The First Conference on Transitioning Away from Fossil Fuels: Reclaiming Multilateralism for a Just Transition

Informal Note, 28 April 2026

By Daniel Uribe Terán

The First Conference on Transitioning Away from Fossil Fuels, co-hosted by Colombia and the Netherlands, serves as a necessary platform for reclaiming multilateralism for a just transition. This paper analyses how the conference addresses the ‘judicialization’ of climate obligations following landmark 2025 advisory opinions from the International Court of Justice (ICJ), the International Tribunal for the Law of the Sea (ITLOS), and the Inter-American Court of Human Rights (IACtHR). It highlights critical barriers facing developing countries, specifically the ‘regulatory chill’ caused by Investor-State Dispute Settlement (ISDS) mechanisms and the ‘debt-fossil fuel trap’ that binds extractive economies to external risks. It also recognises that integrating the ‘People’s Summit’ outcomes into the official Conference could promote a reparative financial model and strengthen the principle of Free, Prior, and Informed Consent (FPIC). Ultimately, Santa Marta should provide a blueprint for systemic reform, ensuring that global decarbonisation respects resource sovereignty and human dignity while moving toward a coordinated, legally backed effort for collective survival.

The Role of Advisory Opinions in Shaping International Climate Change Law

By Daniel Uribe Terán

This policy brief analyses how advisory opinions (AOs) from the International Court of Justice (ICJ), the International Tribunal for the Law of the Sea (ITLOS), and the Inter-American Court of Human Rights (IACtHR) are fundamentally reshaping international climate law. These AOs are crystallising States’ climate commitments, transforming them from voluntary political pledges into binding legal obligations grounded in customary international law and human rights. This judicial shift establishes stringent, science-based due diligence standards, confirms State responsibility for harm, and provides a powerful legal foundation for accountability and reparation.
