Beijing became the first Chinese city to impose pollution fees on a new group of airborne pollutants－volatile organic compounds (VOC). “The estimated amount of fees to be collected annually is between CNY1 billion and CNY2 billion, about half of which may come from southwest Beijing’s Fangshan district, where the city’s biggest VOC emitter, Sinopec Beijng Yanshan Co, is located,” said Wang Hailin, Researcher at the Beijing Research Institute of Environmental Protection. Currently, pollution fees are charged for more than 40 types of airborne pollutants, including sulfur dioxide, nitrogen oxide and carbon monoxide. VOCs are mainly generated by the petrochemical industry, organic chemical industry, during the production of plastic products, and in the packaging and printing industry. It enhances the oxidation of the atmosphere, which facilitates the forming of more pollutants, and is also a premise for the formation of PM2.5. “China has the largest VOC emissions in the world, and they are also growing quickly,” said Yang Jintian, Dean of the Atmospheric Environment Institute at the Chinese Academy for Environmental Planning. He said there is no official data for the exact amount of VOC emissions, but they are estimated at about 25 million metric tons a year.
