Increasing BS-IV coverage to cost Rs 150 bn for oil cos

In order to bring 50 cities under Bharat Stage (BS)-IV fuel norms by 2015, oil majors have to invest Rs 15,000 crore in their refineries. Currently, 16 major cities have been brought under the latest emission norms. However, the adoption of the new norms by existing fleets would be a challenge. Oil companies had invested nearly Rs 30,000 crore in the last few years at their refineries to manufacture fuel that complied with BS-IV norms, instead of BS-III. An additional investment of Rs 10,000-15,000 crore is still needed.
