Qatar has formally deposited its instrument of accession to MARPOL Annex VI, the IMO regime on preventing air pollution from ships. The move extends global coverage of emission controls and signals stricter environmental compliance expectations for LNG‑linked shipping serving one of the world’s largest energy exporters.
On September 9, 2026, Qatar announced that it has deposited its instrument of accession to MARPOL Annex VI with the International Maritime Organization, bringing the country under the IMO framework that regulates air emissions from ships. Annex VI covers limits on sulphur and nitrogen oxides, fuel sulphur caps, the establishment of Emission Control Areas (ECAs), and energy‑efficiency requirements for ships. Accession means that Qatari‑flagged vessels and foreign ships operating under Qatari jurisdiction must comply with these standards, including the global 0.50% sulphur limit and technical rules on engine NOx emissions. The step was highlighted by Qatar’s official news agency as part of a broader national strategy to curb the environmental footprint of its energy sector and align maritime activities with IMO decarbonization objectives toward mid‑century.
