As environmental conservation and community development gain importance, ecotourism has emerged as a significant segment of the global tourism industry. However, the cultural factors that drive tourist behavior in this domain remain underexplored. This research examined how power distance belief (PDB), interacts with the type of tourism content shared on social media (conspicuous versus experiential) to influence travelers’ ecotourism intentions. To test our hypotheses, we conducted two experimental studies using a 2 (PDB: high vs. low) × 2 (tourism content type: conspicuous vs. experiential) between-subjects design. Participants for both experiments (N = 480) were recruited through an online survey platform. In the experiments, participants’ PDB was situationally primed, and tourism content type was manipulated using specifically created fictitious posts adapted from a real social media platform. Other key variables were measured using validated multi-item scales. Data were analyzed using analysis of variance (ANOVA) and moderated mediation analysis (PROCESS Model 15). The findings reveal that travelers with high PDB show higher ecotourism intentions when exposed to conspicuous content, whereas travelers with low PDB exhibit higher intentions when exposed to experiential content. This interactive effect is mediated by travelers’ social comparison motives. These findings offer novel insights into the motivations underlying ecotourism behavior by identifying distinct pathways through which social media can promote sustainable tourism behaviors, and provide practical guidance for eco-destination managers to design targeted marketing strategies that encourage sustainable tourism practices across different consumer segments.

Fast fashion is a rapidly expanding sector characterized by high production volumes, low costs, and short product lifecycles. While recent efforts have focused on improving sustainability within supply chains, consumer behavior remains a critical yet underexplored driver of environmental impacts. This study presents a web-based calculator tool designed to estimate both the carbon and plastic footprints associated with individual fast fashion consumption, with a particular focus on shopping behaviors, garment disposal, and laundry habits. Adopting a geographical perspective, the analysis explicitly considers the spatial dynamics of consumption and logistics within the urban context of Milan (Italy), a dense metropolitan area representative of high fashion activity and mobility. By incorporating user-reported travel patterns, logistics routes, and localized emission factors, the tool links consumer habits to place-specific environmental impacts. By involving over 360 users, the tool not only quantifies emissions and plastic waste (including microfibers) but also serves an educational function, raising awareness about the hidden consequences of fashion-related choices. Results reveal high variability in environmental impacts depending on user profiles and behaviors, with online shopping, frequent use of private vehicles, and improper garment disposal contributing significantly to emissions and plastic pollution. Our findings highlight the importance of integrating consumer-focused educational tools into broader sustainability strategies. The tool’s dual function as both calculator and awareness-raising platform suggests its potential value for educational and policy initiatives aimed at promoting more sustainable fashion consumption patterns.

This study investigates the impact of minimalism on ethical consumption within the framework of the Value–Identity–Personal Norms (VIP) model. Data were collected from 340 Turkish consumers using a convenience sampling method and an online survey. Analyses were conducted with SmartPLS, employing the structural equation modeling (SEM) approach to examine the relationships among the constructs. The results reveal that minimalism, conceptualized as a value, significantly shapes environmentally responsible behavior by strengthening environmental identity and personal norms, which in turn drive ethical consumption choices. By extending the VIP model, the research positions minimalism not only as a lifestyle but also as a value-based orientation that aligns with biospheric values in encouraging pro-environmental actions. Furthermore, the study underscores the importance of sustainability communication as a crucial mechanism for reinforcing the connection between minimalistic values and ethical consumer behavior. It also highlights the mediating role of environmental identity between values (both biospheric and minimalistic) and personal norms, supporting the view that values influence behavior indirectly through psychological constructs. Overall, the findings demonstrate that minimalism positively affects environmental identity and personal norms, thereby fostering ethical consumption in line with the theoretical perspectives of the Value–Belief–Norm (VBN) and pro-environmental behavior models. This research provides valuable insights into how minimalism can be integrated into sustainability communication strategies to promote sustainable consumption, particularly in emerging economies.

