Kolkata joined the league of cities having clean automotive fuel on Monday with the commercial launch of two CNG pumps, officials said.
While Indian Oil Corp set up a pump in New Town, the other was launched by BPCL in Garia, they said.
The CNG is being supplied by the Bengal Gas Company, a joint venture between GAIL and the West Bengal government.
The Bengal Gas Company has installed the dispensers, while the oil marketing companies have provided space and other infrastructure, officials said.
Another five-six CNG pumps are expected to be unveiled very soon, they said.
