Environmental education plays a crucial role in developing students' critical awareness, yet effective learning approaches remain a challenge in high schools. This study examines the impact of the Project Based Hybrid Learning (PJBHL) model on developing critical environmental awareness among high school students. The research utilized a quasi-experimental design and included a sample of 66 students from the State Islamic Senior High School (MAN) 5 Jombang, Indonesia. The experimental group engaged in a PJBHL model focused on creating products from recycled plastic materials, while the control group used traditional methods. Data was collected through pre-test and post-test questionnaires evaluating critical environmental awareness. Results from independent T-tests and N-Gain analysis revealed that the PJBHL model significantly enhanced students' critical environmental awareness compared to conventional methods. The experimental group showed an increase in all sub-indicators of environmental awareness, with environmental ethics achieving the highest score. The study suggests that the PJBHL model is an effective technique for promoting critical environmental awareness among high school students. This finding offers insights for teachers to enhance environmental education and encourage sustainable activities in high schools. © 2025 The authors.
