Knowledge and skills related to environmental protection are in high demand for any workforce that is both aware of and competent in its actions. Continuous optimization and reform of production structures are essential procedures for ecology-geared corporate processes; therefore, corresponding training for all members of the workforce, from skilled workers to management, is a key factor in making this continuous improvement process possible. In many cases there is a lack of teaching and training materials directly related to business operations. Therefore, teachers and trainers frequently face the problem of how to integrate the issue of environmental protection in the instruction they provide in college or the workplace. As a response to this problem, an interdisciplinary concept for environmental education was developed in the former East Germany to support teachers and trainers in their efforts to integrate sound environmental practices into initial vocational training in a systematic and practical manner. The concept was implemented in the form of manuals on environmental education relating to the following: industrial metalworking occupations, sanitation, heating and air conditioning engineering occupations, construction occupations, motor vehicle occupations, and chemicals occupations. The manuals can be adapted for use by various companies and used for online training. (KC)
