Purpose: This paper aims to explain the student-led environmental management system (EMS) based on ISO14001 which Chiba University has continued for 15 years. It describes its structure "Chiba University Method", the students' activities and their collaboration with companies. It also analyzes the advantages and the issues. Readers can reconsider these mechanisms and results to examine whether they could introduce the student-led EMS in their own university. Design/methodology/approach: Four critical points are explained concerning the "Chiba University Method". The advantages are analyzed by the data and the questionnaire survey. Findings: It has been found that student-led EMS has an effect of practical education on the students and an improvement of social evaluation on the university, as well as a reduction of environmental burdens. For students, in addition to the direct merit of obtaining credits, they receive a sense of accomplishment through gaining practical experience, thereby realizing improvements in business skills and making friends through activities. These are good incentives to participating in various activities. However, there are also problems that occur due to student-led EMS, and it is necessary for faculties to be aware and correspond with them. Research limitations/implications: This paper is based on the experience of one Japanese University. Social implications: As this case falls under the practical case of active learning, it is expected that other universities could also introduce this system. Originality/value: It is rare that the students manage the EMS based on ISO14001 with educational effects included in the results. At Chiba University, moreover, students are making environmental contributions to local communities through collaboration with companies.
