This work presents a study on the reduction of single-use plastics in a neighborhood delicatessen, based on the application of sustainable accounting principles and Sustainable Development Goal (SDG) No. 12: Responsible Consumption and Production. Using an experimental and mixed-methods approach, direct observations, interviews, and surveys were conducted with owners, employees, and customers. Additionally, intervention strategies were implemented, such as charging for plastic bags, placing informative posters, and promoting reusable bags and returnable containers. The results demonstrated that the combined measures, especially charging for plastic bags and visual awareness, significantly reduced the use of disposable materials and fostered habit changes in consumers. Furthermore, limitations related to the low acceptance of returnable containers due to hygiene concerns were identified. In conclusion, the project confirms the feasibility of applying sustainable practices in micro-enterprises, showing that environmental responsibility and economic profitability can coexist in a complementary way, contributing to the transformation of consumption patterns and the fulfillment of global sustainability goals.

This research addresses the issue of single-use plastic consumption within the university environment and proposes an integrated model that combines economic, institutional, and behavioral approaches to reduce it. The study adopts a quantitative approach based on surveys administered to students, faculty, and administrative staff at the National University of Comahue, particularly within the Faculty of Economics and Administration. Its aim is to identify consumption habits, levels of environmental awareness, and willingness to change.

The results reveal a high level of concern about the environmental impact of plastics and a positive attitude toward adopting sustainable practices, although structural barriers—such as the lack of adequate infrastructure and the persistence of ingrained habits—remain. It is concluded that effectively reducing single-use plastics requires coordination among environmental education, institutional policies, and material resources that facilitate everyday sustainable actions.

This research contributes to the development of strategies applicable in university contexts seeking to advance toward an environmentally responsible culture and more sustainable resource management.

This article addresses the importance of promoting ecological consciousness within the Faculty of Economics and Administration (FAEA) of the National University of Comahue, within the framework of Sustainable Development Goal No. 12: Responsible consumption and production. The main objective was to analyze the impact of an institutional intervention based on the installation of informational posters and awareness campaigns regarding student environmental behavior. A mixed approach was applied, using quantitative and qualitative techniques, and a non-experimental, cross-sectional, and descriptive design. The sample, defined by convenience, included 60 students who responded to digital surveys before and after the campaign. The intervention consisted of posters placed in common areas and publications on an Instagram account. The results showed significant improvements in three dimensions: greater understanding of the concept of responsible consumption, critical evaluation of the impact of plastics, and an increase in sustainable practices such as recycling. The qualitative analysis revealed that visual stimuli generated reflection among students. The discussion links these findings with previous studies on nudges and institutional campaigns, highlighting the effectiveness of simple and accessible strategies. It is concluded that brief and participatory interventions can generate significant changes in university environmental consciousness and strengthen institutional social responsibility.
