The Port of Rotterdam, the largest freight port in Europe and a major fossil-fuel, energy and chemicals hub, is facing growing pressure to accelerate its shift away from oil, coal and gas. A lawsuit brought by the environmental group Advocates for the Future argues that the Port of Rotterdam Authority is not doing enough to phase out fossil-based energy and is demanding a concrete plan to wind down these flows. The case has turned the port into a test case for whether an economy built on fossil fuels can genuinely become green, a question with implications well beyond the Netherlands.

The port's own industrial cluster emits around 29 million tonnes of CO2 a year — roughly half of the Netherlands' domestic emissions — while research by CE Delft links the fossil fuels passing through it to about 600 megatonnes annually. The Authority has set a target to cut its own direct and purchased energy emissions by 90% between 2019 and 2030, with plans including a hydrogen hub, onshore power for berthed ships, alternative fuels such as LNG and methanol, and carbon capture via the offshore Porthos project. However, officials and analysts note the port's influence is limited: many big emitters answer to headquarters in the US or China and could relocate, as Shell and Unilever have done, while experts argue that only a global level playing field — like EU sulphur rules that reshaped shipping behaviour — can drive a full transition.
