INTRODUCTION

Climate change has become one of the most pressing challenges of the 21st century, affecting ecosystems, economies, and human life. In India, its impact is increasingly visible through rising temperatures, extreme weather events, and environmental degradation. While climate change is often viewed as a scientific or policy issue, it also raises important constitutional questions.

The Indian judiciary has expanded the scope of the right to life under Article 21 to include environmental protection. This has led to the recognition that a clean and healthy environment is essential for human dignity. As climate change directly threatens this balance, it is now being understood as a matter of fundamental rights.

2. DEFINITION AND RELEVANT PROVISIONS

Climate change refers to long-term alterations in temperature, weather patterns, and environmental conditions, primarily caused by human activities such as greenhouse gas emissions and deforestation.

Although the Constitution of India does not explicitly mention climate change, several provisions form the basis for its recognition as a fundamental right.

2.1 Article 21 – Right to Life

The Constitution of India guarantees the right to life and personal liberty. The Supreme Court has interpreted this provision broadly to include the right to live in a clean and healthy environment.

Environmental degradation, including the effects of climate change, directly impacts:

• Air quality 

• Access to water 

• Public health 

• Livelihood 

Thus, climate change can be linked to violations of Article 21.

2.2 Directive Principles of State Policy

The Constitution also places a duty on the State to protect the environment.

• Article 48A directs the State to protect and improve the environment 

• Article 51A(g) imposes a duty on citizens to safeguard natural resources 

While these provisions are not enforceable in courts, they guide interpretation and strengthen environmental rights.

2.3 Judicial Expansion of Environmental Rights

Indian courts have played a key role in recognising environmental protection as part of fundamental rights. Through judicial interpretation, environmental concerns, including climate change, have been brought within the constitutional framework.

2.4 Climate Change and Intergenerational Equity

Climate change also raises concerns of intergenerational equity, which refers to the responsibility of the present generation to preserve the environment for future generations. The effects of climate change, such as rising temperatures, depletion of natural resources, and loss of biodiversity, will have long-term consequences that extend beyond the present.

Indian courts have recognised that the right to life under Article 21 is not limited to the present generation alone. It includes the duty to ensure that future generations can also enjoy a clean and healthy environment. This principle strengthens the argument that climate change is not merely an environmental issue but a constitutional concern involving rights across generations.

3. ILLUSTRATION 

Consider a coastal village in India where rising sea levels have started affecting homes and agricultural land. Due to frequent flooding and saltwater intrusion, residents lose access to clean drinking water and fertile soil.

As a result:

• Families are forced to migrate 

• Livelihoods are destroyed 

• Health conditions worsen 

In such a situation, the effects of climate change directly interfere with the residents’ ability to live with dignity. This can be seen as a violation of their fundamental rights under Article 21.  

In addition to coastal regions, similar impacts can be seen in other parts of India. For instance, farmers facing irregular rainfall patterns often experience crop failure, leading to financial distress and food insecurity. Urban areas are also affected through rising heat levels and air pollution, which impact public health. These examples show that climate change is not limited to a single region but affects multiple aspects of life, thereby reinforcing its connection with fundamental rights.

4. CASE LAW

4.1 Subhash Kumar v State of Bihar

The Supreme Court held that the right to life includes the right to enjoy pollution-free water and air. This case laid the foundation for recognising environmental protection as a part of fundamental rights.

Key takeaway:
A clean environment is essential for the enjoyment of life under Article 21.

4.2 M C Mehta v Union of India

In this landmark case, the Court introduced the principle of absolute liability and emphasised the importance of environmental safety.

Key takeaway:
Industries must ensure that their activities do not harm the environment or public health.

4.3 Vellore Citizens Welfare Forum v Union of India

The Court recognised the principles of sustainable development, precautionary principle, and polluter pays principle as part of Indian environmental law.

Key takeaway:
Development must not come at the cost of environmental destruction.

