Delhi Environment Minister Manjinder Singh Sirsa stated, "...After March 31, fuel will not be provided to vehicles older than 15 years. There are several large hotels, major office complexes, Delhi Airport, and significant construction sites in the city. We will make it mandatory for all of these entities to immediately install anti-smog guns to control pollution at their locations. Additionally, we will require all high-rise buildings in Delhi to install smog guns. The same applies to all hotels and commercial complexes in the area.
