Two quality management standards exist in Europe for the management of environmental issues in an enterprise. The Environmental Management and Audit Scheme (EMAS) is a European Union policy instrument to foster the implementation and auditing of environmental management in industry. The other is based on the International Organization for Standardization (ISO) (and CEN) 14001 standard. Both the EMAS and the ISO standards are voluntary schemes.
Some European countries have defined standards for occupational health and safety management systems to be used either by enterprises themselves or by the occupational health services (the United Kingdom uses BS 8800, the Netherlands NPR 5001, Spain UNE 81900-81902, and the German Land of Hessen the ASCA system). The WHO Regional Office for Europe has also developed guidelines on quality management in occupational health services.
