    The Role of Institutional Quality and Environment-Related Technologies in Environmental Degradation for BRICS
    (Elsevier Sci Ltd, 2021-07) Hussain, Muzzammil; Dogan, Eyup
    An expanding body of literature has highlighted the environment-growth nexus. However, the literature is scarce on the role of environmental technologies and institutional quality in environmental pollution. The present study aims to contribute to the existing knowledge by utilizing environment-related technologies (ERT), institutional quality (IQ), and energy consumption to investigate ecological footprints (EF) as a proxy for the environment in BRICS economies in a framework based on environmental Kuznets curve (EKC) theory. By using data from 1992 to 2016, long-and short-term relationships are estimated through cross-section augmented autoregressive distributive lag model, augmented mean group estimator, and common correlated effects mean group. The second-generation econometric tools indicate that IQ and ERT negatively affect ecological footprints, thereby implying reductions in environmental degradation. The EKC hypothesis is not validated, implying that an increase in economic activities causes an increase in pollution. Overall, BRICS economies should improve their quality of institutions and enhance investments in environmental technologies to achieve a sustainable environment in the future. Findings are robust to practical policy implications. (c) 2021 Elsevier Ltd. All rights reserved.

    The Nexus Between Poverty, Inequality and Environmental Pollution: Evidence Across Different Income Groups of Countries
    (Elsevier Sci Ltd, 2022-03) Ehigiamusoe, Kizito Uyi; Majeed, Muhammad Tariq; Dogan, Eyup
    Even though the literature has extensively focused on a number of determinants of environmental pollution, it lacks to incorporate the importance of poverty and inequality on the environment. The nexus of poverty-inequality-environment is indeed in line with the agenda of the United Nations' Sustainable Development Goals. Furthermore, the existing studies usually rely on carbon dioxide (CO2) emissions as the proxy for the pollution in their analysis. This study fills the mentioned gaps by investigating the impacts of income inequality and poverty on environmental pollution using ecological footprint (a comprehensive measure of the pollution) in addition to CO2 emissions for 70 countries categorized by income groups. This research employs the dynamic panel system Generalized Method of Moments (GMM) and the Dumitrescu-Hurlin Granger causality techniques which are strong to several econometric issues that may frequently arise in the estimation procedures. The empirical outcomes show that income inequality and poverty increase carbon emissions and ecological footprint in the entire panel. However, when the panel is split into groups, the results indicate that income inequality mitigates carbon emissions and ecological footprint in high-income group but aggravates them in middle-income group. Though poverty has no significant impact on carbon emissions in high-income group, it raises the levels of carbon emissions and ecological footprint in middle-income group. This study overall implies that income inequality and poverty are significant determinants of environmental pollution. Hence, efforts to abate envi-ronmental degradation should give adequate attention to poverty and inequality in order to attain environmental sustainability.

    Multi-Dimensional Sustainability Evaluation of Indigo Rope Dyeing With a Life Cycle Approach and Hesitant Fuzzy Analytic Hierarchy Process
    (Elsevier Sci Ltd, 2021-08) Fidan, Fatma Sener; Aydogan, Emel Kizilkaya; Uzal, Nigmet
    The dyeing process of denim fabric production has the highest potential for significant environmental and human health impacts of denim production, consuming vast amounts of water, chemicals, and dyes. This study aims to assess the sustainability of indigo rope dyeing (IRD) obtained by designing a new recipe with the chemical alternative assessment method. Not only environmental impacts, but also social, economic, and product quality dimensions were included in the multidimensional sustainability assessment. The hesitant fuzzy analytical hierarchy process (HF-AHP) method was used to determine the criteria weights of the determined dimensions. The environmental and social impacts of the existing and newly designed IRD process were evaluated using the gateto-gate life cycle assessment (LCA) and social life cycle assessment (S-LCA) approach. According to the LCA results, the green IRD process exhibited better performance in terms of all environmental impacts evaluated and the abiotic depletion potential of the conventional indigo IRD process can be reduced by 62.55% by applying the green IRD process. According to the HF-AHP results, the most important criteria were environmental impact with 33%, followed by social impacts with 27%, quality results with 23%, and economic results with 17% in assessing the IRD process's sustainability denim production. These results showed that the sustainability of the IRD process could be improved by substituting the chemicals and dyestuff with green alternatives.

