CNG filling stations in India in

Regulatory and judicial mandates have created opportunities for CNG programmes in Indian cities. The Delhi and Mumbai CNG programmes are the oldest and most established in India. Mumbai's programme was initially driven by public policy and also by the commercial interest of the large taxi fleet. commercial interest of the large taxi fleet for a CNG fuel substantially cheaper than petrol, which was their main fuel in the city. Much later, the Bombay High Court stepped in to order the conversion to CNG of the city's cargo vehicles as a pollution control measure.

In January 1998, the Environment Pollution Prevention and Control Authority was set up under the Environment Protection Act to advise the court on pollution control measures and also monitor the implementation of court orders. Since then, a number of judgments on CNG and other vehicle pollution control measures have been passed in Delhi.

The next big challenge is to create an adequate refuelling infrastructure in the new cities. This will require planning and implementation of an adequate network. Therefore, the question arises as to how the CNG network can be made profitable for transport with a suitable business model in the new cities. And for this the Government of India through the "Blue Sky" programme continues to support the installation of CNG stations for public supply.

In India there are currently more than 3000 CNG refueling stations open to the public.
