The Ethics of Visiting the Ends of the Earth

The camp sits at the foot of a rust-red ridge overlooking Disko Bay. Tents, poles driven into permafrost. Below, a flotilla of zodiac inflatables from three expedition ships bobs in water that would have been iced over a decade ago. The scene is, depending on your vantage point, either the fulfilment of a lifelong dream or a precise illustration of modernity’s appetite for consuming the things it claims to love. Greenland received more than 131,000 visitors in 2023 — a 46% increase in just five years. More airports are coming. More tents, more zodiacs, more boots on permafrost that was never meant to bear them.

A Boom Built on Melting Ice

The numbers are arresting enough to warrant a pause. More than 120,000 people visited Antarctica in the 2023–24 season, compared with 6,400 over the winter of 1991–92 — a near-twentyfold increase in three decades. The global polar travel market was valued at roughly $954 million in 2023 and is projected to reach $2.3 billion by 2032, growing at a compound annual rate of over 10%. The Arctic has absorbed comparable pressure: the number of visitors to land north of the Arctic Circle may have exceeded 10 million in 2024, while Alaska alone received 3 million tourists in the 2023–24 season, 20% higher than the pre-pandemic peak.

What’s driving the surge is, in part, what’s supposed to warn us off. As sea ice retreats and navigation windows lengthen, routes previously impassable are now accessible for eight months of the year. The term coined by researchers — “last-chance tourism” — captures the paradox perfectly: tourists are travelling to witness the consequences of climate change, using the very modes of transport that accelerate it, to see glaciers that may not exist for their children to visit. This is not hypocrisy, exactly. It’s something thornier: a genuine collision between human curiosity and planetary limits.

1 — The Carbon Cost of Responsible Polar Tourism

Responsible polar tourism begins with an honest reckoning with what getting there actually means.

Average per-passenger CO₂ emissions for an Antarctic vacation are 4.14 tonnes — roughly equivalent to the annual carbon output of the average person in several developing nations. A study published in the Journal of Sustainable Tourism in August 2025 found that emissions from onboard services — the so-called “hotel load” — are higher in Antarctica than anywhere else in the world, due largely to fuel-guzzling heating systems. More broadly, Friends of the Earth estimates that the carbon footprint of a week-long cruise is eight times higher than that of a land-based holiday, with a medium-sized cruise ship carrying between 1,000 and 2,400 passengers generating CO₂ equivalent to 12,000 cars over a similar period. Sierra Club + 2

The vessel itself matters. Smaller, modern expedition ships running hybrid or LNG systems carry a fraction of the footprint of the ocean-going giants. The distance matters, too: the Ross Sea modality — ships that push deep into the continent’s interior — generates the highest per-capita emissions of any Antarctic travel category. Itinerary length is now, effectively, a climate variable.

There is also the question of what ships burn. On July 1, 2024, an international ban on the use of heavy fuel oil in Arctic waters came into effect under IMO resolution MEPC.329(76). It was a significant step. Yet the ban’s provisions allow many vessels to continue burning heavy fuel oil until 2029, and key areas including parts of the North Atlantic and the Barents Sea remain exempt — a loophole the Clean Arctic Alliance and Pacific Environment have spent the better part of two years trying to close. The regulation that was heralded as a turning point is, in practice, a holding position. NatLawReviewMaritime Executive

Black carbon compounds the damage. When soot from ship exhausts settles on snow and ice, it reduces albedo — the reflectivity of the surface — and accelerates melting. Despite technical assessments and calls for voluntary measures, black carbon emissions from Arctic shipping continue to grow unchecked, leaving policymakers ill-equipped to protect fragile ecosystems and indigenous livelihoods. A mandatory emissions framework, not an opt-in one, is what the science demands. Brookes Bell

2 — What Ethical Travel to These Places Actually Looks Like

The case against any polar tourism is coherent and its proponents are not cranks. But it rests on a premise that is increasingly difficult to defend empirically: that absence is the only form of protection.

The more defensible position — and the one gradually gaining institutional traction — is that the how of polar travel determines its net effect on these environments as much as the fact of going at all. The number of passengers on expedition cruises rose by 22% from 2023 to 2024. That growth is coming regardless of the ethical debate. The operative question is whether it arrives with regulation, small-ship culture, and genuine conservation investment — or without them. National Geographic

How can tourists minimise their environmental impact in the Arctic or Antarctica? Choose operators with IAATO membership, independently certified carbon-neutral status, or B Corp accreditation. Opt for vessels carrying fewer than 200 passengers, which are bound by stricter shore-landing rules. Support local economies directly by booking Inuit-led excursions, buying crafts from local communities, and eating at local establishments. Avoid itineraries that push deep into pristine interior zones.

