Sustainability Outlook

Overview

The report finds that shipping's well-to-wake emissions reached 121 percent of the 2008 baseline in 2024 despite efficiency gains. It highlights rapid uptake of energy-efficiency technologies, with over 10,360 ships representing more than 37 percent of fleet tonnage fitted with EETs by May 2025. LNG remains the pragmatic near-term fuel, while methanol, ammonia, hydrogen, onboard carbon capture and nuclear propulsion are presented as transition pathways with infrastructure, safety and cost constraints. The report also emphasizes that only 5 percent of global ports had active alternative-fuel bunkering as of 2024, underscoring the infrastructure gap.
