Background: Environmental schools (green schools) are international programs related to environmental education, sustainable development, and environmental management. The main objective of the present study was to evaluate the impact of the environmental performance of the students in improving the green school indicators as a perspective of sustainable development.
Methods: The present study was performed on Bahabad school students (Yazd province) in 2023-2024. The environmental performance questionnaire was researcher-made, and its validity and reliability were evaluated. Cronbach’s alpha was used to calculate the reliability coefficient of the questionnaire (0.7). The Kruskal-Wallis test and the Spearman correlation test were used to examine significant differences between groups and to determine the important relationship between variables.
Results: The results of this study showed that only 12.3% of schools were first-class schools. There was a significant relationship between the environmental performance and improvement of indicators of green schools (P < 0.05). Also, educational level played an important role (P < 0.05) in the environmental performance and green schools improving indexes, while there was no relationship as a gender variable
(P > 0.05).
Conclusion: The green school grade had a direct relationship with the students’ environmental performance. The first-grade green schools have the highest score in the students’ environmental performance, which means that the students of schools that were closer to the standards of green schools, have an important role in improving and protecting the environment and had higher scores in locations that were different environmental dimensions (transportation, waste separation and green shopping, saving water).
