Zheng Guoguang, director of the China Meteorological Administration (CMA) denied the argument that China's artificial snow will pollute the environment. He said that China's artificial snow can have an input-output ratio of one to 50.

Zheng Guoguang emphasized that China's artificial snow mainly uses dry ice, liquid nitrogen, silver iodide and other catalysts with high ice capability. Dry ice and liquid nitrogen vaporize into carbon dioxide and nitrogen, which are part of the air and will not cause pollution. A small amount of silver iodide will not pollute the environment.

Zheng Guoguang said that China's artificial snow is mostly used in hired aircraft. In addition, by strengthening management and training, we can minimize the possibility of security incidents of making the artificial snow. Zheng Guoguang also said that in the next few months, the meteorological department will continue to organize and arrange the artificial snow.
