On Tuesday, climate activist Greta Thunberg and protesters from the Danish environmental group Den Gronne Ungdomsbevaegelse briefly occupied the Copenhagen headquarters of Maersk Tankers in the Amager East district. Their protest was aimed at the company’s core business—transporting fossil fuels.

Dozens of activists entered the company’s offices, unfurled banners, and chanted slogans through megaphones. Some protesters mockingly cleaned glass partitions with spray bottles and cloths, criticizing what they described as Maersk Tankers’ "greenwashing" PR tactics.

A secondary focus of the protest targeted A.P. Moller-Maersk, which activists accused of transporting weapons to Israel—a claim echoed by other anti-war demonstrators over the past year.

Maersk Tankers is part of A.P. Moller Holding, the family-owned parent company of container shipping and port logistics giant A.P. Moller-Maersk. The tanker firm operates independently and is not affiliated with Maersk's container shipping division. As a liquid bulk operator, Maersk Tankers does not have the capability to transport weapons.

Protester Freya Skriver said, "We demand that Maersk stop shipping weapons to Israel—arms that are directly used in genocide against Palestinians—but we also want them to halt the transport of all oil and gas."

On Wednesday, around 30 activists from the Dutch group Geef Tegengas blocked the lobby of Maersk’s Rotterdam office in the morning, demanding the company stop all weapon shipments to and from Israel. They were part of a broader international campaign called "Mask off Maersk."

Spokesperson Sterre van de Berg said demonstrators chained themselves to the entrance and made noise to "disrupt Maersk’s activities and draw attention to their role." Despite the protest, Maersk employees were able to access the building. The Dutch group stated they would continue demonstrating "until Maersk stops transporting weapons to Israel." It remains unclear how long the protest will continue.

According to Nieuwsblad Transport, Maersk spokesperson Rainer Horn declined to comment specifically on the Rotterdam protest but referred to a March statement made after similar protests in Denmark.

As reported by WorldCargo News, Maersk has stated that its operations comply with international standards, including the UN Global Compact and OECD guidelines. The company noted it does not ship weapons or ammunition to conflict zones. Since the start of the Israel-Hamas conflict, Maersk has increased cargo inspections and added that its U.S. subsidiary, Maersk Line Limited, has never transported classified or sensitive military goods to Israel.
