Muslim Intention to Buy Sustainable Modest Fashion: A Value-Attitude-Behavior Approach

Purpose: To analyze the factors that influence the intention of Muslims to sustainable modest fashion. Design/methodology/approach: using quantitative methods. The analytical technique used is Partial Least Square-Structural Equation Modeling (PLS-SEM) with 220 respondents as a sample of Muslims in Bandung City, Indonesia. Findings: The results showed altruism, egoism, and Islamic religiosity affect attitudes. Then, altruism value, egoism value, and attitude affect purchase intention. However, Islamic religiosity does not affect purchase intention. Practical implications: Entrepreneurs can incorporate the values of altruism and egoism in their marketing communications. In addition to emphasising environmental and social protection aspects, businesses can pay attention to the aesthetics and quality of their products. Meanwhile, the government can provide support through policies and facilities that encourage the production and consumption of products that are in line with sustainable development goals (SDG’s). Originality/value: This study examines the influence of altruistic values, egoistic values, Islamic religiosity, and attitudes on purchasing intentions in one theoretical framework. This research specifically focuses on one type of fashion product, namely modest fashion, which has not been widely studied in previous research in the realm of sustainable consumption.

TVARUMO ASPEKTAS RENGIANT STEAM PROJEKTUS PRADINIAME UGDYME

STEAM education is identified as one of Lithuania's educational priorities and has been taking root in primary education over the last decade in the form of various creative and/or exploratory projects for students. As education experts analyze the aims and outcomes of STEAM education, it is noticeable that the rapid increase in the number of STEAM projects is resulting in a decrease in the number of relevant real-life problems and solutions that incorporate sustainability aspects. To find out how future primary school teachers consider sustainability in STEAM projects, a qualitative research methodological approach (focus group discussion) and qualitative content analysis were applied. The results of the study revealed that primary teachers perceive sustainability in STEAM projects as environmental knowledge, encouraging students to be responsible consumers, and teaching them how to find and make reasonable solutions to problems. The results of this study do not allow for drawing broad and generalized conclusions, but point to the need to review more carefully the information and assignments presented during the placement year from the sustainability perspective, to encourage students to design and implement different STEAM project models and to critically evaluate them in the context of students' sustainability competence development, and to encourage the primary teachers' readiness to develop sustainability competences in STEAM projects remains a relevant area for further research. Keywords: STEAM project, sustainability, future primary school teachers

I Know I Am Ugly, but Please Listen to My Story First: An Examination of How Storytelling Can Impact Consumers' Valuation of Unattractive Produce

ABSTRACTIn a world where food insecurity and food waste paradoxically coexist, the rejection of aesthetically imperfect yet edible produce significantly contributes to food waste. This study examines the application of compelling storytelling to alter consumer perceptions and behaviors toward unattractive produce, a perspective largely overlooked in sustainability research. We address this gap by exploring how storytelling can mitigate cognitive biases against such produce, thereby enhancing consumer acceptance through improved perceived taste. In Study 1, we examine the effect of unattractive produce on produce valuation and the mediation of perceived taste. In Study 2, we investigate the moderating role of storytelling in enhancing consumers' perceived taste of unattractive food. Through two experimental studies, we confirm that combining storytelling with marketing tactics, such as coupons, significantly increases consumers' consumption of unattractive produce. We recommend retailers utilize storytelling in marketing unattractive produce to optimize marketing effectiveness and promote sustainable food consumption. Our findings advance storytelling, visual marketing, and unattractive produce literature and offer practical insights for reducing food waste, contributing to sustainability efforts and social welfare. By employing a storytelling strategy, we support social good by encouraging the consumption of “ugly” produce.

Exploring Green Consumerism: The Impact of Environmental Knowledge, Social Influence, and Attitudes on Millennials' Purchase Intentions

Indonesia is experiencing a demographic bonus, where millennials make up a significant portion of the productive age population. This demographic shift presents challenges in meeting labour market demands, as well as consumption patterns, particularly concerning sustainable consumption. Simultaneously, environmental issues such as climate change and unsustainable resource usage have become pressing global concerns. Millennials have a crucial role in addressing these challenges by adopting environmentally friendly behaviours, including green product consumption. However, the factors that drive millennials' green purchase intentions, particularly in Indonesia, remain understudied. This study aims to investigate the influence of environmental knowledge, environmental concern, social influence, and attitude on the green purchase intentions of Indonesian millennials. The research employs a quantitative descriptive approach, using purposive sampling to collect data from 150 millennials in Banjarmasin. Data were analyzed using Structural Equation Modeling (SEM) through the Partial Least Squares (PLS) method. The findings reveal that environmental concern indirectly affects green purchase intention through the mediating role of attitude. Additionally, social influence and environmental knowledge have significant positive impacts on both attitude and green purchase intention. The study highlights the importance of enhancing environmental knowledge and leveraging social influence to encourage sustainable purchasing behaviour among millennials. Marketers can use these insights to design effective strategies that promote eco-friendly products to this demographic. Future research could explore other factors, such as perceived product quality and price sensitivity, to gain a more comprehensive understanding of green consumer behaviour.

