Mumbai is one of the largest cities of the country and in which, a large number of vehicles everyday create heavy pollution. Due to this reason, ‘pollution-free BEST’ buses were launched, for which a provision of ₹10 crores was sanctioned at the municipal budget. Similarly, 6 buses were bought that were battery-operated from Goldstone Infratech. With the initial buses running only in Fort area in Mumbai, slowly the number will keep increasing and reaching more areas of the city. Due to this, pollution is slowly reducing and these buses are being seen as an alternative to fuel driven vehicles.
