What the ICJ Opinion Means for Loss and Damage Finance

The Fund for responding to Loss and Damage (FRLD) was established under the UNFCCC and the Paris Agreement to channel financial support to countries experiencing climate related harm. Yet its design, scale and accessibility have been questioned as climate impacts accelerate and as scientific evidence confirms that losses already exceed the adaptive capacity of many developing states. Recent advisory opinions from the International Tribunal for the Law of the Sea, the Inter American Court of Human Rights and the International Court of Justice now clarify with unprecedented precision, the legal obligations of States with respect to climate harm. Taken together, these opinions confirm that duties of prevention, cooperation, human rights protection and reparation form a binding legal framework that governs the provision of loss and damage finance. They further affirm that these obligations arise under general international law and customary international law, and therefore apply to all States, irrespective of whether they are parties to specific climate treaties.

This policy brief assesses what these advisory opinions require of the FRLD and to what extent its governance, financing structure and safeguards are consistent with clarified international law obligations. The analysis draws on doctrinal review of the advisory opinions, case law and applicable rules of international law, and secondary literature, as appropriate, as well as an institutional assessment of the Fund’s governing instrument, COP and CMA decisions, relevant climate finance norms and applicable human rights standards. This combined method allows the brief to evaluate both the legal content of States’ obligations and the institutional adequacy of the Fund through which those obligations are intended to be discharged.

Three overarching conclusions emerge. First, the advisory opinions make clear that loss and damage finance is not discretionary. It is a legal requirement that flows from the duties of cooperation and prevention and from the obligation to provide reparation when harm occurs. The Courts emphasise that financial cooperation must be adequate, predictable and commensurate with the scale of risk. Reliance on voluntary pledges or politically convenient funding structures is inconsistent with these duties.

Second, the advisory opinions significantly raise the standard of due diligence. States must act in light of clear scientific evidence, foreseeability of harm and the recognised vulnerability of affected populations. For the Fund, this means that its procedures and financing windows must enable funding disbursement for rapid and anticipatory action, support for both rapid onset and slow onset impacts and direct access modalities for communities who experience the most severe consequences of climate change. Institutional delays, burdensome access requirements or insufficient capitalisation undermine States’ ability to meet the standard articulated by the Courts.

Third, the opinions underscore that climate finance mechanisms must operate within a rights-based framework. States remain responsible for safeguarding the rights of those affected by climate harm, including procedural rights to information and participation and substantive rights to life, health, food, water, housing and culture.The Fund’s safeguard, information disclosure and stakeholder engagement and participation systems are therefore not a technical addition but part of the legal infrastructure through which States demonstrate compliance with their obligations.

The brief further clarifies that such a rights-based framework includes substantive equality and non-discrimination, participation and capacity strengthening, transparency, the production and use of data, accountability and access to justice – principles that are essential to make the gendered and intersectional dimensions of loss and damage loss and damage visible and remediable. Financing mechanisms designed through gender-neutral frameworks fail to identify and adequately remedy harms, thereby undermining the due diligence standard that these opinions reinforce.

The advisory jurisprudence from international and regional courts and tribunals leaves no doubt that the FRLD is an instrument through which States must discharge their legal duties. Its effectiveness will be judged not only by political expectations but by whether it aligns with the requirements of international law in an era of rapidly intensifying climate harm.
