This study explores the role of egoistic and altruistic values on green real estate purchase intention among young consumers in Canada aged between 20 and 40 years. In addition, this study examines the mediating effects of pro-environmental self-identity between social consumption motivation and green real estate purchase intention. A quantitative cross-sectional research design with an explanatory nature is employed. A total of 432 participating consumers in Canada, comprising 44% men and 48% women, with a graduate educational background accounting for 46.7%, and the ages between 24 and 35 contributing 75.2%, were part of the study, and the data collection used a survey method with a purposive sampling, followed by a respondent-driven method. Descriptive and inferential statistics were performed on the scales used for the study variables. A structural equational model and path analysis were conducted to derive the results, and the relationships were positive and significant. The study results infer the factors contributing to green real estate purchase intention, including altruistic value, egoistic value, social consumption motivation, and pro-environmental self-identity, with pro-environmental self-identity mediating the relationship. This study emphasizes the relevance of consumer values in real estate purchasing decisions, urging developers and marketers to prioritize ethical ideas, sustainable practices, and building a feeling of belonging and social connectedness. Offering eco-friendly amenities and green construction methods might attract clients, but creating a secure area for social interaction is critical. To the best of the authors’ knowledge, this research is the first to explore the role of egoistic and altruistic values on purchase intention, mainly in the housing and real estate sector, with the target consumers being young consumers in Canada.

Environmental protection has become one of the key challenges of our time. This has led to an increase in pro-environmental activities in the field of cosmetics and household chemicals, where manufacturers are increasingly trying to meet the expectations of consumers who are aware of the potential risks associated with the production of cosmetics and household chemistry products. This is one of the most important challenges of today’s industry, given that some of the raw materials still commonly used, such as surfactants, may be toxic to aquatic organisms. Many companies are choosing to use natural raw materials that have satisfactory performance properties but are also environmentally friendly. In addition, modern products are also characterized by reduced consumption of water, resources, and energy in production processes. These measures reduce the carbon footprint and reduce the amount of plastic packaging required. In the present study, seven formulations of environmentally friendly car shampoo concentrates were developed, based entirely on mixtures of bio-based surfactants. The developed formulations were tested for application on the car body surface, allowing the selection of the two best products. For these selected formulations, an in-depth physicochemical analysis was carried out, including pH, density, and viscosity measurements. Comparison of the results with commercial products available on the market was also performed. Additionally, using the multiple light scattering method, the foamability and foam stability were determined for the car shampoos developed. The results obtained indicate the very high application potential of the products under study, which combine high performance and environmental concerns. Full article

Volatile organic compounds (VOCs) are highly volatile chemicals in natural and anthropogenic environments, significantly affecting indoor air quality. Major sources of indoor VOCs include emissions from building materials, furnishings, and consumer products. Natural wood products release VOCs, including terpenes and aldehydes, which exert diverse health effects ranging from mild respiratory irritation to severe outcomes, such as formaldehyde-induced carcinogenicity. The temporal dynamics of VOC emissions were investigated, and the toxicological and physiological effects of the VOCs emitted by two types of natural wood, Korean Red Pine (Pinus densiflora) and Japanese Cypress (Chamaecyparis obtusa), were evaluated. Using female C57BL/6 mice as an animal model, the exposure setups included phytoncides, formaldehyde, and intact wood samples over short- and long-term durations. The exposure effects were assessed using oxidative stress markers, antioxidant enzyme activity, hepatic and renal biomarkers, and inflammatory cytokine profiles. Long-term exposure to Korean Red Pine and Japanese Cypress wood VOCs did not induce significant pathological changes. Japanese Cypress exhibited more distinct benefits, including enhanced oxidative stress mitigation, reduced systemic toxicity, and lower pro-inflammatory cytokine levels compared to the negative control group, attributable to its more favorable VOC emission profile. These findings highlight the potential health and environmental benefits of natural wood VOCs and offer valuable insights for optimizing timber use, improving indoor air quality, and informing public health policies.

