Abstract

Environmental education awareness (EEA) often fails to translate into confident environmental action, representing a critical knowledge–action gap in sustainability education. This study investigated whether digital citizenship mediates the relationship between EEA and self-efficacy among university students. A cross-sectional design was employed with 879 Egyptian university students from Al-Azhar University. Participants completed validated instruments measuring EEA, digital citizenship competencies (including internet political activism, technical skills, critical perspectives, and networking agency), and general self-efficacy. Mediation analysis using Hayes’ PROCESS macro revealed that digital citizenship significantly partially mediated the relationship between environmental awareness and self-efficacy, accounting for 21.9% of the total effect. Environmental awareness directly predicted self-efficacy (β = 0.590) and indirectly through digital citizenship (β = 0.166). These findings demonstrate that digital competencies serve as “smart tools” enabling students to transform ecological knowledge into confident environmental agency. The results underscore the necessity of integrating digital citizenship training within environmental curricula to cultivate climate-literate, digitally empowered citizens capable of meaningful contributions to global sustainability and climate action initiatives.

1. Introduction

Environmental Education Awareness (EEA) is a multidimensional construct encompassing environmental knowledge, attitudes, and concern for the natural environment, reflecting the core objectives of international environmental education frameworks that emphasize awareness, sensitivity, and motivation to act [1,2]. Since the landmark 1977 Tbilisi conference, there has been a sustained global policy push to build environmental literacy as a critical response to escalating climate crises [3]. In the context of planetary boundaries and climate urgency, science and environmental literacies have emerged as central enablers of transformative environmental action [4]. Educational institutions worldwide are increasingly integrating sustainability and climate change into curricula, positioning education as a fundamental social intervention for climate stabilization and sustainable development [5]. This global momentum underscores the imperative to understand how EEA develops and translates into effective pro-environmental behavior across diverse populations.
Digital citizenship has emerged as a critical 21st-century competency, transcending traditional notions of online safety to encompass responsible, ethical, and active participation in digitally mediated society [6,7]. As contemporary societies transition toward “digital-first” infrastructures, citizenship itself is increasingly enacted through datafied, networked systems that underpin social, political, economic, and cultural life [8,9]. This transformation necessitates competencies extending beyond technical proficiency to include critical evaluation of information, ethical engagement with digital platforms, and participation in struggles for equality and social justice within digital environments [10,11]. The ubiquity of digital technologies in education, governance, and civic engagement has rendered digital citizenship foundational for navigating misinformation, protecting digital rights, and fostering democratic participation [12,13], making it essential for preparing citizens to function effectively in increasingly datafied democracies.
Although the broader literature distinguishes environmental self-efficacy—defined as an individual’s belief in their capability to perform actions producing desired ecological outcomes—from general self-efficacy, the present study adopts a general self-efficacy framework consistent with Bandura’s foundational theory, examining whether digitally mediated competencies strengthen individuals’ overall confidence in their capability to act across achievement contexts, including environmental ones [14]. This construct encompasses three core elements: a capable agent (“I can do this”), concrete action repertoires (such as waste reduction or advocacy), and specific environmental aims (climate mitigation or ecosystem protection) [15]. Contemporary research positions ESE as the critical psychological bridge transforming environmental knowledge and concern into actual pro-environmental behavior [16,17]. Cultivating belief in oneself represents the ultimate goal of environmental education because information alone proves insufficient; individuals must perceive themselves as capable environmental actors who can meaningfully contribute to solutions [18,19]. This self-trusting agency sustains motivation, fosters resilience against climate anxiety, and enables persistent engagement with complex environmental challenges [20].
The knowledge–action gap illuminates a critical disconnect in which environmental knowledge fails to automatically translate into pro-environmental behavior or self-efficacy [21,22]. Research demonstrates that environmental awareness, while necessary, remains a weak and inconsistent predictor of action without accompanying beliefs in personal capability [23,24]. This phenomenon occurs because system knowledge about environmental problems can produce cognitive dissonance or feelings of helplessness rather than empowerment, particularly when education emphasizes crisis magnitude without cultivating concrete action skills [25,26]. Studies reveal that environmental awareness alone constitutes an insufficient predictor of self-efficacy, with confidence beliefs functioning as a significant intervening mechanism transmitting the effect of ecological knowledge onto pro-environmental outcomes, underscoring the necessity of identifying such mediating pathways—particularly digital citizenship competencies—through which awareness may be effectively converted into confident environmental agency [27]. Without systematic cultivation of action knowledge, mastery experiences, and supportive contexts, elevated awareness frequently stalls at concern rather than evolving into capable, sustained environmental action.
