Due to their widespread misuse and inadequate waste management, single-use plastic bags represent the global plastic pollution crisis and ecosystem degradation. Comprehensive research on population knowledge, attitudes, and practices (KAP) regarding single-use plastic bags is lacking in the United Arab Emirates (UAE). This study aims to fill this gap by assessing the KAP levels among the UAE population and determining the relationships between these variables. A five-point Likert scale questionnaire from previous studies was used in a cross-sectional study, and the questionnaire was distributed via Google Forms. The UAE University Research Ethics Committee approved the study (ERSC₂024₄377). Non-probability sampling and G*power statistical analysis version 3. 1. 9. 6 determined 385 UAE residents aged 18 years and older. The findings were verified through face-to-face interviews and Cronbach’s alpha tests. KAP variable associations were assessed using Chi-square tests, Pearson’s correlation coefficients, and a structural equation model with SPSS version 29. 0. This test was chosen for robust categorical and continuous data. The study included 84. 7% female, and 15. 3% male participants aged 18 to 65 years, primarily aged 18 to 25 years, with most holding bachelor’s degrees (47. 6%), and were students (51. 4%), employed (33. 1%), or unemployed (12. 2%). The results indicated a favourable inclination towards sustainability, with mean ± standard deviation (SD) for seven knowledge questions (3. 89 ± 0. 7), seven attitude questions (3. 99 ± 0. 7), and five practice questions (3. 42 ± 0. 8) exceeding the midpoint. The correlation test showed that total knowledge was positively correlated with practice (r = 0. 399; p < 0. 001) indicating the increasing knowledge regarding single-use plastic bags associated with increasing sustainable practices and attitudes (r = 0. 648; p < 0. 001). There was also a significant correlation between the total attitude and practice (r = 0. 487; p < 0. 001). The findings suggest targeted educational and policy interventions to promote sustainable behaviour.
