As the impacts of climate change intensify, the role of courts in addressing environmental issues has become increasingly critical. Around the world, climate change litigation has emerged as a powerful tool for holding governments and corporations accountable for environmental harm. Courts are now at the forefront of shaping environmental policy, enforcing existing laws, and ensuring that international commitments to combat climate change are upheld. In this blog, we will explore the growing influence of climate litigation, highlight key cases globally and in India, and discuss how judicial actions are pushing the agenda for climate accountability and reform.

The Rise of Climate Change Litigation

Climate change litigation has grown exponentially over the past decade as activists, communities, and civil society organizations have turned to the courts to compel governments and businesses to take stronger action on climate change. These lawsuits are typically aimed at either forcing regulatory bodies to comply with climate commitments or holding corporations accountable for their role in exacerbating the climate crisis.

Key Drivers of Climate Litigation:

• Failure to Meet Climate Commitments: Governments are being sued for failing to meet their commitments under international treaties such as the Paris Agreement or for neglecting to enforce national environmental laws.
• Corporate Accountability: Large corporations, especially those in the fossil fuel industry, are being targeted for their significant contributions to greenhouse gas emissions and environmental damage.
• Human Rights Violations: Increasingly, climate cases are being framed as violations of fundamental human rights, such as the right to life, health, and a healthy environment, as climate impacts disproportionately affect vulnerable populations.

Key Climate Change Litigation Cases Globally

Several landmark cases globally have set important precedents for climate change litigation and environmental law enforcement:

1. Urgenda Foundation v. The Netherlands (2015):

• Significance: This case marked a watershed moment in climate litigation. The Dutch Supreme Court upheld a lower court’s ruling that the Dutch government had a legal duty to reduce greenhouse gas emissions by at least 25% by 2020, based on its obligations to protect human rights and public health.
• Impact: The Urgenda case is often cited as a landmark in holding governments accountable for their failure to address climate change and for setting a judicial precedent for climate action based on human rights.

2. Juliana v. United States (2015):

• Significance: Filed by a group of young plaintiffs, this case argued that the U.S. government’s failure to take adequate action on climate change violated their constitutional rights to life, liberty, and property.
• Impact: Although the case was ultimately dismissed in 2020 on procedural grounds, it has raised important questions about the role of the judiciary in climate policy and the responsibility of governments to future generations.

3. Milieudefensie et al. v. Royal Dutch Shell (2021):

• Significance: In a groundbreaking decision, a Dutch court ordered Royal Dutch Shell to reduce its global carbon emissions by 45% by 2030 compared to 2019 levels. The ruling was based on the argument that Shell’s business activities violated its duty of care under Dutch law and contributed to climate change.
• Impact: This case set a precedent for corporate accountability, showing that multinational corporations can be legally obligated to align their business practices with climate goals.

Climate Change Litigation in India

India, with its large population and vulnerability to climate impacts, has seen its share of climate litigation, often rooted in the interpretation of constitutional rights, environmental laws, and international obligations.

1. MC Mehta v. Union of India (1986):

• Significance: Although not directly a climate change case, this landmark ruling laid the foundation for India’s robust environmental jurisprudence. The case resulted in the closure of polluting industries near the Taj Mahal and highlighted the judiciary’s willingness to protect the environment.
• Impact: This case demonstrated that the Indian courts could play an active role in enforcing environmental laws and principles like the Polluter Pays Principle and Precautionary Principle, which have become central to climate litigation.

2. Ridhima Pandey v. Union of India (2017):

• Significance: Filed by a 9-year-old girl, this case challenged the Indian government’s failure to adequately address climate change, citing violations of the Paris Agreement and the fundamental right to a healthy environment under Article 21 of the Indian Constitution.
• Impact: Although dismissed, the case brought attention to the link between climate action and constitutional rights in India, setting the stage for future litigation that could compel stronger climate policies.

