Climate change litigation

Climate change litigation represents a significant evolution in environmental law, leveraging the judicial system to compel action where political processes have faltered. As global efforts to mitigate greenhouse gas emissions face political inertia, activists, NGOs, and increasingly, affected communities, are turning to courts. This strategy aims to establish legal precedents that push public institutions and private corporations towards more ambitious climate goals.

It involves a diverse array of legal claims, including constitutional challenges based on rights to a healthy environment, administrative law appeals against inadequate environmental policies, private law actions for negligence or nuisance, and consumer protection suits concerning greenwashing or fraud. The rise of climate litigation signifies a critical shift, recognizing that legal recourse can be a powerful, albeit complex, tool in addressing the existential threat of climate change.

While environmental law has a long history, climate change litigation as a distinct field began gaining momentum in the early 2000s. Initially, cases were few and far between, often focusing on specific emissions or policy challenges. However, the increasing scientific consensus on anthropogenic climate change and the visible impacts of global warming spurred a dramatic increase in legal activity.

The UN's 2017 Litigation Report identified 884 cases globally; by December 2022, this number had surged to over 2,180, with a significant portion filed in the United States but a growing number across Europe, Asia, and other regions. This exponential growth reflects a maturing legal strategy, supported by developing legal frameworks and a greater understanding of climate science among legal professionals and the judiciary.

The importance of climate litigation extends far beyond individual court victories. It serves as a vital mechanism for enforcing climate commitments and holding powerful entities accountable for their contributions to the climate crisis. Successful cases can lead to concrete policy changes, such as mandated emissions reductions or the cancellation of fossil fuel projects.

Furthermore, climate litigation is increasingly intertwined with the principles of climate justice, often amplifying the voices of vulnerable communities disproportionately affected by climate impacts. By framing climate inaction as a violation of fundamental human rights, such as the right to life, health, and a stable environment, litigants are challenging the moral and legal adequacy of current responses, pushing for a more equitable and sustainable future.

Climate litigation operates through several distinct legal pathways. Constitutional litigation asserts that governments have failed to uphold their duty to protect citizens from climate harm, often citing rights to life, liberty, and property. Administrative litigation challenges the legality and rationality of government decisions related to environmental permits, energy policies, or climate plans.

Private law claims, such as negligence or nuisance, target corporations for damages caused by their fossil fuel activities or for failing to adapt to foreseeable climate risks. Fraud and consumer protection claims address misleading statements about environmental performance or product impacts. A particularly impactful trend since 2015 has been the increased use of human rights arguments, bolstered by the growing recognition of the right to a healthy environment in various jurisdictions and international forums.

The landscape of climate litigation is marked by several high-profile cases. Urgenda Foundation v. The Netherlands (2019) famously compelled the Dutch government to increase its emissions reduction targets.

In Germany, the Neubauer v. Germany case (2021) led to stronger climate protection laws after a constitutional court ruled existing measures insufficient for future generations. Milieudefensie v.

Royal Dutch Shell (2021) was a landmark ruling against a corporation, ordering Shell to cut its emissions significantly. While cases like Juliana v. United States have faced significant hurdles, they highlight the determination of young people to secure a livable future.

Emerging trends include cases targeting financial institutions for funding fossil fuels and increasing international cooperation where decisions in one jurisdiction can influence others, though counter-litigation challenging climate action also exists.
