However, the use of low-sulphur coal in thermal power plants is allowed, the central government's Commission for Air Quality Management said (CAQM).
The ban is part of a comprehensive policy released by the CAQM in July last year. The policy lists sector-wise action plans to curb air pollution in Delhi-NCR in the next five years.
A CAQM official said, "Pollution control authorities have been directed to close down industries and commercial establishments using unapproved fuels, including coal, without giving them any show cause notice."
"Maximum environmental compensation will be levied on them according to the guidelines of the Central Pollution Control Boards," the official added.
He said the panel had announced the ban six months ago, giving enough time to all industries to shift to cleaner fuels, as per PTI reports.
The use of low-sulphur coal is also allowed in captive thermal power plants, the official clarified, saying "it could be used wherever the primary purpose is power generation".
Firewood and biomass briquettes can be used for religious purposes and cremation, wood or bamboo charcoal can be used for tandoors and grills of hotels, restaurants, banquet halls (with emission control system) and open eateries or dhabas.
The use of wood charcoal for cloth ironing is allowed, the CAQM had said earlier.
The commission had in June issued directions to ban the use of coal in industrial, domestic and other miscellaneous applications in the entire Delhi-NCR region from January 1, 2023.
Around 1.7 million tonnes of coal is used annually in industrial applications in NCR, with about 1.4 million tonnes being consumed in six major industrial districts alone.
