The study set out to answer a question that has lingered in environmental psychology and urban policy circles: do participation and responsibility work together to produce greener citizens, or do they operate on separate tracks? Most prior research has treated these two constructs separately. A large body of work built on the Theory of Planned Behavior, one of the most widely used frameworks in environmental psychology, holds that behavior flows from intentions, which in turn are shaped by attitudes, subjective norms, and perceived behavioral control. Participation has often been assumed to strengthen these ingredients by giving people a stake in outcomes. Responsibility, meanwhile, has been studied mostly in the context of prosocial behavior, where a felt obligation to others motivates action even when personal benefit is absent.

Hamidi’s approach was to bring both constructs into a single theoretical framework and test them simultaneously. The research adopted a quantitative design centered on a survey of 385 citizens in Tehran, a metropolis governed through a highly centralized urban management structure in which major environmental decisions are made by municipal and state authorities rather than through deliberative local processes. Respondents answered questionnaire items measuring their levels of citizen participation, civic responsibility, and social responsibility, alongside measures of their pro-environmental behavior. The data were then analyzed using partial least squares structural equation modeling, or PLS-SEM, a statistical technique that allows researchers to test whether hypothesized causal pathways between multiple variables are supported by observed data.

Structural equation modeling works by estimating latent variables, which are constructs such as responsibility or participation that cannot be observed directly but are inferred from multiple survey responses. The model then evaluates the strength and statistical significance of paths linking these latent variables to one another. In this study, the model tested both direct effects, such as the path from civic responsibility to pro-environmental behavior, and indirect effects, in which one variable might influence behavior through another. This dual testing matters, because a variable can fail to influence behavior directly while still shaping it indirectly through mediating factors. If participation mattered at all, even indirectly, the model should have detected it.

The results were unambiguous on one side and surprising on the other. Both civic responsibility, which refers to a person’s sense of duty toward their community and its shared spaces, and social responsibility, the broader felt obligation toward society and collective welfare, exerted significant positive effects on pro-environmental behavior. Citizens who felt responsible for the wellbeing of their city and their fellow residents were measurably more likely to act in environmentally friendly ways. Citizen participation, by contrast, showed no meaningful direct or indirect influence on behavior. In other words, it was not simply that participation failed to act on behavior directly while working through responsibility; the analysis found no significant pathway from participation to behavior at all.

Why would participation prove so inert in this context? The author’s interpretation points to the governance environment itself. In centralized systems, participatory opportunities often exist in form but carry little substantive weight. Public consultations may occur after decisions have effectively been made, and residents may perceive that their input does not alter outcomes. Under such conditions, the psychological mechanism that participation is supposed to activate, a sense of ownership and control over collective decisions, never engages. The study’s conclusion is that the behavioral relevance of participation is context-dependent rather than universally positive, a claim that directly challenges the tendency to export participation-based interventions from decentralized democracies to cities with very different administrative structures.

The theoretical contribution lies in how the study extends the Theory of Planned Behavior. Rather than discarding the framework, the research positions civic and social responsibility as complementary motivational mechanisms that operate alongside the conventional pathways of attitude, norm, and perceived control. This matters because the TPB has been criticized for explaining intentions better than actual behavior, and for performing inconsistently across cultures. By demonstrating that responsibility-based constructs can carry substantial explanatory weight in a centralized governance context, the study suggests that behavioral models of environmental action need to be calibrated to institutional realities. A theory validated in participatory settings may systematically misidentify the levers that matter in settings where citizens have limited decision-making power.

For policymakers, the practical message is a reframing of priorities rather than a rejection of participation. The study does not argue that participatory initiatives are worthless; it argues that, on their own and under centralized governance, they do not translate into environmental action. Instead, the findings indicate that governments and urban managers should complement participatory programs with strategies that actively cultivate civic and social responsibility. That could mean educational campaigns that frame environmental action as a duty to neighbors and future residents, neighborhood-level recognition of stewardship, or communication strategies that emphasize collective obligation rather than individual choice. The underlying logic is that motivation must be built where the behavioral leverage actually lies.