Consumers have a key influence on reducing the energy and material flow (EMF) in economic processes and thus on minimizing the negative impact on the environment and climate (NIEC). A decisive factor for sustainable development will be the consumers’ willingness to adopt pro-environmental behaviors or taking action oriented towards reducing the environmental and climate impact of consumption. The authors try to answer the question of how to influence consumers to reduce their consumption. This study explores whether consumer behavior is best influenced through awareness campaigns, regulatory policies, economical incentives, or implicit design strategies. The aim of the research presented in this article is to provide the answer to the questions posed. This research consisted of preparing a questionnaire and conducting it on a group of 122 respondents aged 20–40 in Poznan (Poland). The results of the research indicate the validity of supporting the limitation of consumption with external stimuli. In the opinion of the respondents, the availability of products with high durability and reliability received the most indications as a factor limiting consumption. Full article

The development of artificial intelligence has enabled the automation of an increasing number of processes and actions in the online environment, from creating unique and engaging content to simulating user behaviors (likes, comments, reviews). This automation has brought several positives to the online environment, including reduced working time and better results, among others. However, at the other end of the spectrum, consumer trust is starting to decline. Before the advent of artificial intelligence, reviews were often the opinions of other customers who had tried the product or service in question. With the evolution of these reviews, providers can now automatically post them to create a favorable image. Given the increasing concern among young people about environmental issues, this study investigates how AI-generated content affects their trust in sustainability-related online reviews and how this trust influences their pro-environmental purchasing decisions. Quantitative research was conducted in the article, based on which a conceptual model of the degree of trust users have in online reviews and reactions in the context of artificial intelligence was developed. The research methodology involved conducting quantitative research and constructing variables based on the data collected. The results revealed significant links between the evolution of artificial intelligence and the degree of trust users place in general feedback found in online environments. Full article

Understanding consumer heterogeneity is crucial for analysing attitude formation and its role in innovation diffusion. Traditional top-down models struggle to reflect the nuanced characteristics and activities of the consumer population, while bottom-up approaches like agent-based modelling (ABM) offer the ability to simulate individual decision-making in social networks. However, current ABM applications often lack a strong theoretical foundation. This study introduces a novel, theory-driven ABM framework to examine the heterogeneity of consumer attitude formation, focusing on electric vehicle (EV) adoption across consumer segments. The model incorporates non-linear decision-making rules grounded in established consumer theories, incorporating Rogers’s Diffusion of Innovations, Social Influence Theory, and Theory of Planned Behaviour. The consumer agents are characterised using UK empirical data, and are segmented into early adopters, early majority, late majority, and laggards. Social interactions and attitude formation are simulated, micro-validated, and optimised using supervised machine learning (SML) approaches. The results reveal that early adopters and early majority are highly responsive to social influences, environmental beliefs, and external events such as the pandemic and the war conflict in performing pro-EV attitudes. In contrast, late majority and laggards show more stable or delayed responses. These findings provide actionable insights for targeting segments to enhance EV adoption strategies. Full article

The challenges associated with climate change have led to the need for pro-environmental behaviors, including the consumption of sustainable novel foods. Despite the importance of sustainable food for the environment, there is still a need to further investigate the psychological determinants of consumer behavior change putatively able to promote the use of novel foods. In line with this, the aim of the present study was to investigate the role of readiness to change (RTC) in shaping the intention to consume sustainable foods (e.g., chia seeds and edible insects). RTC refers to a valuable construct composed of seven different dimensions, namely perceived importance of the problem/change, motivation, self-efficacy, effectiveness of proposed solution, social support, action and involvement, and perceived readiness. In keeping with this, a cross-sectional study was conducted by collecting from 1252 participants through an online and anonymous survey. In line with the aim above, a linear discriminant analysis was performed to explore potential non-linear relationships between RTC and novel food consumption. The results highlighted certain RTC dimensions (e.g., perceived importance of the problem, action, and self-efficacy) able to positively support the intention to consume novel foods (e.g., chia seeds and spirulina algae). In conclusion, the study pointed out evidence regarding psychological determinants in terms of RTC able to improve sustainable behaviors, namely the use of novel foods. In the context of sustainability, the present study represents a groundwork for the implementation of future studies in this field of research as well as the development of future policies aimed at promoting awareness and encouraging the adoption of sustainable eating behaviors.

Plastic waste reduction has become a global priority, with consumer engagement playing a crucial role in the success of sustainability initiatives. This study examines the demographic and behavioral determinants of consumer engagement in plastic tableware reduction. Using survey data from Hong Kong residents and a Multivariate Analysis of Variance (MANOVA) approach, this study analyzes how age, gender, education, income, housing type, order frequency, opt-out effectiveness, and their interactions influence the four dimensions of engagement, namely plastic tableware opt-out behavior, support for government policies, support for plastic-free restaurants, and price sensitivity. The results indicate that age significantly affects plastic tableware reduction engagement, with order frequency and opt-out effectiveness moderating the effects of age and education. The study contributes to the literature by providing empirical insights into consumer-driven sustainability efforts and the role of behavioral factors in shaping engagement in plastic waste reduction. These findings offer valuable implications for policymakers and businesses promoting sustainable consumption practices. Full article

