Feb 28: National oil marketer Indian Oil Corporation (IOC) on Friday said it is ready to supply low emission BS-VI fuels from April 1 and that there will be a marginal increase in retail prices.

The largest oil supplier has spent over Rs 17,000 crore to upgrade its refineries to produce the low-sulfur diesel and petrol, the company's chairman Sanjiv Singh told reporters here.

Without disclosing the quantum of price increase, Singh said, “there will definitely be a marginal increase in retail prices of the fuels from April 1 when the whole country will be run on new fuels, which will have a sulphur content of only 10 parts per million (ppm) as against the present 50 ppm.

“But let me assure you, we will not be burdening the consumers with a steep hike,” Singh said.

He said, state-run oil marketing companies (OMCs) have invested Rs 35,000 crore to upgrade their refineries, of which Rs 17,000 crore have been spent by IOC alone.

Earlier this week, the sell-off bound BPCL said it had invested around Rs 7,000 crore for the same. ONGC-run HPCL has not so far disclosed its readiness for BS-VI supplies or its capex on the same.

HPCL had said from February 26-27 it was ready with BS-VI fuels and that it would sell only the new fuels from March 1.

IOC switched to BS-VI fuel production a fortnight ago and all its depots and containers are ready now, Singh said.

However, he said some remote locations, where the intake is very low, will take some more time to switch. But the company is planning to drain out the entire BS-IV stock and replenish the new fuels at such locations, he added.

Further, it has been reported that the companies will have to increase prices by 70-120 paise a litre, but Singh said, to arrive such a weighted average is not possible given the complexities of each refinery.

He, however, asserted that the price hike will not be a burden on consumers.

We are not looking at this investment from a pure return on investment basis, but this is a national mandate and we have done it.

Having said that, all those countries that moved to low emission fuels are charging higher prices; and from April 1, our prices will also be benchmarked against Euro VI prices as against the present practice of the cost-plus model, Singh concluded.

New Delhi, Jul 18: The Covid-19 lockdown-led reduction in air pollution levels across five Indian cities, including Delhi and Mumbai, may have prevented about 630 premature deaths, and saved USD 690 million in health costs in the country, according to a new study.

Scientists, including those from the University of Surrey in the UK, assessed the levels of harmful fine particulate matter (PM2.5) from vehicles and other sources in five Indian cities -- Delhi, Mumbai, Kolkata, Chennai and Hyderabad -- since the beginning of the lockdown period.

The study, published in the journal Sustainable Cities and Society, compared these lockdown PM2.5 figures from 25 March up until 11 May, with those from similar periods of the preceding five years, and found that the measure reduced pollution levels in all these places.

According to the scientists, during this period, the levels of these harmful air pollutants reduced by 10 per cent in Mumbai, and by up to 54 per cent in Delhi.

"The percentage reduction for the other cities ranged from 24 to 32 per cent, which was slightly smaller than the measured values for Delhi and Mumbai," the scientists noted in the study.

"While the reduction in PM2.5 pollution may not be surprising, the size of the reduction should make us all take notice of the impact we have been having on the planet," said Prashant Kumar, a co-author of the study from the University of Surrey.

The scientists said these reductions in PM2.5 were comparable to those reported in other cities across the world, such as in Austria's capital Vienna (60 per cent), and Shanghai (42 per cent) in China.

They also calculated the monetary value of the reduced mortality due to air pollution and found that the lowered levels of PM2.5 may have saved 630 people from premature death, and USD 690 million in health costs in India.

According to the researchers, the present lockdown situation offers observational opportunities regarding potential control systems and regulations for improved urban air quality.

They said an integrated approach might help in understanding the overall impacts of Covid-19 lockdown-style interventions and support the implementation of relevant policy frameworks.

"This is an opportunity for us all to discuss and debate what the 'new normal' should look like - particularly when it comes to the quality of the air we breathe," Kumar said.