The Role of Perceived Authenticity in Increasing Green Purchase Intention: Systematic Literature Review

This study explored the relationship between perceived authenticity and consumer purchase intention in green products, especially in the context of increasing awareness of sustainability among consumers. Using the Systematic Literature Review (SLR) method, this research explores the dynamics of the relationship between perceived authenticity and consumer intention for green products. Analysis of key findings reveals that perceived authenticity is not just a concept but is a key element that forms the basis of consumer trust in brands and products. The results of this study highlight the important role of perceived authenticity as the main instrument in forming positive relationships between brands, consumers and green products. The implications are particularly relevant in a marketing context, where strategies that establish and maintain product authenticity are crucial. This study provides in-depth insight into how perceived authenticity not only influences consumers' perceptions of the sustainability of green products but also directly impacts purchase intention. This study also emphasizes the importance of marketing strategies that build and maintain perceived authenticity. This strategy not only helps brands win consumer trust but also becomes a catalyst in driving change towards more sustainable and responsible consumption. Thus, this study significantly contributes to business practitioners and academics in understanding the dynamics of the green product market amidst the shift in consumer values towards sustainability.

(Re)conceptualising consumer interdependency of care: Persistent struggles with dependency and responsibility

This conceptual paper explores how consumers become entangled in persistent struggles of care in consumption. While extant marketing theory focuses on the neoliberal responsibility of care as an autonomous and independent act, we problematise and extend the current theorisation of consumers’ struggles of care by examining the interrelated struggles of consumer responsibility of care and market relations of care. Building on marketing and interdisciplinary insights, we develop a novel lens of consumer interdependency of care to capture how a consumer responsibility is negotiated within varied relations of care. We contribute to a holistic and critical understanding of care in consumption as a problematic interplay between a responsibility of care and a dependency of care. By examining three types of consumer interdependency across consumption contexts, we discuss challenges and future research direction in the provision, mediation, and positioning of care, and bring critical attention to the power imbalances of care and consumer vulnerability.

Efficiency of Sustainability Cues in Consumer Choices of Seafood—Consumer Segments and Willingness to Pay in Southern China

Achieving sustainability goals in the food system should be informed by consumer demand that signals the market trend and drives systemic changes. This study examines the efficiency of sustainability cues in influencing consumer choices of seafood among consumers in Southern China. The preference and willingness to pay for each seafood attribute are estimated using the Latent Class Logit model. The results show that respondents strongly believed in governmental certifications and were more willing to pay for domestic seafood certified to public standards over imported seafood with third-party sustainability certifications. By integrating individual characteristics into the membership function, this study finds that the preference for sustainability cues and other authenticity cues is related to seafood consumption habits and education. The study highlights the efficiency heterogeneity of sustainability cues, providing valuable insights for formulating public policy and developing marketing strategies that promote sustainable consumption.

Understanding the Intention Behind Muslim Consumers’ Decision to Purchase Green Products

The increasing global emphasis on sustainability has significantly influenced consumer behaviour towards green products. However, the specific factors driving green purchase intention (GPI) remain insufficiently explored in the literature. This study examines the determinants of GPI among Muslim consumers in Banjarmasin, focusing on three critical variables: green product knowledge (GPK), plastic ban policy (PBP), and religiosity. A quantitative research approach was utilized, involving data collection through a structured questionnaire administered to 465 respondents aged 18 and older with prior experience purchasing green products. The study employed PLS-SEM with SmartPLS version 3 for the analysis. The results is insignificantly influence GPK on GPI statistically. In a different way, PBP shows a significant effect on GPI, highlighting the effectiveness of regulatory measures to encourage sustainable behaviour. Additionally, religiosity shows a significant positive influence on GPI, indicating that moral and ethical considerations rooted in religious beliefs are crucial in shaping consumer attitudes towards green purchasing. This research enriches the literature by merging regulatory, cognitive, and cultural viewpoints to deepen understanding of green consumer behaviour. It also provides actionable insights for policymakers and marketers to encourage sustainable consumption practices.

