Carbon Footprint of a Winter Holiday

Carbon footprint of a winter holiday: what it costs the climate

A week in the Alps, a city break over Christmas, a long-haul escape to winter sun — these trips feel restorative, but they also generate a significant volume of greenhouse-gas emissions. Understanding the carbon footprint of a winter holiday is the first step toward making more informed choices, whether that means changing how you travel, where you stay, or what you do when you arrive.

This article walks through every major emissions source in a typical winter trip, puts them in perspective, and offers concrete ways to reduce them. Reducing emissions comes first; for what genuinely remains, we explain how verified carbon credits work.

Why winter holidays tend to have a higher footprint

Several features of winter travel push emissions higher than a comparable summer trip might. Heating is the most obvious: hotels, chalets and apartments consume far more energy to stay warm in January than in July, and in many European mountain regions that energy still comes partly from fossil fuels.

Cold-weather activities add another layer. Ski resorts operate energy-intensive lifts, snowmaking equipment and grooming vehicles. Research published in Nature Climate Change in 2023 found that natural snow conditions at many European resorts are already unreliable, which means resorts rely increasingly on artificial snowmaking — a process that can use large amounts of electricity and water. The carbon intensity of that electricity depends heavily on the local grid.

And then there is the journey itself. Many popular winter destinations — ski resorts, winter-sun islands, Christmas-market cities — are reached by air, which is almost always the single largest contributor to the carbon footprint of a winter holiday.

Breaking down the carbon footprint of a winter holiday

Flights: by far the biggest slice

Aviation is typically responsible for the majority of a holiday's total emissions. A return economy-class flight from London to Geneva — a classic ski-holiday route — produces roughly 200–250 kg of CO₂e per passenger according to emission factor estimates used by calculators aligned with the European Union Aviation Safety Agency's annual aviation environmental report. Long-haul winter-sun destinations multiply that figure several times over.

Flying in business class roughly doubles the per-passenger footprint because each seat takes up more floor space, which means more fuel per person. A window or middle seat in economy is, from a climate perspective, a meaningful choice.

Contrails also matter. At cruise altitude, aircraft produce water vapour trails that trap heat in the atmosphere. Scientists estimate this non-CO₂ warming effect could be roughly as large as the CO₂ effect itself over short time horizons, though the science is still developing. Our travel emissions calculator can help you estimate the flight portion of your trip.

Ground transport to and from the resort

Getting from the airport or railway station to a mountain resort often involves a coach transfer, a rental car, or a taxi. A diesel minibus shared among eight people produces far fewer emissions per person than a petrol hire car driven by two. If you are travelling to a destination served by train, the difference can be dramatic: the rail journey from Paris to the French Alps, for example, produces a small fraction of the emissions of an equivalent flight.

Accommodation and heating

A large chalet heated by an oil boiler for a week produces substantially more emissions than a small hotel room in a building connected to a district heating network or served by a heat pump. When comparing accommodation options, look for properties that disclose their energy source. Certification schemes such as the EU Ecolabel or national equivalents can signal lower-impact operations, though they are not universal across mountain destinations.

Skiing, snowboarding and other activities

A ski-lift pass grants access to infrastructure that runs continuously throughout the day. The carbon intensity of ski lifts depends almost entirely on the local electricity grid. Resorts in countries with high renewable shares — such as Norway or Austria — produce far lower emissions per lift ride than those in regions still reliant on coal or gas. Some resorts publish their own sustainability data; it is worth checking before you book.

Snowmaking is a growing concern. As natural snowfall declines at lower altitudes, resorts pump water uphill and freeze it artificially. This process is energy-hungry and the emissions it generates are effectively shared across all skiers using that snow.

Food and drink

Mountain restaurants and resort hotels often import food from far away, and winter menus tend to be meat-heavy. Beef and lamb carry the highest emissions of any food category — typically an order of magnitude more per kilogram than pulses or vegetables. Choosing locally sourced, plant-forward meals while on holiday is a small but genuine emissions reduction, and it is often the cheaper option too.

How a winter holiday compares to everyday life

To put holiday emissions in context: the average EU resident produces around 7–8 tonnes of CO₂e per year across all activities, according to Eurostat greenhouse gas statistics published in 2023. A single return long-haul flight for a winter-sun holiday can add 2–3 tonnes on top of that figure — a substantial fraction of an annual budget, compressed into one week.

That does not mean winter holidays are inherently incompatible with lower-carbon living. It means the choices you make matter more in a concentrated period than they might at home, because the stakes are higher per day.

Practical ways to reduce your winter holiday emissions

• Travel by train where feasible. The Eurostar and Thalys networks connect many Northern European cities to Alpine resorts with dramatically lower emissions than flying. The overnight train from Amsterdam or Brussels to the Alps cuts the travel footprint by an order of magnitude on that leg alone.
• Choose a closer destination. A ski resort in the Pyrenees or the Austrian Tirol produces far fewer transport emissions for a UK or German traveller than one in Japan or Canada.
• Stay longer, travel less. The journey is the biggest emission source. Spending two weeks instead of one at the same destination halves the transport emissions per day of holiday.
• Pick accommodation with renewable energy. Ask the property whether it uses green electricity or district heat. Mountain regions in Scandinavia and parts of the Alps already run largely on renewables.
• Eat lower on the food chain. One plant-based meal per day over a week adds up. Many Alpine restaurants now offer excellent local vegetable and cheese dishes alongside the traditional meat-heavy menus.
• Use shared transfers. A shared coach from the airport generates a fraction of the per-person emissions of a private taxi or rental car.
• Consider a city-break alternative. A few days in a European city — accessed by train — can scratch the winter-holiday itch with a much smaller footprint than a fly-drive ski trip.

What to do about emissions you cannot avoid

Some emissions are genuinely difficult to avoid — for example, if you have family abroad and flying is the only realistic option, or if a ski trip is a once-a-year commitment you are not willing to give up. In those cases, funding verified carbon projects is one way to take responsibility for what remains after you have reduced what you can.

It is important to be clear about what this does and does not do. Purchasing carbon credits does not erase or cancel your travel emissions. What it does is fund projects — forest protection, clean cookstoves, methane capture, carbon removal — that either prevent emissions elsewhere or actively pull CO₂ from the atmosphere. Each credit represents one tonne of CO₂e verified and retired by a recognised standard.

Coffset's impact portfolio spans 22 projects organised according to the Oxford Principles for Net Zero Aligned Carbon Offsetting, certified under standards including Verra's Verified Carbon Standard, Gold Standard, Climate Action Reserve and Puro.earth. Credits are retired through CNaught, and every purchase comes with a certificate. You can read more about what happens to your money on the how we choose projects page.