The choice of Tehran gives the findings particular weight. Megacities in centralized governance systems face some of the world’s most severe environmental pressures, from air pollution to water stress, and their governments often lack the fiscal and institutional capacity to solve these problems top-down. If individual behavior change is to contribute at all, understanding what motivates it becomes essential. A survey of 385 residents, analyzed with a method designed to test competing causal pathways, offers a template for how such questions can be answered empirically rather than ideologically. The same design could be replicated in other centralized cities to test whether the responsibility effect is a general feature of such systems or specific to Tehran’s circumstances.

There are, of course, limits to what a single cross-sectional survey can establish. Structural equation modeling tests whether data are consistent with a hypothesized causal structure, but it cannot prove causation in the way an experiment can, and self-reported behavior may diverge from what people actually do. The study also received no external funding, and the author declares no competing interests, which strengthens confidence in its independence. Even with these caveats, the central result stands as a provocative datapoint in a debate that usually assumes more participation means more environmental action. In Tehran at least, the greener citizen is not the one who shows up to meetings, but the one who feels personally responsible for the city they share. For urban managers everywhere, that distinction may be the most important finding of all.

The Inventory of Climate Emotions, known in the literature as the ICE, is a multidimensional self-report instrument that distinguishes itself from narrower measures of climate distress. Rather than collapsing all climate-related feeling into a single index of anxiety or worry, the inventory maps nine to eight separate emotional response families — including anger, fear, sadness, guilt, contempt, hope, fascination and awe-related content — capturing the genuine complexity of how individuals relate to a changing planet. This granularity matters scientifically because different emotions predict different outcomes: guilt and anger often fuel pro-environmental activism, hope sustains engagement over time, and fear or sadness correlate more closely with psychological burden. A country lacking a validated version of such an instrument, the authors argue, is effectively locked out of both international comparisons and precise local research on the mental health consequences of environmental change.

The research team set out to translate and culturally adapt the measure for Ukrainian respondents, a process that requires far more than literal word-for-word conversion. Emotional terms do not map neatly across languages, and items describing, for example, guilt about consumption or awe at nature must resonate with the lived experience of the target population. The researchers then administered the adapted Ukrainian version, designated the ICE-UA, together with a battery of other validated psychological measures to 673 Ukrainian adults recruited through an online survey. The sample had a mean age of 36.13 years with a standard deviation of 11.37, and women made up 67.2 percent of respondents. Alongside the climate emotion items, participants completed instruments assessing eco-anxiety, environmental attitudes and behavior, depressive symptoms, and subjective well-being, allowing the team to test whether the new scale behaved the way theory says it should.

The statistical centerpiece of the study was confirmatory factor analysis, a technique that tests whether the pattern of relationships among questionnaire items matches a predefined structure — in this case, the eight-factor architecture of the original inventory. The results were strong: the comparative fit index reached 0.947 and the Tucker-Lewis index 0.939, both comfortably above conventional thresholds, while the root mean square error of approximation stood at 0.079 and the standardized root mean square residual at 0.057, values that fall within acceptable bounds for psychological measurement models. Internal consistency, assessed with McDonald’s omega, ranged from 0.786 to 0.912 across the eight subscales, indicating that the items within each emotional dimension cohere tightly enough to yield dependable scores.

Perhaps the most technically ambitious component was the analysis of measurement invariance, the property that determines whether a scale measures the same underlying constructs in the same way across different groups. Using multi-group confirmatory factor analysis, the researchers compared configural, metric, and scalar levels of invariance across gender, age groups, displacement status, and — strikingly — across two independent data collection waves conducted in 2024 and 2025. Full measurement invariance was established in every comparison, meaning that a given score on, say, the fear or hope subscale carries the same psychological meaning for a displaced respondent as for someone who stayed home, for a woman as for a man, and for someone surveyed in the third year of the full-scale invasion as for someone surveyed in the fourth.

This wartime setting is what elevates the study from routine psychometrics to something genuinely novel. Climate emotion research typically proceeds in relatively stable societies, where the dominant stressors are economic or political. Ukrainian respondents completed the ICE-UA while managing the chronic stress of armed conflict, a context that plausibly competes with or reorganizes environmental concerns. That the eight-factor structure not only survived but proved fully comparable across independent wartime samples collected a year apart suggests the underlying emotional architecture of climate response is robust to extraordinary contextual strain. The authors note that this comparability across waves provides further structural support for the inventory itself, beyond its specific Ukrainian application.

