This briefing examines how the Investor-State Dispute Settlement (ISDS) system hinders climate action and human rights by allowing corporations, particularly in the fossil fuel sector, to sue governments over environmental regulations. It highlights the 'regulatory chill' effect, the inadequacy of current reforms like the Energy Charter Treaty withdrawals, and the significance of 2025 advisory opinions from the ICJ and Inter-American Court of Human Rights which affirm state duties to reduce emissions regardless of prior investment licenses.

This briefing note from the Center for International Environmental Law outlines the legal obligations of States to protect the ocean from climate change by halting fossil fuel expansion and phasing out their use. It highlights the significance of climate advisory opinions from the International Tribunal for the Law of the Sea (ITLOS), the International Court of Justice (ICJ), and the Inter-American Court of Human Rights in establishing these duties.

This briefing by the Center for International Environmental Law (CIEL) analyzes the 28th session of the Conference of the Parties (COP28) in Dubai, focusing on the integration of human rights in climate policies. The report argues that the conference was undermined by the host country's restrictive civic space and corporate capture by the fossil fuel industry, leading to outcomes on fossil fuel transitions and the Loss and Damage Fund that are insufficient and flawed.

A joint analysis by the Center for International Environmental Law (CIEL) and the Heinrich Boell Foundation examining the discrepancies between the IPCC Working Group III report's consensus and the mitigation pathways presented in its Summary for Policymakers.

This executive summary outlines research by the Tyndall Centre at The University of Manchester on phaseout pathways for oil and gas production to align with Paris-compliant carbon budgets and the 1.5°C goal.

An open letter from 252 legal experts to the participants of the First Conference on Transitioning Away from Fossil Fuels, asserting that states have binding international legal obligations to phase out fossil fuels to prevent significant climate harm.

This open letter, published by the Center for International Environmental Law (CIEL), is addressed to the participants of the First Conference on Transitioning Away from Fossil Fuels in Santa Marta, Colombia. It features a collection of statements from legal experts, academics, and policy advisors who argue that phasing out fossil fuels is a binding legal obligation under international law, rather than a matter of political discretion. The document emphasizes that current approvals for new fossil fuel projects and the continued use of subsidies violate international legal duties to prevent climate harm and protect human rights.

This policy brief by the Center for International Environmental Law (CIEL) argues that Investor-State Dispute Settlement (ISDS) mechanisms act as a major legal and financial barrier to climate action. It contends that ISDS allows fossil fuel investors to sue governments for implementing climate regulations, creating a "chilling effect" that deters states from phasing out fossil fuels and aligning financial flows with the Paris Agreement.
