The Ministry of Environmental Protection first issued the national environmental protection standard

On April 14, the Ministry of Environmental Protection and the State Administration of Quality Supervision, Inspection and Quarantine jointly issued four national pollutant discharge standards. This is the first time that the Ministry of Environmental Protection has issued national environmental protection standards since its establishment. According to the person in charge of the Ministry of Environmental Protection, the introduction of four standards will further increase the level of emission control of pollution sources and improve the national pollutant discharge monitoring system.
The four standards are the "CBM (Coal Mine Gas) Emission Standards (Interim)", "Household Waste Landfill Pollution Control Standards", "Heterocyclic Pesticide Industrial Water Pollutant Emission Standards" and "Heavy Duty Gasoline Engines". Emission Limits and Measurement Methods for Vehicle Exhaust Emissions (Chinese Phase III, IV).
According to reports, the "CBM (Coal Mine Gas) Emission Standards (Interim)" issued this time requires that "high-concentration gas with a methane ratio of more than 30%" be prohibited from being discharged. This is the world's first national standard for the control of greenhouse gas emissions that is enforced. It has demonstrated to the international community China's efforts and responsible image in response to global climate change.
It is reported that if 80% of the high-concentration gas in the existing mines in the Mainland is used, the annual gas utilization will be 820 million m3, equivalent to 4.63 million tons of standard coal, and will directly promote energy-saving and emission reduction. After the implementation of the standard, the annual gas emission reduction is expected to be 2.5 billion m3 and the CO2 equivalent is 37 million tons.
Among them, the "Discharge Standards for Water Pollutants of Heterocyclic Agrochemicals Industry" is the first national emission standard for pesticides that was introduced after the Ministry of Environmental Protection initiated the formulation of the discharge standards for water pollutants from pesticides.