Nomological validity — the demonstration that a measure relates to other constructs in theoretically expected ways — was examined using Spearman’s rank correlations, a non-parametric approach appropriate for the response distributions involved, with Benjamini-Hochberg correction applied to control the false discovery rate. Climate emotions on the ICE-UA showed significant associations with eco-anxiety as measured by the Hogg Eco-Anxiety Scale, with environmental attitudes and pro-environmental behavior, with depressive symptoms, and with subjective well-being as captured by the WHO-5 Well-Being Index. These relationships followed the expected directional pattern, reinforcing the interpretation that the scale taps genuine affective dispositions rather than statistical artifacts, and confirming its usefulness for studies linking climate affect to mental health and environmental action.

Group differences emerged that echo patterns seen in prior international research. Women scored higher than men on most of the emotion subscales, a finding consistent with broader evidence that women on average report more intense emotional responses to climate change. Men, by contrast, scored higher on the contempt dimension, an intriguing result given that contempt toward climate discourse or climate actors is among the least studied emotions in the environmental psychology repertoire. Multiple linear regression was used to test these differences while accounting for age, study wave, and displacement status, and the fact that such differences were detectable at all is itself evidence of the scale’s sensitivity: a poorly performing instrument would show floor effects or noise rather than orderly, theory-consistent demographic contrasts.

For researchers and clinicians, the practical consequences are immediate. Ukrainian-speaking populations can now be assessed with a multidimensional climate emotion instrument whose scores are comparable across gender, age, displacement, and time — a property that opens the door to longitudinal studies tracking how climate feelings evolve as the war continues and as environmental pressures accumulate. The validated ICE-UA also enables cross-cultural research comparing Ukraine with the growing family of countries where the inventory has been adapted, testing whether the emotional geography of the climate crisis is universal or shaped by national circumstance. The study, ethically approved by the Institutional Ethics Committee of V.N. Karazin Kharkiv National University and conducted under the Declaration of Helsinki, received no external funding, and the authors report no competing interests. As climate change intensifies and as psychological research increasingly treats emotional response as a key driver of both environmental behavior and mental health, the Ukrainian validation stands as evidence that even a society under bombardment can contribute rigorous, internationally comparable data on how humanity feels about a warming world.

The concept at the heart of the study is eco-anxiety: the chronic emotional distress that arises from concern about climate change and environmental degradation. Unlike a clinical phobia, eco-anxiety is generally understood as a rational response to a real threat, but its intensity varies enormously from person to person, and its relationship to behavior has proven stubbornly difficult to pin down. Earlier work, including the development of the Hogg eco-anxiety scale and the climate change anxiety measure by Susan Clayton and Bryan Karazsia, has established that eco-anxiety is multidimensional, encompassing affective symptoms, rumination, behavioral disruption and anxiety about one’s own ecological impact. What has remained unclear is how these feelings map onto the everyday, consumption-related choices that ultimately determine an individual’s carbon footprint.

To probe that connection, the Castilla-La Mancha team applied a deliberately multidimensional framework. They surveyed adolescents across the region and measured not only eco-anxiety but also a battery of socioeconomic and sociodemographic characteristics, psychosocial variables — most importantly, the degree to which respondents include nature in their sense of self — and pro-environmental behaviors defined as consumption-related practices with measurable climate change mitigation potential. The analytical toolkit combined multiple linear regression, which allowed the researchers to isolate the independent contribution of each factor to eco-anxiety scores, with correspondence analyses, a technique well suited to uncovering behavioral profiles and associations among categorical variables.

The regression results are striking in their clarity. Eco-anxiety was significantly associated with sociodemographic variables, most notably gender, echoing a broad international literature showing that girls and young women consistently report higher levels of climate concern and climate-related distress than their male peers. It was also strongly linked to connection with nature: adolescents who described themselves as psychologically intertwined with the natural world — a construct operationalized through measures of inclusion of nature in the self, following the connectedness-to-n tradition pioneered by F. Stephan Mayer and Cynthia McPherson Frantz — reported markedly higher eco-anxiety. In other words, the more a teenager sees nature as part of who they are, the more they suffer when that nature appears threatened.

