What are the Bharat Stage Emission Standards? How do they control emissions? And what’s our Auto fuel policy?
- Bharat stage emission standards (BSES) are emission standards instituted by the Government of India to regulate the output of air pollutants from compression ignition 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, Forest and Climate Change .
- Since the year 2000, India started adopting European emission and fuel regulations for four-wheeled light-duty and for heavy-duty vehicles. India’s own emission regulations still apply to two- and three-wheeled vehicles.

from above figure data 👇👇
- 1991– India introduced the emission norms for the first time.
- 1996– The norms saw some tightening as govt. asked most vehicle manufacturers to incorporate catalytic converters to cut exhaust emissions.
- Govt. also notified fuel specifications based on environmental considerations, which were to be implemented by 2000.
- 2000– Govt. notified BS-I and BS-II standards, which were equivalent to Euro I and Euro II respectively. <BS-II was for the NCR and BS-I for the rest of India>
- 2005– BS-III and BS-II fuel quality norms came to be implemented. <BS-III for 13 major cities and BS-II for the rest of India>
- 2010– BS-IV and BS-III fuel quality norms were introduced. <BS-IV for 13 major cities and BS-III for the rest of India>
It works on a two-pronged strategy to control the air pollutant output.
- Reducing the Sulphur content in the fuel.
- At engine level, it augments some equipment which reduces emissions.
- Govt. has decided to implement Bharat Standards VI norms April 1, 2020. This comes in the wake of pressure from Supreme Court to implement clean vehicular fuel norms soon amid concerns on rising air pollution especially in Delhi.
