The potential implications of a U.K. legal case on corporate directors and Environmental, Social and Governance (ESG) initiatives could be far-reaching.

ClientEarth initiated legal action against the administrators of Shell plc due to their lacking of relevant efforts in protecting against global warming.

On February 2023, ClientEarth, an environmental law charity, has filed a groundbreaking lawsuit against the board of directors of Shell plc, with the goal of forcing them to take significant action towards mitigating climate change. The lawsuit is based on a novel legal theory, that corporate directors have a duty to tackle climate change. Specifically, ClientEarth wants Shell to move away from fossil fuels and align itself with the Paris Accords' goal of reaching net zero emissions by 2050. This case has far-reaching implications for the business sector; a successful outcome could redefine how businesses operate and open the door to similar legal action around the world. As such, the outcome of this case is worth watching closely.

Today, corporate directors face an increasingly difficult dilemma in balancing the need to protect their company’s long-term profits and the need to mitigate climate change. This debate is part of the broader Environmental, Social, and Governance (ESG) discussion. Experts are urging corporate directors to make the difficult decision of sacrificing short-term profits in order to ensure their company’s long-term success. This decision may not be easy, but it is necessary for companies to survive and thrive in the long run.

In 2019, ESG (environmental, social, and corporate governance) as a legal theory began to take shape, with the help of two United Nations affiliated organizations: The UN Environment Programme Finance Initiative (UNEP FI) and the Principles of Responsible Investment (PRI). The two organizations released a 2015 report titled “Fiduciary Duty in the 21st Century”, which asserts that ESG should be taken into account by directors and fund managers in certain jurisdictions. With this document, ESG became more than just an idea, it became reality.

In 2019, the organizations released an updated report that marked a major shift in the way they perceived ESG (environmental, social and governance) criteria in fiduciary duty. This report proposed that rather than considering ESG to be optional, it must be considered when making financial decisions as climate change poses a long-term threat to profits. This new approach has now been put to the test for the first time in a landmark case. The outcome of this case could have major implications for the way businesses approach ESG considerations going forward.

A unique legal case is being heard in the High Court of England and Wales that could have a ripple effect across the world. If the case is successful, it could result in similar lawsuits making their way through the U.S. legal system. The potential implications of this case have been seen in recent actions by the Securities and Exchange Commission, the Department of Labor's ERISA rule, Congress' response, and pending state actions. If the theory in question becomes mainstream, it could potentially circumvent these recent actions and lead to a new era of climate change litigation.
