Cruise industry faces ESG pressure over high CO2 emissions

The cruise industry is facing increasing scrutiny regarding its environmental impact and ESG (Environmental, Social, and Governance) commitments. Data from the German Federal Environment Agency indicates that a single seven-day cruise can generate approximately 0.95 tonnes of CO2 equivalents per passenger. This figure accounts for the total climate impact of emitted gases rather than just direct fuel consumption.

A ranking by NABU reveals that progress toward climate targets is stagnating for many operators. While most cruise lines maintain their long-term goals to reach net-zero greenhouse gas emissions, few have met their specific annual targets. Notably, Marella and Hapag-Lloyd Cruises showed a decline in target achievement compared to the previous year.

A significant environmental concern remains the use of heavy fuel oil. Out of twelve investigated cruise lines, only four have transitioned away from this fuel source. Heavy fuel oil, a byproduct containing high levels of sulfur and heavy metals, is significantly more harmful to marine environments and coastal populations than standard automotive fuels.
