Bharat Stage Norms
Why in News?
🔰 Delhi became the first city in India to supply ultra-clean Bharat Stage (BS) VI grade fuel
(both petrol and diesel) with an aim to combat the rising levels of air pollution in DelhiNCR
region.
What is it?
🔰Bharat stage emission standards (BSES) are emission standards instituted by the
Government of India to regulate the output of air pollutants from internal combustion
engines and Spark-ignition engines equipment, including motor vehicles.
🔰The standards and the timeline for implementation are set by the Central Pollution Control Board under the Ministry of Environment & Forests and climate change.
🔰 The standards, based on European regulations were first introduced in 2000.
🔰In 2016, the Indian government announced that the country would skip the BS-V norms altogether and adopt BS-VI norms by 2020.
How BS VI is different?
🔰The major difference in standards between the existing BS-IV and new BS-VI auto fuel
norms is presence of sulphur.
🔰BS-IV fuels contain 50 parts per million (ppm) sulphur, while BS-V and BS-VI grade fuel
will have 10 ppm sulphur.
🔰 It will also bring down the emission of NOx (nitrogen oxides) from diesel cars by nearly
70% and 25% from cars with petrol engines.
🔰It will also bring down cancer causing particulate matter emissions from diesel engine cars
by phenomenal 80%.
