Field interventions for climate change mitigation behaviors: A second-order meta-analysis.

Behavioral change is essential to mitigate climate change. To advance current knowledge, we synthesize research on interventions aiming to promote climate change mitigation behaviors in field settings. In a preregistered second-order meta-analysis, we assess the overall effect of 10 meta-analyses, incorporating a total of 430 primary studies. In addition, we assess subgroup analyses for six types of interventions, five behaviors, and three publication bias adjustments. Results showed that climate change mitigation interventions were generally effective (dunadjusted = 0.31, 95% CI [0.30, 0.32]). A follow-up analysis using only unique primary studies, adjusted for publication bias, provides a more conservative overall estimate (d = 0.18, 95% CI [0.13, 0.24]). This translates into a mean treatment effect of 7 percentage points. Furthermore, in a subsample of adequately powered large-scale interventions (n > 9,000, k = 32), the effect was adjusted downward to approximately 2 percentage points. This discrepancy might be because large-scale interventions often target nonvoluntary participants by less direct techniques (e.g., "home energy reports") while small-scale interventions often target voluntary participants by more direct techniques (e.g., face-to-face interactions). Subgroup analyses showed that interventions based on social comparisons or financial incentives were the most effective, while education or feedback was the least effective. These results provide a comprehensive state-of-the-art summary of climate change mitigation interventions, guiding both future research and practice.

Feeling anxious and being engaged in a warming world: climate anxiety and adolescents' pro-environmental behavior.

BACKGROUND: Climate anxiety is increasingly prevalent among adolescents worldwide. Are climate-anxious adolescents prone to engage in pro-environmental behavior? Or might the association between climate anxiety and pro-environmental be curvilinear, such that high levels of climate anxiety become 'paralyzing'? And do these associations depend on whether adolescents believe that, with effort, the worst impacts of climate change can still be prevented? METHODS: We addressed these questions in three studies (two preregistered; combined N = 2,211), conducted across two countries. We used cross-sectional and longitudinal methods, and various measures of climate anxiety and pro-environmental behavior. We performed Bayesian regression analyses comparing two models that tested competing hypotheses. The first model included a linear effect of climate anxiety on pro-environmental behavior, and the second model included both a linear and a curvilinear (i.e. inverted U-shaped) effect of climate anxiety on pro-environmental behavior. Next, we added environmental efficacy to the best fitting model and explored its moderating effects. RESULTS: Adolescents reported low-to-moderate levels of climate anxiety. Across the board, we found evidence for a small, positive, and mostly linear (rather than curvilinear) association between climate anxiety and pro-environmental behavior. While Study 1 supported a curvilinear association (Bayes Factor (BF) = 18.87), Studies 2 and 3 mostly supported a linear model (BFs range 6.86-12.71), except for weak support (BF = 1.62) for a curvilinear association between climate anxiety symptoms and public sphere pro-environmental behavior. Adolescents' environmental efficacy moderated this link for public sphere (e.g. activism), but not private sphere (e.g. recycling), pro-environmental behavior. CONCLUSIONS: Climate-anxious adolescents are prone to engage in pro-environmental behavior. We found limited evidence for 'eco-paralysis' (i.e. a passive state of pro-environmental behavioral stasis) at high levels of climate anxiety. Our results are consistent with the possibility that supporting adolescents' environmental efficacy will help climate-anxious adolescents engage in public sphere pro-environmental behavior.

Sluggish and Ion-Resilient Behavior of Interfacial Aqueous Layer on Single-Layer Graphene Oxide: Insights from In Situ Atomic Force Microscopy.

Understanding interfacial interactions of graphene oxide (GO) is important to evaluate its colloidal behavior and environmental fate. Single-layer GO is the fundamental unit of GO colloids, and its interfacial aqueous layers critically dictate these interfacial interactions. However, conventional techniques like X-ray diffraction are limited to multilayer systems and are inapplicable to single-layer GO. Therefore, our study employed atomic force microscopy to precisely observe the in situ dynamic behaviors of interfacial aqueous layers on single-layer GO. The interfacial aqueous layer height was detected at the subnanometer level. In real-time monitoring, the single-layer height increased from 1.17 to 1.70 nm within 3 h immersion. This sluggish process is different from the rapid equilibration of multilayer GO in previous studies, underscoring a gradual transition in hydration kinetics. Ion strength exhibited negligible influence on the single-layer height, suggesting a resilient response of the interfacial aqueous layer to ion-related perturbations due to intricate ion interactions and electrical double-layer compression. Humic acid led to a substantial increase in the interfacial aqueous layers, improving the colloidal stability of GO and augmenting its potential for migration. These findings hold considerable significance regarding the environmental behaviors of the GO interfacial aqueous layer in ion- and organic-rich water and soil.

