Purpose: this study aimed at measuring the sustainable consumption behaviors of generations X, Y and Z using various descriptive variables. Methodology: the convenience sampling method was used for the data of this cross-sectional study collected during March 15-20, 2023, which obtained 244 usable survey data. The data were analyzed using the Statistical Package for the Social Sciences (SPSS) 26. Descriptive statistics and parametric tests were used in the study, such as t, Analysis of Variance (ANOVA) and Pearson correlation analysis. Results: the participants exhibited sustainable consumption behaviors at a moderate level (3.03). Positive and significant relationships (p<0.05) existed between the Sustainable Consumption Behavior Scale and its “environmental sensitivity” (r: 0.789), “saving” (r: 0.725), and "reusability” (r: 0.616) sub-dimensions. There was no statistically significant difference in the sustainable consumption behavior levels of the participants in terms of the variables, such as gender, educational level, income level and family type (p>0.05). However, statistically significant difference existed in the sustainable consumption behavior levels of the participants in terms of the variables, such as marital status, place of residence and generation (p<0.05). Conclusions: married participants living in the city in generation Y exhibited significantly more sustainable consumption behaviors than others. Implications: the study results revealed that the participants did not have sufficient environmental awareness. In this age of continuous consumption, it is of great importance to make necessary efforts on the issue. Within this context, environmental communities and educational institutions should provide more seminars and trainings on this issue.
