Are Cruises Sustainable? Eco-Conscious Ways to Travel By Sea

*Collaborative Post

When it comes to planning a holiday, I always try to think about the impact it might have on the environment. Travel is such a wonderful way to explore the world and spend time as a family, but it’s also no secret that it comes with a carbon footprint. Cruises are often seen as one of the less sustainable options, but the industry has been changing a lot in recent years. If you’ve ever wondered whether it’s possible to enjoy a cruise while still being eco-conscious, the answer is yes – with a little awareness and the right choices.

Do cruises really have a bad name?

Cruises have historically had a bad reputation when it comes to sustainability. Concerns about emissions, waste, and energy use at sea are valid and have been talked about widely. But what’s important to know is that many cruise lines have been investing heavily in greener technologies and practices to address these challenges.

From new fuel-efficient ships to improved recycling systems and partnerships with conservation projects, cruising today is a very different picture compared to a decade ago. It’s not perfect (no form of travel really is), but it’s heading in a much better direction.

What’s changing at sea

One of the most promising changes is the introduction of liquefied natural gas (LNG) as a cleaner fuel option. This dramatically reduces sulphur emissions and helps ships run more efficiently. Many modern ships are also being built with advanced waste management systems, onboard recycling, and even water treatment plants that reduce the impact on marine environments.

Some cruise lines are working towards using shore power when docked, meaning they can plug into local electricity rather than running engines in port. This is such a positive step because it reduces pollution in coastal areas where communities are most affected.

Little things you can do as a passenger

As travellers, we have a role to play too. Choosing a newer, more energy-efficient ship is a good start, as these tend to use the latest sustainable technologies. You can also make eco-conscious choices during your trip:

• Pack sustainably: Bring reusable water bottles, straws, and shopping bags to avoid single-use plastics.
  
• Pick the right excursions: Opt for tours that support local communities and avoid activities that exploit wildlife.
  
• Save energy onboard: Simple steps like switching off lights and reusing towels help reduce the overall footprint.
  
• Travel slower: Itineraries with fewer ports and longer stays can be better for the environment and give you a richer experience.
  

Talking about it with the kids

Family holidays are all about creating memories, and cruising can still provide this while being mindful of our choices. Kids can learn so much from seeing the world, but it’s also a brilliant opportunity to talk about looking after it too. Noticing recycling stations onboard, seeing how ships manage resources, and discussing why we bring our reusable bottles can all be gentle ways to raise eco-awareness as a family.

Where to start if you fancy it

If you’d like to look at the possibilities for yourself, the latest cruise deals are a good starting point. Many options now highlight eco-conscious ships and itineraries, so it’s easier to make informed decisions. Odysia brings together a wide range of packages, so you can compare and find something that works both for your holiday plans and your values.

Final thoughts on greener cruising

No holiday is ever going to be 100% sustainable, but what we can do is make more thoughtful choices. Cruises are evolving, and with new technologies and greener practices being introduced, they can be enjoyed in a more eco-conscious way than ever before. By supporting companies that are investing in sustainability and by making small changes ourselves, we can still embrace the joy of travel while caring for the planet at the same time.