As a crucial vehicle for advancing the transition to a green low-carbon economy, the green supply chain plays a pivotal role in alleviating pollution pressures and facilitating the green transformation of products. Existing studies mainly focus on static optimization and cost coordination in green supply chains, with limited attention to the dynamic impact of consumer behavior on green production and channel coordination. Based on consumer green preferences and the evolution of reference prices, we developed a differential game model for a two-tier green supply chain composed of a manufacturer and a retailer. The model incorporates green goodwill and consumer memory variables to capture the dynamic interaction among product greenness, sales effort, and consumer perception. By comparing the dynamic optimal response paths under integrated and non-integrated strategies, the study analyzes how reference price effects and goodwill accumulation influence decision-making and system performance. The results show that the stable reference price of green products is significantly higher than the actual selling price. When consumer environmental awareness is strong, cooperative strategies can markedly improve both green performance and supply chain profits, offering potential for Pareto improvement. This research enhances behavior-oriented modeling in green supply chains and provides theoretical and empirical support for designing collaboration mechanisms in green product promotion.

This study examines sustainable consumption intentions among university students in Portugal, a generation increasingly recognized for their ecological awareness but often constrained by structural and social barriers. Within this context, this study explores psychological and behavioral determinants of sustainable consumption and peer recommendation using an integrative framework based on the Theory of Planned Behavior (TPB), the Value–Belief–Norm theory (VBN), and the SHIFT model. Drawing on a survey of 324 students from diverse academic backgrounds, we analyzed how environmental beliefs, consumer habits, and activism influence sustainable consumption intention and recommendation. The analysis, conducted using Partial Least Squares Structural Equation Modeling (PLS-SEM), reveals that environmental beliefs significantly predict both consumer intention and habitual behavior, which in turn affect activism and sustainable consumption. Notably, intention emerges as a key mediator between individual motivations and peer recommendation, while activism and habits do not exert direct influence on recommendation behavior. These findings underscore the importance of moral values, routine behavior, and motivational pathways in shaping sustainable practices, while highlighting the persistent gap between awareness and consistent advocacy. This study offers theoretical and practical insights into how structural and psychological factors can reinforce youth engagement with sustainability. Full article

Goji berry is widely consumed worldwide and holds substantial market value, yet its cultivation faces significant threats from the goji berry psyllid (Bactericera gobica). Chemosensory-related genes play critical roles in regulating insect behaviors, which makes them key molecular targets for the development of environmentally friendly pest control strategies. However, chemosensory genes in B. gobica have not been previously identified or characterized. In this study, we sequenced transcriptomes from the antennae and body tissues of male and female B. gobica and annotated genes associated with chemosensory functions. We identified 15 odorant-binding proteins (OBPs), 18 chemosensory proteins (CSPs), 3 sensory neuron membrane proteins (SNMPs), 26 odorant receptors (ORs), 8 gustatory receptors (GRs), and 32 ionotropic receptors (IRs). Transcriptome data and a quantitative real-time PCR confirmed the tissue-specific expression patterns of these genes, with several genes, including three BgobOBPs, eight BgobCSPs, one BgobOR, two BgobGRs, and two BgobIR, highly expressed in the antennae, suggesting their role in olfactory recognition. BgobGR1 was most highly expressed among GRs, indicating its important role in gustatory perception. We also identified gene BgobGR5 with differential expression patterns between females and males. Our study represents the first characterization of chemosensory genes in a Bactericera species. Full article

Social media has become a tool that exerts a significant influence on consumer behavior. In this sense, this study aims to identify whether digital social influence derived from the informational nature of social media content and online member group support influences the subjective norms and environmental attitudes of organic product consumers. This study was developed using a quantitative, correlational, and cross-sectional design. A total of 371 organic product consumers participated in the study, who were administered a questionnaire consisting of 17 questions measured on a 5-point Likert scale. Statistical analysis was performed using SPSS 24 and Smart PLS, and convergent validity, discriminant validity, and structural equation modeling were applied. The results of the study identified that environmental attitudes continue to be a highly influential factor in organic product purchasing behaviors and that these attitudes are shaped by subjective norms and digital social influencers, such as social media content and online member support groups. Furthermore, the study found that subjective norms mediate the relationship between environmental attitudes and social media content as well as online member support groups. Beyond contributing to the theoretical understanding of environmental attitudes, this study offers practical insights into designing digital marketing strategies that leverage social influence to promote sustainable consumption, particularly in emerging markets.