Nanocolloids in the soil environment: Transformation, transport and ecological effects.

Nanocolloids (Ncs) are ubiquitous in natural systems and play a critical role in the biogeochemical cycling of trace metals and the mobility of organic pollutants. However, the environmental behavior and ecological effects of Ncs in the soil remain largely unknown. The accumulation of Ncs may have detrimental or beneficial effects on different compartments of the soil environment. This review discusses the major transformation processes (e.g., agglomeration/aggregation, absorption, deposition, dissolution, and redox reactions), transport, bioavailability of Ncs, and their roles in element cycles in soil systems. Notably, Ncs can act as effective carriers for other pollutants and contribute to environmental pollution by spreading pathogens, nutrients, heavy metals, and organic contaminants to adjacent water bodies or groundwater. Finally, the key knowledge gaps are highlighted to better predict their potential risks, and important new directions include exploring the geochemical process and mechanism of Ncs's formation; elucidating the transformation, transport, and ultimate fate of Ncs, and their long-term effect on contaminants, organisms, and elemental cycling; and identifying the impact on the growth and quality of important crops, evaluating its dominant effect on agro-ecosystems in the soil environment.

Environmental behavior and toxic effects of micro(nano)plastics and engineered nanoparticles on marine organisms under ocean acidification: A review.

Ocean acidification (OA) driven by human activities and climate change presents new challenges to marine ecosystems. At the same time, the risks posed by micro(nano)plastics (MNPs) and engineered nanoparticles (ENPs) to marine ecosystems are receiving increasing attention. Although previous studies have uncovered the environmental behavior and the toxic effects of MNPs and ENPs under OA, there is a lack of comprehensive literature reviews in this field. Therefore, this paper reviews how OA affects the environmental behavior of MNPs and ENPs, and summarizes the effects and the potential mechanisms of their co-exposure on marine organisms. The review indicates that OA changes the marine chemical environment, thereby altering the behavior of MNPs and ENPs. These changes affect their bioavailability and lead to co-exposure effects. This impacts marine organisms' energy metabolism, growth and development, antioxidant systems, reproduction and immunity. The potential mechanisms involved the regulation of signaling pathways, abnormalities in energy metabolism, energy allocation, oxidative stress, decreased enzyme activity, and disruptions in immune and reproductive functions. Finally, based on the limitations of existing research, actual environment and hot issues, we have outlined future research needs and identified key priorities and directions for further investigation. This review deepens our understanding of the potential effects of MNPs and ENPs on marine organisms under OA, while also aiming to promote further research and development in related fields.

3 Months without the car in Bielefeld, Germany- a mixed-method study exploring individual motivation to participate in a municipal intervention.

BACKGROUND: Climate change is a major public health issue worldwide. To achieve climate targets and reduce morbidity, a paradigm shift in individual behavior e.g., in mobility, is needed. Municipal interventions can motivate individuals to engage in climate-friendly behavior through different psychological mechanisms. In order for successful interventions, it is necessary to gain better insight from study participants and their reasons for participating in mobility projects (e.g., motivational aspects). MATERIALS AND METHODS: A mixed-methods design was used to evaluate reasons and characteristics of people for participating in an municipal mobility intervention. The quantitative sub-study assesses socioeconomic characteristics, environmental awareness and perceived stress. The qualitative sub-study explores motivation for participation and change, perspectives on car replacement and reasons for car use. RESULTS: Results show that participants (n = 42) are rather high educated and show medium environmental awareness. Participants of the qualitative study part (n = 15) were motiviated to reduce car use already before the intervention and used the intervention as starting point or trial phase. CONCLUSIONS: Urban intervention projects with fitted recruitment strategies and better insights from study participants with the aim to motivate individuals to engage in climate-friendly behavior can help to strengthen sustainability and public health.

Environmental assessment of phosphogypsum: A comprehensive geochemical modeling and leaching behavior study.

