Bureau of Indian Standards (BIS), India's specifications and standards regulatory body, announced it has revised the standards on petrol and diesel as per Bharat Stage (BS) VI fuel norms from the earlier BS IV emission norms.

"BIS has revised the Indian Standards on Petrol (IS 2796) and Diesel (IS 1460) as per BS VI fuel norms. So far, these standards covered fuel requirements based on emission norms up to BS IV," BIS said in a statement. 

BS norms introduced in 2000 are emission control standards introduced by the government, based on European emission standards, to keep a check and control over release of air pollutants from equipment using internal combustion engines including vehicles.

The amount of Sulphur in both petrol and diesel in BS-VI fuel is limited to a maximum of 10 parts per million (PPM), similar to that of its Euro counterpart. Oil retailers introduced the BS-IV grade auto fuel across the country in April 2017 and planned to leapfrog to BS-VI grade fuel by April 2020. The companies have already invested around Rs 30,000 crore in order to upgrade their facilities to adhere to the grade change.

Stubble burning by farmers in Punjab and Haryana -- coupled with vehicular pollution, construction activities and low temperature - had turned the country's national capital and the adjoining regions in a gas chamber last year in November.

The level of particulate matter PM2.5 in the air peaked at 743 microgram per meter cube in November last year forcing authorities to shut schools and doctors to declare to declare a public health emergency.

In response to the deteriorating air quality in the national capital, Oil Minister Dharmendra Pradhan in November 2017 announced the government's plan to advance the introduction of cleaner auto grade fuel Bharat Stage VI or BS VI in Delhi and National Capital region.

"With a view to conserve natural resources as well as to reduce pollution, Government has decided to implement BS VI emission norms in Delhi NCR from 1 April 2018. In rest of the country these will be implemented from 1 April 2020," BIS said in its release.

The BIS statement also said the revised standards will improve the environment and reduce respiratory problems due to reduction in permissible Sulphur content which will also reduce emission of nitrogen oxides (NOX). Also, these standards permit increased blending of Ethanol in petrol and bio-diesel in diesel which will help in conservation of natural resources and reduction in import of Crude.
