Delhi Enforces New Vehicle Emission Norms

Summary of Key Points on Bharat Stage (BS) Emission Norms and Delhi's Pollution Control Measures

1. Bharat Stage (BS) Emission Norms:

   • India's standards regulating pollution from motor vehicles, establishing limits on exhaust emissions of CO, hydrocarbons, nitrogen oxides, and particulate matter.
   • Each successive BS standard introduces stricter emission limits, pushing manufacturers towards cleaner technologies and fuels.
   • BS I to BS-IV were phased in ahead of the rest of India:
     • BS II in Delhi (2001), BS III (2005), BS IV (2010), BS VI implemented in Delhi-NCR (April 2020) before nationwide rollout.

2. Current Measures in Delhi:

   • Non-BS VI vehicles registered outside Delhi are barred from entering the city.
   • Fuel sales are restricted to vehicles with a valid Pollution Under Control Certificate (PUCC).
   • Fines imposed: Rs 20,000 for non-BS VI vehicles entering Delhi, Rs 10,000 for BS VI compliant vehicles without a PUCC.

3. Vehicle Compliance Guidelines:

   • Vehicle owners can verify BS compliance through:
     • Registration Certificate (RC), usually indicating compliance standards.
     • VAHAN portal managed by the Ministry of Road Transport & Highways using the vehicle's license plate.
   • Vehicles registered post-April 2020 are generally BS VI compliant; pre-2020 vehicles may fall under BS IV (2010-2014), BS III (2005-2010), and BS II (2001-2005).

4. Pollution Impact of Older Vehicles:

   • Older vehicles (pre-BS IV) lack modern exhaust cleaning systems, leading to higher emissions.
   • BS VI vehicles use advanced technologies like diesel particulate filters (DPFs) and selective catalytic reduction (SCR) units, reducing particulates by over 90%.
   • Studies show emissions from older cars rise significantly with age due to deteriorating components.

5. Statistics:

   • Approximately 44 lakh end-of-life vehicles are estimated in NCR, with a higher concentration (62 lakh) in Delhi.
   • 37% of vehicles in Delhi-NCR are still under outdated BS I to BS III norms.

6. Environmental Significance of BS VI:

   • BS VI limits for petrol vehicles reduce nitrogen oxides by about 25% from BS IV; for diesel vehicles, reductions are nearly 68% in NOx and approximately 82% in particulate matter.
   • BS VI standards promote cleaner fuel with lower sulphur content and a more realistic testing regime.

7. Judicial and Policy Background:

   • Measures align with legislative efforts to combat air pollution and environmental degradation, reflecting the central government's commitment under the Constitution to uphold a healthy environment under Article 21 (Right to Life).

8. Commitments and Agreements:

   • The enforcement of stringent emission norms is part of broader commitments to improve urban air quality amidst international environmental agreements and initiatives.

By implementing these measures, the Delhi government aims to mitigate air pollution, safeguard public health, and transition towards a more sustainable transportation framework in line with global environmental standards.
