Financial Institutions Facing Trial: The Potential Impact of Climate Lawsuits on Banking Systems, Spurring Systemic Transformation

In a significant development, climate advocates are pushing for financial institutions to align with the global fight against climate change. The logic is simple: if fossil fuel companies are expected to reduce their emissions, then those bankrolling them should also take similar steps.

This push is not just resonating within the banking sector. Its ripples are accelerating climate alignment across sectors, particularly in carbon-intensive industries such as energy, transportation, and heavy manufacturing.

Recent cases, such as the one against BNP Paribas in France, allege that the bank's continued support for fossil fuel expansion violates its obligation to prevent human rights and environmental harms linked to its business activities. Similarly, a Dutch court of appeal has already ordered Shell to reduce its emissions, affirming that companies can be held legally accountable for their contribution to global warming.

These legal battles come with consequences for banks. They face increased litigation risk, regulatory scrutiny, and reputational damage. The advisory opinion suggests that the climate due diligence and duty of care of banks may come under increased scrutiny in climate litigation. Successful litigation could influence financial regulators and central banks, leading to tougher oversight of climate risks in the financial system.

Two such cases are currently making their way through European courts: one against ING in the Netherlands and one against BNP Paribas in France. The organizational entity behind the lawsuit against ING, Milieudefensie, is leading the charge.

These lawsuits rest on an evolving legal foundation, using national tort laws, corporate responsibility statutes, and human rights frameworks to argue that banks have a duty of care towards their clients, society, and the environment. The International Court of Justice has issued an advisory opinion that confirms climate change leads to infringements of human rights and that the law has a role in addressing these issues.

If successful, these cases could shift the ground rules of global investment and place the financial sector squarely in the frame of climate accountability. High-carbon projects heavily rely on external funding and financial services. If banks are held legally responsible for the emissions they finance, companies will face stronger demands for emissions transparency and climate transition plans.

ESG frameworks and sustainability reporting by banks are predominantly voluntary and do not always include binding phase-out plans. Litigation could force banks to clarify their climate targets and impose judicially enforced timelines for reaching them.

The ING case in the Netherlands argues that the bank's climate policy fails to comply with international climate agreements and that it is not doing enough to reduce financed emissions. If courts uphold the claims, a legal duty for banks to prevent and phase-out high-carbon investments will be created.

Climate litigation against financial institutions is growing, with cases challenging their role in the climate crisis or lack of action in addressing it. The outcomes of these cases will determine how climate risks are recognised as a financial liability and whether financial institutions will be legally required to phase out high-emission investments.

The scientific urgency to reduce greenhouse gas emissions is high, and every year of delay makes it more difficult and costly to avoid irreversible damage. As the legal landscape evolves, it remains to be seen how financial institutions will respond and whether they will play a more proactive role in the fight against climate change.