Plastic waste accumulation is a pressing environmental challenge that demands interdisciplinary solutions. This study investigated whether humanized messaging in green advertisements increases consumers’ conservation intentions. Grounded in self-expansion theory and dual-process theory, we propose a serial mediation model that integrates affective (empathy) and cognitive (perceived responsibility) pathways to explain conservation behavior in humanized environmental campaigns. We conducted a scenario-based experiment (N = 505) to test these mechanisms. Green ads that humanize marine animals significantly increased empathy, perceived responsibility, and conservation intentions. Moreover, the effect of humanized messaging on conservation intentions was sequentially mediated by heightened empathy, which in turn strengthened perceived responsibility. As a pioneering study aiming to propose and empirically test the affective–cognitive pathway, our work provides novel insights into how emotional and rational processes jointly shape environmental decision-making. The findings advance theory on consumers’ conservation behavior and provide actionable guidance for enterprises and policymakers to design evidence-based initiatives for plastic waste reduction.

Green food serves as a bridge connecting healthy lifestyles with environmental values, particularly in the context of sustainable consumption transitions. However, existing research lacks a systematic understanding of how consumers negotiate cognitive evaluations and emotional responses when forming green food purchase intentions. This study addresses that gap by exploring the cognitive–affective negotiation process underlying consumers’ green food choices. Based on 26 semi-structured interviews with Chinese consumers across diverse socio-economic backgrounds, the grounded theory methodology was employed to inductively construct a conceptual model. The coding process achieved theoretical saturation, while sentiment analysis was integrated to trace the emotional valence of key behavioral drivers. Findings reveal that external factors—including price sensitivity, label ambiguity, access limitations, social influence, and health beliefs—shape behavioral intentions indirectly through three core affective mediators: green trust, perceived value, and lifestyle congruence. These internal constructs translate contextual stimuli into evaluative and motivational responses, highlighting the dynamic interplay between rational judgments and symbolic–emotional interpretations. Sentiment analysis confirmed that emotional trust and psychological reassurance are pivotal in facilitating consumption intention, while price concerns and skepticism act as affective inhibitors. The proposed model extends the Theory of Planned Behavior by embedding affective mediation pathways and structural constraint dynamics, offering a more context-sensitive framework for understanding sustainable consumption behaviors. Given China’s certification-centered trust environment, these findings underscore the cultural specificity of institutional trust mechanisms, with implications for adapting the model in different market contexts. Practically, this study offers actionable insights for policymakers and marketers to enhance eco-label transparency, reduce structural barriers, and design emotionally resonant brand narratives that align with consumers’ identity aspirations.

In Thailand, companies are facing increasing pressure from investors, consumers, customers, and regulators to integrate sustainability into business policies and practices. Achieving corporate sustainable development requires incorporating environmental attitudes and work environments into employee behaviors. This study examines how perceived sustainability policies (PSP) influence pro-environmental behaviors (PEB) in the workplace. A total of 589 respondents from four Thai companies in diverse sectors—rubber, consumer products, B2B industrials, and garments—participated in the study. Grounded in the Focus Theory of Normative Conduct, the research extends individual-level psychological frameworks by incorporating the mediating roles of organizational-level descriptive norms—green shared vision (GSV) and green work climate (GWC)—and the moderating role of individual green value (IGV). Structural equation modeling was conducted using AMOS. The findings supported both a direct effect of PSP on PEB and a sequential mediation pathway through GSV and GWC, while the individual mediation roles of GSV and GWC were not significant. These results reflected strong institutional and in-group collectivist culture of Thailand. Moreover, IGV was found to have a significantly negative moderating effect, suggesting that employees with high IGV may rely less on formal perceived sustainability policies in shaping their pro-environmental behaviors.

