This article is based on the perception that nowadays in different spheres, whether economic, political, social or environmental, ethics and sustainability are discussed. Worryingly, there is a need to establish and consolidate ethics among women, particularly those who carry out commercial activities in the informal market, so that environmental sustainability can be achieved. Therefore, the present research has the general objective of analyzing what has prevented the affirmation of ethics by sellers for the environmental sustainability of the Cabassango market. Thus, exploratory and bibliographical research was used as methods, the hypothetical deductive and statistical method, the questionnaire technique was applied to 80 women salespeople and the semi-structured interview technique was applied to 4 market managers, of whom 3 were male and 1 was female, a systematic observation was also carried out, the data was treated statistically using SPSS software. It was found that the majority of sellers have complied with ethical principles, but this has not contributed satisfactorily to environmental sustainability, as the 80 women surveyed, which corresponds to 100%, stated that they use plastic bags, which has encouraged their customers buying more plastic bags and who are unaware of the damage that plastic bags cause to the environment. Therefore, it was concluded that sustainable actions have not been implemented in the market, which has prevented the sellers from affirming their ethics towards environmental sustainability in the Cabassango market.
