What government is doing to control air pollution in Delhi?

On Friday, the national capital's air quality was recorded in the 'very poor' category, while government agencies said it is likely to improve slightly in the next 24 hours. On Thursday, the city's air quality had dropped to the worst levels since November last year, with farm fires accounting for 42 per cent of its pollution, the maximum this season so far. But political parties are blaming each other for the pollution in Delhi.
