Maharashtra Forms Committee to Study Possibility of Mumbai Banning Petrol, Diesel Vehicles
The Maharashtra government has formed a seven-member committee to study whether the MMR can ban petrol and diesel vehicles to control the increasing level of air pollution. It will check whether the city can allow only CNG and electric vehicles.
Committee to Submit Report in Three Months

According to a government resolution (GR) of January 22, the committee comprises former IAS officer Sudhir Kumar Shrivastava, among others. He is:
Maharashtra transport commissioner
Mumbai's joint police commissioner (traffic)
Managing director, Mahanagar Gas Limited
Project manager, Maharashtra State Power Distribution Company Limited, also known as Mahavitaran
President of the Society of Indian Automobile Manufacturers (SIAM)
Joint transport commissioner, enforcement-1, as member secretary.
The committee will consult other experts if need be and will also take views before arriving at a decision of the report to be presented within three months.
High Court Censures Pollution and Traffic

This move comes after the Bombay High Court criticized on January 9 the worsening air pollution and traffic congestion in Mumbai. It pointed out that the measures adopted for controlling vehicular pollution were not adequate and this further had an adverse impact on the environment and quality of life.
The level of air pollution has risen in the city of Mumbai, and the chief culprit is exhaust from vehicles. The High Court felt that such a study must be comprehensive enough to answer the question whether petrol or diesel vehicles are to be phased out completely.

Vehicular Emissions Held as the Critical Pollutant

In 2021, the MPCB had constituted a committee headed by Satish Sahasrabuddhe, former additional transport commissioner to formulate draft policies to reduce emissions in road transports of MMR .
The report of the committee had given the results as follows
The vehicle number in MMR increased at 15.95 percent compound annual rate over the past decade .
In Mumbai, there has been 2.6% increase of PM2.5 since 2019
Vehicular emission has been the second largest source of emissions, following that of road dust.
Transport emissions containing chemically reactive particulates that are smaller than 0.5 microns trigger extreme health issues.
Poor Air Quality Index Brings in the Requirement
On January 29, the India Meteorological Department released an Air Quality Index for Mumbai, which surprisingly came out to be "poor" with 267 levels of deteriorating air quality. It shows a humongous urgent requirement of proper pollution control measures.
Effect on Vehicle Owner and Transition Plan This would involve a strategic approach toward the infrastructure of charging stations and refueling ones. Of major concerns, it would involve implication for the wallets of the existing users of the old stock of vehicles and time required for a full transition to newer greener modes. The economic and logistics issues have to be borne in mind before making a final call, the Maharashtra government since the committee report is likely to submit its suggestions to the government.
