RT Journal Article T1 Not all green behaviors are equal: Efficiency practices reduce moral licensing while curtailment practices increase it A1 Pasca García, Laura A1 Moreno Gata, Sofía AB Not all pro-environmental behaviors are equally effective in fostering sustainable habits. Psychological mechanisms, such as moral licensing, can paradoxically reduce the positive impact of well-intentioned actions. In this pre-registered quasi-experimental study (N = 514), we examined how curtailment behaviors (e.g., recycling) and efficiency behaviors (e.g., adopting a vegan/vegetarian diet) differently influence moral credentials and subsequent pro-environmental actions. Results showed that salient curtailment behaviors lowered guilt and perceived environmental impact after unsustainable actions, creating a potential licensing effect, whereas efficiency behaviors mitigated this effect and promoted further sustainable behavior. Crucially, feelings of guilt and perceived environmental impact predicted later pro-environmental engagement. These findings highlight that encouraging high-impact efficiency behaviors may prevent moral licensing and support more consistent sustainable choices, offering actionable insights for interventions aimed at fostering lasting environmental behavior change.
