1. In the event of the adoption by the International Maritime Organization (IMO) of a global market-based measure to reduce greenhouse gas emissions from maritime transport, the Commission shall review this Directive in light of that adopted measure.

To that end, the Commission shall submit a report to the European Parliament and to the Council within 18 months of the adoption of such a global market-based measure and before it becomes operational. In that report, the Commission shall examine the global market-based measure as regards:

(a) its ambition in light of the objectives of the Paris Agreement;

(b) its overall environmental integrity, including in comparison with the provisions of this Directive covering maritime transport; and

(c) any issue related to the coherence between the EU ETS and that measure.

Where appropriate, the Commission may accompany the report referred to in the second subparagraph of this paragraph with a legislative proposal to amend this Directive in a manner that is consistent with the Union 2030 climate target and the climate-neutrality objective set out in Regulation (EU) 2021/1119, and with the aim of preserving the environmental integrity and effectiveness of Union climate action, in order to ensure coherence between the implementation of the global market-based measure and the EU ETS, while avoiding any significant double burden.
