Bharat Stage Norms Current Affairs

Mercedes-Benz first to launch locally-made BS-VI-compliant car

German auto major Mercedes-Benz has unveiled India’s first BS-VI-compliant S Class car produced at its Pune facility. The BS-VI-compliant S Class car was unveiled more than two years ahead of Government’s deadline of April 2020 for switching to new BS-VI emission norms.

Key Facts

BS-VI-compliant S Class can run on BS-IV fuel, which will bring down NOx emissions by 68% and PM by 82%. This will lower the CO2 burden by 13% and fuel demand by 10%. This will pave way for other car manufacturers to introduce their vehicles which are compliant with new emission regulation

Bharat Stage Norms

Bharat stage (BS) emission standards are emission standards instituted by Central Government to regulate the output of air pollutants from internal combustion engine equipment, including motor vehicles. The standards and the timeline for implementation are set by Central Pollution Control Board (CPCB) under Ministry of Environment & Forests and climate change. These standards are based on European regulations were first introduced in 2000.

BS-VI

The Union Government in October 2016 had decided to skip one stage and migrate to BS-VI directly from BS-IV from April 2020 to fight the growing pollution. At present, all new vehicles being registered are BS- IV-emission compliant. By switching to BS-VI, India will join league of US, Japan and European Union, which follow Euro Stage VI emission norms.

Implications of BS-VI standard on environment

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 NOx emissions from diesel cars by 68% and 25% from petrol engine cars. Cancer causing particulate matter emissions from diesel engine cars will also come down by a phenomenal 80%.

Government to introduce BS-VI auto fuels in Delhi from 2018

The Petroleum Ministry in consultation with Public Oil Marketing Companies (OMCs) has decided for preponement of BS-VI grade auto fuels in National Capital Territory (NCT) of Delhi from 1st April 2018 instead of 1st April 2020.

This decision was taken into account the serious pollution levels in Delhi and adjoining areas and as part of government’s concerted efforts to reduce vehicular emissions and improve fuel efficiency with an aim to reduce the carbon footprints and keep a healthy environment.

Bharat Stage Norms

Bharat stage norms are emission standards instituted by Government to regulate output of air pollutants from internal combustion engine equipment, including motor vehicles. The standards and timeline for implementation are set by Central Pollution Control Board (CPCB) under Ministry of Environment & Forests and climate change.

The standards are based on European regulations and were first introduced in 2000. Since then, various stages Bharat Stage compatible fuel and ungraded and modified vehicles were introduced throughout the country.

The harmful emissions that are identified for regulations in different Bharat Stages (BS) are carbon monoxide (CO), unburnt hydrocarbons (HC), Nitrogen Oxides (NOx) and Particulate matter (PM). Each stage specifies a certain limit on the pollutants released, Higher the Bharat Stage goes lesser it emits pollutants. BS-I, BS-II and BS-III stages were launched in 2000, 2005 and 2010 respectively

BS VI Norms

The BS-IV compliant fuels have Sulphur concentration of 50 parts per million (ppm). It will come down to 10 ppm in BS-VI compliant fuels and auto engines. It will result in lower level of harmful emissions and reduced incidence of lung diseases. Moreover, switch to BS-VI norms will also reduce concentration of carbon monoxide (CO), unburnt hydrocarbons, nitrous oxide (NOx) and particulate matter from emissions.
