Calcutta, Oct. 17 :    Calcutta, Oct. 17:  The state government is firm on implementing the Euro II auto emission norms in Calcutta from November 1. At a meeting on Tuesday with representatives of Indian automobile manufacturers at Writers' Buildings, the government informed them that there is no question of extending the November 1 deadline if the required fuel with a sulphur content of not more than .05 per cent of sulphur is available. At present, there is about .25 per cent of sulphur in petrol and diesel and the lower percentage of sulphur will ensure lesser pollution from automobile emissions. Vehicle manufacturers urged the government to extend the deadline.The meeting, chaired by chief secretary Manish Gupta, was attended by environment secretary Kalyan Bagchi and transport secretary D.M. Kanwar. Official sources said the environment department had already contacted Indian Oil Corporation, inquiring whether it would be able to supply petrol with a .05 per cent sulphur content. Sources said Bagchi told the automobile manufacturers that the IOC had assured the government that there would be no problem in supplying the requisite fuel. 'If the required fuel is available, there is no reason why Euro II norms will not be made applicable for Calcutta from November 1,' said Kanwar. Sources in the automobile industry said that there would be a problem of disposing the existing stock of unsold cars, which do not conform to the Euro II auto emission standards. Moreover, sales tax on vehicles stocked in different city showrooms had already been paid, they added. 'Also, to instal equipment to conform to Euro II standards, the prices of cars will go up by at least Rs 15,000. This will have an adverse impact on buyers,' an automobile dealer said. Calcutta is the second metro after New Delhi to implement Euro II norms. After Calcutta, the standards will be made compulsory in Mumbai and then in Chennai in 2001.
