Litigation Note on Challenging the Financing of Climate-Destructive Conduct

The document analyzes the implications of the ICJ's advisory opinion on States' obligations to prevent environmental harm, specifically focusing on the cessation of fossil fuel subsidies and the regulation of private finance. It argues that States may commit internationally wrongful acts by continuing to fund fossil fuel production or failing to regulate private financiers. Additionally, it outlines binding obligations for developed States to provide financial assistance to developing countries for climate adaptation and mitigation under the UNFCCC and Paris Agreement. The briefing concludes by categorizing various types of climate litigation—including cases against public agencies, central banks, and private financial institutions—where these legal findings are applicable.

• The International Court of Justice (ICJ) determined that a State's failure to take appropriate measures to protect the climate system from greenhouse gas (GHG) emissions, including through the provision of fossil fuel subsidies or the granting of exploration licenses, may be considered an internationally wrongful act.
• States are under a legal obligation to use all available means to reduce GHG emissions, which includes the duty to cease continuing wrongful acts by revoking administrative, legislative, or other measures that facilitate such emissions.
• States have a due diligence obligation to regulate the conduct of private operators within their jurisdiction to prevent significant environmental harm; failure to implement necessary regulatory or legislative measures to limit emissions from private actors can result in State responsibility.
• Under the UNFCCC, State parties listed in Annex II have a legally binding obligation to assist developing countries that are particularly vulnerable to climate change in meeting the costs of adaptation.
