Goswami has also sought a direction that every fuel invoice should specifically and legibly state the percentage of ethanol in the petrol sold. "Direct the respondents (Centre and others) to prepare and publish within a stipulated time an official, public, vehicle-wise compatibility database searchable by manufacturer, model, engine type and year of manufacture, indicating the suitability or otherwise of various ethanol blends for each vehicle," his plea said. It has also sought the constitution of an independent expert committee comprising representatives from the ministries of petroleum and natural gas, road transport and highways, the Bureau of Indian Standards and others, including independent automobile engineers, to examine and submit a public report on real-world vehicle compatibility of E20 across the existing fleet. The plea said the committee should also submit a report on the impact on fuel efficiency, engine longevity and maintenance costs, warranty and insurance implications, the net environmental footprint, including tail-pipe emissions and water consumption associated with ethanol production, and food-security and feed-diversion concerns allegedly arising from the blending programme.