This study investigates the influence of digital skills, personal innovativeness, and attitudes toward smart home adoption on digital consumer behavior in Poland, as well as the relationship between digital activity and environmental awareness. In the context of growing interest in sustainable development and digital responsibility, the research aims to identify the psychosocial and technological determinants of conscious online behaviors. The study employs a structured survey (n = 1246) using validated scales, which were analyzed through Confirmatory Factor Analysis (CFA) and Structural Equation Modeling (SEM). The findings reveal that personal innovativeness is the strongest predictor of digital consumer behavior, followed by digital skills and, to a lesser extent, smart home adoption. Moreover, digitally active consumers demonstrate significantly higher levels of environmental awareness, suggesting that digital engagement fosters pro-environmental attitudes. Gender differences were observed in the strength of these relationships, with digital skills and innovativeness having a greater impact on women’s behavior, while smart home technology attitudes were more relevant among men. These results contribute to the understanding of digital consumer responsibility and its environmental implications, highlighting the importance of digital competence development and technological openness in promoting sustainable consumption patterns.

This paper examines the phenomenon of collaborative consumption among Generation Z in Ukraine, focusing on its significance for sustainable consumption and the factors driving its popularity. In the context of increasing digitalization and environmental challenges, the authors analyze the extent to which young Ukrainians engage in the sharing economy and the motivations behind their choices. Special attention is given to the unique characteristics of Generation Z in Ukraine, who, unlike their Western peers, are marked by a strong sense of patriotism, greater social responsibility, and a desire for economic stability—factors influenced by the country’s challenging geopolitical situation. The study was conducted using an online survey (CAWI) with a sample of 292 respondents in 2024. The results indicate that 54.8% of the respondents show a propensity for collaborative consumption (PCC), with key motivators being convenience (90%), the need for social connections (70%), and environmental awareness (68%). Individuals inclined toward resource sharing tend to exhibit greater openness, loyalty, and innovativeness. However, the lack of significant differences in their broader sustainable consumption behaviors suggests that collaborative consumption is perceived primarily as a practical solution rather than a consciously pro-environmental strategy. These findings have important practical implications—companies should focus on building trust in sharing platforms, offering flexible pricing models, and emphasizing both financial savings and environmental benefits. Meanwhile, policymakers can support the growth of the sharing economy through regulations that foster innovation and educational campaigns promoting sustainable consumer behavior. Full article

Hydrogen (H₂) production from biomass has emerged as a promising alternative to fossil-based pathways, addressing the global demand for low-carbon energy solutions. This study compares the environmental impacts of two biomass-based H₂ production processes, biogas reforming and agricultural residue gasification, through a life cycle assessment (LCA). Using real-world data from the literature, the analysis considered key system boundaries for each process, including biogas production, reforming, and infrastructure, for the former, and biomass cultivation, syngas generation, and offgas management, for the latter. Environmental impacts were evaluated using SimaPro software (Version 9.4) and the ReCiPe midpoint (H) method. The results revealed that biogas reforming emits approximately 5.047 kg CO₂-eq per kg of H₂, which is 4.89 times higher than the emissions from agricultural residue gasification (1.30 kg CO₂-eq/kg H₂), demonstrating the latter’s superior environmental performance. Gasification consumes fewer fossil resources (3.20 vs. 10.42 kg oil-eq) and poses significantly lower risks to human health (1.51 vs. 23.28 kg 1,4-DCB-eq). Gasification water consumption is markedly higher (5.37 compared to biogas reforming (0.041 m³/kg H₂)), which is an important factor to consider for sustainability. These findings highlight gasification as a more sustainable H₂ production method and emphasize its potential as an eco-friendly solution. To advance sustainability in energy systems, integrating socio-economic studies with LCA is recommended, alongside prioritizing agricultural residue gasification for hydrogen production.

