The number of climate change cases filed worldwide has more than doubled in the past five years, crossing roughly 2,500 filings since 2017 according to databases maintained by the Sabin Center for Climate Change Law at Columbia Law School. The trend is reshaping how governments and corporations face climate accountability.

Why are climate cases flooding the courts?

Malaysian and international observers note a clear shift: climate advocates increasingly turn to judges rather than legislators. The Malay Mail captured the pivot in a recent headline: "Climate hopes shift from politics to the courts as legal battles heat up."

Several forces drive the surge:

• Slower legislative progress on emissions targets
• Rising compensation claims tied to climate-related disasters
• Stronger scientific attribution linking emissions to specific events
• Sympathetic rulings in senior national courts

The Grantham Research Institute at the London School of Economics has tracked similar acceleration in its annual Global Trends in Climate Change Litigation reports.

What landmark rulings have courts issued?

The International Court of Justice issued an advisory opinion on July 23, 2025 declaring that states have binding legal obligations under international law to limit greenhouse gas emissions and protect the climate system. The Hague-based court's 15-judge ruling answered questions put by the UN General Assembly in 2023.

In Strasbourg, the European Court of Human Rights held in KlimaSeniorinnen v. Switzerland (April 9, 2024, application no. 53600/20) that Switzerland had failed to adopt adequate measures to combat climate change, breaching Article 8 of the European Convention on Human Rights. The 17-judge Grand Chamber ruled 16-1.

Montana's Supreme Court ruled August 14, 2023 in Held v. State, No. DA 23-0575, that state agencies had unlawfully ignored greenhouse gas emissions when permitting fossil fuel projects. The court reversed a lower-court dismissal, giving the 16 youth plaintiffs a constitutional pathway to challenge state energy policy.

The Netherlands' Supreme Court on December 20, 2019 upheld the landmark Urgenda decision (case ECLI:NL:HR:2019:2006), requiring the government to cut greenhouse gas emissions by at least 25% by end of 2020 compared with 1990 levels.

Germany's Federal Constitutional Court ruled March 24, 2021 in Neubauer v. Germany, 1 BvR 2656/18, that a 2019 climate law insufficiently protected future generations. Legislators responded with strengthened 2030 emissions targets.

What does this mean for practitioners?

Litigators advising corporates, energy companies, and sovereign clients now treat climate claims as a core practice area rather than a niche specialty. Three shifts stand out.

First, liability theories now include shareholder-derivative suits, greenwashing investigations, and human-rights arguments in regional courts. Compliance teams should audit public emissions statements with the same rigor applied to financial disclosures.

Second, the ICJ advisory opinion, while non-binding, supplies litigants with a fresh international-law citation in domestic proceedings. Counsel handling permitting disputes and damages claims should expect opposing parties to deploy the opinion in pleadings filed from late 2025 onward.

Third, statute-of-limitations risk has multiplied. As courts expand standing rules for future generations and overseas plaintiffs, transactions involving long-life assets require deeper diligence for prior-era emissions disclosures.

In-house counsel now place climate-related litigation exposures on the same dashboard as antitrust and data-privacy risk. Insurance brokers report a surge in enquiries for climate-impairment cover, with several new products launched in 2024 and 2025.

Where does Malaysia fit?

Malaysia has fewer decided climate cases than Europe or the United States, but observers expect activity to rise. Federal Court judges have signalled receptiveness to public-interest litigation. The Climate Change Act 2023, gazetted on December 27, 2023, creates statutory hooks for future cases. Sabah and Sarawak state environmental boards have begun referencing international climate opinions in permit reviews.

The Malay Mail headline captured a global pivot in one phrase. Whether that pivot produces enforceable remedies in Malaysian courts will turn on cases filed within the next 12 to 18 months.
