People can be motivated to engage in collective action for climate protection because they are angry about an injustice or because they are emotionally moved by the idea that they can achieve something together. However, previous research on emotions and collective action has not distinguished between being positively and being negatively moved and between normative and non-normative collective action. To address this gap, we conducted a field study in Germany with activists and non-activists of Fridays for Future (N = 223). Participants reported their appraisals, feelings and intentions related to the climate crisis and the Fridays for Future protests. Being positively moved predicted intentions to engage in normative collective action (signing petitions, participating in demonstrations) but not intentions to participate in non-normative collective action (involving damage to property or risk of personal injury). Being negatively moved did not significantly predict either of these collective action intentions. This suggests that the motivational effect of being moved on collective action is specific to being positively moved and to normative collective action. Acceptance of non-normative collective action was predicted by perceptions of injustice and low collective efficacy beliefs. Thus, non-normative collective action for climate protection seems to be considered when peaceful protest is perceived as ineffective.