Background: Understanding the psychological drivers of the energy transition is essential for accelerating the shift to low-carbon societies. The aim of this study is to examine how green consumer values (GCV), energy-saving knowledge (KES) and consumer energy awareness (CEA) jointly shape pro-environmental energy behaviors (EEB), while accounting for citizens’ perceived cost barriers (PESC). Methods: We conducted a nationally representative Computer-Assisted Web Interviewing (CAWI) survey of 1405 Polish households and employed structural-equation modeling to test an integrated framework linking values, awareness, knowledge, perceived costs and two behavioral domains: high-commitment efficiency investments and low-cost curtailment actions. Results: The structural-equation model confirms that green consumer value significantly enhance both knowledge of energy-saving (β = 0.434) and consumer energy awareness (β = 0.185), thereby driving two distinct pro-environmental pathways: high-commitment efficiency investments (energy efficiency behavior) (β = 0.488) and curtailment behaviors (β = 0.355). Green consumer value also reduces perception of energy-saving costs (β = −0.344), yet these costs themselves exert strong inhibitory effects on both energy efficiency behavior (β = −0.213) and curtailment behaviors (β = −0.302). Conclusions: Our findings validate an integrated value–awareness–behavior framework, demonstrating that fostering green values and improving informational access are critical to enhancing energy-saving practices, while cost-reduction measures remain indispensable. Policymakers should combine value-based education, transparent feedback tools and targeted financial incentives to unlock citizens’ full potential in driving the energy transition. Full article

The construction industry is responsible for 50% of mineral resource extraction and 35% of greenhouse gas (GHG) emissions. In this context, concrete stands out as one of the most consumed materials in the world. More than 30 billion tons of this material are produced annually, resulting in the extraction of around 19.4 billion tons of aggregates (mainly sand and gravel) per year. Therefore, it is urgent to develop strategies that aim to minimize the environmental impacts arising from this production chain. Currently, one of the most widely adopted solutions is the production of concrete through the reuse of construction and demolition waste. Thus, the objective of this research is to conduct a systematic literature review (SLR) on the use of recycled aggregates in concrete production, aiming to increase urban resilience by reducing the consumption of natural aggregates. An extensive search was performed in one of the most respected scientific databases (Scopus), and after a careful selection process, the main articles related to the topic were considered eligible through the PRISMA protocol. The selected manuscripts were then subjected to bibliographic and bibliometric analyses, allowing us to reach the state-of-the-art on the subject. The results obtained on the replacement rates of natural aggregate by recycled aggregate indicate that the recommendations vary from 20 to 60%, and these rates may be higher as long as the recycled aggregate is characterized, and may reach up to 100% as long as the matric concrete has a minimum compressive strength of 60 MPa. The specific gravity of most recycled aggregates ranges from 1.91 to 2.70, maintaining an average density of 2.32 g/cm³. Residual mortar adhered to recycled aggregates ranges from 20 to 56%. The water absorption process of recycled aggregate can vary from 2 to 15%. The mechanical strength of mixtures with recycled aggregates is significantly reduced due to the amount of mortar adhered to the aggregates. The use of recycled aggregates results in a compressive strength approximately 2.6 to 43% lower than that of concrete with natural aggregates, depending on the replacement rate. The same behavior was identified in relation to tensile strength. The modulus of elasticity showed a reduction of 25%, and the flexural strength was reduced by up to 15%. Full article

