Air Pollution

On the right to a healthy environment

Why in the News

Severe winter smog in Delhi-NCR, repeated resort to emergency measures such as work-from-home and school closures, and judicial monitoring of pollution control have once again exposed the limits of India’s environmental governance framework. Despite decades of environmental legislation and court-led expansion of Article 21, air pollution continues to cause large-scale morbidity and mortality through diseases such as stroke, heart ailments, and lung disorders. 

Introduction

Environmental protection in India was not originally embedded as an enforceable constitutional right. However, through judicial interpretation, particularly under Article 21, the Supreme Court has progressively recognised a healthy environment as integral to the right to life.

How serious is India’s air pollution crisis?

  1. Urban air quality: Causes chronic exposure to particulate matter, especially PM2.5, leading to cardiovascular and respiratory diseases.
  2. Particulate matter dominance: PM2.5 identified as the most hazardous pollutant due to deep lung penetration and long-term health impact.
  3. Children’s vulnerability: Sub-category ultrafine particles disproportionately affect children.
  4. Policy response: Commission for Air Quality Management (CAQM) mandated closures and activity restrictions under different GRAP phases.
  5. Governance gap: Emergency responses substitute for long-term structural correction.

What are the major sources of environmental degradation discussed?

  1. Fossil fuel combustion: Transport and industrial emissions identified as primary contributors.
  2. Industrial processes: Release of harmful particulates and toxic waste.
  3. Waste management failures: Open burning and improper disposal.
  4. Construction and demolition: Dust generation contributing to PM load.
  5. Agricultural practices: Crop residue burning aggravating seasonal pollution.

How has the Constitution been interpreted to protect the environment?

  1. Judicial interpretation: Environment read into Article 21 through purposive interpretation.
  2. Key precedent: Maneka Gandhi v. Union of India (1978) expanded the meaning of life and personal liberty.
  3. Explicit linkage: Subhash Kumar v. State of Bihar (1991) recognised the right to pollution-free water and air as part of Article 21.
  4. Directive Principles: Articles 48A and 51A(g) impose duties on the State and citizens.
  5. Limitation: Absence of an explicit Fundamental Right creates enforcement ambiguity.

What environmental protection principles guide Indian jurisprudence?

  1. Strict liability: Accountability for environmental harm irrespective of intent.
  2. Precautionary principle: Preventive action justified even in absence of scientific certainty.
  3. Polluter pays principle: Costs of pollution borne by the polluter, including prevention and remediation.
  4. Sustainable development: Rejection of development-ecology trade-off.
  5. Judicial endorsement: Principles recognised in Vellore Citizens’ Welfare Forum v. Union of India (1996).

What is the public trust doctrine and why is it important?

  1. State as trustee: Natural resources held by the State for public benefit.
  2. Ownership structure: Citizens are beneficiaries, not owners.
  3. Judicial recognition: M.C. Mehta v. Kamal Nath affirmed State’s fiduciary duty.
  4. Governance implication: Restricts arbitrary commercial exploitation.
  5. Constitutional basis: Draws support from Directive Principles.

Why is current protection considered inadequate?

  1. Reactive governance: Reliance on emergency measures rather than prevention.
  2. Judicial overreach risk: Courts stepping into regulatory roles due to executive inaction.
  3. Weak enforcement: Persistent pollution despite decades of litigation.
  4. Policy fragmentation: Overlapping authorities with limited coordination.
  5. Constitutional silence: Lack of explicit environmental right reduces accountability.

Should the right to a healthy environment be explicitly constitutionalised?

  1. Clarity of obligation: Defines enforceable State responsibility
  2. Justiciability: Strengthens citizen access to remedies.
  3. Governance discipline: Limits ad-hoc executive responses.
  4. Comparative practice: Many constitutions explicitly recognise environmental rights.
  5. Democratic accountability: Aligns rights with duties of the State.

Conclusion

The judicial recognition of a clean and healthy environment as an integral part of the right to life reflects the constitutional dynamism of Indian environmental jurisprudence. However, persistent pollution, reliance on emergency measures, and weak enforcement mechanisms reveal the limits of court-led constitutionalisation, underscoring the need for explicit constitutional recognition and stronger executive accountability to translate environmental rights into lived realities.

PYQ Relevance

[UPSC 2022] The most significant achievement of modern law in India is the constitutionalisation of environmental problems by the Supreme Court.” Discuss with relevant case laws.

Linkage: This question is directly relevant to GS Paper II as it examines the judicial expansion of Article 21 to include the right to a clean and healthy environment through constitutional interpretation.
