<p>Consumers play a central role in transitioning to a circular economy, yet research often treats pro-circular behaviors in a generalized manner, overlooking sectoral dynamics. This study presents a systematic literature review and bibliometric analysis of 383 peer-reviewed articles, advancing an explicit sectoral framework to examine how pro-circular consumer behaviors are studied and what drives their adoption across primary, secondary, and tertiary sectors. By using bibliometric analysis to map trends and thematic clusters, and then manually doing content analysis to categorize behaviors and drivers, the review traces the evolution of the field, identifies behavioral patterns, and enables a systematic, sector-specific synthesis of existing evidence. A key contribution of this research is its sector-based framework, which reveals differentiated research patterns and gaps, including a strong concentration of studies in the secondary sector (especially electronics and fashion), while the primary and tertiary sectors remain underrepresented. Four major consumer behaviors emerge academic literature: reduce consumption and waste, green acquisition, product lifetime extension, and end-of-life management. These are influenced by five categories of factors, established from literature: consumer characteristics, circular knowledge, attitudes &amp; perceptions, consumer-product attachment, product and brand characteristics, and contextual factors. By synthesizing and quantifying the diverse behaviors and factors across sectors, this study highlights the need for sectoral and behaviorally tailored strategies to promote circularity, particularly in service-based contexts. By clarifying how pro-circular behaviors and drivers differ by sector, this review provides a structured foundation for future research, theory development, and policy-making aimed at strengthening consumer participation in circular systems.</p>
