The rapid urbanization and technological advancements of the recent decades have increased the need for efficient and sustainable transportation solutions. This study examines the acceptance of smart transportation systems (STSs) among residents in Polish cities and explores the impact of these systems on energy-saving behaviors. Using the extended Unified Theory of Acceptance and Use of Technology (UTAUT2) model, which includes the propensity to save energy, this research seeks to understand the determinants of STS adoption. The primary research was conducted using Computer-Assisted Web Interviewing (CAWI). The sample was controlled for gender and place of residence. A sample of 471 individuals meeting the criteria of living in a city with over 200,000 residents and using smart transportation solutions in Poland were selected from the research panel. SmartPLS 4 software was used to analyze the collected data. The findings reveal that the propensity to save energy significantly influences perceived usefulness, ease of use, social influence, and hedonic motivation toward STSs. Perceived usefulness and ease of use were found to be strong predictors of the intention to use STSs, while perceived costs had a negative impact on it. This study also identified the moderating role of personal innovativeness in mitigating cost concerns. These insights underscore the importance of emphasizing energy conservation benefits and user-friendly features in promoting the use of STSs. This study concludes that aligning technological innovations with user motivations for energy conservation can enhance the adoption of sustainable transportation solutions, contributing to smarter and more sustainable urban environments.

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.

(1) Background: Consumer switching behavior was one of the expected outcomes of the ongoing competitive reform in the European electricity industry. The aim of this study is to analyze the factors that affect the intention of consumers to switch from their incumbent supplier, who has a strong market position. This article follows the trend of describing and analyzing the situation of incumbent energy suppliers after energy market liberalization. (2) Methods: The research goal was to verify seven research hypotheses regarding switching intentions on the Polish energy market. For this purpose, structural equation modeling analysis using AMOS 29 was conducted. The survey was carried out in 2020, before the SARS-CoV-2 pandemic in Poland, and the research sample consisted of 1216 adults (clients of the incumbent supplier). (3) Results: Special attention was given to customers’ resistance to change, as it was found to be a factor that can impact customers’ decisions to switch, both directly and indirectly. Resistance to change can affect the trust that customers have in their current supplier’s brand, their perception of the costs involved in switching, and their intention to switch. The research also highlighted the importance of brand trust and perceived ease of change in the customers’ decision-making process. (4) Conclusions: An important factor that reduces switching behavior is the customer’s resistance to change; brand trust is a valuable asset that also reduces switching intention.

Shopping cart abandonment remains one of the most significant challenges in e-commerce, generating substantial revenue losses and reducing the effectiveness of sales activities conducted in digital environments. As digital commerce evolves, understanding the role of sustainability motives in online purchasing decisions has become increasingly important. Although previous studies have focused primarily on the role of perceived risk, purchase-related costs, and barriers encountered during the transaction process, considerably less attention has been devoted to the influence of sustainable consumption motives on consumers’ perceptions of these factors. The aim of this study was to examine the relationships between sustainable consumption motives with perceived costs, perceived risk, and transaction inconvenience associated with online shopping, as well as to investigate the influence of these factors on young e-consumers’ shopping cart abandonment behavior. Data were collected using the Computer-Assisted Web Interviewing (CAWI) method among Polish consumers aged 18–34 who had experience with shopping cart abandonment. A total of 455 valid questionnaires were analyzed using partial least squares structural equation modeling (PLS-SEM). The results indicate that sustainable consumption motives significantly increase perceived costs, perceived risk, and transaction inconvenience associated with online shopping. Transaction inconvenience was the only factor that predicted shopping cart abandonment in the hypothesized positive direction; perceived risk showed a significant negative relationship, whereas perceived cost was nonsignificant. Furthermore, sustainable consumption motives exerted an indirect relationship with shopping cart abandonment through transaction inconvenience. The findings extend current knowledge on shopping cart abandonment by demonstrating that sustainable consumption motives influence the way consumers evaluate the online purchasing process. The study contributes to the literature on consumer behavior in the digital economy and provides practical implications for companies seeking to reduce shopping cart abandonment while addressing the growing importance of sustainable consumption.

Background/Objectives: Online food purchasing may be associated with health-related, environmental, economic, and technological factors. However, limited evidence exists on whether these factors are associated with online food purchase frequency in similar ways across generational groups. This study examined whether self-reported healthy eating, environmental concern, and economic decision indicators were associated with online food purchase frequency among Polish consumers who had previously purchased food online and whether these associations differed across birth-cohort groups. Methods: Data were collected in Poland in 2025 in a cross-sectional study using Computer-Assisted Web Interviewing. The analytical sample comprised 669 respondents who declared having purchased food online. Online food purchasing was measured both as a binary distinction between frequent and occasional purchasing and as an eight-category ordinal frequency variable. Pearson’s chi-square tests, Mann–Whitney U tests, binary logistic regression, and ordinal logistic regression were applied. Moderation was assessed through predictor-by-generation interaction terms. The Benjamini–Hochberg procedure was used to control the false discovery rate, and seven economic decision-making indicators were additionally examined in mutually adjusted multivariable models. Ordinal models were interpreted as sensitivity analyses because the proportional-odds assumption was not fully satisfied. Results: Healthy eating was not directly associated with online food purchasing frequency and did not interact significantly with generation. Environmental concern showed a significant interaction with generation in both binary and ordinal models. It was associated with more frequent online food purchasing among Baby Boomers but with less frequent purchasing among Generation Z. In separate models, price comparison and careful product choice were associated with more frequent online purchasing. Saving orientation also showed an exploratory interaction with opposite directions across generational groups: it was associated with more frequent purchasing in Generation X and less frequent purchasing in Generation Z. However, these economic decision indicators did not remain robust after correction for multiple testing and simultaneous adjustment. Conclusions: Online food purchasing frequency was not uniformly associated with health, environmental, or economic tendencies across generations. In this cross-sectional sample, generation moderated the association between environmental concern and online food purchase frequency, although this pattern should not be interpreted as evidence of a distinct causal cohort effect. The findings suggest that similar declared tendencies may be associated with different patterns of online food purchase frequency across generational groups.
