Environmental Management System
ISO 14001:2004 does not specify levels of environmental performance. If it specified levels of environmental performance, they would have to be specific to each business activity and this would require a specific EMS standard for each business.
ISO 14001 is not a technical standard and as such does not in any way replace technical requirements embodied in statutes or regulations. It also does not set prescribed standards of performance for organizations.
The EMS requirement is designed to point out the delicate balance between maintaining profitability and reducing environmental impact; with the commitment of your entire organization, it can enable you to achieve both objectives.
