What Does the International Court of Justice Advisory Opinion on Climate Change Mean for Environmentally Harmful Subsidies?

The document argues that the ICJ Advisory Opinion transforms the removal of fossil fuel and other climate-harmful subsidies from a political commitment into a legal imperative. It recommends that states track financial support, phase out subsidies gradually, reallocate funds to green solutions, and coordinate internationally to reduce legal and political risks.

• The International Court of Justice (ICJ) Advisory Opinion establishes that ending fossil fuel subsidies is a legal imperative rather than merely a political commitment, requiring states to do everything possible to protect the climate, although their specific responsibilities may account for their available resources and capabilities.
• While the ICJ ruling explicitly mentioned fossil fuel subsidies, the reasoning is applicable to other climate-harmful financial supports, including agricultural subsidies, meaning states must phase out all domestic support that threatens the environment to mitigate legal risk.
• Governments currently spend more than USD 2 trillion every year on subsidies that negatively impact nature and climate, and have failed to meet previous pledges to phase them out.
• To effectively reduce legal risk and manage the transition, states are advised to document all harmful financial support, implement gradual phase-outs (utilizing periods of low oil prices), reallocate savings toward energy efficiency and alternative energy, and utilize international coordination mechanisms like COFFIS.
