Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the level of risk of double charging of emissions at berth under both the UK ETS and EU ETS for vessels calling at UK ports.

From 1 July 2026, the emissions from the maritime sector to which the UK Emissions Trading Scheme will apply are:

• emissions from voyages beginning and ending in the UK, and

• emissions at berth and from movements within ports in the UK.

The EU Emissions Trading System does not apply to these emissions, and so there will be no double charging of emissions under both the UK ETS and the EU ETS.
