Rotterdam and Singapore have signed a cooperation agreement for their Green and Digital Shipping Corridor, a route of approximately 15,000 kilometres. The partnership brings together 28 organisations from across the container-shipping value chain and sets a collective ambition to reduce greenhouse-gas emissions from large container vessels on the corridor by 20 to 30 per cent by 2030. This article is independently written from the cited factual information published by the Maritime and Port Authority of Singapore and the Port of Rotterdam on 25 March 2025. [1]
The agreement combines work on fuels with work on information exchange. The fuel programme covers bio- and e-variants of ammonia, methanol and methane. The partners have organised fuel-specific working groups, indicating that the corridor is being treated as several technical pathways rather than as a commitment to one replacement fuel.
The digital strand concerns port calls. Rotterdam and Singapore had already trialled port-to-port exchange of vessel-arrival and departure timestamps, together with ship-to-shore data exchange for port-clearance information. Those trials provide the operational context for the agreement, although the source does not state that a permanent system has been completed.
A corridor with two linked aims
The corridor's environmental ambition applies to large container vessels using the route. The 20–30 per cent target is collective and is set for 2030. It is not presented as a guaranteed reduction for every individual ship or voyage. That distinction matters because the agreement covers a network of partners and multiple fuel and data projects. [1]
The route length gives the collaboration a practical scale. At approximately 15,000 kilometres, the corridor connects two major maritime centres over a long-distance container service. Fuel availability, bunkering arrangements, vessel operations and port procedures therefore have to be considered together if the stated ambition is to be tested in practice.
The partners' fuel list is deliberately broad. Ammonia, methanol and methane each have bio- and e-variants in the programme. The supplied source does not identify a final fuel choice, a single vessel class or a commercial service that will deliver the target. Instead, it records a structured process for examining different options.
Digital systems form the second part of that process. Sharing arrival and departure timestamps between ports can give participants a common view of a vessel's movement. Ship-to-shore information for clearance addresses a different part of the port call. The two trials therefore relate to both visibility and administrative information exchange.
A planned Singapore trial
A similar mass-balanced liquefied bio-methane bunkering trial was planned for Singapore in 2025. The source records it as planned activity, not as a completed trial. The mass-balanced description is important because it identifies the accounting approach in the announcement without claiming that physical molecules were allocated to a particular voyage.
For the archive, the agreement marks an expansion of cooperation between Rotterdam and Singapore from general partnership into a named corridor programme. It sets a route, a group of 28 partners, an emissions ambition and defined areas of work. The announcement also records earlier digital trials and a planned Singapore bunkering exercise.
The agreement does not provide a delivery timetable for every workstream, a list of individual partners or a measured emissions result. The article therefore stays with the confirmed scope: fuel studies, digital port-call exchanges, a collective 2030 ambition and the planned bio-methane trial.
The two port authorities' announcement is the source for all factual claims in this independently written report. No port photographs, logos or other protected assets are reproduced because no reuse licence is established by the supplied packet.
