Delhi government have been boasting about the success of off-even scheme but was it really a success? If you go by the study of the Indian Institute of Technology (IIT), Kanpur, conducted on behalf of the government, you will know that it wasn’t a well thought of plan. Why you may ask?
The odd-even rules was mainly focused on four wheelers but cars are not the primary polluters in the Delhi and contribute a mere one percent of the Particulate Matter-PM 2.5 concentration. The study also points out that 38% of PM 2.5 pollution comes from road dust and only 9% comes from vehicles. OF the vehicles, 46% of pollution is caused by trucks, 33% is caused by two-wheelers, while diesel four wheelers only contribute 10% which is less than 1% of total pollutants.
Delhi government kept two-wheelers from the regulation even though two-wheelers contribute between 40-60% of the total pollution from the vehicles. Even auto industry experts agree that even though emission by two-wheelers might be less than cars but there is more number of two-wheelers on road than car. 1.8 lakh four wheelers were sold in Delhi in 2015 and 3.8 lakh two-wheelers were sold, which is almost double. Exempting two wheelers from the odd-even scheme is one of the reasons that it didn’t work out.
Talking about four-wheelers in Delhi, Chairman of Maruti Suzuki, RC Bhargava stated that 80% of cars in Delhi were petrol which doesn’t emit PM pollutants, only 20% diesel cars emit PM. It can’t be explained why Delhi’s government didn’t exempt the petrol cars.
Delhi is one of the most polluted city in the world and it’s pollution problem isn’t going to get solved just by controlling vehicles on the road. The major reasons for pollution in Delhi are old busses and trucks, diesel tempos, dust particles, diesel generators, thermal power plants and diesel machinery at construction sites. However the regulations were mainly on auto-mobiles instead of other sources of pollution that emits more PM. Hope Delhi government has learned their lesson and will plan better in the future.
