Last afternoon, given #DelhiAirEmergency, we gave our employees the option to work from home till 5 Nov, when we will re-evaluate the situation. This thread will explore why there’s no quick fix for India’s #AirPollution woes. #DelhiPollution #Delhi #sustainability 1/n

@KurinjiSelvaraj @tanushree_g @KarthikGanesan6 @hemdholakia @agorthi @guptaniti29 The #airquality has been ‘severe’ (over 10 times above WHO standards for 24 hr mean PM 2.5 concentration) in #Delhi for 7 days. Parts of #India along the Indo-Gangetic plain have also been suffering the same fate. #Lucknow recorded the worst air quality in 3 yrs on Nov 1. 2/n
@KurinjiSelvaraj @tanushree_g @KarthikGanesan6 @hemdholakia @agorthi @guptaniti29 @GhoshArunabha #Delhi has a geographic disadvantage! As winds arrive from the coasts picking up pollutants along the way, they get ‘trapped’ before the Himalayas. This entrapment affects the entire expanse btw Punjab & West Bengal. #DelhiAirEmergency #airpollution 3/n
@KurinjiSelvaraj @tanushree_g @KarthikGanesan6 @hemdholakia @agorthi @guptaniti29 @GhoshArunabha Btw 1-3 Nov, #DelhiAirEmergency did not stop the city from hosting #IndvsBan cricket match, bursting crackers, operating diesel gen-sets on #ChhathPuja & celebrating #thegrubfest. #Delhi needs to rethink on permitting outdoor activities at this time. 4/n
@KurinjiSelvaraj @tanushree_g @KarthikGanesan6 @hemdholakia @agorthi @guptaniti29 @GhoshArunabha Citizens need to take immediate precautions. Follow the #Delhi govt’s health advisory (buff.ly/36FTZ3c).
While stepping out, use certified N95 masks & follow user instructions. Paper & cloth masks are ineffective. Minimise exposure. #DelhiAirEmergency #DelhiPollution. 5/n

@KurinjiSelvaraj @tanushree_g @KarthikGanesan6 @hemdholakia @agorthi @guptaniti29 @GhoshArunabha Remember, at its core, #airpollution is a #sustainability battle. Reducing #cropburning is about sustainable #agriculture, mitigating transport emissions is about #sustainablemobility, reducing power plant emissions is about sustainable #energy systems. #DelhiPollution

@KurinjiSelvaraj @tanushree_g @KarthikGanesan6 @hemdholakia @agorthi @guptaniti29 @GhoshArunabha Due to the prevailing north-westerly winds, the smoke from #stubbleburning in #Punjab is likely to deteriorate the #airquality in #Delhi & it will possibly remain in the 'very poor' to 'severe' categories in the next few days. #DelhiPollution #DelhiAirEmergency 7/n

So, you can’t just blame the farmers: @hemdholakia

Steps must be taken to control construction activities, emissions from stone crushers, hot mix plants, all coal & other fuel-based industries.

While #Delhi reported 'very poor' air quality today, #Kanpur, #Lucknow & #Patna grappled with severe #airquality levels. Delhi’s air quality is likely to be 'very poor' tomorrow too as per forecasts from @UrbanEmissions & @safar.
