The present consumption has far exceeded the earth’s capacity and it is being said that we are moving further and faster away from sustainability agenda. Extant literature suggests, embracing sustainable consumption (consuming products and services with minimal negative impact on the environment, and positive impact on societal wellbeing) could be the surest way to mitigate this detrimental effects. Increasingly studies propose adopting psychological approaches in boosting sustainable consumption behaviors but only a handful of them have investigated the association between facets of mindfulness and sustainable consumption behaviour. Based on extant literatures, the present study aims at conceptualizing and empirically investigate the relationship between mindfulness and sustainable consumption behaviour and shed light on how dispositional envy and pro-social behaviour mediates this relationship, especially in young Indian millennials.
