectively. The corresponding carbon emissions were 17.854 kgCO2e, 19.405 kgCO2e, and 8.8 kgCO2e, respectively. Through these results, we can provide some theoretical and data support for the low-carbon transformation of manufacturing enterprises as well as some research ideas for realizing low-carbon production through process planning and shop scheduling.","PeriodicalId":22183,"journal":{"name":"Sustainability","volume":"74 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142265286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