But the study’s most consequential finding concerns behavior, and it cuts against the intuitive assumption that anxiety and action go hand in hand. The researchers found a sharp divergence between two facets of pro-environmental engagement. Adolescents who actually performed mitigation-related practices — the concrete, consumption-linked behaviors that carry genuine climate mitigation potential — reported lower levels of eco-anxiety. Adolescents who expressed a strong willingness to act but had not yet converted that intention into practice reported higher eco-anxiety. Actual mitigation, in short, appears to soothe; mere willingness appears to gnaw. The authors interpret this as evidence of a psychological gap between intention and action, in which unresolved intention becomes itself a source of distress, while completed behavior restores a sense of agency and coherence.

Using the correspondence analysis, the team identified four distinct behavioral profiles among the adolescents, and each tells a different story about environmental commitment in the climate crisis era. The first group, labeled “involved,” combines high eco-anxiety with strong behavioral engagement — young people who worry intensely and act accordingly. The second, “content,” consists of adolescents who appear satisfied with their current behaviors, achieving a kind of equilibrium between effort and reassurance. The third, “willing,” is the group that embodies the intention-action gap: high willingness, unresolved distress, limited actual practice. The fourth, “disengaged,” shows both low engagement and low eco-anxiety — teenagers who are neither acting nor particularly worried, a pattern the authors implicitly flag as fragile, because it may reflect psychological distancing from a problem that will not go away.

This four-profile typology matters because it demonstrates that pro-environmental commitment cannot be captured by any single indicator. A survey that asked only “how willing are you to act?” would conflate the involved and willing groups, treating a teenagers’ stated intentions as equivalent to their lived behavior. A survey that measured only current behavior would miss the distress brewing in the willing group. By examining patterns rather than points, the Castilla-La Mancha researchers reveal a heterogeneous landscape in which adolescents occupy qualitatively different relationships to the climate crisis — some anxious and active, some anxious and frozen, some calm and committed, some simply absent from the conversation.

The regional setting lends the findings particular weight. Castilla-La Mancha is one of Spain’s most depopulated regions, a territory of dispersed settlements and long travel distances whose per-capita carbon footprint has been the subject of sustained economic research by the same university community, including analyses of household emissions, carbon taxation vulnerability and the so-called “empty Spain.” Previous work by co-authors affiliated with the Universidad de Castilla-La Mancha has documented gender differences in household carbon footprints in Spain and quantified the mitigation potential of consumption options across European contexts. Placing adolescent eco-anxiety within this regional economic reality connects the psychological to the material: young people in rural and semi-rural Spain are forming their environmental identities in a place where low-carbon living is structurally harder, not easier.

The study also carries practical implications for educators, clinicians and policymakers. If willingness without action is itself a driver of distress, then environmental education that stops at raising awareness may inadvertently intensify eco-anxiety rather than relieve it. The findings suggest that interventions should be designed to help adolescents close the intention-action gap — providing concrete, achievable mitigation practices that convert worry into efficacy. Conversely, the low-anxiety, low-engagement disengaged profile warns against complacency: silence about climate is not the same as resilience. The authors note that their survey data contain sensitive information and can be shared only under well-founded request and after anonymization, underscoring the care required when researching minors’ mental health. The work was funded by the Regional Government of Castilla-La Mancha and approved by the university’s Social Research Ethics Committee.

As climate change accelerates, the inner lives of adolescents are becoming a legitimate barometer of the crisis. This study shows that barometer is reading high in some quarters, low in others, and that the relationship between what young people feel and what they do is neither simple nor stable. Eco-anxiety, the research suggests, is not a fixed pathology but a signal — amplified by connection to nature and by unfulfilled intentions, dampened by real action — and understanding its behavioral geography among the young may prove essential to sustaining both their mental health and the environmental commitment the coming decades will demand of them.

The research team, led by Chenxin Leng of Beijing University of Chemical Technology and Zhongkun Zhu of Beijing Institute of Technology, analyzed pooled data from the 2019 and 2021 waves of the Chinese Social Survey, yielding 9,768 observations. Their central question was deceptively simple: does a rural resident’s self-reported well-being predict whether they engage in environmentally responsible actions? But answering it credibly required confronting a stubborn methodological obstacle. Well-being and environmental behavior could be linked in either direction—happier people may act greener, but greener lifestyles may also make people happier—and unmeasured factors such as personality or local culture could distort the apparent relationship.

