UK ETS for Shipping: Compliance Requirements and Timeline
The UK Emissions Trading Scheme (UK ETS) is the United Kingdom’s carbon pricing mechanism, introduced in 2021 following the UK’s departure from the EU ETS. From 1 July 2026, the scheme expands to cover maritime transport, requiring operators to surrender UK ETS allowances for eligible emissions from voyages involving UK ports.
UK ETS: Scope and Coverage
✓ Applies to vessels ≥ 5,000 GT
✓ 100% of emissions at berth in UK ports
✓ 100% of emissions from voyages between two UK ports

FAQs
Frequently Asked Questions about UK ETS for Shipping
The UK Emissions Trading Scheme (UK ETS) is the United Kingdom’s carbon pricing system. From July 2026, it applies to maritime transport, requiring shipping companies to monitor emissions and surrender UK Allowances (UKAs) for covered voyages.
For most operators, however, UK ETS is not simply another reporting requirement. It becomes part of a growing landscape of carbon regulations alongside EU ETS and FuelEU Maritime. The real challenge is ensuring all three schemes use consistent emissions data while avoiding duplicate administrative work.
Learn how OceanScore helps companies manage UK ETS, EU ETS and FuelEU Maritime in a single compliance workflow.
The maritime extension enters into force on 1 July 2026, with reporting beginning immediately. The first verified emissions report is due in March 2027, while the first surrender of allowances takes place in April 2028.
The scheme applies to vessels of 5,000 GT and above calling at UK ports.
* 100% of emissions from voyages within the UK
* 100% of emissions while at berth in UK ports
* 50% of emissions between Great Britain and Northern Ireland
No. Shipping companies trading between the UK and the EU may need to comply with both schemes.
Rather than treating each regulation as a separate process, many operators are looking for ways to manage all carbon compliance obligations through one trusted dataset. This reduces reporting effort, improves consistency and supports better commercial decision-making.
Contact OceanScore to see how Compliance Manager integrates UK ETS with EU ETS and FuelEU Maritime.
UK ETS uses UK Allowances (UKAs) rather than EU Allowances (EUAs).
Yes. Offshore vessels are planned to be included from January 2027.
Although UK ETS currently has a smaller financial impact than EU ETS for many operators, it introduces similar reporting, verification and allowance management requirements.
Managing each regulation in separate spreadsheets or systems increases administrative effort and creates opportunities for inconsistencies. A unified compliance process allows companies to calculate emissions once and use the same verified data across multiple regulatory schemes.