Understanding the variations in the geochemical composition of phosphogypsum (PG) destined for storage or valorization is crucial for assessing the safety and operational efficacy of waste management. The present study aimed to investigate the environmental behavior of PG using different leaching tests and to evaluate its geochemical behavior using geochemical modeling. Regarding the chemical characterization, the PG samples were predominantly composed of Ca (23.03-23.35 wt%), S (17.65-17.71 wt%), and Si (0.75-0.82 wt%). Mineralogically, the PG samples were primarily composed of gypsum (94.2-95.9 wt%) and quartz (1.67-1.76 wt%). Moreover, the automated mineralogy revealed the presence of apatite, fluorine and malladrite phases. The overall findings of the leaching tests showed that PG could be considered as non-hazardous material according to US Environmental Protection Agency limitations. However, a high leachability of elements at a L/S of 2 under acidic conditions ([Ca] = 166.52-199.87 mg/L, [S] = 207.9-233.59 mg/L, [F] = 248.62-286.65 mg/L) is observed. The weathering cell test revealed a considerable cumulative concentration over 90 days indicating potential adverse effects on the nearby environment (S: 8000 mg/kg, F: 3000 mg/kg, P: 700 mg/kg). Based on these results, it could be estimated that the surface storage of PG could have a serious impact on the environment. In this context, a simulation model was developed based on weathering cell results showed encouraging results for treating PG leachate using CaO before its disposal. Additionally, PHREEQC was used to analyze the speciation of major elements and calculate mineral phase saturation indices in PG leaching solutions. The findings revealed pH-dependent speciation for Ca, S, P, and F. The study identified gypsum, anhydrite, and bassanite as the key phases governing the dissolution of these elements.

Probing the CSR-pro-environmental behavior linkage: Insights into green reputation and chief sustainability officer influence.

This study aims to examine the impacts of internal and external corporate social responsibility (CSR) on managers' pro-environmental behaviors with the mediating role of green reputation and moderating of chief sustainability officer (CSO). We acquired information from 609 managers working in various Chinese manufacturing firms using a standardized survey tool. Structural equation modelling (SEM) was performed to analyze data. Our major findings are as follows. First, both internal and external CSR influence the pro-environmental behaviors of managers through the mediation role of corporate green reputation. Second, the CSO significantly moderates the relationship between CSR actions and corporate green reputation. Our study contributes to the body of current knowledge by giving empirical evidence for the theoretical framework linking CSR, reputation, and pro-environmental behavior. The findings from this study offer managerial insights for businesses that deliberately want to promote environmentally friendly activities.

Paths from simple game-targeted pro-environmental behaviors to more diverse pro-environmental behaviors: Empirical evidence from the Ant Forest app.

Game interventions have drawn much attention for their playful features and "painless" promotion of simple game-targeted pro-environmental behaviors (GPEBs), which could spill over to more "costly" prosocial behaviors for pro-environmental causes (PSBPs). The literature places much emphasis on game-targeted mechanisms (e.g., enjoyment and competition) to explain the impacts of game interventions, but pays little attention to non-game-targeted mechanisms to explore their spillover effect. Using online survey data from 1246 Chinese residents, this paper first compares players' and nonplayers' levels of engagement with GPEBs and with two common PSBPs, finding a positive spillover effect from game-targeted simple behaviors to more diverse PSBPs. Based upon goal theory, self-perception theory, and learning theory, the paper then examines the underlying mediating mechanisms of the positive relationship between GPEBs and PSBPs for subsamples of players and nonplayers respectively. The results demonstrate that individual awareness of problem and self-efficacy could be enhanced through engaging in simple GPEBs, which could spill over to more challenging and "costly" PSBPs, including charitable giving and volunteering for pro-environmental causes. The study provides important insights on helping to encourage specific types of more challenging PSBPs not directly targeted by the game.

Pro-environmental practice among young population: A scoping review.

