Greenhouse Gas Emissions Trading Scheme (Amendment) (Extension to Maritime Activities) Order 2026

Debate between Earl Russell and Lord Weir of Ballyholme

Thursday 12th March 2026 Lords Chamber

[Earl Russell (LD)]

There is a reduction in place in Northern Ireland. There is not specific legislation around that.

[Lord Weir of Ballyholme (DUP)]

The noble Lord gave one of his key considerations as a test of economic fairness. Perhaps he could explain to the House how it is economically fair to have an 100% exemption for Scotland but 50% for Northern Ireland. How is that fair?

[Earl Russell (LD)]

It is not for me to respond to what is a question for the Minister. The Government’s impact assessment estimates central abatement investment of around £22 million, with administrative costs of £179 million over the period. The allowance-purchase cost is largely a transfer to the Exchequer and devolved Administrations, with many operators being non-UK based. Carbon pricing must therefore be matched with a credible transition plan. Without that, this becomes not a nudge for transition but could simply be a tax. However, the Government have announced £448 million for the UK Shipping Office for Reducing Emissions—UK SHORE—between 2026 and 2030, the largest public investment yet in commercial maritime.

Phase 2 will support larger projects through the Clean Maritime Demonstration competition and the Zero Emissions Vessels and Infrastructure competition. That is the industrial policy that must sit alongside carbon pricing. At the same time, the measure is expected, on the Government’s central estimate, to generate around £1.9 billion in allowance-sale revenue: around £95 million a year. Will the Minister confirm that a material share of ETS maritime revenues will be reinvested in maritime decarbonisation, including cleaner vessels, shore power, alternative fuels, and support for local transition in coastal and island communities, rather than simply disappearing? Will the Minister commit to publishing annually how much is raised from maritime ETS and how much is invested in maritime decarbonisation?

The cruise industry is an important and growing part of our economy, calling at some 50 UK ports and making over 2,500 calls a year, supporting tens of thousands of jobs and adding billions to the UK-wide economy. The industry’s concern on ETS is that revenues are not being visibly recycled into cleaner fuels and infrastructure specific to their industry. We only have a handful of onshore connections for cruise liners at the moment, so will the Minister tell us what investment will be made as a result of this scheme to bring shore power, and on what timetable for the cruise industry?

The Government and the UK ETS have done substantial preparatory work, including consultations, a digital monitoring platform and voluntary onboarding since November 2025, ahead of the July 2026 start. The Government’s impact assessment estimates an average administrative cost of around £5,700 per operator per year. This may be modest, but it has real implications for real firms. We recognise that this should reduce over time.

We welcome the formal review at the end of 2028 to assess emissions outcomes, administrative burdens and any needed adjustments to scope or thresholds. We have a number of specific concerns about any plans to expand the scope to international voyages. My noble friend will address the specific issues relating to Northern Ireland aspects. We believe the right approach is to keep these provisions under review and match carbon pricing with practical support, not to abandon maritime decarbonisation. Extending the UK ETS to domestic maritime emissions also helps keep our scheme aligned with greater integration with the EU. In turn, a genuinely linked system will help strengthen our trading relationship.

The fatal and regret Motions both reflect genuine anxieties about costs, competitiveness, and the union, but neither justifies rejecting this order. The suggestion that there is no alternative is not borne out by the evidence. Improved operating practices, routing efficiency and gradual fuel switching all represent viable abatement pathways.

Near-zero emission fuels remain expensive and infrastructure is incomplete. But that is exactly why revenue recycling and UK SHORE matter. The right course is to pair a robust carbon price with predictable investment that keeps the maritime sector on its net-zero path, while keeping the UK economy competitive. To call this measure simply a tax misunderstands how the ETS works. It is designed to minimise the cost of meeting our climate goals, to give business flexibility and to limit carbon leakage: this is a practical measure. It becomes a tax only if the Government pocket the proceeds and fail to reinvest them. Revenue is a byproduct: the purpose is to cap and reduce emissions over time. We are supportive of the extension of emissions trading to domestic maritime. Done well, emissions trading drives real reductions, supports innovation and underpins our net-zero transition.