Digital citizenship functions as a critical mediator transforming environmental awareness into self-efficacy by providing “smart tools” that enable students to externalize and enact their knowledge [7,28]. Through information literacy and critical evaluation skills, digital citizenship converts abstract awareness into concrete strategies for navigating digital environments [29,30]. Digital competencies facilitate mastery experiences—the strongest source of self-efficacy—by empowering students to create meaningful outputs such as advocacy campaigns, digital stories, or collaborative projects that express their environmental understanding [31,32]. Research demonstrates that digital skills reduce cognitive strain and enhance domain-specific self-efficacy across disciplines, as tool proficiency strengthens belief in one’s capacity to accomplish tasks [33,34,35]. Digital informal learning and productive tool use partially mediate the relationship between literacy and performance [36], suggesting digital citizenship operationalizes awareness into robust self-belief through cognitive, behavioral, and affective pathways.
The integration of “Green Minds”—defined as environmentally literate, critically conscious individuals possessing the knowledge, attitudes, and motivation necessary to engage with ecological challenges—and “Smart Tools,” referring to the digital citizenship competencies that operationalize such awareness into confident civic action, proves essential for advancing global Sustainable Development Goals, particularly SDG 4 (Quality Education) and SDG 13 (Climate Action). EEA builds climate-literate citizens capable of informed mitigation and adaptation behaviors, directly supporting SDG 4.7’s emphasis on education for sustainable development [37,38]. Digital citizenship enables online activism, social justice engagement, and political commitment to sustainable development through technology-enhanced learning platforms [39,40]. Self-efficacy serves as a psychological foundation for sustained climate action, as educators’ environmental confidence significantly influences how effectively sustainability becomes embedded in teaching practice [41]. Research demonstrates that integrating SDG content through digital tools substantially enhances environmental learning gains and planetary concern [42,43], operationalizing SDG 4.7’s vision of global citizenship education while enabling agentic climate action under SDG 13 [44].
Despite robust independent documentation of digital tools enhancing environmental awareness [45,46] and self-efficacy mediating relationships between digital literacy and various outcomes [33,47,48], international literature lacks integration of these constructs within environmental contexts. Existing research treats digital technologies primarily as neutral delivery mechanisms rather than civic competencies that may bridge the awareness–self-efficacy gap [24,49]. Studies examining environmental self-efficacy as a mediator between attitudes and pro-environmental behavior typically omit digital citizenship pathways [16], while investigations of digital skills mediating performance outcomes focus on non-environmental domains such as entrepreneurship, health self-management, or academic achievement [50,51,52]. No study explicitly conceptualizes digital citizenship as the mediating mechanism through which EEA translates into environmental self-efficacy, representing a critical gap in understanding how participatory digital competencies convert ecological knowledge into confident environmental action.
The present study proposes a conceptual model in which EEA serves as the independent variable that initiates the pathway toward confident environmental action. However, environmental awareness alone does not automatically produce self-efficacy; rather, it must be operationalized through practical competencies that enable individuals to act on their knowledge. Digital citizenship is therefore positioned as the mediating variable, functioning as the functional bridge between knowing and doing—converting ecological knowledge into concrete digital repertoires such as online advocacy, critical information evaluation, and civic networking. These competencies, in turn, generate mastery experiences and agentic behaviors that strengthen individuals’ general self-efficacy beliefs, positioning self-efficacy as the outcome variable reflecting the ultimate translation of environmental awareness into confident, sustained action. This conceptual sequence—from awareness (EEA) → digital empowerment (digital citizenship) → confident agency (self-efficacy)—provides the theoretical backbone of the present investigation.
Given the critical gap in understanding how digital competencies facilitate the translation of environmental knowledge into confident environmental action, the present study aimed to investigate whether digital citizenship mediates the relationship between EEA and self-efficacy among university students. Specifically, this research sought to examine the bivariate relationships among EEA, digital citizenship dimensions, and self-efficacy, and to test the indirect effect of environmental awareness on self-efficacy operating through digital citizenship as a mediating mechanism. By empirically testing this mediation model, this study addresses the identified research gap regarding how participatory digital competencies may serve as “smart tools” that convert ecological knowledge (“green minds”) into confident environmental agency. Understanding this mediating pathway has important theoretical implications for bridging the knowledge–action gap in environmental education and practical implications for designing integrated curricula that combine sustainability content with digital citizenship training to cultivate climate-literate, digitally empowered citizens capable of meaningful contributions to global climate action and sustainable development initiatives.