Climate change and environmental degradation require inclusive and multidimensional strategies, in which women from Generation Z are emerging as key actors. This study explores how female university students from this generation perceive and prioritize social, political, economic, and technological dimensions of sustainable development, with a focus on respondents from Europe. A structured survey instrument, based on a SPET model (Social, Political, Economic, Technological), was administered to 834 female students at a highly internationalized university in Poland. The questionnaire was available in Polish and English to account for linguistic and cultural variation within the Western civilizational context. Quantitative analysis revealed that the political dimension—particularly international cooperation and legal regulations—was viewed as the most critical for environmental protection, followed by technological innovation in energy and resource management. Social and economic factors received relatively less emphasis, with skepticism toward consumer-level behavior change and shared economy models. This study offers a meaningful contribution to understanding gender- and generation-specific perspectives on environmental responsibility. It also provides a foundation for the development of socially grounded, culturally sensitive strategies in sustainability education and policymaking, with relevance for both academic researchers and public stakeholders.

Sustainability has an ever-increasing importance in our lives, mainly due to climate changes, finite resources, and a growing population, where each of us is called to make a change. Although climate change is a global phenomenon, our individual choices can make the difference. The transportation sector is one of the largest contributors to global carbon emissions, making the transition toward sustainable mobility a critical priority. The adoption of electric vehicles is widely recognized as a key solution to reduce the environmental impact of transportation. However, their widespread acceptance depends on various technological, behavioral, and economical factors. Within this research we use as an artifact the CO₂ Emission Management Gauge (CEMG) devices to better understand how the manufacturers, with integrated features on vehicles, could significantly enhance sales and drive the movement towards electric vehicle adoption. This study proposes an innovative new theoretical model based on Task-Technology Fit, Technology Acceptance, and the Theory of Planned Behavior to understand the main drivers that may foster electric vehicle adoption, tested in a quantitative study with structural equation modelling (SEM), and conducted in a South European country. Our findings, not without some limitations, reveal that while technological innovations like CEMG provide consumers with valuable transparency regarding emissions, its influence on the intention of adoption is dependent on the attitude towards electric vehicles and subjective norm. Our results also support the influence of task-technology fit on perceived usefulness and perceived ease-of-use, the influence of perceived usefulness on consumer attitude towards electric vehicles, and the influence of perceived ease-of-use on perceived usefulness. A challenge is also presented within our work to expand CEMG usage in the future to more intrinsic urban contexts, combined with smart city algorithms, collecting and proving CO₂ emission information to citizens in locations such as traffic lights, illumination posts, streets, and public areas, allowing the needed information to better manage the city’s quality of air and traffic.

Ultraviolet (UV) and blue-light photodetectors are vital in environmental monitoring, medical and biomedical applications, optical communications, and security and anti-counterfeiting technologies. However, conventional silicon-based devices suffer from limited sensitivity to short-wavelength light due to their narrow indirect bandgap. In this study, we investigate the influence of precursor concentration on the structural, optical, and photoresponse characteristics of nanostructured CdS thin films synthesized via chemical bath deposition. Among the CdS samples prepared at different precursor concentrations, the best photoresponsivity of 21.1 mA/W was obtained at 2 M concentration. Subsequently, a p–n heterojunction photodetector was fabricated by integrating a spin-coated CuSCN layer with the optimized CdS nanostructure. The resulting device exhibited pronounced rectifying behavior with a rectification ratio of ~750 and an ideality factor of 1.39. Under illumination and a 5 V bias, the photodetector achieved an exceptional responsivity exceeding 10⁴ A/W in the UV region—over six orders of magnitude higher than that of CdS-based metal–semiconductor–metal devices. This remarkable enhancement is attributed to the improved light absorption, efficient charge separation, and enhanced hole transport enabled by CuSCN incorporation and heterojunction formation. These findings present a cost-effective, solution-processed approach to fabricating high-responsivity nanostructured photodetectors, promising for future applications in smart healthcare, environmental surveillance, and consumer electronics.
