UK Emissions Trading Scheme: Shipping

Asked by Jerome MayhewConservativeDepartment for Energy Security and Net ZeroTabled Answered 15 June 2026UIN 7518

The question

To ask the Secretary of State for Energy Security and Net Zero, how many unresolved (a) technical and (b) compliance queries his Department has identified relating to the maritime extension of the UK Emissions Trading Scheme; and what steps his Department is taking to provide definitive guidance to operators ahead of implementation.

Answered by Chris McDonald

The Government has built a high-quality digital-first system with an online emissions monitoring and reporting platform that has embedded guidance for the whole process. Free voluntary onboarding has been available since November 2025 for at least 96% of operators.

The regulators have also published five maritime newsletters, YouTube tutorial videos and hosted webinar Q&A sessions.

The Environment Agency, as regulator for the majority of maritime operators, operates a dedicated maritime helpdesk and reports on query themes to inform ongoing guidance.

The Government does not hold a central record of individual operator queries.
