There are insufficient financial incentives to stimulate investments in eco-ships (where engines are more fuel efficient) risking missing emissions reduction targets.

In this research by Clean Maritime Research Hub’s Dr Ioannis Moutzouris and colleagues the price differentials are explored using data over recent years.

Policy recommendations include the need for:

• Clarity and certainty around market-based measures and alternative fuels regulations
• Green finance options to encourage investment in eco-ships
• Fossil fuel levies to discourage conventional ship use and encourage eco-ship investments
