Non-technical summary. This study addresses the challenge of climate change by exploring how psychological qualities and meditation practices may influence pro-environmental behavior among decision-makers, by surveying 185 participants. The research found that meditation practices and compassion toward others are linked to more pro-environmental actions. Nature connectedness emerged as a key factor related to enhanced mindfulness, compassion toward others and self, and environmental efforts. Additionally, pro-environmental efforts at work were related to more engagement across the organization, including management. These findings highlight the potential of integrating personal growth practices into sustainability promoting strategies, suggesting that fostering compassion and mindfulness may support pro-environmental action. Technical summary. Current policy approaches addressing climate change have been insufficient. Integrative approaches linking inner and outer factors of behavior change, both at the private and organizational level, have been called for. The aim of the present study was thus to conceptualize and test a model of interlinkages between trainable transformative psychological qualities, meditation practice, wellbeing, stress, and pro-environmental behaviors in the private and organizational context, among decision-makers (N = 185) who responded to a survey of self-completion measures covering the topics above. Results show that meditation practices and longer practice duration were associated with more pro-environmental behavior, mindfulness facets, and wellbeing. Mindfulness facets and self-compassion were associated with higher wellbeing and lower stress, but not pro-environmental behavior. Importantly, higher compassion toward others was associated with more pro-environmental behavior but was not associated with own wellbeing and stress. Greater nature connectedness was associated with more proenvironmental behavior in private- and work life, mindfulness facets, compassion toward others, self-compassion, and longer meditation duration. Furthermore, at work, personal pro-environmental efforts were associated with such efforts by others in the organization, including management, and such efforts were also associated with overall integration of sustainability work in the organization. The results can help guide future interventions. Social media summary. Nature connectedness, compassion toward others, and meditation related to private and work life pro-environmental behaviors.