INTRO: There is an inequality between pro-environmental knowledge acquisition and behavior. A change in behavior is required to solve both current and future environmental challenges since human behavior has an influence on pro-environmental practices. OBJECTIVE: Of the study was to carry out a critical analysis of current literature on Pro-environmental practices among the Young population. METHOD: The research question formulation on PICO served as the foundation for the search approach. Keywords were searched in different combinations from the popular databases SCOPUS, PubMed, Medline, Google Scholar, EMBASE, Google and Cochrane library Boolean operators (AND and OR) and keywords were employed in the search to avoid oversaturating the data. Fifteen full-text articles were selected for the study. RESULT: Review studies confirmed that youth engagement is highly valued, with evidence from increasing usage of information and communication technologies (education and environmental consciousness among young people. Analysis of pro-environmental practices and environmental behavior has to be given greater attention considering to the adverse impacts of the existing lifestyle on the environment. This made it possible to incorporate and simultaneously explore a variety of variables and effects on environmental practices, furthering the understanding of how these are interpreted. CONCLUSION: This study pointed up and made contributions to the expanding field of environmental practices barriers. The challenges found should be taken into account in its entirety and utilized to directly inform policies and procedures in order to promote adoption for practices reduction and remove the obstacles inhibiting change.

A Latest Review on Micro- and Nanoplastics in the Aquatic Environment: The Comparative Impact of Size on Environmental Behavior and Toxic Effect.

Micro and nanoplastics (MNPs) have attracted growing global research attention due to their distinct environmental impacts, addressing escalating concerns. The diverse materials, sizes, and shapes of MNPs result in a range of environmental impacts. Size, a crucial characteristic of MNPs, influences their environmental behavior, affecting processes like migration, sedimentation, aggregation, and adsorption. Moreover, size modulates the biodistribution and toxicity of MNPs in aquatic organisms. This review delves into the comprehensive impacts of plastic size, with a primary focus on environmental behavior and toxic effects. Ultimately, this review emphasizes the ecological implications of MNP size, laying a foundation for future research in this field.

Urban Microplastic Pollution Revealed by a Large-Scale Wetland Soil Survey.

Microplastics (MPs), as a new persistent pollutant, can be emitted and accumulated in urban environments, but there is no detailed information on the driving factors of MP pollution. In this study, through a large-scale wetland soil survey, the features of MPs were characterized in each urban area. The results showed an average abundance to be 379 n/kg in wetland soil. Polypropylene, fiber or fragment, and black color were common composition, shape, and color, respectively. The spatial distribution information showed that MP abundance was significantly relevant to the distance from the urban economic center. Furthermore, the correlation and regression analysis revealed that MP abundance was related to soil heavy metal and atmospheric particle (PM10 and PM2.5) concentrations (P < 0.05), while the promotion of socioeconomic activities (urbanization level, population density, etc.) may aggravate the pollution degree. Additionally, by using structural equation modeling, it was found that the urbanization level was the dominant factor driving the MP pollution degree, with a total effect coefficient of 0.49. Overall, this work provides multi-sided environmental information regarding MP pollution in urban ecosystems, which is significant for follow-up studies of MP pollution control and restoration.

Multi-process regulation of novel brominated flame retardants: Environmentally friendly substitute design, screening and environmental risk regulation.

Novel brominated flame retardants (NBFRs), one of the most widely used synthetic flame-retardant materials, have been considered as a new group of pollutants that potentially affect human health. To overcome the adverse effects of NBFRs, a systematic approach for molecular design, screening, and performance evaluation was developed to generate environmentally friendly NBFR derivatives with unaltered functionality. In the present study, the features of NBFRs (long-distance migration, biotoxicity, bioenrichment, and environmental persistence) were determined and characterized by the multifactor comprehensive characterization method with equal weight addition, and the similarity index analysis (CoMSIA) model was constructed. Based on the three-dimensional equipotential diagram of the target molecule 2-ethylhexyl tetrabromobenzoic acid (TBB), 23 TBB derivatives were designed. Of these, 22 derivatives with decreased environmental impact and unaltered functional properties (i.e., flame retardancy and stability) were selected using 3D-QSAR models and density functional theory methods. The health risks of these derivatives to humans were assessed by toxicokinetic analysis; the results narrowed down the number of candidates to three (Derivative-7, Derivative-10, and Derivative-15). The environmental impact of these candidates was further evaluated and regulated in the real-world environment by using molecular dynamics simulation assisted by the Taguchi experimental design method. The relationship between the binding effects and the nonbonding interaction resultant force (TBB derivatives-receptor proteins) was also studied, and it was found that the larger the modulus of the binding force, the stronger the binding ability of the two. This finding indicated that the environmental impact of the designed NBFR derivatives was decreased. The present study aimed to provide a new idea and method for designing NBFR substitutes and to provide theoretical support for restraining the potential environmental risks of NBFRs.

Pro-environmental food practices in EU countries strongly suggest mutually reinforcing improvements in gender equality and environmental sustainability.

