A Vehicle Emission Tax Model: To Promote Adoption of Zero Emission Vehicles for Indian Context
Abstract: Vehicle tailpipe emissions have been regulated by the authorities over the period of time forcing vehicle manufacturers in improving engine technologies to comply with the government stipulated norms. Improvement in engine designs has reduced vehicle tailpipe emissions to the extent of emissions to meet the notified norms. Historically, such a reduction in vehicle emissions has been achieved in steps/stages as and when new emission norms were notified. It is proposed …