In the context of growing environmental concerns and the demand for more sustainable manufacturing practices, this study evaluates the environmental and economic performance of two production routes for a stainless steel support block used in steel mills. A comparative Life Cycle Assessment (LCA) and Life Cycle Costing (LCC) were conducted to assess a conventional subtractive manufacturing process based on Computer Numerical Control (CNC) machining versus a hybrid approach that combines Plasma Arc-Wire Arc Additive Manufacturing (PA-WAAM) with CNC finishing. The LCA was carried out using ReCiPe 2016 Midpoint and Endpoint methodologies in SimaPro, while the LCC employed a cradle-to-gate cost model. Results showed that the hybrid WAAM-CNC route reduced average environmental impacts by 49% across 18 categories and decreased steel consumption by approximately 70% due to near-net-shape fabrication. Although the hybrid method incurred an approximate 3.5 times increase in unit production cost, this was primarily attributed to equipment investment. In contrast, operational costs such as labor, materials, and consumables were significantly lower—by 66%, 28%, and 45%, respectively. These findings support the hybrid approach as a more sustainable manufacturing alternative with the potential for long-term cost optimization as additive technologies mature. Full article

Environmental protection is a core component of the sustainable business practices of financial institutions. Previous research on green FinTech mainly relies on gas and dust emissions data to show its environmental impact, while consumer assessments of FinTech’s contribution to sustainability are rarely explored. This study aims to investigate the level of consumer awareness regarding the environmental impact of FinTech companies and to identify cross-country differences in these assessments. The empirical data were obtained from a survey conducted in mid-2023, involving 2000 respondents from the United Kingdom, Germany, Poland, and Ukraine. This study employs descriptive statistics and selected statistical tests, which enabled the identification of two main findings. Firstly, the survey results reveal a generally low level of awareness of the green activities undertaken by FinTech companies across all four countries. Secondly, statistically significant differences were found in the assessment of the environmental impact of FinTech companies, with respondents from the United Kingdom and Poland being the most likely to perceive this impact as positive. Due to the benefits of sustainable development for both society and the environment, it is essential that the FinTech sector intensifies its pro-environmental efforts. The findings also highlight the need for FinTech companies to enhance communication regarding their environmental sustainability initiatives. Full article

Given the importance of phenolic compounds and antioxidant capacity in plant defense and human health, this study aimed to evaluate black cherry tomatoes’ polyphenol, flavonoid, anthocyanin, and carotenoid content and enzymatic activity under greenhouse conditions. Black cherry tomato varieties—Indigo Cherry Drops, Indigo Rose, and Kumato—were cultivated from seed to the third harvest. Total polyphenols, flavonoids, anthocyanins, β-carotenoids, antioxidant capacity 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), and enzymatic activities, including superoxide dismutase (SOD), catalase (CAT), proline (PRO), and superoxide dismutase (PAL), were measured and compared. The Kumato variety exhibited significantly higher total polyphenols, flavonoids, and carotenoids, along with enhanced antioxidant activity (DPPH, ABTS) and enzymatic activity (CAT, PAL) compared to Indigo Rose and Indigo Cherry Drops, with free radical inhibition of 87.0% (DPPH) and 74.72% (ABTS). SOD activity was highest in Indigo Rose (0.21 U/mg protein), while proline levels were significantly higher in Kumato and Indigo Cherry Drops (6.40 and 6.63 U/mg protein). These findings highlight the antioxidant potential of black cherry tomatoes and their high potential nutritional value for consumers. Future research should explore how environmental factors influence their biochemical composition and potential applications in functional food. Full article

Background: Current research inadequately substantiates the impacts of dietary inflammatory potential based on the dietary inflammatory index (DII) on population health and environmental sustainability in Chinese adults. Objectives: We aimed to investigate the associations between the DII with the risk of all-cause mortality and greenhouse gas (GHG) emissions in Chinese adults. Methods: Data from adults (N = 15,318) in the China Health and Nutrition Survey 1997–2015 wave were included in the analysis. DII and energy-adjusted DII (E-DII) were calculated using dietary intake data collected with a combination of 3-day consecutive 24-h dietary recalls and the food weighing method. The total GHG emissions were calculated by summing the amount of emissions from all the food groups consumed by the participants. Cox proportional hazards regression models and linear regression models were conducted for statistical analysis. Results: A pro-inflammatory diet, as reflected by higher DII and E-DII scores was associated with an increased risk of all-cause mortality (DII: Q5 vs. Q1: HR = 1.82; 95% CI: 1.45–2.30; p-trend < 0.0001; E-DII: Q5 vs. Q1: HR = 1.86; 95% CI: 1.38–2.52; p-trend < 0.0001) and higher amounts of GHG emissions (both p-trend < 0.0001). Conclusions: These findings demonstrated positive associations between pro-inflammatory potentials with an increased risk of all-cause mortality and higher GHG emissions among Chinese adults, suggesting dual adverse impacts of a pro-inflammatory diet on health and environmental sustainability.
