This study investigates the relationship between nature connectedness, mindful consumption, and pro-environmental behaviors, with an emphasis on the role of policy interventions in fostering sustainable actions. In this context, the research uses a mixed-methods design including surveys and interviews to explore how individuals’ emotional and cognitive connectedness to nature impacts their environmental practices and why mindfulness is a key component of responsible consumption. As such, with respect to the research objectives, the study reveals that higher levels of nature connectedness are positively related to a greater extent of pro-environmental behavior. In addition, mindful consumption is an important factor in explaining responsible environmental practices. At the same time, a number of psychological and socio-economic obstacles, as well as a lack of knowledge, present barriers to universal adoption of the target behaviors. Simultaneously, the target behaviors can be cultivated through policy interventions as well as natural and forced experiments, such as a plastic bag ban or waste reduction program, and the target behaviors can be effectively cultivated through these interventions, which is associated with policy implications. In conclusion, it is necessary to integrate nature connectedness considerations into environmental strategies at the national and global level.
