According to the result of our research, we found that all of the country had a standard gas management system to support the environment protection business. They had the regulation to control the exhaust emission and energy consumption, according to the air-quality monitor and stationary and mobile emission law. All of the installed gas monitor and analyzer could continuously execute the legal measurement, if they had been periodically calibrated with traceable standard gas after qualified verification in the period if the time. All of the problem of the traceable administration and quality supervision would occur in the view of the environment-protection execution, if we don’t have the perfect traceable certificate system of the environmental gas standard and registration and inspection and after-the-market-management. All of the country have a metrology system combined environment-protection code to support the traceable requirement of the standard gas for the regulation control of the environment-protection. For example, US EPA made the EPA Protocol gas system to get the traceable and standard requirement for the audit control. Japan use the JCSS quality system to make a registration and inspection system. China also built the CNRM registration platform through the metrology system. Because of the extensive and quantitative usage of standard gas in the test and monitor field of the environmental air pollution, we could enhance the credibility of the execution and check for the regulation and conformity of the auditing standards, even the promotion of the economic development for the domestic gas-related industries, if we could build the TEPA protocol gas registration platform with international standard.