To untangle this knot, the authors deployed a two-stage residual inclusion approach, a technique designed to address potential endogeneity bias in non-linear models. In practical terms, the method first models the determinants of subjective well-being, extracts the residual variation, and then incorporates that residual into the behavioral equation, allowing the researchers to isolate the effect of well-being itself rather than the effect of confounding characteristics. This is a more demanding standard than the simple correlations that dominate much of the environmental psychology literature, and it is precisely what gives the new findings their weight.

The results were striking. Subjective well-being significantly enhanced pro-environmental behaviors, and the effect survived a battery of robustness checks. The team substituted alternative estimation methods, including control function and combined model estimates, and re-ran the analysis on an entirely different dataset, the 2013 Chinese General Social Survey, which captures ten distinct types of pro-environmental behavior. They also performed omitted variable tests to probe whether unobserved factors could plausibly explain away the association. Across all of these stress tests, the core conclusion held: happier rural residents do more for the environment.

But the study goes beyond establishing that a link exists; it probes how the link operates. The researchers examined three candidate mechanisms: environmental concern, income status expectations, and social trust. All three partially mediated the relationship between well-being and green behavior. In other words, people who feel better about their lives tend to worry more about environmental problems, to expect their economic standing to improve, and to trust others more—and each of these psychological states, in turn, encourages environmentally responsible action. The authors describe these as cognitive and relational pathways: the first two channels operate through how people think about the future and the natural world, while social trust operates through the quality of relationships within the community.

This mediating architecture has important theoretical implications. Environmental concern has long been treated as the primary psychological gateway to green behavior, but the new evidence suggests that well-being feeds into environmental action through a broader portfolio of dispositions. Optimism about one’s income trajectory may reduce the perceived trade-off between personal sacrifice and environmental protection, while trust lowers the fear of being exploited as a cooperator in situations where collective action is required. Together, these channels help explain why well-being matters even for behaviors that carry no immediate personal reward.

The heterogeneity analyses add further nuance. The well-being effect was particularly strong among middle-aged and elderly residents, among males, and among highly educated individuals. Perhaps most intriguingly, the study found that subjective well-being exerted a stronger influence on public-sphere pro-environmental behaviors—actions such as participating in community environmental initiatives or advocating for environmental protection—than on private-sphere behaviors like household energy saving or waste sorting. Public-sphere actions depend heavily on social engagement and confidence, which may explain why they respond more sensitively to psychological flourishing than private, routine behaviors do.

One of the most consequential findings concerns the rural-urban divide. When the researchers ran parallel analyses on urban residents, they discovered that rural residents demonstrated greater well-driven behavioral change than their urban counterparts. The authors attribute this to stronger community ties in rural areas, where dense social networks and long-standing relationships amplify the trust pathway through which well-being operates. In villages where neighbors know one another, a person’s sense of well-being appears to ripple outward into collective environmental engagement more readily than in the more anonymous settings of Chinese cities. This suggests that the countryside, often treated as a laggard in environmental policy, may actually be fertile ground for well-being-based interventions.

The policy implications are considerable. Traditional environmental campaigns rely on regulation, subsidies, or information provision, all of which can be expensive or difficult to enforce at scale. The new study points toward a complementary strategy: integrate mental health promotion with environmental education, income support, and community trust-building. If happiness, optimism, and trust jointly fuel green behavior, then investments in rural psychological services, social insurance, and local civic life may pay a double dividend—improving quality of life while simultaneously advancing sustainability goals. The authors specifically highlight the promise of fostering public-sphere environmental engagement in rural areas, where the well-being effect is strongest.

Caveats remain, as they do in any observational study. The data are self-reported, and the survey design, while rich, cannot fully rule out every conceivable confounder. The two-stage residual inclusion approach and the extensive robustness checks mitigate but do not eliminate concerns about causality, and the Chinese context—rapid rural transformation, strong state-led environmental campaigns, distinctive village social structures—may limit generalizability to other countries. Still, the convergence of evidence across two national surveys, multiple estimation strategies, and clearly articulated mechanisms makes this one of the most rigorous examinations to date of the well-being–environment link in a developing-country rural setting. As governments grapple with how to mobilize citizens for environmental action, the message from rural China is quietly radical: people who feel good do good, and policies that cultivate well-being may be among the most underrated tools for building a sustainable future.

