Government launches BS-IV grade fuels

Government has formally launched Bharat Stage-IV (BS-IV) grade transportation fuel across the country to keep carbon emission in check. The launch came days after the Supreme Court banned sale and registration of BS-III vehicles from 1 April, 2017. 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. BS-IV fuels BS-IV fuels contain far less sulphur than BS-III fuel. Sulphur in fuel makes it dirtier and lowers the efficiency of catalytic converters, which control emissions.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. About Bharat stage emission standards BS emission standards are emission standards instituted by the Union Government to regulate output of air pollutants from i...
