CLIA releases 2020 Environmental Technologies and Practices Report

Annual report affirms cruise industry leadership and progress in maritime environmental protection practices.

ATHENS – Cruise Lines International Association (CLIA), the leading voice of the global cruise industry, released the Global Cruise Industry Environmental Technologies and Practices Report produced by Oxford Economics. The report highlights the progress that CLIA oceangoing cruise line members continue to make towards the development and implementation of advanced technologies and practices to achieve lower emissions, greater efficiencies, and a cleaner environment onboard, at sea and in port.

While cruise ships comprise far less than 1 percent of the global maritime community, the latest report substantiates how cruise lines have taken a leadership role in the adoption of maritime technologies that benefit the entire shipping industry. To date, the cruise industry has invested over $23.5 billion in ships with new technologies and cleaner fuels to reduce air emissions and achieve greater efficiency. This is a $1.5 billion USD increase over the 2019 report findings.

“Even as we have worked to address and overcome the impacts of COVID-19, the cruise industry remains committed to a cleaner, more sustainable future. With over $23 billion invested in ships with new technologies and cleaner fuels, such as exhaust gas cleaning systems and liquified natural gas, I can only imagine what we will accomplish together in the next ten years and beyond,” said Kelly Craighead, president and CEO of Cruise Lines International Association (CLIA). “This report affirms our commitment to environmental sustainability and I commend our members for their continued leadership and demonstration of the highest standards of responsible tourism.”

CLIA cruise lines were the first to publicly commit as a maritime sector, to reduce the rate of carbon emissions by 40% by 2030 compared to 2008. As noted in the report, CLIA oceangoing cruise line members continue to work diligently to achieve ambitious goals like this and meet rising expectations. Substantial progress has been achieved in the following areas:

  • LNG Fuel* – The 2020 report found 49% of new build capacity will rely on LNG fuel for primary propulsion, a 51% increase in overall capacity compared to 2018.
  • Exhaust Gas Cleaning Systems (EGCS)* – More than 69% of global capacity utilizes EGCS to meet or exceed air emissions requirements, representing an increase in capacity of 25% compared to 2018. Additionally, 96% of non-LNG new builds will have EGCS installed, an increase in capacity of 21% compared to 2019.
  • Advanced Wastewater Treatment Systems – 99% of new ships on order are specified to have advanced wastewater treatment systems (bringing global capacity to 78.5%) and currently 70% of the CLIA oceangoing cruise line fleet capacity is served by advanced wastewater treatment systems (an increase of 5% over 2019).
  • Shore-side Power Capability – In port, cruise ships are increasingly equipped with the technology to allow delivery of shoreside electricity, thus allowing engines to be switched off, and there are many collaborations with ports and governments to increase the availability.
    – 75% of the new build capacity is either committed to be fitted with shore-side electricity systems or will be configured to add shore-side power in the future.
    – 32% of global capacity (up 13% since 2019) are fitted to operate on shore-side electricity in the 14 ports worldwide where that capability is provided in at least one berth in the port.

The progress across these multiple areas demonstrate CLIA’s view that it is integral, urgent, and feasible to balance fostering growth with policy and technology changes that help preserve the air and oceans in which the industry operates.

“The cruise industry works every day to advance its responsible tourism efforts and recognizes that continued and greater investment in research is critical to identifying and producing new fuels and propulsion systems,” said Adam Goldstein, Chairman of CLIA Global. “This is why CLIA along with other maritime sector partners have proposed to establish and fund a $5B Research and Development Board dedicated to working collaboratively across the sector to
identify the technologies and energy sources that will provide additional opportunities to lessen our environmental footprint and meet the ambitious goals set by the IMO.”

Maria Deligianni, National Director Eastern Mediterranean at CLIA, presented the key highlights of the report in the Thessaloniki Sustainability Summit “Sustainable Cities and Ports” which was held on 7 September. During the discussion about “sustainable shipping”, Mrs. Deligianni highlighted that: “Despite the challenging times, our commitment to do our part in environmental sustainability remains high in our agenda. Protecting the environment and the destinations we visit is a business imperative”.


* “All CLIA cruise lines members are required to perform to the stringent requirements of Emission Control Areas (ECAs). For ships operating outside ECAs, CLIA cruise lines must meet the new International Maritime Organization (IMO) 2020 Global Sulfur Limit (effective 1 January 2020) for fuel oil used on board ships of 0.50% m/m (mass by mass) through the use of compliant low-sulfur fuels, alternative technologies such as exhaust gas cleaning systems (EGCS), and new ships propelled by liquified natural gas (LNG) fuel.”
