Nestled on reclaimed North Sea land at the delta of the Rhine and Meuse rivers, the Port of Rotterdam stands as Europe’s undisputed freight powerhouse. By volume, this massive logistics hub handles nearly as much annual cargo as all United Kingdom ports combined. Its skyline is defined by towering container cranes, stacked shipping boxes, and massive bulk carriers – the front-facing infrastructure of one of the world’s largest integrated energy and chemical complexes.
Five major oil refineries, anchored by Shell’s largest European processing facility, collectively process hundreds of thousands of barrels of crude oil every day, while a dense network of chemical plants supplies manufacturing operations across the European continent. Research from independent environmental research firm CE Delft links the full lifecycle carbon emissions of fossil fuels passing through Rotterdam to roughly 600 megatonnes of carbon dioxide annually – a figure multiple times higher than the annual emissions of the Netherlands’ busiest airport, Schiphol.
This outsized carbon footprint has positioned Rotterdam as a global test case for one of the energy transition’s most pressing questions: Can a port built entirely around the fossil fuel economy ever make a full, authentic shift to sustainable operations? Growing pressure from climate activists is pushing port leadership to confront this challenge head-on, culminating in a high-profile lawsuit filed by Dutch environmental group Advocates for the Future. The suit argues the Port of Rotterdam Authority has failed to take sufficient action to phase out fossil-based energy flows, and demands a legally binding, concrete roadmap to wind down coal, oil and gas throughput – emissions from which already outpace the total national emissions of most of the world’s countries.
Port officials acknowledge the scale of the problem. Mark van Dijk, head of external relations for the Port of Rotterdam Authority, confirms the port’s industrial cluster currently emits roughly 29 million tonnes of CO2 annually, accounting for half of the Netherlands’ entire domestic emissions. “It’s not good,” van Dijk admits, putting the figure in perspective: the annual emissions equal that of tens of thousands of round-trip passenger flights between Amsterdam and Los Angeles.
Port leadership has already laid out a formal decarbonization plan targeting its own operations and aiming to encourage lower-emission practices among on-site businesses. The authority has set a target to cut its direct and purchased energy emissions by 90% between 2019 and 2030. Key initiatives include developing a dedicated hydrogen hub to allow companies to test and scale low-carbon fuel technologies, investing in onshore shore power infrastructure that lets docked ships turn off their polluting auxiliary engines and connect to the local electrical grid, and supporting the adoption of alternative bunker fuels including liquefied natural gas, biofuels and methanol.
To address existing industrial emissions in the near term, the port is prioritizing Carbon Capture and Storage (CCS), which involves capturing carbon emissions from industrial facilities and storing them permanently in depleted offshore gas fields via the port’s Porthos project.
But activists reject the port’s incremental approach. Maikel van Wissen, director of Advocates for the Future, argues a port of Rotterdam’s scale and influence carries a unique responsibility to accelerate the clean energy transition, rather than simply continuing to manage ongoing fossil fuel flows. “A state-owned enterprise should take on the same legal obligations that governments have to reduce emissions,” van Wissen says. “We are asking in the lawsuit to phase out that dependency, to create alternatives. It takes time, but if you don’t have a plan, you always choose cheap short-term solutions. This is an important hub, if you do it in a controlled way, you offer an alternative, that will stop industry from moving elsewhere.”
Port officials counter that they are already actively reshaping the port’s business model to prioritize decarbonization. “We try to work together with the polluters, and slowly phase them out,” says Oscar van Veen, the port’s director of innovation, before correcting himself: “As fast as possible, of course.”
Still, the transition faces steep structural and geopolitical barriers. Many of the port’s largest emitting facilities are owned by multinational corporations headquartered in the United States, China and other countries, whose primary loyalties lie with their global boardrooms. If regulations become too stringent in Rotterdam, companies can simply relocate operations – a precedent already set when Shell moved its global headquarters to the United Kingdom and consumer goods giant Unilever left Rotterdam entirely.
Bettina Kampman, a senior analyst at CE Delft, notes that the Port of Rotterdam Authority’s influence over independent on-site operators is inherently limited. Even expanding the port’s own low-emission infrastructure faces significant bottlenecks. “New developments need physical space. They can speed up the energy infrastructure developments – the electricity needed to electrify the processes. That’s all limited at the moment due to the lack of power cables,” Kampman explains.
Harry Geerlings, emeritus professor of sustainable transport and ports at Erasmus University Rotterdam who has studied the sector for more than 30 years, argues no single port authority can deliver a full energy transition on its own. What is required, he says, is a global level playing field, similar to the regulatory frameworks the European Union has already established through the EU Emissions Trading System and international marine fuel sulphur standards.
Geerlings points to the EU’s sulphur regulations as a proof of concept: when new rules required all ships calling at European ports to switch to lower-sulphur fuels or install pollution-control scrubbers, major shipping nations including China eventually complied after initially resisting, once their vessels were barred from major global ports without meeting the standards. “If you have the right incentives, you change the behaviour of these companies,” he says.
Even with effective regional regulation, loopholes remain: many shipping lines now use dual-fuel engine setups, switching to cleaner low-sulphur fuel only when entering EU territorial waters, then reverting to cheaper high-sulphur heavy fuel oil once they reach the unregulated high seas.
Geerlings says he believes Rotterdam’s port leadership is genuinely committed to decarbonization and is already investing in the infrastructure needed to support a smoother transition. Still, he notes a core, unresolved dilemma: “But their biggest income is still tied to fossil fuel industries. It’s not simply a switch you turn on or off. A port needs activity as a logistics node – otherwise it’s no longer a port. It’s a real dilemma.”
Geopolitical tensions have further complicated the transition. Former U.S. President Donald Trump’s skepticism of aggressive climate policy and financial incentives favoring fossil fuels over renewables have amplified Rotterdam’s fears that energy-intensive industries will relocate to regions with weaker environmental regulations and lower energy costs.
Activists argue that as a publicly owned entity, the Port of Rotterdam Authority should be held to a higher environmental standard than private operators. They are not asking for an immediate full shutdown of all fossil fuel operations, but rather a detailed, time-bound phase-out plan – not just a long-term promise to reach climate neutrality by 2050. “We are not asking for anything extraordinary,” van Wissen says. “We’re asking for a plan that really contributes to a sustainable future for the port.”
For their part, port officials say they share the same end goal. Speaking during an electric taxi ride back to Rotterdam from the port’s outer edge, van Dijk stresses that both the port authority and its critics are aiming for the same destination: net-zero emissions by mid-century. The core disagreement, he acknowledges, is over how quickly the transition needs to happen, and how radical the changes to the port’s existing business model need to be.