This paper seeks to understand how pro-environmental food practices among women and men in the EU can be supported by considering the interlinkages between gender equality and environmental sustainability. A special aspect is that the role of gender equality is interpreted in terms of Schwartz's theory on national cultural values, which relates gender equality to cultures that emphasize intellectual autonomy and egalitarianism. The paper investigated how pro-environmental food practices (including meat reduction) among women and men correlated with their countries' national income level and its level of gender equality. It was a multilevel analysis of survey data from 27 countries (Eurobarometer 95.1, Spring 2021). Considering that studies about gender equality and the environment often find problematically high correlations between gender equality and national income, this study focused on political gender equality (i.e. women's representation in parliament), which had desirable characteristics. National income and political gender equality had complementary impacts on the adoption of pro-environmental food practices (including meat reduction). Men reported more target practices when living in richer countries; the same applied even more strongly to women when living in richer and more politically gender-balanced countries. It was concluded that women may have developed more autonomy by, inter alia, adopting pro-environmental food practices. At the level of individual behavior, this illustrates "mutually reinforcing dynamics" in the pursuit of gender equality and environmental sustainability goals.

Organized activities in adolescence and pro-environmental behaviors in adulthood: The mediating role of pro-environmental attitudes.

INTRODUCTION: Organized activities practiced in adolescence are known to foster positive development, including active citizenship. Active citizenship encompasses a wide range of behaviors, one of them being pro-environmental behaviors. Few studies focused on the developmental factors that may predict these behaviors in adults, despite their crucial role in counteracting the current climate crisis. However, prior research showed that attitudes were typically major predictors of behaviors. This study thus tested a model that posited participation in organized activities in adolescence as a predictor of pro-environmental attitudes in emerging adulthood and these attitudes as a predictor of pro-environmental behaviors in adulthood. METHODS: Three hundred twenty-one participants (61% girls) from Quebec (Canada) completed all time points across a 17-year period. Participants self-reported their participation in organized activities (sports, cultural, prosocial) from ages 14 to 17, pro-environmental attitudes, from ages 18 to 22, and pro-environmental behaviors, at age 30. RESULTS: Results revealed that pro-environmental attitudes mediate the relationship between adolescent participation in cultural activities and pro-environmental behaviors in adulthood. Practicing sporting or prosocial activities in adolescence did not predict stronger pro-environmental attitudes or behaviors. Interestingly, pro-environmental attitudes consistently predicted pro-environmental behaviors later in life. CONCLUSIONS: These findings and prior research suggest that participation in cultural activities may provide a space to discuss, imagine change, and cultivate sensitivity towards nature. This may contribute to the development of pro-environmental attitudes and behaviors later in life.

Degradation of a New Herbicide Florpyrauxifen-Benzyl in Water: Kinetics, Various Influencing Factors and Its Reaction Mechanisms.

Florpyrauxifen-benzyl is a novel herbicide used to control weeds in paddy fields. To clarify and evaluate its hydrolytic behavior and safety in water environments, its hydrolytic characteristics were investigated under varying temperatures, pH values, initial mass concentrations and water types, as well as the effects of 40 environmental factors such as microplastics (MPs) and disposable face masks (DFMs). Meanwhile, hydrolytic products were identified by UPLC-QTOF-MS/MS, and its hydrolytic pathways were proposed. The effects of MPs and DFMs on hydrolytic products and pathways were also investigated. The results showed that hydrolysis of florpyrauxifen-benzyl was a spontaneous process driven by endothermic, base catalysis and activation entropy increase and conformed to the first-order kinetics. The temperature had an obvious effect on hydrolysis rate under alkaline condition, the hydrolysis reaction conformed to Arrhenius formula, and activation enthalpy, activation entropy, and Gibbs free energy were negatively correlated with temperature. Most of environmental factors promoted hydrolysis of florpyrauxifen-benzyl, especially the cetyltrimethyl ammonium bromide (CTAB). The hydrolysis mechanism was ester hydrolysis reaction with a main product of florpyrauxifen. The MPs and DFMs did not affect the hydrolytic mechanisms but the hydrolysis rate. The results are crucial for illustrating and assessing the environmental fate and risks of florpyrauxifen-benzyl.

Will attitudes corrected by social norms have a more powerful impact on pro-environmental behavior? Evidence from a process model moderated by self-construal.

