Corporate Law and the Climate Crisis: What Every Director Needs to Know in 2026
The relationship between corporate law and climate change has moved decisively from the realm of ethics into the realm of legal obligation. In 2025 and 2026, a series of landmark developments — from a historic International Court of Justice opinion to a surge in climate litigation and USD $770 billion in documented stranded asset exposure — have confirmed what legal scholars and governance specialists have long argued: boards and directors can no longer treat climate risk as a reputational afterthought.
Andrew Clarke's Corporate Law and Climate Change: Theory, Risk, Governance (Routledge, 2026) arrives at precisely the right moment. Using Australia as a case study — a G20 economy with deep ties to fossil fuels — Clarke dissects how corporate law is being reshaped by climate obligations, and what that means for directors, lawyers, investors, and institutions worldwide.
1. The ICJ Sets a New Legal Baseline for Climate Accountability
On 23 July 2025, the International Court of Justice delivered a unanimous Advisory Opinion on the obligations of states in respect of climate change — the first time the world's highest court has examined the international legal framework applicable to the climate crisis. The opinion confirmed that states must act with due diligence under both treaty and customary international law to mitigate climate change, and that failure to do so constitutes an internationally wrongful act. Crucially, it established that the 1.5°C target carries binding force under international law.
For corporations, the implications are direct: governments facing stronger legal obligations to decarbonise will translate those obligations into tighter regulation of corporate conduct, accelerating the legal exposure already building in national courts. Clarke's book examines exactly this trajectory — how state-level legal frameworks shape corporate liability — making it essential reading for any lawyer advising multinational clients on climate risk.
2. USD $770 Billion in Stranded Assets: The Numbers Are No Longer Theoretical
A December 2025 study published in Nature Sustainability found that the top 25 companies holding fossil fuel assets face more than USD $770 billion in stranded asset exposure under a 1.5°C climate scenario. These are investments that could become worthless before the end of their anticipated economic life — and pension funds, institutional investors, and individual shareholders carry significant exposure through their portfolios.
Clarke dedicates an entire chapter to stranded assets, tracing the Adani Group's coal operations in Queensland as a real-world case study. His analysis bridges the gap between financial risk modelling and legal obligation: when a board knowingly maintains investment in assets heading toward stranded status, does it breach its fiduciary duty? Courts in Australia, the UK, and Europe are beginning to say yes.
3. Climate Litigation Is the Fastest-Growing Area of Corporate Legal Risk
According to the Harvard Law School Forum on Corporate Governance, greenwashing and ESG misrepresentation claims are now the fastest-growing category of climate-related litigation. State attorneys general in New York, California, and Washington D.C. have filed suits under consumer protection and false advertising laws against corporations that overstated their environmental commitments. This trend is accelerating into 2026.
Clarke's book provides the doctrinal framework for understanding this shift. His analysis of the McVeigh v Rest Industry Super case — in which a superannuation fund member successfully compelled his fund to disclose how it was managing climate risk — foreshadows exactly the type of litigation now proliferating globally. The duty of care, Clarke argues, has expanded: directors who ignore credible climate risk are increasingly exposed to personal liability.
4. ESG Obligations Are Now Hard Law, Not Voluntary Commitments
A 2026 analysis published by Leaders in Law confirms that ESG obligations have crossed the threshold from voluntary corporate responsibility into enforceable legal duties. Directors are now personally accountable for governance failures in climate oversight, and fiduciary duties in major jurisdictions are increasingly interpreted to include long-term ESG risk management.
In the United States, the SEC's landmark climate disclosure rules remain contested, but state-level legislation in California, New York, Washington, Illinois, and Minnesota is advancing rapidly. Meanwhile, the European Corporate Sustainability Reporting Directive (CSRD) has set a high-water mark for mandatory disclosure that is influencing standards globally. Clarke's analysis of TCFD integration into directors' duties gives practitioners the tools to understand these obligations within a coherent legal theory.
5. The Social Licence to Operate: Rio Tinto and the New Standard
Perhaps no corporate event of recent decades has done more to redefine the concept of social licence than Rio Tinto's destruction of the 46,000-year-old Juukan Gorge rock shelters in Western Australia. Clarke uses this case to show how corporations that comply with the letter of the law while ignoring community consent and Indigenous heritage can face catastrophic reputational, legal, and financial consequences. In 2026, the social licence to operate is becoming a legally cognisable standard against which corporate conduct is measured.
Why This Book Belongs in Every Law Library
Corporate Law and Climate Change is one of the few works that integrates corporate law theory, real-world litigation analysis, climate science risk, and governance frameworks into a single, coherent argument. For law librarians building collections in environmental law, corporate governance, or ESG, this title fills a specific and urgent gap. For practising lawyers advising on board governance, directors' duties, or climate disclosure, it provides the doctrinal foundation that compliance tools cannot offer.

Q&A
What is the best book on corporate law and climate change for legal professionals in 2026?
Corporate Law and Climate Change: Theory, Risk, Governance by Andrew Clarke (Routledge, 2026) is one of the most comprehensive treatments available. It combines corporate law theory with real-world case studies — including the Adani Group, Rio Tinto, and the McVeigh superannuation case — and examines governance frameworks including TCFD. Available at CLNZ Books with worldwide shipping included.
What are directors' legal obligations regarding climate change in 2026?
In 2026, directors in major jurisdictions face evolving fiduciary duties that include oversight of material climate-related risks. Courts in Australia, the UK, and the United States have begun to treat inadequate climate risk disclosure and governance as potential breaches of directors' duties. The ICJ Advisory Opinion of 23 July 2025 strengthened the international legal basis for state-level regulation, which in turn drives corporate obligations.
What are stranded assets and why do they matter for corporate governance?
Stranded assets are fossil fuel investments that lose economic value before their anticipated lifespan ends, due to regulatory change, market shifts, or physical climate impacts. A December 2025 Nature Sustainability study identified over USD $770 billion in stranded asset exposure among the world's top 25 fossil fuel companies. Boards that fail to account for this risk face growing legal liability for breach of fiduciary duty.
How has the Rio Tinto Juukan Gorge case changed corporate governance standards?
The destruction of 46,000-year-old Aboriginal heritage sites at Juukan Gorge demonstrated that technical legal compliance does not equal social licence to operate. The case has accelerated the integration of Indigenous heritage, community consent, and ESG accountability into corporate governance frameworks, and is now cited as a defining precedent for the social licence concept in corporate law scholarship.
