Abstract The 2023 revision of the EU Horizontal Guidelines introduced a dedicated framework for sustainability-oriented cooperation agreements, marking the first systematic attempt to integrate environmental objectives into EU competition law. Yet, almost two years after they entered into force, DG COMP has not received a single request for informal guidance under the new provisions. This policy commentary explains this apparent policy failure by reconstructing the process through which sustainability concerns entered EU competition policy after the 2019 European elections and the European Green Deal. Drawing on historical-institutionalist process tracing, we show that the resulting adjustments were shaped by political urgency rather than gradual policy learning, and that the 2023 Guidelines reflected cautious compromise rather than transformative change. We then analyse why uptake has remained negligible: multinational firms face steep cross-border enforcement risks, particularly from jurisdictions such as the United States, where sustainability agreements can trigger antitrust liability. We conclude by assessing the EU’s strategic options (retreat, international convergence, or domestic regime stabilisation) and argue that the last of these offers the most realistic path.
