The Supreme Court has allowed bursting of green crackers for two hours on Diwali. Other festivals included in the order are Chhath Puja, Gurupurab, Christmas and New Year. However, the order is applicable in cities where the air quality is moderate or below (better). The SC order is being seen as a major relief to the firecracker industry. Delhi and other cities in NCR will still be subject to firecracker ban. This is because Air Quality Index in these cities are in poor, very poor or severe categories.