Residents' pro-environmental behaviors are considered important for reducing carbon emissions and achieving carbon neutrality. However, optimizing the implementation of pro-environmental behavior need to be further studied. To this end, we placed residents' recycling behavior within a socialized situation. Explored the "Attitude-Behavior intention-Behavior" intermediary path regulated by self-construal, whether and how it can more effectively promote residents to transfer recycling behavior intention as recycling behavior after joining the influence of social norms. The results showed that after considering the influence of social norms, the transformation of residents' Habit adjustment recycling behavior (HAB) was significantly improved. Further, the masking effect of "Behavioral intention-Interpersonal facilitation recycling behavior (IFB)" in the mediation model was effectively reduced. HAB and IFB had stronger dependence on independent self-construal (IDSC) and interdependent self-construal (ITSC), respectively. In addition, when the self-construal level was low, the overall effect of the chain mediation model was stronger, highlighting the advantage of the role played by social norms.

Measuring environmental awareness: An analysis using google search data.

Environmental awareness is usually measured using surveys. This paper aims to offer an alternative measure: an Environmental Awareness Index (EAI) constructed using Google search data provided by Google Trends. The benefits of using Google search data over surveys are that (i) they are less costly to obtain, (ii) they are available at high frequency, and (iii) they cover countries where no surveys are available. To test the validity of the proposed EAI, this study empirically assesses the impact of the computed index on individuals' pro-environmental behaviors using the Special Eurobarometer: Attitudes of European citizens towards the Environment data. Results show that the EAI is positively related to pro-environmental behaviors with a statistical significance at the one percent level. This finding stays robust in pooled OLS as well as in panel regression analysis when GDP, mean years of schooling, and population are included as control variables and when time-fixed effects are introduced. Further, the results confirm that environmental awareness is not stable over time and underline the importance of having a timely measure of environmental awareness at hand. Finally, the findings offer several practical implications for managers and policymakers, who will be able to use a timely measure of environmental awareness, assess and measure the impact of their policies aiming to raise environmental awareness as well as depict the type of behavior influenced by their policies.

Investigating the Role of Goals and Motivation on Waste Separation Behavior Through the Lens of the Theory of Reasoned Goal Pursuit.

Nowadays the prediction and change of waste-related behaviors represent a key topic for scholars and policy makers. The theoretical mainstays applied to waste separation behavior, such as the Theory of Planned Behavior (TPB), the Norm Activation Model and the Value Belief Norm, do not include the construct of goal in their formulation. Other goal-focused theories, such as the Goal Systems Theory (GST), lack applications on separation behavior. Recently, Ajzen and Kruglanski (2019) have proposed the Theory of Reasoned Goal Pursuit (TRGP) which combines TPB and GST. Considering TRGP has the potential to offer further insights on human behavior and, to our knowledge, there is no application of TRGP to recycling behavior yet, this paper analyses waste separation behavior of households in Maastricht and Zwolle (The Netherlands) under the lens of TRGP. Although waste separation behavior represents a kind of habitual behavior, this paper highlights the influence of goals and motivation on intention to separate waste. Furthermore, it offers some indications to promote behavior change and some suggestions for future research directions.

The concern about main crises such as the Covid-19 pandemic, the war in Ukraine, and climate change's impact on energy-saving behavior.

The number of crises experienced around the world forces people to reconsider and reassess various aspects of their lives. The energy crisis caused by the war in Ukraine and uncontrolled climate change revealed the importance of energy-saving behavior. Thus, the aim of this paper is to analyze the concerns about current crises such as the Covid-19 pandemic, the war in Ukraine, and climate change's impact on energy-saving behavior and changes in environmental concern. Referring to the survey conducted in Lithuania in 2022, where 1000 respondents participated, the results revealed that the war in Ukraine was the most concerning problem. The level of climate change concern was slightly lower. Meanwhile, the Covid-19 pandemic was the least important problem in Lithuania in 2022. Furthermore, respondents stated that the Covid-19 pandemic contributed to the changes in environmental concern and energy-saving actions more than the war in Ukraine did. Meanwhile, the Generalized Linear Model results revealed that only the war in Ukraine positively and significantly influenced energy-saving behavior. The Covid-19 pandemic concern negatively affected energy-saving behavior, while the climate change concern factor affected it indirectly, as the interaction of attitudes toward energy consumption. Thus, this study revealed the main aspect of and how to encourage energy-saving behavior in the context of the main current crises.
