Environmental management principles specify policies, procedures, and audit protocols for controlling operations that create waste materials or emissions (Matthews, 2003). These principles usually take the form of standardized EMS such as British Standard for EMS BS7750 (1994), the EU eco-management and audit scheme (1993), and the international standard ISO 14000 (Bansal &Clelland, 2004). These standards have been developed to provide organizations with a framework to implement EMS (Netherwood, 1996).
