Yeah I also read those articles but that might be due to some other reasons,it is very much understandable that how can pollution be increased when number of cars on the road is cut to half
It was due to some other reasons,Odd Even can't increase pollution :shy :hehe
Bro Cars only account for 11 % pollution.A Diesel bus which is substitutes car causes 50 times more polution than a petrol car.So pollution will always increase.
But one bus can carry 80-100 people where as most car carry 2-3 people so consider it also in your pollution calculation and As per my view there are very few buses on Delhi Road compared to Mumbai or kolkata
