Cleaner and greener cruises

With pressure mounting for net-zero carbon cruising by 2050, cruise lines are making waves when it comes to sustainable sailings, says Lauren Jarvis

It’s vegetarian night on the MS Fridtjof Nansen, and even the most carnivorous of passengers are enjoying the sustainably sourced menu being served during my epic 27-day voyage through the Arctic’s infamous Northwest Passage with HX (formerly Hurtigruten Expeditions).

In this climatically harsh but environmentally fragile part of the world, our footprint matters more than ever: the Arctic is warming almost four times faster than the rest of the planet.

On my summer cruise from Iceland to Alaska, ice is conspicuously, and worryingly, absent, bar the odd iceberg floating by like a glistening ghost ship, as we spot polar bears, belugas and narwhals from the deck.

HX is leading the way in sustainable cruising, with two hybrid electric-powered lower-emission expedition vessels, the MS Roald Amundsen, which launched in 2019, and the Nansen in 2020. Both transport up to 530 passengers in style through some of Earth’s remotest regions. Onboard, single-use plastic is out, sustainable menus are in, and researchers record wildlife sightings at sea, while guests become citizen scientists and much-needed ambassadors for this precious, magical realm.

Sustainable solutions

This year’s launch of Royal Caribbean’s behemoth, Icon of the Seas – the largest cruise vessel ever to set sail – has once again put the environmental impact of cruising in the spotlight, from the emissions expelled by gargantuan fuel-guzzling ships to the chaotic deluge of passengers flooding into destinations when these floating amusement parks pull into port.

While many companies with larger ships, including Virgin Voyages, are embracing cleaner fuels, reducing waste and ditching plastics, the expedition cruise market is making great strides in sustainability, with companies such as HX, Ponant, Viking, AE Expeditions and Quark Expeditions investing in sustainable strategies and creating itineraries which positively contribute to scientific research, conservation and giving back to local communities.

“Cruising is a carbon-intensive industry, there is no getting away from that,” admits Tudor Morgan, HX’s VP of Sustainability & Industry Relations. “HX was the first cruise line to ban heavy fuel oil (in 2009) and campaigns for its worldwide ban. To set a new standard, we are also considering a range of new, green fuel options, including biofuels made from organic waste.

“Regulation will change emissions in the medium-to-long term, but in the short term, expedition operators are responding more quickly, as the effects on the areas where we sail are very apparent and our guests are often more informed about the climate crisis and want to make a difference. Our goal is to be emission-free by 2050.”

HX offers an immersive but respectful deep-dive into the regions its ships visit, leaving guests with a good understanding of the environmental challenges and threats to local people and biodiversity, while encouraging them to participate in research and science programmes onboard.

“Every journey should have a sense of purpose and meaning,” says Morgan.

“Travellers should be adding value to and getting insight into the destination, so they come away with a changed perspective and potential change in behaviour.

“During a HX sailing, we invite guests to participate in citizen projects, from monitoring whale migration to recording cloud patterns for NASA, and join excursions which encourage a greater appreciation for the environment and habitats we explore.”

Ponant, the first cruise company to be certified as a B Corporation Company, is also innovating, investing in shore-side power connection systems and aiming for its entire fleet of 13 small ships to be equipped with these by the end of 2026.

“We have a goal of cutting our CO2-per-sailing-day emissions by 30% by 2030 and becoming carbon neutral by 2040,” explains Ponant’s General Secretary, Patrick Augier.

Meanwhile, AE Expeditions, which has recently become a B Corporation Company, is now collaborating with Eyesea, a marine pollution mapping organisation, utilising the company’s citizen science programme to get guests involved in protecting the ocean. The company has also announced a sustainable food programme for its Antarctic cruises.

“Many of our members have already announced ambitious Environmental Social & Governance (ESG) plans, which go above and beyond UN goals to outline ESG reporting; building net zero ships; investing in alternative fuels; driving energy efficiency and reducing environmental impacts,” says Akvile Marozaite, CEO of Expedition Cruise Network (ECN) which has more than 20 expedition cruise operator members.

As HX’s Chief Scientist, Dr Meraldi, says: “We have a responsibility to safeguard the places we explore. Beyond minimising our footprint, it is our duty to leave these places better than we found them.”
