A visual scoping review of plastic consumption in everyday life

Abstract

This scoping literature review aimed to understand state-of-the-art knowledge about plastic consumption in the context of daily life by identifying controversies and interventions addressed in the reviewed articles. First, we reviewed articles based on theoretical approaches, methodologies, and country contexts. Second, using a concept map, we analyzed key concepts and dilemmas inherent in plastic consumption, highlighting its complexity. Third, we identified various approaches to interventions for reducing plastic consumption, along with stakeholders' perceived responsibilities to initiate and implement these changes. We found that in the existing research, behavioral studies are central to the investigations of plastic consumption and primarily focus on single-use plastic products (SUPs), yet within a very narrow scope of product variation. Hence, much of the existing research concentrates on a narrow subset of SUP items, while other significant SUPs and consumer products remain underexplored. We argue that the challenges associated with plastics extend far beyond individual behaviors related to specific products and materials. Finally, we identified research gaps and proposed future studies to expand the scope of plastic products covered, adopt systemic approaches to plastic consumption dilemmas, and explore relational and holistic perspectives beyond disciplinary norms. Drawing on the research-policy nexus on plastic consumption, we emphasize the importance of critically reflecting on how knowledge is produced and applied in policymaking. To achieve just and sustainable transitions, policymakers should prioritize equitable solutions that do not disproportionately burden specific stakeholders, such as consumers, while holding all relevant parties accountable.
