Delhi Bans Non-BS VI Vehicles Amid Air Pollution Crisis
The Delhi government has banned non-BS VI private vehicles from entering the city to fight air pollution.
BS norms are rules that control how much pollution vehicles can make.
The latest rule, BS-VI, makes fuel cleaner and vehicles use special filters to reduce harmful gases.
Delhi has been using stricter rules than the rest of India for years.
A special group called CAQM helps monitor and improve air quality in Delhi and nearby areas.
This change is important because many cities in India are struggling with bad air quality, and vehicles are a big part of the problem.
Delhi has banned non-BS VI private vehicles registered outside the city to combat air pollution.
BS-VI norms, implemented nationwide in 2020, significantly reduce sulphur content in fuel and mandate advanced exhaust treatment systems.
Delhi has historically implemented stricter emission norms earlier than the rest of India due to persistent air pollution.
The Commission for Air Quality Management (CAQM) was established in 2021 to monitor and improve air quality in NCR and adjoining areas.
BS-VI fuel reduces sulphur content from 50 ppm to 10 ppm, an 80% reduction, leading to cleaner emissions.
