Climate change mitigation requires changes in greenhouse gas emitting behaviours. This dissertation aims to provide insights into the influences of behaviour change for two high-impact pro-environmental behaviours: climate policy support and consumption of animal products. It does so by using quasi- and randomized experiments and by monitoring changes in behaviour over time. Study 1 examined changes in climate policy support and climate change risk perception over the course of a naturally occurring event: seasonal forest fires. It employed growth curve modeling techniques in a structural equation modeling framework to analyze longitudinal relations between these two constructs over time, and to examine growth in climate change risk perception while controlling for the effect of exposure to forest fires and other extreme weather. Indirect exposure to forest fires (e.g., media) had a modest effect on climate change risk perception. Climate change risk perception for individuals with above-mean perceptions of scientific agreement tended to increase faster than for those with below-mean perceptions. Individuals whose climate change risk perception grew at a faster-than-average rate tended to also grow at a faster-than-average rate for climate policy support. Study 2 provided insight into the psychological influences on consumption of animal products and on willingness to reduce. Following a comprehensive literature review, known influences were examined using Latent Profile Analysis to identify groups of individuals with similar perceptions of facilitators of meat consumption and obstacles to reducing it. Three groups were identified: strong-hindrance meat eaters, moderate-hindrance meat eaters, and reducers. Validation variables confirmed the practicality of the three profiles: groups differed in their current consumption of animal products and in their willingness to reduce. Using these findings, three group-matched interventions were designed in Study 3. Intervention design was informed by four behaviour-change frameworks. Participants were randomly assigned to one of four conditions: control condition, implementation-intention condition, information-and-healthy-recipe condition, and information-and-substitution condition. Then, they completed up to 28 days of food diaries. Multilevel model analyses were employed to examine changes in the consumption of animal products over time. Participants reduced their consumption by 20 grams of CO2 per day on average. Individuals that were randomly assigned to an intervention condition that matched their meat-eater profile reduced their consumption of animal products by 40 grams CO2 per day on average. Taken together, these studies highlight the importance of considering individual differences (i.e., tailoring) when designing pro-environmental behaviour interventions. / Graduate

Whilst several studies acknowledge the role of gender norms and structures in environmental research, little attention is paid to the explicit influence of men and masculinities in pro-environmental behavior. Additionally, research concerning this man-environment nexus is almost nonexistent in the context of the Global South. This thesis aims to address this research gap by analyzing the influence of hegemonic masculinity norms on the attitudes of male university students in Rabat, Morocco to engage in pro-environmental behavior. The research is conducted by qualitative semi-structured focus group interviews with 15 male university students in Rabat during May and June 2023, with a theoretical framework drawing upon Martin Hultman and Paul M. Pulé’s theoretical efforts of Ecological Masculinities. The findings suggest that the contextual hegemonic masculinity norms socialize the respondents into internalizing a myopic approach to engaging in pro-environmental behavior; materializing into either anti-environmental attitudes or, more prominently, techno-scientific solutionist attitudes. Relatedly, the respondents dismiss engaging in the individual pro-environmental behaviors considered feminine in order to avoid judgements, social exclusion and demasculinization. The thesis concludes by delineating the importance of including men and multiple masculinities in environmental research, especially as men can be considered the gatekeepers to transformative climate change adaptation and mitigation.

Energy consumption is one of the major contributors to greenhouse gas emissions and to climate change. Renewable energy sources are one way of mitigating the problem, but behavioral change and reductions in consumption are also required. In addition, little is known about how energy conservation behaviors are driven or hindered at workplaces, but it has been found in previous research that employee engagement is an important factor. Therefore, this study takes a mixed method approach utilizing the framework of Community-Based Social Marketing at a pharmaceutical manufacturing site in Sweden to investigate drivers and barriers to energy conservation, designing an intervention aiming at increasing employee engagement as well as changing behaviors, and evaluating the study using interviews, surveys and real time measurements. The findings of this study suggest that several factors act as barriers and drivers to energy conservation behaviors at work, e.g., interest, organizational culture, work processes and commitment from the company and management. The designed intervention, an inclusionary trans- disciplinary workshop, seems to have increased engagement and has preliminarily influenced pro-environmental behavior changes, as well as mitigated some barriers and strengthened some drivers.

