Sustainability consciousness is an outcome of Education for Sustainable Development, which was launched by UNESCO in 2014 to create a society with sustainable living behavior. The purpose of this research is to analyze the impact of the RADEC learning model oriented ESD on students' sustainability consciousness. This research involved 150 elementary students from 6 districts of Bogor city in Indonesia. The participants' age range was 10-11 years, while the study duration was 2 months and from the 5th grade. The sampling technique used was purposive random sampling. This study used a pre-experiment with pre-post test design. The data were collected by giving a development questionnaire of sustainability consciousness which was adapted from Gerick et al (2019). The questionnaire consists of 27 statement items. The results showed that (1) there was a difference in the sustainability consciousness of students before and after being given the RADEC learning model oriented ESD, this was indicated by sig (0.000) < (0.05); (2) The average sustainability consciousness of students after being given the RADEC learning model integrated ESD for sustainability knowingness, sustainability attitude and sustainability behavior (4.42, 4.72, 4.35) is higher than the average sustainability consciousness before being given the RADEC learning model integrated ESD for sustainability knowingness, sustainability attitude and sustainability behavior (3.24, 3.51, 3.18); (3) Aspect sustainability behavior having medium category and for aspect sustainability knowledge and sustainability attitude, same have high categories. Based on the results, we can see that RADEC learning model-integrated ESD can help students achieve a higher proportion of sustainability consciousness in all aspects. The recommendation for this research is that teachers can design and implement an ESD-oriented RADEC model that facilitates students to develop sustainable consciousness skills effectively.
