What Is the Most Sustainable Way to Travel? 5 Common Travel Dilemmas Explored

Last week, I explored several everyday eco dilemmas that challenged some of my assumptions about sustainable living.

Travel, it turns out, is no different.

I keep waiting for sustainable travel to become simpler.

It never does.

The more I read, compare, calculate, and research, the more I find myself staring at choices where the greener option is surprisingly difficult to identify.

Cruises versus flights.

RVs versus hotels.

Eco-resorts versus local guesthouses.

What initially seem like straightforward sustainability decisions often reveal layers of hidden trade-offs.

Here are a few travel dilemmas I have found myself wrestling with over the years as I have tried to travel more consciously.

1. Cruise vs Flying

For a long time, I assumed that flying automatically carried a higher environmental footprint than cruising. But the reality turned out to be more complicated.

According to the International Council on Clean Transportation, cruise ships produce higher emissions per passenger than flying, especially when additional pollutants beyond carbon dioxide are taken into account. Yet aviation remains highly carbon-intensive too, particularly for long-haul trips and frequent travel.

Cruises combine transportation, accommodation, food, and entertainment in one place, which can reduce the need for additional hotels or flights between destinations. They also allow slower movement between multiple locations. At the same time, cruise ships consume enormous amounts of fuel and energy, and their environmental impact varies significantly depending on the ship, itinerary, and passenger behavior.

This became a very real dilemma for me when planning a Caribbean trip with my son. I remember sitting in front of my laptop with two tabs open. One showed flights hopping between islands. The other showed a cruise itinerary tracing almost the same route.

The cruise felt easier. Cheaper. Simpler.

And yet every article I opened seemed to accuse me of making the wrong choice. Never mind that the cruise would replace multiple flights and hotel stays. The message often felt clear: cruises were the more unsustainable option

The longer I think about sustainable travel, the more I realize how rarely these choices fit neatly into “good” or “bad” categories.

These days, when planning trips, I mostly ask AI to help estimate the footprint of different travel options. Not because I believe travel can become perfectly sustainable, but because I still want environmental impact to remain part of the conversation alongside safety, cost, and practicality.

2. Camping Car vs Car and Accommodation

This is another travel dilemma that initially seemed much simpler than it turned out to be.

For a long time, I actually assumed RV travel must automatically be the greener option. One vehicle replacing flights, hotels, restaurants, and repeated laundry cycles felt intuitively more sustainable to me. There was also something appealing about carrying your small living space with you through nature instead of depending on large hotel infrastructures.

What surprised me was not that RVs consume fuel. I knew that already.

What surprised me was how difficult it became to compare one visible source of emissions against dozens of hidden ones.

Camping cars consume large amounts of fuel, especially over long distances. Yet hotels also consume enormous amounts of energy and water through heating, air conditioning, laundry, pools, cleaning, and food waste.

Suddenly the comparison no longer felt straightforward.

We experienced this dilemma ourselves. When traveling to Las Vegas and the Grand Canyon, we chose a car and accommodation. But when exploring Yellowstone and the American Northwest as a family of six, we opted for an RV instead.

Looking back, I am still not entirely sure which choice carried the smaller footprint.

A smaller car combined with simple accommodation may often produce a lower footprint than driving a large camping car long distances. At the same time, for larger families sharing one vehicle, cooking meals themselves, avoiding flights, and staying longer in one place, the overall comparison becomes much less clear.

Neither choice was entirely environmentally pure. Both reflected different trade-offs within different journeys.

3. Carry-On Only vs Checked Luggage

I once assumed this was one of the simplest sustainability questions in travel.

Less luggage means lighter aircraft, and lighter aircraft generally mean lower fuel consumption.

But even here, the reality becomes more layered.

Ultralight travel can sometimes encourage disposability through miniature toiletries, excessive packaging, or repeatedly buying small travel-sized products. I once proudly packed only a carry-on, only to spend the trip repeatedly buying things I had decided were “unnecessary” at home.

