Although there has been a steady increase in the number of studies on consumer behaviour in relation to sustainable development, there is limited focus on the product disposal phase. This systematic literature review intends to: (1) clarify how concepts related to pro-environmental consumer behaviour are understood and analysed in the academic literature on waste management; (2) discover any interplay between pro-environmental consumer behaviour and generic consumer behaviour, and the conditions and factors that favour it. A typical systematic literature review methodology was applied to the papers available on Web of Science, Science Direct and EBSCO (Elton Bryson Stephens Company) host between 1975 and 2019, leading to the selection of 699 final papers. The findings reveal that: (1) Although scholars tend to create a variety of pro-environmental consumer behaviour models depending on their specific field of inquiry, all approaches can be traced back to a limited number of reference theories; (2) The overall level of interplay between pro-environmental consumer behaviour and generic consumer behaviour is limited, nevertheless a favourable context or a supportive institutional-legal framework can significantly influence it; (3) A plethora of conditions and factors favour this type of interplay, involving social psychology, laws, economics, institutions and more; (4) Several critical issues appear in the analysed papers, especially some scholars’ assumptions to be able to identify all key factors. It follows the need for a more interdisciplinary approach, a deeper analysis of the effectiveness of the intervention measures at the governmental and institutional level, and a clear classification of factors and conditions (as proposed by this review).
