Background:
- The Taj Mahal, a UNESCO World Heritage Site, lies within the Taj Trapezium Zone (TTZ), a region notified for strict environmental protection to safeguard the monument from air pollution.
- Concerns about pollution from glass manufacturing units possibly affecting the air quality around the Taj Mahal were raised.
Key Directions by the Supreme Court:
- The Court instructed:
- NEERI to carry out a comprehensive assessment of pollution caused by these industries.
- NEERI must submit an affidavit indicating the time frame required for the study.
- The Uttar Pradesh Pollution Control Board (UPPCB) was asked to:
- Form a special inspection team.
- Submit an interim report on pollutants generated by the listed industrial units.
- The Court directed the government and concerned agencies to fully cooperate with NEERI during the investigation.
- The Bench also stated it would not hesitate to order the removal or relocation of the industrial units if NEERI’s findings confirm significant environmental damage.
- It emphasized that an in-depth scientific examination is essential to determine the extent of air pollution near the monument.
Why It Matters?
- The Taj Mahal’s white marble is highly sensitive to air pollutants, especially sulphur dioxide, nitrogen oxides, and particulate matter, which cause yellowing and surface corrosion.
- Glass industries may release harmful emissions if not properly regulated.
- The judgment reflects the judiciary’s proactive role in heritage conservation and environmental governance.
Why in News?
- On April 22, 2025, the Supreme Court of India directed the National Environmental Engineering Research Institute (NEERI) to assess the environmental impact of glass industrial units operating near the Taj Mahal.
