This paper investigates how promotions of knowledge and social embeddness shape consumers’ participation in sustainable consumption. An extended model of goal-directed behaviour is tested under airline consumers who have participated in voluntary carbon offset (VCO) program. Results show consumer’s knowledge positively influences their subjective norm but not their attitude towards participation of VCO. Increasing consumers’ sense of social embeddedness is also found to be crucial in forming subjective norm and their attitude. Finally, positive anticipated emotion influences consumers’ desire to participate in VCO, while negative anticipated emotion did not. The findings of this research reveal how interactive promotions influence individual’s internal processes for sustainable consumption, as well as highlight the need for different emotional elicitation strategies for different sustainability programs.
