Cruise Ship Emissions Ranking

By September 25, 2015 Article, Marine News, Technology No Comments

A long-running environmental organization ranks upcoming cruise ship new builds based on planned emission abatement technologies… and takes some heat from the cruise industry for the results.

Nature and Biodiversity Conservation Union (“NABU”), having been founded in 1899, is one of Germany’s oldest environmental associations. With 560,000 members and sponsors, it is also one of the largest. Their objectives include conservation of habitats and biodiversity, and to promote sustainable practices and climate protection.

One of the issues capturing the long-running organization’s watchful eye is the Cruise Industry’s Impact on the Environment. Particularly, they are concerned that though cruise ships are generally becoming “cleaner,” it is still not doing enough to employ emission abasement technologies and measures. The organization recently released 2015 Rankings on planned new builds to the year 2020, looking at European market developments, environmental ship performance, fuel, and emission abatement measures to be used.

NABU welcomed top-ranked AIDA and Costa Cruises’ recent announcements on managing emissions from their new ships, while they noted the criticisms faced by major players Royal Caribbean and MSC from environmental experts. NABU CEO Leif Miller described the cruise industry as being “at a crossroads,” where companies that do not want to invest in emission abatement and better fuels as acting “negligently.”

Cruise Lines International Association (“CLIA”), however, had criticisms of its own for NABU’s 2015 Cruise Ranking as well as the organization’s air quality measurements taken last year, which they found to be “short of fair and scientifically objective assessments.”

CLIA was quick to point out the cruise industry’s willingness to engage in constructive discourse with environmental groups; how they prioritize stewardship and sustainability as being both “the right thing to do” and as being important to preserve the destinations they visit to keep their industry viable; and how they account for “less than one half of one percent” share of ships to the global shipping fleet – even as they lead the maritime community in technologies and practices for environmental protection.

They may disagree with parameters, methodology and results, but NABU and CLIA, like a majority of the maritime community, all have their reasons for environmental conservation and promoting sustainable and responsible practices. We too, at Kemplon Engineering, hope that the future would soon see wonderful applications of technology and practices that would preserve the environment we all need for our livelihoods and our survival.