Abstract  Background: Growing global concerns about sustainability highlight the importance of environmental sustainability, particularly environmentally conscious behaviors. There has been a growing focus on pro-environmental behavior (PEB) as a way for individuals to minimize their environmental impact. Global environmental challenges underscore the pressing need for proactive environmental action, particularly the growing emphasis on the importance of motivating individuals' daily actions and choices, as they directly contribute to environmental conservation and pro-environmental behavior. In the context of Sweden, the country is widely recognized for its commitment to environmental sustainability. Moreover, considering the increasing number of international university students in Sweden, it contributes to the academic environment and allows for the exploration of environmental behaviors within a diverse population. Given this, understanding, and promoting pro-environmental behaviors among this demographic in Sweden is essential, and it also helps contribute to the societal commitment to environmental conservation.  Purpose: This thesis aims to investigate the determinants that influence pro-environmental behavior among international university students in Sweden, employing social cognitive theory and the reciprocal determinism model. Focusing on personal (internal) factors like environmental knowledge and attitudes as well as environmental (external) factors like subjective norms and place attachment, this thesis also explored the interaction between pro-environmental behavior and its associated factors. By understanding these factors’ roles, this thesis aims to contribute to the development of effective strategies for promoting pro-environmental behavior among this population. Method: This thesis adopts a quantitative approach to examine the interplay of variables via an online survey. Data were collected from 203 individuals in Sweden, focusing on investigating the relationships between different factors and pro-environmental behavior based on eight formulated hypotheses. Respondents were selected using judgmental sampling, and data analysis was conducted using techniques such as Pearson’s correlation and multiple regression analysis in SPSS.  Conclusion: The results of this thesis reveal a significant association between different factors and pro-environmental behavior among international university students in Sweden. Specifically, environmental attitude and place attachment were found to positively influence pro-environmental behavior. Moreover, subjective norms were shown to have a positive impact on both environmental knowledge and attitude. However, neither the relationship between place attachment and environmental knowledge nor the relationship between environmental knowledge and subjective norms had any significant impact on pro-environmental behavior.

Most efforts to categorize pro-environmental behaviors (PEBs) have focused on researchers’ – rather than laypeople’s – perceptions of PEBs. Drawing on the psychometric paradigm used to categorize environmental risks, we aimed to identify the PEB attributes salient to laypeople and, from that, determine the underlying dimensions of PEB. In Study 1, participants (n = 157) evaluated 30 PEBs through open-ended questions. The results revealed 21 attributes that laypeople commonly associate with PEBs. In Study 2, 250 MTurk participants rated 74 PEBs on the 21 attributes. An exploratory factor analysis revealed four factors underlying PEB: Factor 1 (Financial and Behavioral Cost), Factor 2 (External Pressures), Factor 3 (Environmental Impact and Savings) and Factor 4 (Health and Safety Impacts). PEBs were characterized along each dimension and along multiple dimensions using biplots. Additionally, the four factors strongly predicted behavior intention. The results have implications for interventions to increase PEBs in the general public.

In today’s society, environmental concern might be at a historical peak. 2778 companies in 60 countries have now acquired the Benefit-Corporation (B-Corp) Certification in attempts to demonstrate their environmental responsibility. The aim of the present study was to investigate the effects of implementing the B-Corp Certification in a USA automotive dealership on employee pro-environmental behavior and life satisfaction, with consideration of the moderating role of commitment to the B-Corp Certification. A within-group quasi-experimental design was used to investigate the effects of the certification over a 5-month period through self-reported measures. Thirty-three employees participated in this study. One-way repeated-measures ANOVA was conducted to measure differences in employee pro-environmental behavior before and after the implementation of the B-Corp Certification. Through bivariate correlations the relationship between employee pro-environmental behavior and life satisfaction was analyzed. Partial correlation was used to test the moderating role of commitment in determining the strength of the implementation on employee pro-environmental behavior. There was no difference between pre- and post-measurements of employee pro-environmental behavior. Commitment to the B-Corp Certification did not moderate the effectiveness of the implementation of the B-Corp Certification on employee pro-environmental behavior. Additionally, no relationship was found between pro-environmental behavior and life satisfaction. Finally, results are discussed within the context of industrial- and organizational(IO) psychology, as are the implications for future research and interventions aimed at increasingemployee pro-environmental behaviors.