Going circular with what we wear and how we build: parallelisms between the Dutch and French catwalks of fashion and construction

Responding to the call for circular transition, the Dutch and French governments aspire to achieve a fully circular economy by developing a transitional agenda in various sectors, including fashion and construction. The two countries are among the top 10 waste generators in the European Union (EU), while the two sectors—fashion and construction—are the largest polluters in the EU. The aim of this study, and its main contribution, is to harmonize circular design principles, which vary by sector into common types, and identify the circular design principle that balances the sustainability dimensions the most. This responds to research gaps that merely describe these design principles applicable to different sectors but which are also silent on which achieves sustainability balance. Using multicriteria decision analysis, selected case studies of companies in the two sectors and countries were scored and ranked according to environmental, economic, and social sustainability indicators. The case projects were selected based on the circular design principle that the enterprises were applying. These principles were standardized for the two sectors to come up with five distinct types, namely, design for (i) biobased materials, (ii) service/adaptability, (iii) disassembly, (iv) waste and material recovery, and (v) longevity. Three forms of triangulation were used to achieve reliability, validity, and equivalence of the findings: (i) data—by doubling the size of the sample cases to 40 establishments from 20, (ii) investigator—by having the authors score the projects separately, and (iii) method—by using two objective weighting methods in scoring the criteria. These techniques resulted in similar rankings of the cases in terms of triple bottom-line scores per design principle. Designing for biobased materials turned out to achieve the most balance. The case projects were also compared regarding performance in achieving the UN Sustainability Development Goals (SDGs), which companies use to integrate sustainability with business. Circularity in fashion and construction primarily targets responsible consumption, production, and climate action. A tertiary SDG was life on water and access to clean water for fashion and life on land and sustainable cities for construction.

The Diversity of the Circular Economy in the City of Tashkent, Uzbekistan

ABSTRACTUsing Gibson‐Graham's methodology for reading for difference, this article seeks to shed a new light on the circular economy (CE), a concept often promoted, but rarely implemented. By presenting the diversity of practices around the acquisition, repair and resale of second‐hand goods in Tashkent, Uzbekistan, this study provides insight on the circularity of urban environments. The collection and GIS mapping of around 60 interviews with small and medium enterprises involved in responsible consumption and production in Tashkent led to the development of a more accurate definition of the CE in an urban setting. Research results indeed reveal that responsible consumption and production are very dynamic concepts that rely mainly on accessibility, creativity and connectivity with one's surroundings, as well as social networks. In addition, GIS mapping of small businesses in the second‐hand industry showed that the provision of second‐hand‐related services is intricately connected with urban infrastructure.

Consumers’ Perceptions and Behaviors Regarding Honey Purchases and Expectations on Traceability and Sustainability in Italy

Traceability is a cornerstone of sustainable honey production and consumption. Honey fraud and a lack of traceability have been recently highlighted by the European Commission. Innovative systems aimed at guaranteeing food safety ’from farm to fork’ and improved controls are highly recommended. Within the framework of the BPRACTICES project, part of the European Union’s Horizon 2020 research and innovation program, and the ERA-Net SusAn initiative—focused on Sustainable Animal Production Systems—an advanced traceability system has been developed. This system utilizes QR code and radio-frequency identification (RFID) technology, along with a user-friendly web application, to facilitate direct interactions between producers and consumers. Despite existing research, studies on the information needs of Italian consumers regarding honey and its traceability remain limited. Understanding these needs is vital for creating effective communication strategies that enhance consumer satisfaction and trust. This study aims to identify the needs of Italian consumers’ honey during the purchasing and consumption decisions. To explore consumer perceptions, behaviors, expectations, and needs regarding honey, we employed diverse social research methodologies, including a quantitative online survey, paper-and-pencil interviews, and focus groups. The results of this study indicate a robust demand for more information on honey’s origin, production processes, and beekeeping practices, aligning with the recent EU Directive 2024/1438, which mandates clear labeling. Italian consumers would be willing to pay a premium for honey that offers detailed information about production practices and transparency. The positive reception of QR code technology by consumers suggests a growing openness to digital tools that enhance transparency and access to information. Ultimately, this research emphasizes the need for the beekeeping sector to adopt sustainable practices, improve traceability systems, and actively engage with consumers to foster trust and ensure long-term viability in the honey market. By addressing these information needs, the sector can align itself with increasing consumer demand for quality, sustainability, and transparency.

The Influence of Green Advertising and Emotional Factors on Green Consumption

The advanced ideas concerning the protection of the environment, the principles of sustainable consumption have underscored the importance of emotions in consumers actions. This essay looks at the effect of green ads and emotions on green purchasing with the aim of improving the application of marketing strategies in sustainability. The emphasis is made on the interdisciplinary framework that examines the connection between green ads and emotional appeals triggering consumers green purchase intentions. The information gathered about the green advertising and the analysis of impact of emotional variables on consuming eco-products is provided through the literature review. The result also suggests that green advertising, green consumption and emotional factors are highly correlated. Positive emotions affect consumer responses and enhance communications leading to making higher purchase of green products through advertising. The use of appeals in green advertising is helpful in the encouragement of green consumption. Future research should incorporate long-term analyses and cross-cultural research to gain a better understanding of the role of affect in green purchasing decisions.