2. Materials and Methods

2.1. Study Design and Sampling

This study employed a cross-sectional correlational design to examine the mediating role of digital citizenship in the relationship between EEA and self-efficacy. A convenience sampling method was used to recruit university students from Egypt. Two distinct samples were collected: a psychometric sample (N = 614) to validate the measurement instruments and a main sample (N = 879) to test the hypothesized mediation model. Participation was voluntary, and informed consent was obtained from all participants prior to data collection.

2.2. Participants

Participants were students enrolled at Al-Azhar University in Egypt, specifically from the Faculty of Education for Boys in Cairo, the Faculty of Education for Girls in Cairo, and the Faculty of Education for Boys in Tafhna Al-Ashraf. The demographic characteristics of both samples are presented in Table 1. The psychometric sample consisted of 614 university students aged 18 to 24 years (M = 21.08, SD = 1.97), while the main sample included 879 students aged 18 to 23 years (M = 20.50, SD = 1.72). Both samples showed relatively balanced distributions across gender, residence location, and grade levels.

2.3. Measures

The Environmental Education Awareness Scale (EEAS) was employed to assess participants’ environmental awareness [53]. The scale comprises 13 items measured on a 5-point Likert scale ranging from 1 (Strongly Disagree) to 5 (Strongly Agree), with higher scores indicating greater EEA. The unidimensional structure of the scale was confirmed through confirmatory factor analysis (CFA) in the psychometric sample, demonstrating acceptable model fit indices: χ2/df = 3.846, goodness of fit index (GFI) = 0.933, adjusted goodness of fit index (AGFI) = 0.899, comparative fit index (CFI) = 0.918, Tucker–Lewis index (TLI) = 0.910, and root mean square error of approximation (RMSEA) = 0.077. Internal consistency reliability was excellent, with Cronbach’s alpha (α) of 0.871 and McDonald’s omega (ω) of 0.870 based on 614 valid cases.
The Revised Digital Citizenship Scale (DCS-R) was employed to assess participants’ digital citizenship competencies [54]. This instrument consists of 19 items distributed across four dimensions: Internet Political Activism (6 items), Technical Skills (3 items), Critical Perspectives (7 items), and Networking Agency (3 items). Responses were recorded on a 7-point Likert scale ranging from 1 (Strongly Disagree) to 7 (Strongly Agree). CFA demonstrated excellent model fit: χ2/df = 1.302, GFI = 0.969, AGFI = 0.960, CFI = 0.992, TLI = 0.991, and RMSEA = 0.022. Reliability coefficients for the subscales were strong: Internet Political Activism (α = 0.883, ω = 0.883), Technical Skills (α = 0.858, ω = 0.859), Critical Perspectives (α = 0.884, ω = 0.881), and Networking Agency (α = 0.871, ω = 0.871). The total scale demonstrated excellent internal consistency with α = 0.899 and ω = 0.889.
New General Self-Efficacy Scale (NGSE) was selected to assess participants’ generalized confidence in their capability to perform across achievement situations. While domain-specific environmental self-efficacy measures may yield stronger construct-specific associations, general self-efficacy was employed to capture broad confidence beliefs applicable across behavioral domains, including environmental action, consistent with the study’s exploratory mediation framework [55]. The scale consists of 8 items measured on a 5-point Likert scale ranging from 1 (Strongly Disagree) to 5 (Strongly Agree), with higher scores indicating greater general self-efficacy beliefs. Sample items include “I will be able to achieve most of the goals that I have set for myself” and “I believe I can succeed at most any endeavor to which I set my mind.” CFA supported the unidimensional structure of the scale with acceptable model fit indices: χ2/df = 4.450, GFI = 0.970, AGFI = 0.936, CFI = 0.950, TLI = 0.918, and RMSEA = 0.075. The scale demonstrated adequate internal consistency reliability with α = 0.790 and ω = 0.780, which are considered acceptable for an 8-item scale and consistent with values reported in previous validation studies.

