Carnival Corporation’s carbon reduction claims come with an important caveat: the figures are based on the number of people the ships can host (not the number of passengers, as most ships are not booked to full capacity in every room) – called available lower berth or ALB. That means the more they expand their fleet, the more climate-damaging emissions they pump into the atmosphere while still reporting that the amount per person decreases.
It looks good on paper and is virtually meaningless for the climate.
Carnival decreasing the amount of climate pollution per person capacity, but increasing their size and emissions overall doesn’t address the growing climate footprint of this company. This is why climate agreements are based on absolute reduction targets, not intensity reductions like Carnival’s current goals.
According to Carnival’s own data, their actual overall emissions have steadily increased for over a decade.
