‘(Bio)fuelling up’: The <i>Palm Oil</i> disputes and the WTO's first encounter with the EU Green Deal

Abstract Malaysia and Indonesia initiated disputes before the World Trade Organization (WTO) challenging amendments that the EU made to its Biofuel Regime. These amendments form part of a broader legislative package designed to operationalise the EU's legally binding commitment to climate neutrality by 2050 under the European Green Deal. The resulting Palm Oil panel reports represent a significant moment in WTO jurisprudence, marking the organisation's first substantive engagement with measures adopted pursuant to the EU Green Deal; and, more broadly, with climate change regulation framed as trade‐restrictive environmental policy. This article argues that the panel reports demonstrate a notable receptivity to the distinctive characteristics of climate change and climate governance. That receptivity is reflected in three key interpretative developments. First, the panels drew upon international climate law to establish a ‘sufficient nexus’ between the EU and the objective of limiting indirect land‐use change (ILUC)‐related greenhouse gas emissions, thereby accommodating the global nature of climate harm within WTO disciplines. Second, the panels adopted a ‘material contribution’ standard under Article 2.2 of the Agreement on Technical Barriers to Trade (TBT Agreement), transplanting a concept traditionally associated with Article XX of the GATT 1994 into the TBT context. This move signals a greater openness to precautionary regulatory action in circumstances of scientific uncertainty. Third, in assessing the French TIRIB tax measure under the Agreement on Subsidies and Countervailing Measures (ASCM), the panels exhibited sensitivity to the climate‐policy rationale underlying the measure, particularly in their selection of analytical benchmarks. This article asks whether the Palm Oil panel reports signal an emerging doctrinal accommodation of climate governance within WTO law, and, if so, what implications this has for future Green Deal measures. Taken together, these interpretative choices suggest an emerging judicial willingness within WTO dispute settlement to accommodate climate‐oriented regulatory autonomy, provided that such measures are structured and administered in a manner that does not constitute arbitrary or unjustifiable discrimination or a disguised restriction on international trade.
