Last week we posed five questions shipping should be asking ahead of the European Commission’s long-awaited review of the EU Emissions Trading System (EU ETS). The proposals have now been published and, while not every question received a definitive answer, a much clearer picture has emerged of where European climate policy is heading.
The review was never just about shipping. It was about the future of Europe’s carbon market, one that underpins billions of tonnes of future emissions allowances and hundreds of billions of euros of investment. The Commission’s challenge was to respond to mounting concerns over industrial competitiveness, without undermining confidence in carbon pricing as Europe’s principal decarbonisation tool.
The answer was that rather than weakening the EU ETS, the Commission has chosen to reshape it. Carbon pricing remains central to European climate policy, but the emphasis has moved towards using the market and EU ETS revenues to stimulate investment in industrial decarbonisation, rather than simply penalising emissions and pocketing the cash.
Our first question asked whether Brussels would tackle the so-called ‘port hopping’ loophole. Here, the Commission has clearly perceived there is a problem. Measures aimed at reducing carbon leakage demonstrate a recognition that the environmental credibility of the ETS depends upon preventing operators from avoiding carbon costs by diverting cargo through nearby non-EU ports. The debate over the details and whether the proposals go far enough will continue, but the issue has now firmly entered mainstream policy.
The second question concerned whether the ETS would begin to expand beyond the current 5,000 GT threshold. Rather than proposing an immediate extension, the Commission has launched an impact assessment examining whether the scheme should be widened to include ships between 400 GT and 5,000 GT. The review, which is due to report before 31 December 2031, will ‘examine the feasibility and economic, environmental and social impacts’ before any legislative proposal is brought forward.
Third was the Market Stability Reserve (MSR). Although often regarded as a technical aspect of the ETS, the proposed changes to the MSR are positive and highly relevant to shipping as they will make carbon prices less volatile while maintaining confidence in the market. For shipping companies facing multi-million-euro annual carbon liabilities, predictable carbon prices are almost as important as the actual price because they underpin investment decisions, charter negotiations, fleet renewal strategies and alternative-fuel investment decisions.
Shipping has long argued that revenues generated by the sector should be recycled into maritime fuels, infrastructure and technology and our fourth question asked whether a greater share of ETS revenues would be used to finance the transition. While some shipping and port commentators have been disappointed that funds have not been ear-marked for the sector, the review expands the ETS as a source of investment capital for all sectors. Measures include the formation of an Industrial Decarbonisation Bank, an Investment Booster and continued support via the Innovation Fund and Modernisation Fund. The review also proposes that a greater share of ETS revenues should support industrial decarbonisation.
The fifth question may ultimately prove the most significant for Maritime Carbon Intelligence readers because it extends well beyond shipping compliance.
Alongside the ETS reforms, the Commission has continued integrating industrial carbon management into Europe’s climate strategy. The wider review considers the treatment of carbon capture, utilisation and storage (CCUS), greenhouse gas removals and the accounting of captured COâ‚‚ within the ETS framework. At the same time, industry has continued to press for solutions to the so-called “double penalty”, whereby companies investing in CCS can still face ETS liabilities if captured COâ‚‚ cannot be transported or permanently stored because downstream infrastructure is unavailable.
For shipping, this has implications that extend well beyond emissions reporting.
As Europe builds a carbon management economy, demand will grow not only for low-carbon fuels but also for COâ‚‚ transport, offshore storage infrastructure and robust chain-of-custody systems. Under this scenario, carbon itself increasingly becomes a managed commodity rather than simply an emission to be avoided. This creates opportunities across the maritime value chain, from dedicated COâ‚‚ carriers and port carbon hubs to onboard carbon capture systems and the verification frameworks needed to support them.
Finally, what does the review say about Europe’s wider climate ambition? Rather than significantly strengthening or weakening the ETS, the Commission has largely sought to improve its operation while maintaining the overall direction of travel. Despite growing political pressure to reduce regulatory burdens, the review confirms that carbon pricing remains central to European climate policy. For shipping, the message is that decarbonisation will continue to be driven by economic measures, even if the mechanisms themselves continue to evolve.
The review also reinforces another important principle. The EU ETS was never intended to become a permanent substitute for global regulation. The Commission has again indicated that, should the IMO ultimately adopt a sufficiently robust global market-based decarbonisation framework delivering equivalent environmental outcomes, it would review the need for the ETS. However, until the IMO’s Net-Zero Framework is formally adopted, the EU ETS remains the principal carbon pricing mechanism applying to international shipping and will continue to shape commercial and investment decisions for the foreseeable future.
For shipping, this is probably the review’s most important message.
The future of maritime decarbonisation will not be determined solely by the price of carbon or the cost of compliance. It will increasingly depend on whether the ETS succeeds in directing investment into the fuels, bunkering infrastructure, carbon management systems and technologies needed to make low-carbon shipping commercially viable. The review suggests that Europe now sees the carbon market not simply as a mechanism for reducing emissions, but as the principal means of financing the industries that will ultimately replace them.
