Ye Diwali, Khushiyon wali – Apnon wali – Pollution wali

Diwali, a festival every Indian looks forward to. New clothes, sweets, diyas and firecrackers combined with the holidays of schools, colleges and offices enlighten the enthusiasm in every member of the family. We have been celebrating it this way since childhood and will definitely not be comfortable if someone asks us to not burst crackers on Diwali.

Despite the apex court ruling in 2018 to ban bursting of polluting firecrackers and allowing green firecrackers, that too from 8 PM to 10 PM, NCR residents witnessed the most unacceptable limits of air pollution this Diwali.

As per the data reported by the pollution sensor installed by ZunRoof in sector 56, Gurugram, the AQI on this Diwali (27th October 2019) was between 163 and 384 till 7 PM. Unsurprisingly, from 8 PM to 9 PM the AQI was between 352 & 562, the next hour it rose to 557 & 733 and from 10 PM to 11 PM the AQI ranged 757 to 878. 

An AQI between 0-50 is considered “good”, 51-100 “satisfactory”, 101-200 “moderate”, 201-300 “poor”, 301-400 “very poor”, and 401-500 “severe”. Above 500 is “severe-plus emergency” category. This Diwali, Gurgugram’s AQI was already very poor and it was further degraded to the severe-plus emergency category.

ZunRoof, a clean energy company that offers solar rooftops to residential customers for generating clean, smart and free electricity utilizing their roof, installed 15 pollution sensors last year across Gurugram.