3. The Ganga and Yamuna Rivers Case (2017):

• Significance: In this case, the Uttarakhand High Court declared the rivers Ganga and Yamuna as legal entities, granting them the same rights as human beings. While not specifically focused on climate change, the ruling underscored the judiciary’s role in protecting natural resources through innovative legal reasoning.
• Impact: The case has opened doors for using the rights of nature as a legal tool in environmental protection, which could be applied in climate-related lawsuits.

Courts Interpreting Environmental Laws and International Treaties

Courts worldwide are increasingly interpreting environmental laws and international treaties through the lens of climate change. National courts are looking to international frameworks like the Paris Agreement, Kyoto Protocol, and the United Nations Framework Convention on Climate Change (UNFCCC) to hold governments and corporations accountable.

International Climate Agreements in Litigation:

• Courts are using international climate agreements as benchmarks to evaluate whether governments and corporations are doing enough to combat climate change. For example, in the Urgenda case, the Dutch court used the Paris Agreement to establish a baseline for acceptable emissions reductions.
• In India, while the judiciary has not yet directly applied international climate agreements, cases like Ridhima Pandey demonstrate the growing trend of using international commitments as a yardstick for evaluating national climate policies.

Enforcing Corporate Accountability for Environmental Damage

As the focus on corporate social responsibility grows, climate litigation increasingly targets large corporations for their environmental impact. Courts are playing a critical role in determining whether companies are responsible for contributing to climate change and holding them accountable for damages.

1. The Rise of the Polluter Pays Principle: The Polluter Pays Principle is gaining traction in climate litigation. This principle, which holds that the polluter should bear the costs of managing pollution, is frequently invoked in cases where corporations have been found responsible for excessive greenhouse gas emissions. Indian courts, such as in MC Mehta v. Kamal Nath (1997), have been pioneers in adopting this principle, and it is becoming increasingly relevant in climate-related cases globally.
2. Corporate Accountability Trends: Courts are now issuing rulings that force corporations to align their practices with climate goals, as seen in the Shell case. In India, as corporate sustainability reporting becomes mandatory, we can expect more litigation challenging companies that fail to reduce their environmental impact in accordance with the country’s Nationally Determined Contributions (NDCs) under the Paris Agreement.

The Impact of Litigation on Global Climate Change Policy

Climate litigation is playing an important role in shaping global climate change policy. Successful lawsuits have led to:

• Stronger Climate Commitments: Court rulings have pressured governments to strengthen their climate commitments, ensuring that they meet international targets for emissions reductions.
• Public Awareness: Climate lawsuits often garner significant public attention, raising awareness of environmental issues and pushing climate action higher up the political agenda.
• Policy Reform: In some cases, litigation has led to tangible policy reforms, such as improved regulations on carbon emissions, more stringent environmental assessments, and greater transparency in corporate reporting on environmental impact.

India’s Role in Global Climate Litigation Trends

India, as a developing nation, faces unique challenges in balancing climate action with economic growth. However, Indian courts have been proactive in promoting environmental protection, often interpreting the right to life (Article 21) to include the right to a healthy environment.

• Indian courts are increasingly willing to take bold stances on environmental issues, as seen in the MC Mehta series of cases, and future climate litigation in India is likely to focus on aligning national laws with international commitments like the Paris Agreement.
• India’s National Green Tribunal (NGT) has also become a key player in addressing environmental concerns, offering a specialized forum for environmental litigation that could be crucial in tackling climate-related cases.

Conclusion

Climate change litigation is shaping the future of environmental policy worldwide. As courts hold governments and corporations accountable for their environmental responsibilities, the judicial system is emerging as a powerful force in driving climate action. With key rulings establishing new precedents for corporate and government liability, and the growing trend of using human rights frameworks in climate cases, the role of the judiciary will only become more crucial in the global fight against climate change.

India, with its vast environmental challenges and proactive judiciary, is well-positioned to be a leader in climate litigation, setting legal standards that could influence global climate policies. The intersection of law, environmental protection, and climate justice will continue to evolve, with litigation playing a vital role in shaping a sustainable future.
