In , when the Central Pollution Control Board released its study of 22 polluted cities, Delhi appeared to be breathing easier. Soon enough, more vehicles converted to CNG than the government had anticipated. This caused some trouble as the limited number of gas stations meant that users sometimes spent more than 10 hours in queues to fill gas.
It fined the government Rs 1, per day per diesel bus that was still on the streets. By December that year, the last diesel bus was taken off the roads, and the national capital ended up with the cleanest public transportation system in the world. The switch to CNG showed significant results, at least initially.

Foreign experts were called in to examine the problem[2], and a new regulation on CNG safety was published. One main problem was the absence of stress relief loops on CNG installations — a problem not limited to CNG and India, which led to the banning of LPG cars in Europe not equipped with pressure relief equipment.
A further conversation of the approximately 1 million automobiles is hindered by the limited supply of CNG gas. Nevertheless, new three-wheeler commercial goods vehicles also have to run on CNG. And many white Ambassador cars for tourists have been converted to dual use, running on CNG in Delhi and on gasoline outside Delhi. A new pipeline network is under construction, linking the Gujarat coast with major cities in the west of India.
The import of CNG and increased production will overcome the supply shortage. In addition, new natural gas fields are developed in Gujarat and will come into production. Also, the import of CNG by ship will increase in the future. The biggest problem are transit trucks, which are still allowed in Delhi at night.
