By issuing Royal Decree 611/2026, Spain has joined the ranks of leading countries in implementing greenhouse gas reduction regulations for marine fuel suppliers. This action follows similar laws in the Netherlands that came into effect in January 2026 and significantly impacted the fuel market at the Port of Rotterdam.
Impacts of Royal Decree 611/2026
The Royal Decree mandates marine fuel suppliers in Spain to reduce the greenhouse gas intensity of marine fuels. This reduction will start at a rate of 6.5% in 2027 and increase to 33% by 2040. Additionally, Spanish ports will be required to report annually on the type of fuel and electricity they supply.
According to market data, since the implementation of the Dutch laws, fuel sales at the Port of Rotterdam have sharply declined, reaching 648,399 tons in the first quarter of 2026, the lowest level since 2009. This decrease, due to the absence of similar regulations in other countries like Belgium and Germany, has led to a significant shift of fuel volumes from Rotterdam to ports without similar regulations.
International Challenges and the Need for Coordination
The timing of the implementation of these laws in Spain is particularly sensitive. Efforts by the International Maritime Organization (IMO) to establish a unified global mechanism for reducing greenhouse gases have faced setbacks in recent meetings. The issue of voting on the adoption of these regulations will again be on the agenda in upcoming meetings in November and December 2026.
PortXchange CEO, Sjoerd de Jaeger, stated: "Spain is following the Dutch model. This trend shows that without coordination, fuel volumes will shift to areas with less regulation. The industry needs to take necessary actions before December, not after. This is not just a policy preference, but a survival strategy."
With the implementation of these regulations in Spain, widespread effects on the marine fuel market and global greenhouse gas reductions are anticipated. PortXchange provides analytical tools to ports and operators, enabling the identification and analysis of shifts.
