Building a fossil fuel non-proliferation treaty: key elements

Amid growing recognition of the need for supply-side policies which set limits on the further expansion of fossil fuel extraction and use, in this article we consider possible elements of a Fossil Fuel Non-Proliferation Treaty (FF NPT), behind which there is growing momentum. We elaborate on the possible institutional mechanisms, principles, procedures, and other elements of an FF NPT, by drawing on relevant precedents and parallels with other treaties and bodies of international law on the environment and other policy arenas, and proposals circulating in academic and grey literatures. We address in turn: the scope, objectives, and principles of an FF NPT; the three pillars of commitments under the treaty of (i) ending expansion, (ii) phasing out fossil fuels, and (iii) a global just transition; and options for implementation, including the review of implementation, compliance and effectiveness, a financial mechanism, institutional arrangements, and the role of non-state actors.
