Union Minister Babul Supriyo said that the annual stubble burning in Punjab and​ Haryana ahead of winter has become “season greetings” to Delhi and also its “capital punishment” as it faces severe air pollution due to it.

However, the “right ways” to combat air pollution in Delhi and other cities have not been implemented, he said at the fifth edition of Indian International Science Festival.

“In Delhi vehicular pollution is less and the smog, which we usually see in pictures and on television is mostly because of the dust, biomass and stubble burning and careless activities by human beings.

“Stubble burning is becoming a season greetings to Delhi and the winds are not helping either … The national capital is going through capital punishment,” he said.