The stakes could hardly be higher. Secondary school learners occupy a pivotal developmental window during which values, attitudes, and lifelong habits take root. At this stage of adolescence, students develop the abstract reasoning, ethical judgment, and sense of social responsibility that complex environmental issues demand. International frameworks, including Sustainable Development Goal 4.7 and UNESCO’s Education for Sustainable Development agenda, explicitly call for education systems to move beyond knowledge transmission toward transformative learning. When environmental education is intentionally integrated into secondary curricula, the review argues, it can cultivate the critical thinking, systems thinking, and problem-solving skills that empower young people to engage with environmental challenges at local, national, and global scales. But the authors found that in many African contexts this potential remains largely unrealized, with environmental concepts often treated as peripheral add-ons rather than core learning priorities.

The research team, led by Victor Okoth Saoke of the University of Embu in Kenya alongside colleagues at the University of Embu and the University of Hail in Saudi Arabia, conducted an extensive search across Scopus, Web of Science, Google Scholar, and African Journals Online, supplemented by grey literature from UNESCO, UNEP, the World Bank, and FAO. From an initial pool of 672 records, rigorous screening narrowed the field to 22 studies meeting strict eligibility criteria, including empirical designs, African secondary school settings, and clear focus on curriculum integration, pedagogy, learner outcomes, or institutional factors. Quality was assessed using the Mixed Methods Appraisal Tool for empirical studies and the AACODS checklist for grey literature. The methodological landscape of the included research was diverse: twelve systematic reviews, four qualitative investigations, two mixed-methods studies, two policy analyses, and two quasi-experimental studies, with geographic coverage spanning Ethiopia, Nigeria, Tanzania, South Africa, and beyond.

Three dominant models of curriculum integration emerged from the synthesis. The infusion model, the most common entry point, embeds environmental concepts across existing subjects such as biology, geography, agriculture, and social studies. When executed intentionally, infusion fosters interdisciplinary thinking, allowing a single phenomenon like river ecology to be examined through hydrology, land-use economics, and civic responsibility simultaneously. The review found this approach particularly pragmatic in resource-constrained systems where adding new subjects is politically or financially difficult. However, without careful curriculum mapping and explicit learning outcomes, infusion degrades into a disjointed series of mentions, and teachers facing heavy examination pressure routinely sideline environmental content that is not assessed.

Stand-alone environmental science subjects offer a contrasting model with distinct advantages. By dedicating timetable space to sustained inquiry, fieldwork, and project-based assessment, well-designed stand-alone courses can produce deeper conceptual understanding and more robust competency development. Naming a subject as environmental science also carries symbolic weight, signaling institutional priority and legitimizing investment in specialist teachers and materials. Yet the review cautions that stand-alone subjects are not a panacea. In crowded timetables and under-resourced contexts, they often become electives restricted to better-funded schools, reproducing equity gaps in environmental literacy. The third model, whole-school approaches, treats sustainability as a school-wide enterprise spanning curricula, management routines, student eco-committees, gardens, waste management, and community partnerships. Global programs such as Eco-Schools exemplify this strategy, and evidence shows substantial gains in learner attitudes, leadership, and everyday sustainable practices because environmental responsibility becomes a lived habit rather than a one-off lesson.

Pedagogy emerged as at least as important as curriculum placement. The literature converges on a clear finding: experiential, outdoor, and inquiry-based teaching methods consistently outperform didactic, lecture-based instruction in strengthening environmental knowledge, attitudes, and behaviors. Experiential learning grounded in activities such as water-quality testing, biodiversity surveys, and school waste audits deepens retention and strengthens the affective attachment to nature that predicts conservation behavior, provided hands-on activity is paired with structured reflection. Outdoor and place-based learning enhances cognitive, social, and emotional outcomes simultaneously, fostering connectedness to nature, a psychological construct strongly associated with pro-environmental attitudes. Problem-based learning reframes environmental topics around authentic local dilemmas, from polluted rivers to groundwater scarcity, cultivating the systems thinking and collaboration needed for sustainability-oriented citizenship. Service learning and school-community projects add a civic dimension, giving students real-world experience of environmental action and its consequences.

