Bharat Stage-IV has been formally launched by the government across the country to keep carbon emission in check. Post the banning of sale and registration of BS-III vehicales by the Supreme Court this was launched. It sets target of ushering in BS-VI fuel by April 2020 by skipping BS-V fuel. All state-run oil marketing companies will provide BS-IV-compliant fuel at their 53, 500 retail fuel stations across the country.

What are Bharat Stage Emissions?

  • They are emission standards which are instituted by the Government of India
  • They are made to regulate the output of air pollutants from internal combustion engines and spark ignition engines
  • The standards and the timeline for implementation are set up the Central Pollution Control Board under the Ministry of Environment & Forests and climate change.
  • These standards were 1st introduced in 2000.
  • All the new vehicles have to be installed with this norms
  • Since October 2010, Bharat Stage (BS) III norms have been enforced across the country.
  • In 13 major cities, Bharat Stage IV emission norms have been in place since April 2010and It’s enforced for whole country from April 2017.
  • In 2016, the Indian government announced that the country would skip the BS-V norms altogether and adopt BS-VI norms by 2020.
  • The introduction and phasing out of 2 –stroke engine for two wheelers were done by these standards
  • They bring down pollution levels and increased vehicle cost due to improved technology & higher fuel prices.
  • Due to this the health is also improved and there is lesser amount of particulate matter and pollution in the air.
  • Exposure to air pollution can lead to respiratory and cardiovascular diseases, which is estimated to be the cause for 6.2 lakh early deaths in 2010, and the health cost of air pollution in India has been assessed at 3 % of its GDP.

About BS-IV fuels: -

  • BS-IV contain far less sulphur than BS-III fuel
  • Sulphur makes the fuel dirtier and it lowers the efficiency if catalytic converters
  • The BS-IV complaint vehicles release less pollutants Carbon Mono-oxide (CO), Hydrocarbon (HC), Oxides of Nitrogen (NOx), Sulphur (SOx) and particulate matter (PM) compared to BS III complaint vehicles.