Transport choices carry the most weight. Flying to a departure port rather than taking a repositioning cruise from a distant home city can shave a tonne or more off per-trip emissions. Some expedition lines, including Aurora Expeditions, have achieved third-party climate-neutral certification by measuring and offsetting emissions annually under a reduction plan aligned with Science Based Targets. That standard isn’t universal, and greenwashing is rife in adventure travel marketing — but it does set a verifiable floor. Mundy Adventures

The food question is less intuitive. In both Greenland and the Canadian Arctic, local subsistence practices — harvesting seal, walrus, caribou — carry a fraction of the food-miles attached to imported alternatives. Purchasing Inuit crafts and taking tours with local guides contributes directly to local income and livelihoods, helping communities remain in remote areas rather than migrating to cities, where their connection to traditional land stewardship dissipates. The whale meat served on Svalbard is a harder ethical call; marine conservationists are broadly opposed, and demand from tourists risks distorting subsistence quotas into something closer to commerce.

3 — The Second-Order Consequences No One Is Counting

Beyond the carbon ledger, polar tourism carries ecological costs that are slower to register and harder to regulate.

In areas visited most frequently by tourists, snow carries a higher concentration of black carbon from ship exhaust, which absorbs more heat and accelerates snowmelt. Ship traffic also risks introducing invasive species — hitchhiking microbes, seeds, and organisms on boots and clothing — into the Southern Ocean’s vulnerable marine ecosystems. As ice melt creates new patches of bare earth, the pathways for biological contamination multiply. The IAATO’s requirement that visitors decontaminate footwear between landings is sound in principle; its enforcement, at scale, is another matter. The Conversation

There is also the cultural dimension, which tends to get eclipsed by the ecological one. In the Canadian Arctic, the growth of expedition cruising is resulting in negative cultural impacts: the sale of marine mammal parts as souvenirs, increased waste in local communities, and commercial pressure on indigenous hunting traditions. Tourism, when it arrives faster than governance can manage it, tends to extract cultural capital from communities that were never consulted about its arrival. ScienceDirect

The governance architecture is itself a problem. Antarctica is regulated through the Antarctic Treaty System and the IAATO’s self-regulatory framework — a patchwork that works reasonably well precisely because the continent has no resident population and a relatively small number of access points. The Arctic, by contrast, is fragmented across multiple sovereign jurisdictions, each individually responsible for managing both environmental and social impacts on local and indigenous communities. Norway, Canada, Denmark/Greenland, Russia, and the United States have vastly different regulatory appetites. The result is a mosaic of rules that determined operators can navigate by shifting itineraries across borders. Frontiersin

The downstream effect of this governance gap is already visible. In 2023, foreign tourism directly supported 1,075 jobs in Greenland — an increasingly significant share of an economy that has limited alternatives. But tourism-driven development is also funding new airports. Nuuk’s international airport opened in 2024; two more are planned by 2026. Each runway extension makes the next wave of visitors cheaper to transport in and harder to deter. The arctic review

4 — The Case for Going Anyway

Steel-man the opposing view, and it’s more compelling than the industry’s talking points usually acknowledge.

The argument isn’t simply that tourism dollars fund conservation — though they do. It runs deeper. The industry’s narrative that polar tourists become ambassadors, stewards, and advocates for conservation has attracted significant academic scrutiny, with researchers questioning whether such engagement is substantive or largely symbolic. That scrutiny is warranted. A zodiac ride past a calving glacier doesn’t automatically make someone a conservation activist. frontiersin

Still, the empirical record on absence as a strategy is thin. Antarctica’s remarkable preservation owes more to the Antarctic Treaty’s prohibition on extractive industries than to any tourism moratorium — and the tourism that does occur takes place under arguably tighter constraints than almost any other travel on Earth. The 500-passenger limit on ships, the prohibition on landing in most of the continent, the mandatory wildlife distancing rules: these aren’t marketing promises. They’re codified norms with real enforcement histories.

What the critics are right about is the trajectory, not the present state. At 120,000 visitors, Antarctica’s tourism footprint is manageable. At 300,000 — which current growth rates would reach by the early 2030s — it will not be. The question the industry has so far avoided answering honestly is what a carrying-capacity ceiling looks like, and who gets to set it. Self-regulation has brought polar tourism to a better place than most comparable industries. It’s unlikely to be sufficient for what’s coming.

The Irreducible Tension

There is no clean resolution to the ethics of visiting the ends of the Earth. The carbon cost is real and significant. The cultural disruption to Arctic communities is real and undervalued. The invasive species risk is real and underregulated. These are not hypothetical concerns that responsible operators have made obsolete.

What is also true: people are going. The airports are being built. The ships are being ordered. Winter tourism in the Arctic increased by over 600% between 2006 and 2016, and there is no credible mechanism by which that demand simply reverses. In that context, the ethics aren’t really a question of whether polar tourism should exist. They’re a question of what kind of industry it becomes — and whether the people choosing to go are willing to impose meaningful costs on themselves, rather than on the ice. Wellbeingintl

The tent in Disko Bay doesn’t have to be a symbol of everything going wrong. But it won’t be a symbol of anything going right until the person inside it has done the work before booking.
