Shipping Decarbonization
Coverage from Cyprus Shipping News, El Estrecho Digital, and others
Shipping produces roughly 3% of global greenhouse-gas emissions and remains heavily dependent on fuel oil and other carbon-intensive energy sources.
The transition is shaped by International Maritime Organization negotiations over the Net-Zero Framework, including progressively stricter fuel standards and proposals for fees on emissions above defined limits. These measures raise questions about the availability and cost of low-emission fuels, the role of LNG, investment in vessels and infrastructure, the effect on trade, and how revenues could support cleaner technologies and climate-vulnerable countries. Major flag states and national governments remain divided over the pace, design, and distributional consequences of the transition.
