Abstract

Consumer behavior plays a crucial role in the transition toward sustainability, yet traditional policy approaches often rely on financial incentives, which may not be the most cost-effective or scalable solution. This study examines the impact of behavioral economic interventions—specifically default options, social norms, and framing effects—on sustainable purchasing decisions. A randomized controlled experimental design was employed, assigning 500 participants to four groups, including a control group. In parallel, survey data from 1,000 consumers were analyzed to assess broader attitudes toward sustainable consumption. The experimental phase was conducted online between January–March 2024, ensuring methodological clarity regarding data collection procedures. In parallel, survey data from 1,000 consumers were analyzed to assess broader attitudes toward sustainable consumption. Results indicate that default options significantly increased sustainable purchases (78%), nearly matching the effectiveness of financial incentives (80%), without requiring direct subsidies. Social norms messaging also proved effective (74% adoption rate), reinforcing the influence of peer behavior. Framing interventions produced a moderate increase (70%), suggesting that message presentation shapes consumer decision-making. Generational patterns were also observed, with younger consumers responding more strongly to informational and norm-based cues, consistent with recent evidence on demographic variability in sustainable consumption. These results align with emerging research showing that perceived value, social identity, and anticipated emotions significantly shape sustainable purchasing decisions. However, perceived barriers such as cost concerns (65%), inconvenience (62%), and lack of information (58%) remain significant obstacles to adoption. These findings underscore the potential for non-monetary behavioral interventions to complement or replace traditional financial incentives in sustainability policy. Furthermore, the effectiveness of these interventions corresponds with recent systematic evaluations emphasizing the need for multi-component, evidence-based sustainability strategies. Future research should explore long-term habit formation and cross-cultural variations to refine behavioral strategies for maximum impact. By integrating insights from behavioral economics, policymakers and businesses can develop cost-effective, scalable interventions to promote sustainable consumer behavior.