Exploring Portuguese Consumers’ Behavior Regarding Sustainable Wine: An Application of the Theory of Planned Behavior

Although consumption is the cornerstone of economic growth, it is unquestionably one of the main reasons for the current degradation of the planet. Hence, it is necessary to understand consumers’ different perceptions and behaviors regarding sustainable goods, as the solution will inevitably involve changing behaviors and promoting more sustainable consumption. In light of the challenges posed by sustainability within the wine sector, namely issues related to climate change, chemical exposure, and the availability of water and energy, and considering the industry’s substantial environmental and social impacts, it is important to understand the factors influencing wine consumer behavior. This research explores sustainable wine consumption in Portugal. Based on a sample of 197 valid responses, collected in an online survey that took place from March 20 to April 30 of 2024, and applying the Theory of Planned Behavior (TPB) framework, the current study found that consumers’ intention to consume sustainable wine is influenced by their attitudes, subjective norms, and sustainability awareness. Regarding the individuals’ consumption of sustainable wine, this behavior is influenced by the intention to consume this wine, and by consumers’ perceived behavioral control. The results also concluded that individuals’ intention to consume sustainable wine is significantly different across marital status, professional occupation, level of education, and age. With these valuable insights, this study aimed to increase the available information on sustainable wine consumption, allowing different stakeholders, namely political decision makers, to develop and implement more efficient measures to promote sustainable wine consumption.

Synthesis and reactivity of Nb/graphene-MCM-48 and Al/graphene-MCM-48 IN CO2 chemical fixation

Mesoporous materials such as the Mobil Composition of Matter (MCM), play a crucial role in the chemical fixation of carbon dioxide (CO2). These materials exhibit a porous structure with intermediate-sized pores, providing a high surface area and a uniform pore distribution. The objective of this study is to synthesize the mesoporous material MCM-48 using the ionic solid chloride of 1-hexadecyl-3-methylimidazolium ([C16MI]Cl) as a directing agent and tetraethoxysilane (TEOS) as a silica precursor and apply this material as a catalyst in the cycloaddition reaction of CO2 to propylene oxide to produce propylene carbonate. Compounds such as graphene, aluminum, and niobium are employed in different Si/compound molar ratios (1, 5, and 10) to enhance the material properties. The Nb/Graphene-MCM-48 material with a Si/Nb ratio of 10 demonstrated the best catalytic performance in the CO2 cycloaddition, achieving a yield of 85 % and a selectivity of 99 % for propylene carbonate. The results demonstrate that MCMs are highly efficient in the selective conversion of CO2 into cyclic carbonate, offering promising applications for CO2 emission mitigation. This study advances decarbonization and sustainable development, aligning with the Sustainable Development Goals (SDGs) 3 (Good Health and Well-Being), 9 (Industry, Innovation, and Infrastructure), 12 (Responsible Consumption and Production), and 15 (Life on Land) by promoting technologies that reduce environmental impact and support sustainable industrial practices.

Sustainable Consumption and Residents’ Happiness: An Empirical Analysis Based on the 2021 Chinese General Social Survey (CGSS2021)

Sustainable consumption is a fundamental driver for implementing sustainable development strategies and is crucial in advancing Chinese-style modernization. Utilizing data from the Chinese General Social Survey 2021 (CGSS2021), this study examines the relationship between sustainable consumption and residents’ happiness, classifying its effects into growth and sustainability. The study results show that (1) sustainable consumption positively influences residents’ happiness. (2) Regionally, in the central and western regions, sustainable consumption significantly enhances residents’ happiness, with the sustainable effect surpassing the growth effect. In contrast, in the eastern region, sustainable consumption alone does not substantially improve residents’ happiness; instead, the growth effect predominates. (3) From an urban–rural perspective, sustainable consumption notably impacts happiness in rural areas. In contrast, urban areas primarily benefit from the growth effect of sustainable consumption, with the sustainable effect being less significant. (4) From an age-related perspective, different factors predominantly influence the happiness of various age groups. For young people, health plays a crucial role in their overall happiness. In contrast, middle-aged groups place more importance on their marital status, while older people are primarily concerned with housing conditions. (5) Income analysis shows that income increases substantially impact the happiness of high-income groups compared to low-income groups. Based on these insights, we recommend enhancing education and guidance on sustainable consumption, implementing regionally differentiated policies, increasing support for green consumption in rural areas, developing age-specific policies, and addressing income disparities. These measures can enhance the residents’ happiness more effectively and contribute to sustainable societal development.
