New Delhi: Taking a dig at carmakers lobbying for CAFE-3, the next phase of fuel efficiency norms, Road Transport Minister Nitin Gadkari on Tuesday said they are trying from behind the scenes to influence the policy and are not exposed like political leaders.He also indicated some similarity in the criteria for flex-fuel hybrid cars with EVs.Speaking at the Indian Federation of Green Energy’s Green Transport Conclave, Gadkari said, “The file (on CAFE-3) will come to me in the next 15 days. I don’t want to say what has happened. There have been controversies. In politics, we get exposed because we are 100% open. Industries are not exposed because they do publicity on the back.”Meanwhile, TOI has learned that auto industry body, SIAM, has written to Power Secretary Pankaj Agarwal demanding an increase of Rs 4 for EVs, three for range extended electric vehicles and plug-in hybrid electric vehicles and 1.5 for flex-fuel vehicles. Car makers have also urged the government to allow credit points to be carried over to the next two-year block for meeting emissions and energy efficiency targets for the first three years.CAFE-3, which will be in effect for five years, proposes pooling of compliance among manufacturers and rolling out the credit within the bloc – initially for three years and then two years. Any surplus credits will expire at the end of each block.As of now, carmakers have officially said that they are on board with the latest version of the government’s CAFE-3 proposal.
