Decoding air pollution concerns in Delhi-NCR

Why in the News?

Delhi-NCR continues to experience severe air pollution, with vehicular emissions being the primary contributor to PM2.5 and toxic gases. Yet, public discourse and even judicial opinion often blame stubble-burning farmers in neighbouring States for worsening air quality. This has renewed debate on the Polluter Pays Principle (PPP) and its applicability to complex, transboundary pollution.

Background

• Polluter Pays Principle (PPP): Polluters should bear the cost of environmental damage.
• Recognised in Vellore Citizens Welfare Forum vs Union of India (1996) as part of Indian law.
• Incorporated in the National Green Tribunal Act, 2010.
• However, air pollution involves multiple point and non-point sources, and pollution often crosses administrative or national borders, making liability attribution difficult.
  
• Courts in India have largely used PPP to award compensation and environmental restoration, aligning it more with corrective justice than strict liability-based cost internalisation.

Features

Proportional Liability Matters

• The Standley case (ECJ, 1999) added proportionality to PPP.
• Farmers cannot be solely blamed for pollutants also caused by urban-industrial activities.

Air Pollution is transboundary

• Influenced by regional and global atmospheric circulation.
• The landmark Trail Smelter case (1941) recognised cross-border liability.
• International treaties like:
  • CLRTAP (1979)
  • ASEAN Haze Agreement (2002)
• PM2.5 was recognised as a long-range pollutant in the 2012 Gothenburg Protocol amendment.

Shift Towards “Government-Pays Principle”

• Judiciary focuses on government-led monitoring and mitigation.
• Victims rarely litigate individually.
• Emphasis on welfare-maximising intervention, not full cost internalisation.

Weak Institutional Enforcement

• Authorities under environmental laws exist, but face administrative lapses.
• Courts increasingly intervene.

Challenges

• Attribution complexity: Multiple sources → difficult to assign liability fairly.
• Judicial ambiguity: No clear valuation method for environmental damage.
• Implementation Gaps: Regulatory authorities lack capacity and coordination.
• Trans-boundary dimension ignored: Policy remains largely city-centric.
• PPP diluted: Government bears the clean-up burden instead of the polluters.
• Citizens’ environmental duties are under-discussed.

Way Forward

• Develop scientifically credible apportionment frameworks for pollution responsibility.
• Strengthen institutional capacity and independent monitoring.
• Enhance regional cooperation for cross-border air quality management.
• Re-align PPP so that:
  • Polluters (industrial, vehicular, construction, waste burning) internalise costs.
• Public awareness of shared environmental duties.
• Judicial policy clarity on damage valuation and liability principles.

Conclusion

Air pollution in Delhi-NCR is a multi-source, trans-boundary phenomenon, not reducible to a single cause such as stubble burning. While Indian courts formally uphold the Polluter Pays Principle, in practice the burden has shifted to the State, creating a “government-pays principle”. A more balanced regime is needed, combining proportional liability, institutional reform, and regional cooperation to ensure genuine cost internalisation and public health protection.
