The Link Between Engine Efficiency and Emissions Marine engines, especially those powering large cargo and container ships, primarily run on heavy fuel oil—a type of fossil fuel with high carbon content. Inefficient combustion in these engines leads not only to increased carbon dioxide (CO₂) emissions but also to other pollutants such as nitrogen oxides (NOₓ), sulfur oxides (SOₓ), and particulate matter.

Improving the efficiency of marine engines means getting more propulsion and power output from the same amount—or less—fuel. This reduces the amount of fuel burned per voyage, directly decreasing emissions. For instance, a 10% improvement in fuel efficiency can lead to roughly a 10% reduction in CO₂ emissions.
Key Drivers of Marine Engine Efficiency Several technologies and strategies are being developed and implemented to boost marine engine efficiency:
