<h1>Vehicle electrification could cut urban air pollution and greenhouse gases while reducing oil import dependence and creating jobs.</h1> Replacing older vehicles with electric vehicles in 44 cities could significantly cut daily PM2.5 and greenhouse gas emissions, displace large volumes of petrol and diesel to reduce the oil import bill, and necessitate extensive EV charging and vehicle scrapping infrastructure; full electrification yields substantially greater emissions reductions and job creation than a mixed EV-CNG approach.