    City Love and Place Quality Assessment of Liveable and Loveable Neighbourhoods in Rotterdam
    (Elsevier Sci Ltd, 2022-08) Kourtit, Karima; Nijkamp, Peter; Tuerk, Umut; Wahlstrom, Mia; Türk, Umut
    After the worldwide interest in global sustainability and climate change challenges, an increasing concern is voiced on local quality of life and neighbourhood liveability. In recent urban studies, human well-being, satisfaction and happiness studies are gaining much popularity in a local context (the 'microcosmic city'). The present study seeks to identify the determinants of the residents' appreciation for their daily environment, called here 'city love'. The latter concept captures both tangible or material aspects of city life ('body') and immaterial and emotional dimensions of local quality of life ('soul'). The present paper seeks to develop and test a new quantitative 'city love' concept, inspired by the soul and body conceptualisation of urban attractiveness for residents and visitors - based on a novel 'feelgood' index (FGI) and a 'human habitat' index (HHI) -, with a view to map out the citizens' contentment or appreciation (called neighbourhood love index - NLI) at a district or neighbourhood scale in the city of Rotterdam. Our study utilises data from a quantitative survey among thousands of residents located in 63 neighbourhoods in this city. In addition, the Rotterdam dataset contains not only survey data, but also register data on these neighbourhoods, e.g., real-estate values, crime statistics, and socio-demographics, while geographical information from OpenStreetMap (OSM) is added as a complement. In addition to a multivariate analysis of the rich data set, the paper employs also a quantile regression analysis extended with fixed effects. The results show that the coefficients of the feelgood index (FGI) and the human habitat index (HHI) decrease slightly as we move up the distribution of the neighbourhood love index (NLI). This means that physical and functional aspects of neighbourhoods, e.g., access to such amenities as public transportation, sport facilities, and also streets with diverse attractions or bikeable and walkable road networks, become more important for the lower end of the distribution of the neighbourhood love index (NLI). Our neighbourhood-specific analyses show that the Rotterdam districts and neighbourhoods differ substantially in many physical and social-emotional respects, which calls for place-based policies and sub-local well-being initiatives.

    An Integrated Life Cycle Assessment Approach for Denim Fabric Production Using Recycled Cotton Fibers and Combined Heat and Power Plant
    (Elsevier Sci Ltd, 2021-03) Fidan, F. S.; Aydogan, E. K.; Uzal, N.
    Due to the increase in consumption and awareness of environmental impacts, switching to new business models has become mandatory in the textile industry. The aim of this study is to investigate the contribution of using mechanically recycled cotton fiber instead of virgin cotton fiber, which is one of the most important raw materials in textiles and grown using a high amount of water and pesticides, and combined heat and power (CHP) plant instead of grid energy in terms of the environmental impacts, cost, and quality of denim fabric product via 8 scenarios using an integrated sustainability assessment approach. The scenarios were identified according to the use of the CHP plant in the manufacturing process and the ratio of recycled cotton fiber used in the product. Environmental impacts were analyzed using the life cycle assessment approach (LCA). Besides the environmental impact analyses, product quality and cost-savings of all scenarios were also examined using TODIM (an acronym in Portuguese for Interactive and Multicriteria Decision Making) method to apply an integrated approach for sustainable denim fabric production. Global warming potential (GWP), acidification potential(AP), eutrophication potential(EP), water use, and cumulative energy demand(CED) were investigated as environmental impact categories in the production of denim fabric. In addition to environmental impact categories washed weight, tear, tensile, and cost-saving were determined as the attributes of TODIM. According to the LCA results, the highest environmental impact improvements were obtained as 98% water use, 90% EP, 74% AP, 63% CED, and 54% GWP for scenario 8 with 100% recycled cotton and CHP plant use. Besides, the use of the CHP plant offered 4% GWP and 0.42% water usage saving regardless of the recycled cotton ratio. In addition, scenario 8 also showed the best performance for the integrated sustainability assessment by TODIM. It is obviously demonstrated that the use of the mechanically recycled cotton as a raw material and CHP plant as an energy source through the manufacturing processes of denim production will facilitate the transfer of traditional linear economy business models of companies to the circular economy.
