Pollution problem due to Shared Auto Rikshaw - Pune city

I would like to highlights severe pollution problem due to shared auto rickshaw that run every day from pimple Saudagar to hinjewadi area. As we all will agree on the fact, these vehicles are producing highly toxic/black exhaust and responsible for big share of pollution. One side we have green buses running on CNG, on traffic rule violation, first question traffic police officer ask is, where is PUC ?, all car are compliance to some Bharat Std. and same time we have such transport mechanism in city which really destroying city climate. My sincere request to you is only allow such transport mechanism, if they clear PUC certificate.
