The table in Figure 1 illustrates the significant volume of maritime activities occurring in ports across the Netherlands, Germany, Spain, Italy, and Norway.
Examining Figure 1 paints a compelling portrayal: the volume of vessel traffic seems to significantly outweigh the count of shore power connections, pointing to a slower rate of adoption for onshore power supply (OPS) systems. This suggests that despite the environmental advantages of OPS, the transition to this cleaner technology has been gradual. Nonetheless, within this observation, a ray of hope emerges. The European Union (EU) and the International Maritime Organization (IMO) have started to implement increasingly stringent maritime regulations, pushing the industry towards a more sustainable trajectory.
In an effort to combat greenhouse gas (GHG) emissions, the maritime industry is embarking on a progressive journey. By the year 2030, containerships and passenger ships at major EU ports are mandated to utilize on shore power supply, a move aimed at reducing emissions and promoting sustainability. Moreover, by 2034, ships’ fuel mix must incorporate at least 2% of specific renewable fuels, further bolstering the industry’s commitment to greener practices. These collective measures signify a significant step forward in the quest for a more environmentally conscious and responsible maritime sector. The noticeable upward trend signals a growing recognition of the importance of reducing emissions from vessels at berth and aligning maritime operations with global sustainability goals. While the progress may have been relatively slow initially, the evolving regulatory landscape is paving the way for a future where OPS becomes the norm rather than the exception.
Most ports worldwide aspire to achieve carbon neutrality by 2050. A considerable number of these ports have already committed to implementing shore power systems by 2028 whenever feasible. Notable ports, such as those in the North Sea region, Los Angeles, Montreal, and major Japanese ports, are among those who have signed such declarations. Cruise and container vessels are the main focus of regulations set by most ports, and the European Union (EU) will begin imposing taxes on vessels through the EU Emission Trading System (ETS) starting from the following year. These measures represent a significant effort to address emissions and promote sustainable practices within the maritime industry.
An in-depth analysis of vessel traffic data reveals intriguing insights into the vibrant maritime activities occurring in various ports around the world. Among the regions capturing the spotlight, the Netherlands emerges as a powerhouse of maritime commerce, with its ports witnessing the highest constant influx of ships, fueling global trade.
The port of Rotterdam is accountable for nearly 14 million tonnes of CO2 emissions annually, making it equivalent to Europe’s fifth largest industrial polluter, the Weisweiler coal power plant in Germany. However, the port authority has also set ambitious targets for the installation of shore-to-ship power systems. The Municipality of Rotterdam and the Port of Rotterdam Authority are jointly implementing shore-based power for sea-going vessels. By 2030, they aim to have a significant number of vessels using shore power while moored at the port’s quays, reducing air pollution and carbon footprint. Over the next five years, they will initiate projects to accelerate and expand the adoption of shore-based power. The plan represents a major step towards sustainability in the port, improving air quality and living conditions for residents and surrounding nature areas.
The partners’ shore-based strategy has three pillars:
1. Fitting public quays in built-up areas with power points, aiming for 90% usage by 2030.
2. Creating new power capacity for specific vessel types to reach 90% utilization by 2030.
3. Focusing on innovations for challenging vessel categories. The plan requires an estimated $137 million investment, with around $55 million from public funding.

Germany’s economy is closely intertwined with international trade, making maritime traffic a crucial aspect. Given its strong emphasis on exporting goods, the smooth functioning of maritime activities becomes pivotal for supporting the country’s GDP. Germany’s ports and maritime infrastructure play a vital role as key trade hubs; however, this also means they contribute significantly to climate pollution.
Striking a balance between economic prosperity and environmental responsibility is crucial as Germany navigates the challenges of maintaining its trade dominance while actively addressing climate pollution. German port initiatives include an onshore power facility for cruise ships under construction at Rostock-Warnemunde; ten facilities to be built at Hamburg for onshore power; plans for eight facilities for merchant ships at Bremerhaven.
