Publisher Summary This chapter focuses on project planning by considering the logic of creating a program that includes initiatives ranging from the initial decision to create an Environmental Management System (EMS) to its successful assessment by International Organization for Standardization (ISO) 14001. The program has 11 steps, which includes commitment, resources, communication, environmental legislation and environmental aspects, management objectives and policies, procedures, writing manual, implementation, auditing, choosing assessor, and assessment. A supplier has a process to ensure compliance with all applicable government safety and environmental regulations, including those related to handling, recycling, eliminating, or disposing of hazardous materials as expressed in the QS 9000 standard. Project Acorn, a pilot study, was done jointly by the British Standard Institute (BSI) and the Department of the Environment, Transport and the Regions (DETR), which started in mid-2000, involving some large companies and their suppliers. The reason for creating an environmental management system is to stay within the law by knowing what impact activities have on the environment and taking active steps to reduce the impact.
