EU ETS for Offshore Ships from 2027

Offshore ships of 5,000 GT and above enter the EU Emissions Trading System on 1 January 2027, when the Annex I exception for activities under Article 2(1b) of Regulation (EU) 2015/757 expires. They have monitored and reported emissions under the MRV Regulation since 1 January 2025, and they surrender 100% of their in-scope emissions from their first year, with no 40% or 70% phase-in. Article 3(z) of Directive 2003/87/EC counts a stop where an offshore ship relieves its crew as a port of call.

Offshore ships of 400 to 5,000 GT report under MRV Article 2(1a) and are outside the ETS; Article 3gg(5) requires a Commission report on including them by 31 December 2026. Proposal COM(2026) 616 would treat offshore worksites as ports of call.

The full article will cover the offshore ship categories, voyage and worksite treatment, and the contract allocation of allowance costs in offshore charters. See EU ETS maritime scope and phase-in .