The impact on learners follows a consistent but uneven pattern. Environmental knowledge gains are robust and well-documented across study designs, with meta-analytic evidence confirming significant short-term improvements in understanding of ecosystems, climate change, and conservation practice. Attitudinal shifts, including greater care for nature and stronger environmental values, are also widely reported, particularly in programs using experiential and participatory pedagogies such as fieldwork, citizen science, and service learning. Behavioral outcomes, however, are the most contested. Some school and community programs report meaningful increases in recycling, energy conservation, and tree planting, while other evaluations find modest or statistically insignificant effects, especially for behaviors requiring sustained effort or structural support. Self-reported measures frequently inflate estimates compared with observed behaviors, and evidence for long-term retention of both knowledge and attitudes remains thin due to short follow-up periods.

The review identifies a cluster of structural barriers that repeatedly undermine implementation. Teacher preparedness stands out as a central constraint: many secondary school teachers lack formal training in environmental education or education for sustainable development, limiting their confidence and capacity to integrate environmental concepts into subject teaching. Curriculum overload compounds the problem, as examination-oriented systems push teachers to prioritize assessed content over cross-cutting themes. Resource constraints further limit experiential approaches, with many schools lacking teaching materials, laboratory facilities, outdoor learning spaces, and community partnerships. Weak assessment frameworks reduce accountability, making it difficult to evaluate whether environmental education actually influences learner behavior. The authors also flag equity concerns, noting that high-quality environmental education experiences are disproportionately available to better-resourced schools, risking a widening of existing educational inequalities unless policy deliberately prioritizes low-cost, high-impact interventions and scalable teacher training.

Despite these challenges, the review’s conclusions are constructive. Environmental education holds substantial promise as a transformative force in secondary schooling, but realizing it demands coherent, system-wide effort. The authors advocate hybrid strategies that combine infusion across all classrooms, targeted stand-alone courses for depth and specialist skills, and whole-school programs that cultivate habits and agency, all supported by sustained teacher professional development, community partnerships, and assessment reform that rewards inquiry, practical skills, and civic action. Programs addressing psychological mediators such as environmental identity, self-efficacy, and social norms show the strongest behavioral benefits. The review also highlights a critical research gap: longitudinal, context-sensitive studies tracking how school-based environmental education shapes learners’ trajectories into adulthood remain scarce, and the authors call for mixed-methods, multi-level designs capable of demonstrating lasting impact. Bridging the persistent gap between policy aspiration and classroom reality, the study concludes, is the decisive task if African secondary schools are to produce a generation equipped not merely to understand the environmental crisis but to act upon it.

The review’s methodological transparency reflects broader shifts in how education evidence is produced and trusted. By following PRISMA reporting standards, the authors made their search strings, eligibility decisions, and appraisal steps auditable, which matters in a field where advocacy often outruns evidence. The inclusion of policy documents alongside empirical studies is also notable, since it allowed the team to compare what governments promise on paper with what classrooms actually deliver, a comparison that proved central to their diagnosis of implementation gaps.

One underappreciated dimension of the findings concerns measurement itself. Because most behavioral outcomes in the included studies relied on learner self-reports, the true effect of school programs on everyday practices such as waste sorting or water conservation remains uncertain. The authors’ call for observational designs and longer follow-up periods echoes a wider concern in environmental psychology, where the link between stated intentions and sustained behavior is known to be fragile. Studies that track learners beyond graduation, into household and community settings, would provide far stronger evidence of whether secondary schooling produces durable environmental citizens.

Geographic coverage also deserves scrutiny. The included studies clustered in a handful of countries, leaving large parts of the continent, particularly Francophone and Lusophone Africa, thinly represented in the evidence base. This unevenness limits the generalizability of the synthesis and means curriculum reforms in many nations are proceeding without locally relevant research. The authors suggest that investment in African education research capacity, including support for local journals and open-access publication, would help close this gap.

Finally, the review’s emphasis on psychological mediators such as connectedness to nature and self-efficacy offers a practical lever for designers. Programs that deliberately build emotional bonds with local environments, rather than transmitting facts alone, appear most likely to convert classroom learning into lifelong stewardship.
