The instrument was adapted from character education indicators by Ministry of Research, Technology and Higher Education and the combination of sustainable development learning indicators. The result shows that mostly the character aspects of Indonesian golden generation can be enhanced. ESD character model can develop several characters of students but still need more time to enhance student’s critical attitude and creativity. Besides, it can inferred that implementation of ESD in science education, biology, physics, and chemistry subject can be recommended by using several learning models, of which one of them is ESD character model.
