China's Hebei Province issued an orange warning, the second most serious air pollution level, when haze appeared dense.

"Unfavorable weather conditions with rising humidity and weak south winds will make the haze diffuse more during this period," Hebei Department of Environment, China's leading steel-making province, announced today. advise.

Orange warnings are the second highest in China 's haze and air pollution warning system, saying pollution is "serious", just after the red warning. Hebei Department of Environment said this level of alert takes effect from the beginning of next month.

When the orange warning goes into effect, companies that are not on the "positive list" of environmental compliance will have to close or cut production. Companies on this list are also encouraged to voluntarily cut emissions.

According to data published last week, Hebei is the province with 5 out of 10 cities with China's highest haze pollution in the first three quarters of this year. The provincial government pledged to severely punish officials responsible for environmental issues and increase pollution control measures.

China, for nearly three years, has taken drastic measures to control winter air pollution, but it seems that the goal has not been reached. Up to 15 of the 28 cities around the Beijing - Tianjin - Hebei region still experienced more severe smog than two years ago.

Chinese Ministry of Ecology and Environment Liu Youbin said on October 29 that the country was still determined to cut down on haze pollution in the winter to protect the environment, but he warned that weather conditions were less windy. This year could be detrimental to these efforts.
