Bharat stage norms bs

               BHARAT STAGE NORMS (BS)

Introduced in the year 2000, the Bharat norms are emission control standards put in place by the government to keep a check on air pollution. Based on the European regulations (Euro norms), these standards set specifications/limits for the release of air pollutants from equipment using internal combustion engines, including vehicles. Typically, the higher the stage, the more stringent the norms.

The BS IV norms were introduced in 13 cities apart from the National Capital Region from April 2010. Currently, BS IV fuel is being made available across the country in stages, with the entire nation expected to be covered by April 1 2017.

Implementation of the BS V standard was earlier scheduled for 2019. This has now been skipped. BS VI, originally proposed to come in by 2024 has been now advanced to 2020, instead.

While BS IV-compliant fuel currently in use has 50 parts per million (ppm) sulphur, BS VI stipulates a low 10 ppm.

The Archaeological Survey of India (ASI) and Central Pollution Control Board (CPCB) are continuously monitoring ambient air quality in 254 cities / towns in the country including vulnerable monuments.
