Despite years of anti-cracker awareness programmes pollution in Delhi has been increasing every year over the past five years.
The pollution figures start to increase at around 6 pm on the day of Diwali and tend to peak between 10 pm and midnight.
“We have observed that despite several appeals for all these years have had almost no effect. The pollution figures clearly indicate that the pollution has been rising. The awareness is t but it has not translated into action,” said Delhi government environment secretary, Ashwani Kumar.

“The one way that I see to control the pollution is to put a cap on the supply of fireworks since the demand shows no signs of abating. It is too late to try this strategy this year as the stocks are already in place,” Kumar said.
The authorities have passed, as in the past, guidelines to block the sale of Chinese crackers that are of poor quality, are not regulated by Indian standards and tend to violate norms relating to noise pollution when compared to the ones made in India.