4.4 Indian Council for Enviro-Legal Action v Union of India

In this case, the Supreme Court emphasised the importance of enforcing environmental laws strictly and held industries accountable for environmental damage. The Court reinforced the principle that environmental protection is essential for safeguarding public health and welfare.

Key takeaway:
Environmental harm cannot be ignored, and strict liability must be imposed to ensure accountability.

Overall Significance

These cases demonstrate how the judiciary has gradually expanded the meaning of fundamental rights to include environmental protection, forming the basis for recognising climate change concerns within constitutional law.

5. PRACTICAL APPLICATION

The recognition of climate change as a fundamental right has significant implications in practice.

5.1 Public Interest Litigation (PIL)

Citizens and organisations can approach courts through PILs to address environmental harm and climate-related issues. Courts have actively intervened in matters such as pollution control, forest conservation, and industrial regulation. This has made environmental litigation more accessible and has allowed courts to address climate-related concerns proactively.

5.2 Government Responsibility

The State is required to:

• Formulate policies to reduce emissions 

• Protect natural resources 

• Promote sustainable development 

Failure to take adequate action can be challenged as a violation of constitutional rights.

5.3 Role of Courts

Courts in India play an active role in environmental governance. They:

• Monitor compliance with environmental laws 

• Issue directions to authorities 

• Balance development with environmental protection 

This judicial activism has helped strengthen environmental rights.

5.4 Challenges in Implementation

Despite legal recognition, several challenges remain:

• Lack of effective enforcement 

• Conflicts between development and environmental protection 

• Limited awareness among citizens 

Climate change cases also involve complex scientific and policy issues, making judicial intervention difficult at times.

5.5 Emerging Importance

As climate change impacts become more severe, courts are increasingly being approached to address:

• Air pollution 

• Water scarcity 

• Climate-induced displacement 

This reflects a growing trend of treating climate change as a constitutional issue rather than merely a policy concern.

5.6 Role of Environmental Policies

Apart from judicial intervention, environmental policies and regulatory frameworks play an important role in addressing climate change. The government has introduced various initiatives aimed at reducing emissions and promoting renewable energy. However, the effectiveness of these policies depends on proper implementation and monitoring.

5.7 Need for Public Awareness

Public awareness is essential in addressing climate change as a fundamental right. Citizens must be informed about the environmental impact of their actions and the importance of sustainable practices. Increased awareness can lead to better compliance with environmental norms and greater participation in climate-related initiatives.

5.8 Balancing Development and Environment

One of the biggest challenges in India is balancing economic development with environmental protection. Infrastructure projects, industrial growth, and urbanisation often come into conflict with environmental concerns. Courts are frequently required to strike a balance between these competing interests while ensuring that fundamental rights are not compromised.

Climate change also has a disproportionate impact on vulnerable communities, including coastal populations, farmers, and economically weaker sections. These groups often lack the resources to adapt to environmental changes, making them more exposed to risks such as displacement, loss of livelihood, and health issues. Recognising climate change as a fundamental right helps ensure that these vulnerable sections receive greater legal protection and policy attention.

6. CONCLUSION

Climate change is no longer only an environmental issue; it is a constitutional concern that directly affects fundamental rights. Through judicial interpretation, the right to life under Article 21 has been expanded to include the right to a clean and healthy environment.

Recognising climate change as a fundamental right strengthens accountability and ensures that both the State and citizens take responsibility for environmental protection. While challenges remain, this approach provides a strong legal foundation for addressing one of the most critical issues of our time.

As climate challenges continue to intensify, the role of constitutional law in shaping environmental governance will become increasingly important. At the same time, recognising climate change as a fundamental right also requires a coordinated approach involving the judiciary, legislature, and executive. Legal recognition alone is not sufficient unless it is supported by effective policies and public participation. In this context, recognising climate change within the framework of fundamental rights ensures stronger legal accountability and long-term environmental protection.
