Is there any other Environmental Management System in operation besides ISO14001?

Two more Environmental Management Systems are operating in Europe. These are Eco-Management and Audit Scheme (EMAS) operating in European Union since 1993 and BS 7750 operating in United Kingdom (UK) since 1992. After introduction of ISO 14001, BS 7750 has been withdrawn. ISO 14001 standard is developed based on BS 7750. Both EMAS and BS 7750 are stronger than ISO 14001 but out of the two, EMAS is much more stringent. To adopt EMAS, an enterprise has to meet many more conditions than the ones required under ISO 14001.
