Standard system Edit: Some big European and American companies in the 1980s began to develop the company's environmental policies spontaneous commissioned external environmental consulting firm to investigate their environmental performance, and announced the findings (which can be considered the predecessor of environmental audits). In order to prove their good environmental management and environmental performance proud. Their approach has been the public's understanding of the company, also won wide recognition, the company has the appropriate access to economic and environmental benefits. In order to implement this approach, by the end of 1990, Europe has developed two of the scheme, the company provides environmental management approach, it does not have to prove their environmental credentials and act alone. The first plan for BS7750, developed by the British Standards second program is the EU's environmental management system, called the Eco-Management and Audit Act (Eco-Management and Audit Scheme, EMAS), most of its content from BS7750. Many companies these standards after the trial, achieved good environmental and economic benefits. These two standards are better promoted and implemented in Europe. Meanwhile, the rest of the world began to BS7750 and EMAS in accordance with the terms of, and with reference to national standards and regulations, establish an environmental management system. Another action has the basic sense of the world in 1987 issued the first set of ISO management standards --ISO9000 "quality management and quality assurance," a success. Many countries and regions of the ISO9000 series of standards attaches great importance to and actively build enterprise quality management system and access to third-party certification, as one of the international trade advantages to enter the international market conditions. ISO9000 successes prove the feasibility of establishing international standards in management standards and huge progressive. Therefore, ISO on the basis of the successful development of the ISO9000 series, began to develop a standard serial number 14000 series of environmental management standards. Therefore we can say the successful experience of BS7750, EMAS and ISO9000 European countries are actively implementing ISO14000 series basis.
