**Abstract** Despite existing links between personality and environmental attitudes, behavioral change interventions promoting plant-based eating in order to help climate change mitigation, have yet to consider the role of those individual differences. Recent evidence suggests an improved efficacy of such interventions targeted at barriers (e.g., food neophobia) of three different types of meat consumers over non-targeted interventions (e.g., completion of unrelated surveys). Based on those findings, we want to expand segmentation research of dietary choices by the consideration of personality as a barrier and benefit of reducing animal product consumption. Segmentation analysis will be performed in order to investigate whether personality factors into the proposed types of meat-eaters. For this purpose, the Big Five and Dark Triad will enter both latent profile analysis and cluster analysis in an online sample of N_min=1000 participants, alongside previously identified constructs (e.g., environmentalism, food-neophobia, meat attachment).
