Increasing and promoting recycling is crucial to achieving sustainable consumption. However, this is a complex task that involves the interplay of beliefs, knowledge and situational factors in ways not yet understood. This study examines a spill-over model in which perceived consumer effectiveness influences the adoption of an easy task (carrying reusable shopping bags) and that, in turn, influences recycling. Using data from a national survey with a representative sample of 1286 respondents in Colombia, we test a hypothesized path using a mediation model. Our results suggest that the relationship between perceived consumer effectiveness and recycling is mediated by the use of reusable shopping bags. Thus, once the adoption of simple pro-environmental behavior is triggered by pro-environmental beliefs, spillover effects may ensue to favor the adoption of recycling behavior. This suggests that individuals may adopt pro-environmental behavior in stages or levels. Therefore, focusing on behaviors that require less effort (e.g., reducing/reusing) could be a starting point when it comes to encouraging the adoption of other behaviors that demand a greater level of effort such as recycling. This study suggests that attitudinal variables can be the starting point of spill-over effects.

The concept of sustainable consumption has been described in the literature from different perspectives, but few have focused on defining the consumer perspective and strategies to appropriate this knowledge and behaviors in the classroom, which becomes a major challenge in times of Covid 19 and confinement. This article proposes an approach to the concept by university students from the implementation of a pedagogical strategy, which involved the implementation of a virtual learning community and the evaluation of the understanding of this concept through the use of mind maps (pre and post). Through the mind maps, data were collected to evaluate the understanding of the concept, the analysis of semantic richness and systemic complexity. The results show the associations established by the students, proposing a categorization system arising from the data and the previous literature review. The study concludes that the students broadened their vision of sustainable consumption in terms of the actors involved, consumption decisions and the social and environmental dimensions of sustainability.

Circular economies have focused on managing organizations and changes in production and consumption models that lead to the better use of resources, generating the least waste. These changes toward new circular models will only be possible if consumers become involved through their behavior. In this sense, the first step is to understand who pro-circular consumers are and what characterizes them. Thus, this exploratory study aims to profile pro-circular consumers based on their behaviors and to characterize them based on the components of the value-belief-norm (VBN) theory. Using survey data of a representative sample of 417 participants in the city of Medellín (Colombia), as well as cluster and multiple correspondence analyses, this study identified some pro-circular consumer profiles, mainly characterized by factors like moral norms and perceived consumer effectiveness. Our results suggest that even when consumers without habitual behaviors toward circularity exist, those who engage in them do so because they consider it the right thing to do and because they believe that their pro-circular action is effective for solving environmental problems. On the contrary, green consumption values, beliefs about awareness and responsibility toward the environment, and sociodemographic factors do not seem to be associated with and characterize this type of consumer.

Promoting circular business models is a clear path to tackling current environmental and social issues. The success of these models depends not only on companies in charge of creating new products, processes, and models that include circular strategies but also on consumers and their choices. Thus, fully understanding consumers and the factors that influence accepting and adopting practices towards circularity is imperative. One of these factors is the relationship that consumers have with the products they purchase and their assessment of these products through the concept of perceived value. This research aimed to explore the relationship between the dimensions of perceived value (i.e., functional, emotional, and social) and pro-circular behaviors of repair and reuse, as well as the role of green consumption values in this relationship. A representative sample of 417 people was surveyed in Medellín (Colombia). Using an Ordinal Logit model, we tested the hypotheses proposed. Findings reveal that functional value is a primary starting point to encourage behaviors aiming to extend the lifetime of products. Moreover, the interaction between sources of value (perceived value and green consumption values) increases the probability of reusing and repairing. Based on these and other relevant results, managerial implications and opportunities for future research are proposed.

Many ecosystems are facing environmental threats. Some of the main concerns are now focused in developing countries. Strong environmental messages by numerous stakeholders have led to varied responses on environmental issues. Companies, governmental agencies and NGOs are responding to such issues by developing campaigns to promote sustainable practices amongst key stakeholders. Green advertising is one important form of communications employed to elicit environmentally friendly attitudes and consequently promote behavioural change. This study analyses the effect of a sponsored cinematographic green advertising strategy by a NGO and a major supermarket chain in a Latin American country. Based on in-depth interviews with Colombian movie audiences, this investigation demonstrates how (1) a movie focused on nationalistic identification can effectively provoke positive attitude change toward environmental sustainable practices, (2) the movie's media format can heighten audience interest about adopting environmental sustainable practices and (3) these results benefit positively the two movie sponsors through association and affect transfer.
