A policy brief published by reports on 2 November 2026 examines how the European Union’s revised Emissions Trading System could be used to scale e-fuels for shipping and aviation.
The paper takes as its starting point the ETS review proposal published in July 2026, which the European Commission has framed as an effort to make the bloc’s chief climate policy fit for its 2040 targets and to recast the ETS as an "engine for innovation and investment".
The brief isolates the investment dimension of that proposal, setting out a focused analysis of how changes to the ETS might affect capital flows directed at synthetic fuels often described as e-fuels.
Its central concern is the strategic potential of e-fuels for the two hard-to-abate transport sectors named in the title, shipping and aviation, and how regulatory design could steer financing and project development at scale.
The paper does not itself set new policy but examines the ways in which the ETS review could be deployed to attract private and public investment into technologies and supply chains associated with e-fuel production and uptake.
Strategic role for e-fuels
The brief frames e-fuels as a strategic option for decarbonising long-range modes of transport that have limited near-term alternatives, and it considers the conditions under which ETS reform might help create a credible market signal for their development.
By focusing on investment, the authors place emphasis on the follow-through from policy announcements to bankable projects, and on the need for regulatory clarity that reduces investor uncertainty while aligning with the 2040 objectives set out in the wider climate framework.
The ETS as an investment mechanism
Drawing on the July 2026 proposal, the brief explores the ways the ETS could be used beyond compliance pricing to mobilise capital, including mechanisms that link carbon policy design with direct incentives for low-carbon fuel pathways.
The paper makes clear that the ambition to turn the trading system into an "engine for innovation and investment" is a deliberate policy aim of the review, and it treats that ambition as a lens through which to assess trade-offs and policy options affecting shipping and aviation.
Taken together, the analysis aims to inform the ongoing policy debate by clarifying the investment-related consequences of different ETS configurations, and by identifying where further technical work may be required to convert regulatory intent into deployable projects.
reports’s report is presented as a contribution to a fast-moving discussion about how Europe’s central carbon market can support strategic fuel technologies while remaining coherent with broader climate goals, notably the 2040 targets referenced in the review proposal.
For policymakers and industry stakeholders engaged in the maritime and aviation sectors, the brief provides a concentrated assessment of the investment question rather than a roadmap of specific interventions, and it underscores the importance of aligning market design with long-term decarbonisation objectives.
The publication of the brief on 2 November 2026 arrives amid continuing deliberation over the ETS review and its implications for sectors where decarbonisation pathways are complex and capital intensive, and it seeks to sharpen attention on the investment levers within the proposed reforms.
