Sustainable consumption is hampered by a discrepancy between consumers’ attitudes and their actual behaviour in the market place. Psychological construal level theory provides an explanation for the attitude to behaviour gap as a motivational conflict between high and low level of mental construal. Based on self-determination theory it is argued that this motivational conflict presupposes extrinsic motivation for sustainable behaviour. Based on self-regulatory styles, the present paper identifies and illustrates four types of intervention strategies that can cater for extrinsic motivation for sustainable development among light users. The underlying mechanisms of these interventions suggest that the transition from external to internal regulation is catalysed by social feedback.