Hotel mini bottles and individually packaged convenience items may reduce luggage weight while increasing waste elsewhere.

According to the International Air Transport Association (IATA), aircraft weight does influence fuel consumption and emissions. Yet the environmental impact of travel habits extends far beyond luggage alone.

Our family now mostly tries to travel with carry-on luggage only, especially for shorter trips. The exceptions are longer relocations or situations where checked luggage simply makes more practical sense financially or logistically.

Thankfully, many accommodations increasingly provide refillable soap and shampoo dispensers instead of endless miniature plastic bottles. Small shifts like these remind me how sustainability often evolves through gradual improvements rather than dramatic transformation.

4. Simple Local Hotels vs Vacation Rentals vs Eco-Resorts

This may be one of the travel dilemmas where appearances become particularly misleading.

Eco-resorts often market themselves through sustainability language, yet many involve energy-intensive luxury infrastructure, imported materials, swimming pools, spas, golf courses, and remote construction. Sometimes older local guesthouses may unintentionally consume less simply through simplicity rather than branding.

Meanwhile, all-inclusive resorts centralize transportation and services efficiently, but can also generate enormous food waste, laundry demands, and energy consumption. Vacation rentals may reduce some centralized impacts while simultaneously contributing to housing pressure, inefficient heating and cooling, and overtourism in residential neighborhoods.

During our recent family trip to Vancouver, I searched Booking.com for accommodations with sustainability certifications. There were only a handful available in the neighborhoods where we wanted to stay.

I clicked through them one by one.

They looked beautiful.

They were also far beyond what we could realistically afford as a family of six.

According to the United Nations, tourism sustainability depends not only on individual choices but also on broader infrastructure, local economies, resource use, and community impact.

Yet sitting there in front of my screen, sustainability felt much less like a global principle and much more like a budget line.

The experience left me wondering how often sustainability becomes something people aspire to rather than something they can realistically access.

5. Sustainable Travel Clothes vs Rewearing What We Already Own

Travel increasingly comes with its own shopping culture. Minimalist wardrobes, merino layers, quick-dry clothing, wrinkle-free fabrics, “sustainable” collections — sometimes it feels as though traveling responsibly now requires buying an entirely new version of ourselves first.

And I understand the appeal.

Technical clothing can be lighter, easier to wash, quicker to dry, and practical for long journeys. Materials such as merino wool are often promoted as more sustainable because they can be reworn multiple times before washing.

Yet the dilemma becomes more complicated when sustainability itself begins encouraging additional consumption.

Travel today also unfolds under the invisible pressure of photography. Social media teaches us that every destination deserves a slightly different version of ourselves — different outfits and different aesthetics for different landscapes.

And I understand that temptation too.

For years, I often returned from trips with new local clothes — something embroidered from Central Asia, loose fabrics from Southeast Asia, dresses that somehow felt tied to a place and the version of myself I had briefly become there. Travel can make us want to return not only with memories, but with a revised visual identity.

Yet buying entirely new “sustainable” or destination-specific wardrobes also creates its own environmental footprint through production, transport, packaging, and textile waste.

At the same time, constantly washing a very limited wardrobe while traveling also consumes water and energy.

These days, I try to travel with fewer clothes, rewear more pieces, and resist the feeling that every destination requires a new aesthetic.

I think one facet of sustainable travel for me has been learning to feel comfortable being seen repeatedly in the same clothes — and realizing that most people probably notice far less than we imagine. And when they notice — so what.

The Uneasy Beauty of Traveling Consciously

Travel itself is already a compromise.

Movement leaves traces. Curiosity consumes resources. Even awareness has limits.

And yet I still believe there is value in paying attention. In slowing down where we can. In staying longer if we can. In questioning excess. In resisting mindless consumption disguised as freedom.

Maybe sustainable travel is not about finding one perfectly ethical way to move through the world.

Maybe it is about remaining awake inside the contradictions instead of pretending they do not exist.
