UK ports challenge EU carbon leakage claims: BPA says investment, not EU ETS, is driving container growth

The British Ports Association has published new analysis arguing that EU carbon pricing is not diverting container shipping from continental Europe to the UK. The paper directly challenges claims from Spain's EU ETS Observatory that British ports are benefiting from carbon leakage under the EU Emissions Trading System. The BPA says growth in UK container volumes tracks recent investment, including the new 350 million pound berth at London Gateway, rather than any shift caused by carbon costs. UK container volumes grew strongly in 2025, with around 85 percent of that growth coming through London after the new berth opened. The BPA also notes that major continental ports like Rotterdam, Antwerp-Bruges, and Hamburg recorded growth over the same period, which weakens the argument that UK gains came at their expense. The association is calling on the UK government and European Commission to look at the full data before introducing measures that could penalize British ports. The dispute matters for climate policy because it tests whether emissions trading is being used as a real decarbonization tool or as a cover for trade disputes. The BPA supports measures to cut shipping emissions, but wants the evidence base to be solid before any new penalties are applied.

The BPA's argument is basically that correlation is not causation. EU ETS critics point at UK volume growth, but the UK added a major berth at London Gateway and continental ports grew too. That is a fair challenge to the carbon leakage claim. The real question is whether the EU has actual evidence of transshipment shifting. If not, this looks like protectionism dressed up as climate policy.

One thing the article does not quantify is how much of the UK growth is transshipment versus final demand. Container numbers alone do not show carbon leakage. If cargo is just moving through Felixstowe to the same end markets, the ETS impact on actual emissions is different. Need origin-destination data, not throughput totals.

Also worth remembering the EU ETS covers maritime only for voyages within the EEA and 50% of extra-EEA trips. A UK port outside the scheme could look cheaper for a call. But the BPA's point about continental ports growing too undercuts the diversion story. Investment data should settle it, yet the EU observatory seems focused on market share.

The interesting part for carbon markets is how this gets resolved. If the EU starts penalizing UK ports without solid evidence, it sets a bad precedent for border adjustments. Climate policy needs to be based on actual emissions, not competitor complaints. Otherwise you get trade disputes that distract from real decarbonization.

Anyone have a link to the Spain EU ETS Observatory reports? The BPA response links its own paper but the original claims are not in this article. Hard to judge who has the better data without seeing the base case.
