New Delhi: The Society of Indian Automobile Manufacturers (Siam) on Friday said implementation of the new emission norms scheduled to be effective from 1 April should be postponed by up to six months if there is no clarity on availability of upgraded fuels latest by January-end.

“Siam has already made representations to the government that if fuel is not available, then implementation of the new emission norms should be postponed by three-six months in those regions where fuel is not available or across the country," he added.

Starting April, 11 cities across India, where the Bharat Stage (BS) III norms are currently in place, are supposed to upgrade to BS-IV, and the rest of the country where BS-II norms are followed are to move towards BS-III norms.

There should be a clarity latest by January-end on the fuel availability, otherwise it would be difficult for the industry to revert to the old emission norms standards, Goenka said.

“After 31 January, it will be difficult for us to revert, although it is not impossible," he said, while not elaborating what additional costs the industry would bear if it has to go back to the old norms.

“The industry is ready to meet the new emission norms deadline and many companies have already started putting in toolings for the purpose," he said. Siam had asked the Centre to give a clear picture by 31 December 2009.
