Carnival Corporation’s cruise ships emit more toxic sulfur oxides than all 291 million cars in Europe combined, according to a study by Transport and Environment (T&E). The particles can cause asthma and acid rain, among other environmental issues. The study found that the 63 cruise ships operated by Carnival Corporation alone emit 43% more sulfur oxides than all the cars in Europe. While the numbers are concerning, there are signs of improvement. The International Maritime Organization’s (IMO) regulation from 2020, which mandates a reduction in the allowable sulfur content in ship fuel from 3.5% to 0.5%, has led to a significant decrease in emissions from the company’s fleet.
However, the overall emissions from the cruise industry have increased due to the growing number of ships on the seas. T&E also noted that cruise ships are spending more time in European ports, consuming more fuel. Carnival Corporation has set ambitious goals to reduce its carbon emissions by 40% compared to 2008 levels by 2030 and achieve carbon-free operations by 2050. The company’s representative stated that they are the only major cruise operator that emits fewer greenhouse gases today than in 2011, despite a projected growth of 30%. The company has also invested in technology for shore power connections, reducing fuel consumption and carbon intensity per cabin by 15% since 2019.
The cruise industry’s impact on the environment has been a growing concern in recent years, and this study highlights the need for continued efforts to reduce emissions. While the IMO’s regulation is a step in the right direction, more needs to be done to ensure that the industry is sustainable and environmentally responsible. As consumers, we can also play a role by choosing eco-friendly cruise options and supporting companies that prioritize sustainability.
