Bhartiya Janta Party MP from Delhi Parvesh Verma slammed Chief Minister Arvind Kejriwal for saying that biomass burning by security guards and drivers is one of the sources of pollution in the national capital. Speaking at the event, Kejriwal stated that biomass burning accounts for one-fifth of pollution in the state, which increases significantly during the winter when security guards and drivers burn wood and other biomass, causing the city to become a gas chamber owing to temperature inversion.