2.4. Procedure

Data collection was conducted between 15 October 2025 and 29 October 2025, using a Google Forms questionnaire distributed electronically to participants. The questionnaire included demographic questions and three validated psychometric instruments measuring the study variables. Participants completed the survey at their convenience, with an average completion time of approximately 20 min. All responses were anonymous and confidential. Data screening procedures identified incomplete or invalid responses, resulting in the exclusion of 10 cases (1.6%) from the psychometric sample due to missing data.

2.5. Data Analysis

Data were analyzed using SPSS version 27 and AMOS version 26. Preliminary analyses included descriptive statistics, correlation analyses, and assessment of normality assumptions. To assess potential common method bias, Harman’s single-factor test was conducted, revealing that the first unrotated factor accounted for 30.676% of the total variance, well below the critical threshold of 50%. Pearson correlation coefficients were calculated to examine bivariate relationships among study variables. Mediation analysis was conducted using Hayes’ PROCESS macro (Model 4) with 5000 bootstrap samples to test the indirect effect of EEA on self-efficacy through digital citizenship. Bootstrap confidence intervals at the 95% level were computed to assess the significance of direct, indirect, and total effects. All statistical tests were two-tailed with significance at p < 0.05.

3. Results

Prior to testing the main hypotheses, preliminary analyses were conducted to examine the distributional properties of the study variables and assess the assumptions underlying the planned statistical analyses. All variables demonstrated acceptable ranges of skewness and kurtosis, indicating approximate normality of distributions. Descriptive statistics for the main sample (N = 879) are presented in Table 2, including means, standard deviations, and ranges for all study variables.
The means for all variables indicated generally positive responses across the sample. EEA demonstrated a mean of 44.57 (SD = 5.042), ranging from 36.00 to 60.00, suggesting moderately high awareness levels with adequate variability to support further analyses. Among the digital citizenship dimensions, Critical Perspectives showed the highest mean (M = 29.59, SD = 3.814), followed by Technical Skills (M = 17.31, SD = 1.296), Internet Political Activism (M = 17.24, SD = 3.929), and Networking Agency (M = 14.17, SD = 1.702). The total Digital Citizenship score averaged 78.33 (SD = 8.113), with observed scores ranging from 60.00 to 133.00, indicating substantial variability that supports correlational and mediational analyses. Self-efficacy scores demonstrated a mean of 29.78 (SD = 2.987), ranging from 24.00 to 40.00, suggesting that participants generally possessed moderately high confidence in their capabilities. Missing data analysis revealed minimal missing values (1.6% in the psychometric sample), which were handled through listwise deletion.
Pearson correlation coefficients were computed to examine the bivariate relationships among environmental education awareness, the four dimensions of digital citizenship, total digital citizenship, and self-efficacy. The correlation matrix is presented in Table 3. All correlations were statistically significant at p < 0.01, supporting the appropriateness of conducting mediation analyses.
