The province is also giving coke producers until Oct. 1, 2019 to meet stringent environmental standards, according to the statement, with those missing the deadline facing the prospect of being ordered to shut down, Reuters reported.
The statement came after all 11 cities in Shanxi were identified this year by central government as ‘key battlefield’ of the country's steadfast anti-pollution campaign.
It has vowed to cut sulfur dioxide and nitrogen oxide amount by more than 20 percent by 2020 from the level in 2015, according to a separate document issued by the provincial government in July.
The province has been heavily relying on mining and processing of the polluting fossil fuel, with one-fifth of China's total coke output coming from Shanxi last year.
Currently, Shanxi has around 130 million tons of coking capacity, according to analysts estimation.
"We will use environmental, energy efficiency and safety measures to force companies to phase out outdated capacity," said Shanxi government in a statement, also ordering city authorities to form capacity elimination plans by the end of 2018.
