AbstractCompany activities are important contributors to climate change. Consumers take companies' actions toward environment into account when they decide to engage with these companies. We study under which conditions corporate misconduct with respect to climate change outrages consumers, eliciting negative moral emotions. Moreover, we explore the capacity of these negative moral emotions to energize consumer decisions and action tendencies to retaliate against “offending” companies. Testing two moderated mediation models on random samples of 152 adult citizens of the United States and 159 adult citizens of France, we show that negative moral emotions experienced by consumers that witness corporate malfeasance toward the climate determine negative attitudes toward the company and intentions to penalize it. Moreover, for both samples, empathy, collective self, and moral identity moderate the relationship between the perception of corporate irresponsibility and moral emotions, while the effect of political orientation is culturally specific. These findings help to uncover under which conditions consumer hostile responses toward corporate misconduct takes place.
