This Friday, the European Commission is expected to publish its long-awaited review of the EU Emissions Trading System (EU ETS). While much of the political debate will inevitably focus on heavy industry and power generation, the maritime sector should pay close attention. The review is likely to reveal as much about the future direction of European climate policy as it does about the shipping provisions of the ETS itself.
When shipping entered the EU ETS in January 2024, the legislation was always intended to be reviewed. The Commission committed to assessing whether the system was functioning as intended, whether carbon leakage was occurring and whether further measures would be required to protect its environmental integrity.
The political landscape has changed considerably since then.
The IMO’s proposed Net-Zero Framework has yet to be adopted, leaving Europe with the only operational carbon pricing mechanism currently applied to international shipping. At the same time, pressure has grown from across European industry over the cumulative cost of climate regulation, with businesses warning that high carbon prices and rising compliance costs are affecting competitiveness and investment decisions.
The Commission therefore faces a delicate balancing act. It must preserve confidence in carbon pricing as one of Europe’s principal decarbonisation tools while responding to growing calls to simplify regulation and reduce the burden on European businesses. Shipping finds itself at the centre of that debate.
Against that backdrop, there are five questions the maritime industry should be asking when the proposals are published.
The first is: will the Commission close the so-called “port hopping” loophole? Since shipping entered the ETS, concerns have grown that some operators could reduce their carbon costs by making calls at nearby non-EU ports before entering the European market. If Europe intends to remain the leading jurisdiction for maritime carbon pricing, protecting the integrity of the scheme by addressing carbon leakage will almost certainly remain a priority.
The second question is: will the scope of the ETS will begin to expand? The Commission is expected to consider lowering the current 5,000 gross tonnage threshold to include vessels between 400 GT and 5,000 GT, potentially bringing many offshore support vessels, coastal operators and smaller cargo ships into the system for the first time. While unlikely to affect the largest shipowners immediately, such a move would extend carbon pricing into sectors of the maritime industry that have so far remained outside the scheme.
Third: will the Commission take steps to increase the stability of carbon pricing? Shipping should pay close attention to proposals affecting the Market Stability Reserve (MSR). Although primarily a feature of the wider ETS, the reserve has a direct bearing on carbon allowance prices. For shipowners currently facing carbon liabilities running into millions of euros each year, a predictable carbon price is almost as important as the price itself. Greater price stability would improve investment planning, charter negotiations and long-term decisions on fleet renewal and alternative fuels.
The fourth question concerns revenues: will the Commission use more of the revenue raised from the ETS to finance the energy transition? Maritime participation in the ETS is generating billions of euros for European governments. The industry has consistently argued that a greater proportion of those revenues should be recycled into shipping through investment in low-carbon fuels, bunkering infrastructure, port facilities and decarbonisation technologies. Friday’s review may provide an indication of whether the Commission sees the ETS simply as a carbon pricing mechanism or as a means of financing the transition itself.
Finally, what is the future strength and direction of Europe’s environmental ambition? The review may provide the clearest indication yet of Europe’s wider regulatory direction. With the IMO’s Net Zero Framework still awaiting agreement, the EU ETS and FuelEU Maritime remain the principal economic drivers of shipping decarbonisation. The Commission must now decide whether to strengthen those measures, simplify them or seek a balance between environmental ambition and industrial competitiveness. That decision will influence investment across the maritime value chain, from fuel producers and bunker suppliers to shipowners, ports and financial institutions.
The irony is that a review originally intended to fine-tune shipping’s participation in the EU ETS has become something much larger. It now represents one of the first opportunities to see how Europe intends to respond to a world in which global carbon regulation remains uncertain, while pressure on European industry continues to grow.
For shipping, Friday’s announcement will therefore be about far more than compliance obligations. It will offer an early indication of how the European Commission intends to balance decarbonisation with competitiveness, market stability and investment confidence. Whatever the detailed proposals, they are likely to shape the commercial environment in which maritime decarbonisation develops for the foreseeable future.
