The Mumbai city authority studies a possible prohibition on vehicles using petrol or diesel fuel to stop environmental pollution and transportation delays while working toward sustainable changes through CNG vehicle programs and electric car initiatives.

Worsening air quality affects the Mumbai Metropolitan Region (MMR) while battling intense traffic congestion among its citizens. Under the directive of the Bombay High Court to strengthen pollution control measures the Maharashtra government established a seven-member committee. The committee will examine whether the city should prohibit petrol and diesel vehicle use to achieve environmental sustainability goals.

The planned transition to CNG and electric vehicles (EVs) represents an attempt to minimize the harmful emissions which drive both Mumbai's declining air quality deterioration and vehicular congestion severity. A three-month deadline hangs over the committee as it examines contemporary vehicle retirement measures just like those implemented by Delhi against their BS3 cars.

The city of Mumbai currently holds 48 lakh registered vehicles while new cars assemble into its streets at a rate exceeding 2 lakh annually. A review of government projections shows that Maharashtra's vehicle population will increase to 6 crore by 2030 which will intensify pollution and driving delays. A government-led strategy to ban vehicles aims to resolve two major environmental concerns.

The ongoing review process indicates promising ideas about reaching cleaner air and decreasing traffic congestion as more cities focus on environmental sustainability in city planning.