EEA demonstrated strong positive correlations with self-efficacy (r = 0.756, p < 0.01) and total digital citizenship (r = 0.501, p < 0.01), indicating that students with higher environmental awareness tended to report greater self-efficacy beliefs and stronger digital citizenship competencies. Among the digital citizenship dimensions, Critical Perspectives showed the strongest correlation with EEA (r = 0.621, p < 0.01), followed by Internet Political Activism (r = 0.300, p < 0.01), Networking Agency (r = 0.193, p < 0.01), and Technical Skills (r = 0.143, p < 0.01). Digital citizenship (total) was also significantly correlated with self-efficacy (r = 0.627, p < 0.01), suggesting that digital competencies are associated with confidence in one’s capabilities. These patterns of relationships provided preliminary support for the hypothesized mediation model.
To test the mediating role of digital citizenship in the relationship between EEA and self-efficacy, Hayes’ PROCESS macro (Model 4) was employed with 5000 bootstrap samples. The analysis examined whether digital citizenship (M) mediated the effect of EEA (X) on self-efficacy (Y). The unstandardized and standardized regression coefficients, along with bootstrap confidence intervals, are presented in Table 4.
The results revealed that EEA significantly predicted digital citizenship (B = 0.806, SE = 0.047, β = 0.501, p < 0.001), indicating that a one-unit increase in environmental awareness was associated with a 0.806-unit increase in digital citizenship. The model predicting digital citizenship from environmental awareness accounted for 25.09% of the variance (R2 = 0.251, F(1, 877) = 293.778, p < 0.001). In the full mediation model predicting self-efficacy, both EEA (B = 0.350, SE = 0.014, β = 0.590, p < 0.001) and digital citizenship (B = 0.122, SE = 0.008, β = 0.331, p < 0.001) emerged as significant predictors. Together, these predictors explained 65.43% of the variance in self-efficacy (R2 = 0.654, F(2, 876) = 828.814, p < 0.001), indicating a substantial proportion of variance accounted for by the model. The decomposition of effects is presented in Table 5, which summarizes the total, direct, and indirect effects of EEA on self-efficacy through digital citizenship.
The total effect of EEA on self-efficacy was significant (B = 0.448, SE = 0.013, β = 0.756, p < 0.001, 95% CI [0.422, 0.474]), indicating that environmental awareness positively predicted self-efficacy when digital citizenship was not included in the model (R2 = 0.572, F(1, 877) = 1172.272, p < 0.001). The direct effect of EEA on self-efficacy remained significant after controlling for digital citizenship (B = 0.350, SE = 0.014, β = 0.590, p < 0.001, 95% CI [0.323, 0.376]), accounting for 78.1% of the total effect. Critically, the indirect effect through digital citizenship was statistically significant (B = 0.098, SE = 0.010, β = 0.166, 95% CI [0.079, 0.117]), as evidenced by the bootstrap confidence interval that did not include zero. This indirect effect accounted for 21.9% of the total effect, indicating that approximately one-fifth of the relationship between EEA and self-efficacy was mediated through digital citizenship competencies.
The conceptual model depicting the standardized path coefficients is illustrated in Figure 1. The figure shows the significant pathways from EEA to digital citizenship (β = 0.501, p < 0.001), from EEA to self-efficacy (β = 0.590, p < 0.001), and from digital citizenship to self-efficacy (β = 0.331, p < 0.001). The indirect pathway (β = 0.166) demonstrates the mediating mechanism through which environmental awareness influences self-efficacy via enhanced digital citizenship competencies.
These findings provide strong empirical support for the hypothesis that digital citizenship partially mediates the relationship between EEA and self-efficacy. While environmental awareness directly enhances self-efficacy beliefs, a significant portion of this relationship operates indirectly through the development of digital citizenship competencies, particularly through critical perspectives, technical skills, online political activism, and networking agency.

