Towards a plastic-less planet. Gender and individual responsibility predict the effect of imagery nudges about marine (micro)plastic pollution on R-behavior intentions
Summary
Researchers tested the effectiveness of online nudges (images and short messages) in promoting microplastic-conscious consumer behaviors in Spain (n=671), finding that gender and individual responsibility mindset predicted how strongly nudges influenced intentions to reduce, replace, and recycle plastic.
Emerging microplastics (MP) pollution is one of the biggest threats for the oceans today. Consumers could reduce MP pollution adopting R-behaviors such as reducing consumption of plastic, refusing products with MP, replacing them for green products, and recycling. Here we tested the efficiency of online nudges (images and short messages) for promoting MP-conscious behavior in Spain (n = 671). The perceived level of environmental responsibility and the willingness to adopt R-behaviors were measured. Messages about seafood with MP and plastic-polluted marine environment were more efficient than images of animals killed by plastics. Feeling responsible for MP pollution predicted R-behavior intention. Women would adopt more R-behaviors than men, while men were more sensitive than females to the proposed nudges. Raising the sense of environmental responsibility would be priority in education campaigns. For different cultural sensitivities to animal suffering, evoking environmental health instead of threats to wildlife would be generally recommended.

Extending the theory of planned behaviour to investigate the issue of microplastics in the marine environment
Researchers extended the theory of planned behaviour to investigate public attitudes toward marine microplastic pollution, finding that environmental awareness and perceived behavioral control significantly predicted consumers' intentions to reduce microplastic-generating product use.
Do Social Media Posts Influence Consumption Behavior towards Plastic Pollution?
Researchers surveyed 213 individuals to assess how social media posts influence consumer behavior toward plastic pollution, finding that information campaigns on social media can shift attitudes and reduce plastic consumption intentions.
Who worries about microplastics? The relative importance of personal values and individual risk judgements / ¿A quién le preocupan los microplásticos? La importancia relativa de los valores personales y los juicios individuales de riesgo
Researchers surveyed nearly 700 people in Norway to understand what drives public worry about microplastic pollution. They found that personal values and individual risk perceptions were the strongest predictors of concern, more so than demographic factors or general environmental attitudes. The study suggests that communication strategies about microplastic risks should account for how people personally evaluate threats rather than relying solely on scientific information.
On the way to reduce marine microplastics pollution. Research landscape of psychosocial drivers
A review of psychosocial drivers of marine plastic pollution found that factors including consumer convenience preferences, low perceived personal responsibility, and weak norm activation explain why behavioral change around plastic use is slow, and that interventions combining social norms messaging with structural changes show the most promise.
Enhancing marine citizenship as a strategy to promote the reduction of single-use plastics consumption in different cultures
Researchers studied single-use plastic (SUP) consumption behaviors and the concept of 'marine citizenship' — personal responsibility for ocean health — across different national cultures to evaluate whether promoting marine citizenship can reduce SUP use and drive adoption of sustainable alternatives. The study examined how cultural context shapes the effectiveness of marine citizenship-based intervention strategies for reducing plastic pollution at the consumer level.