4. Discussion

The present study demonstrates that digital citizenship serves as a significant partial mediator in the relationship between EEA and self-efficacy, accounting for 21.9% of the total effect. This finding reveals that while environmental awareness directly strengthens individuals’ confidence in their capabilities (78.1% direct effect), digital competencies provide an additional pathway through which ecological knowledge translates into self-belief. Digital citizenship functions as a functional bridge, translating environmental knowledge into actionable confidence by equipping students with the practical digital repertoires necessary to move from awareness to agency. The strong correlation between Critical Perspectives and environmental awareness (r = 0.621) suggests that developing critical evaluation skills represents the primary mechanism linking environmental knowledge to digital citizenship. The mediating role of digital citizenship indicates that students who possess environmental awareness can leverage digital tools, online activism platforms, and networking capabilities to transform abstract knowledge into concrete action repertoires, thereby enhancing their perceived capacity as environmental agents capable of meaningful contributions.
The findings can be further understood in light of the theoretical nature of each model construct. EEA operates across three interrelated levels: cognitive (knowledge of environmental issues), affective (emotional concern toward the environment), and behavioral intention (motivation to engage in pro-environmental action), with the translation across these levels being neither automatic nor guaranteed—a gap this study empirically confirms. Digital citizenship, operationalized across Internet Political Activism, Technical Skills, Critical Perspectives, and Networking Agency, extends beyond passive technology use toward active, critically informed civic participation, providing the practical repertoires necessary to bridge this gap. General self-efficacy, shaped by mastery experiences, vicarious learning, verbal persuasion, and physiological states, represents the ultimate psychological outcome through which EEA and digital citizenship collectively manifest as confident environmental agency.
These findings align with established literature demonstrating that environmental self-efficacy mediates the knowledge–action gap, converting awareness into behavior [16,23,24]. However, this study extends existing research by identifying digital citizenship as a novel mediating mechanism not previously examined in environmental contexts. The results support assertions that digital competencies facilitate mastery experiences—the strongest source of self-efficacy—by enabling students to create advocacy campaigns and collaborative projects [31,32]. Consistent with findings that digital skills reduce cognitive strain and enhance domain-specific self-efficacy [33,34,35], our results suggest digital citizenship operationalizes environmental awareness into self-belief. This integration addresses the critical gap where digital technologies were treated as neutral delivery mechanisms rather than civic competencies bridging awareness and efficacy [24,49].
The findings carry significant implications for advancing Sustainable Development Goals, particularly SDG 4.7 (education for sustainable development) and SDG 13 (climate action). Educational institutions should intentionally integrate digital citizenship training within environmental curricula, recognizing that technical skills, critical perspectives, and online activism competencies serve as “smart tools” enabling students to externalize ecological knowledge [28]. The strong mediating role of Critical Perspectives suggests that teaching students to critically evaluate digital information about environmental issues represents a high-leverage intervention point. Educators should design learning experiences that combine environmental content with opportunities for digital advocacy, online collaboration, and technology-enhanced storytelling, thereby building both green minds and the digital capabilities necessary to translate awareness into confident environmental action. This integrated approach directly supports climate-literate citizenship capable of informed mitigation behaviors [37,38].
Several limitations warrant consideration when interpreting these findings. The cross-sectional design precludes causal inference, as reciprocal relationships may exist whereby self-efficacy enhances environmental awareness or digital citizenship. As data were collected at a single timepoint, observed relationships reflect associations rather than directional causality; longitudinal and experimental designs are required to establish temporal precedence among study variables. The convenience sample drawn exclusively from Egyptian university students limits generalizability across cultural contexts, educational levels, and age groups. Restriction to a single national and institutional context constrains transferability to populations differing in digital infrastructure, environmental policy landscape, or educational tradition, necessitating cross-cultural replication before broader conclusions are warranted.
The reliance on self-report measures introduces potential common method bias, though Harman’s test suggested this was not problematic. Self-reported data remain susceptible to social desirability bias; future research should incorporate behavioral measures or multi-informant designs to enhance construct validity and response accuracy. The study employed general self-efficacy rather than domain-specific environmental self-efficacy, which may have underestimated the strength of relationships given that specialized measures typically demonstrate stronger associations with related constructs. Employing a domain-specific environmental self-efficacy instrument would yield more precise effect estimates and stronger ecological validity in future investigations. Future research should address these limitations through longitudinal designs, diverse samples, multi-method assessments, and environmental-specific efficacy measures to strengthen causal claims and ecological validity.
Although digital citizenship was operationalized as a composite variable, disaggregating its four dimensions as independent mediators in future analyses would identify which specific competencies most efficiently facilitate the awareness-to-efficacy translation, enabling more targeted pedagogical interventions. Future investigations should employ longitudinal and experimental designs to establish temporal precedence and causal relationships among environmental awareness, digital citizenship, and self-efficacy. Researchers should examine whether domain-specific environmental self-efficacy demonstrates stronger mediation patterns than general self-efficacy, potentially revealing distinct pathways for different environmental behaviors (climate advocacy versus conservation actions). Cross-cultural studies comparing digital citizenship’s mediating role across Global North and South contexts would illuminate how technological access and digital infrastructure moderate these relationships. Intervention studies testing integrated environmental-digital curricula could provide practical evidence for optimal pedagogical approaches. Finally, researchers should investigate which specific digital citizenship dimensions (critical perspectives, technical skills, activism, networking) exert the strongest mediating effects, enabling targeted educational interventions that maximize the transformation of environmental awareness into confident, sustained climate action across diverse populations and educational contexts.

5. Conclusions

This study provides empirical evidence that digital citizenship serves as a critical mediating mechanism through which EEA translates into self-efficacy, thereby integrating “green minds” with “smart tools.” The findings reveal that approximately one-fifth of environmental awareness’s effect on self-efficacy operates through digital competencies, suggesting that ecological knowledge alone is insufficient without accompanying digital literacy, critical evaluation skills, and online civic participation. By identifying digital citizenship as the bridge spanning the knowledge–action gap, this research advances theoretical understanding of how 21st-century competencies enable confident environmental action. The results underscore the necessity of integrated educational approaches that combine environmental content with digital skill development to cultivate climate-literate, digitally empowered citizens capable of meaningful contributions to global sustainability challenges and climate stabilization efforts. Critically, the findings affirm that environmental education curricula must be redesigned to incorporate digital citizenship training, ensuring students develop not only green minds but also the digital empowerment necessary to act meaningfully on that knowledge in real-world contexts.
