90% Artificial: How Italy and Austria Already Ski on Made Snow

Roughly 90% of Italy's ski terrain and 75% of Austria's is covered by snowmaking. Why made snow is now the base, not the backup — and what that implies.

Most skiing in the Alps already happens on snow a machine made. In Italy roughly 90% of ski terrain is covered by snowmaking and in Austria about 75%; across the wider Alpine industry the ski day a visitor experiences is, more often than not, a snowmaking product rather than a natural one. Snowmaking is no longer a supplement for thin years — it is the load-bearing infrastructure the season is built on.

That single fact reframes the whole industry conversation. If the base most people ski on is manufactured, then the efficiency of manufacturing it — the water, the energy, and the temperature window it needs — is not an environmental footnote but the central operating question. This piece sets out how much of the sport already runs on made snow, why the share keeps rising, and what that dependence implies for how snow gets made from here.

Key takeaways

  • Italy covers roughly 90% of its ski terrain with snowmaking; Austria roughly 75% (2024, directional industry figures).
  • Snowmaking has shifted from an insurance policy to primary infrastructure — the base most Alpine skiers use.
  • The 2024-25 season saw a record 399M skier visits worldwide (Vanat report), sustained substantially by made snow.
  • Climate risk drives the share upward: without snowmaking, 53% of 2,234 EU resorts face very high snow-scarcity risk at +2 °C (François et al. 2023).
  • Because so much skiing is manufactured, the efficiency of making snow — water and energy per m³ — becomes the industry's decisive lever.

How much of ski terrain actually uses artificial snow?

A large and rising majority in the core Alpine markets. Industry figures for 2024 put snowmaking coverage at approximately 90% of ski terrain in Italy and around 75% in Austria, with Switzerland, France, and Germany trailing but climbing. These are directional national estimates rather than audited counts, but the direction is unambiguous: in the countries that define European skiing, most pistes can be, and routinely are, covered by machine.

Coverage is not the same as constant use — a resort with 90% snowmakable terrain does not run guns on all of it every day — but it does mean the option to manufacture the season is now near-total in Italy and Austria. Skiers who assume they are on natural snow in December are, in these markets, usually on a manufactured or manufactured-and-topped-up base. The distinction between the two, in density and how they ski, is covered in artificial vs natural snow.

| Country | Approx. snowmaking coverage of terrain | Status | |---|---|---| | Italy | ~90% | Highest in the Alps | | Austria | ~75% | Very high | | Switzerland | ~50%+ | Rising | | France | ~40%+ | Rising | | Germany | Variable, high at major resorts | Rising |

Figures are 2024 directional industry/Statista estimates, not audited national statistics.

Why has snowmaking become the base rather than a backup?

Because natural snow reliability is shrinking exactly where the industry's revenue sits, and snowmaking is the adaptation that keeps resorts viable. The peer-reviewed picture is direct: François et al. (2023, Nature Climate Change) find that 53% of 2,234 European resorts face very high risk of snow scarcity at +2 °C of warming without snowmaking — but with 50% snowmaking coverage that risk falls to 27%. Snowmaking roughly halves the exposure.

The elevation story compounds it. Spandre et al. (2019, The Cryosphere) project that only 14–24 French Alps and Pyrenees resorts remain naturally snow-reliable by 2030–2050, while 83–116 more stay viable only with snowmaking. That is the mechanism turning snowmaking from backup into base: as the natural snow line rises, the manufactured base is what remains. We cover the resort-risk data in full in will ski resorts survive climate change. None of this means resorts "will close" — the research language is snow-scarcity risk, and snowmaking is precisely the lever that manages it.

What does near-total dependence on made snow cost?

Enough that it now dominates operating decisions. Snowmaking is roughly 17% of daily operating expenditure at large Swiss resorts (Vorkauf et al. 2022, Andermatt), and in some North American operations it approaches half the electricity bill. The Austrian sector's own accounting is precise: Aigner, Steiger & Mayer (2026) put national snowmaking at 281 GWh per season (0.46% of Austria's electricity), about 51 million m³ of water, ~2,900 m³ per hectare, and ~130 g CO₂ per skier visit.

Two implications follow from those numbers:

  • The cost is concentrated early. Building the base before the holidays is the most energy-intensive stretch of the season, which is why missing an early opening is so damaging — see what missing Christmas costs a ski resort.
  • The footprint scales with dependence. As coverage rises toward the Italian 90% norm, water and energy per season rise with it. That is the environmental critique of snowmaking, and it is a fair one on current technology.

We break the cost structure down in the 17% line item and the energy half in how much electricity snowmaking uses.

Is the made-snow share still rising — and where?

Yes, and fastest outside the already-saturated Italian and Austrian markets. Italy near 90% has little coverage left to add; the growth is in Switzerland and France, where coverage is lower but climbing as lower-elevation resorts respond to the same reliability pressure, and in newer ski economies building infrastructure from scratch.

The demand driver is structural rather than cyclical. Spandre et al. (2019, Scientific Reports), analysing 129 resorts covering 96% of French Alpine lift infrastructure, project snow-season losses of around 44% at 1,500 m versus about 11% at 3,000 m under +0.9–2.3 °C of warming — and model snowmaking water demand rising from roughly 13 to as much as 54 million m³ as resorts compensate. In other words, the resorts with the most to lose from warming are precisely the ones adding the most snowmaking, so coverage and dependence climb together at exactly the elevations where the margin is thinnest.

That is the uncomfortable feedback the industry sits inside: warming reduces natural snow, resorts add snowmaking to compensate, and snowmaking's own water and energy demand rises with the warming that prompted it. It is why efficiency per m³ is not a nice-to-have but the term that decides whether the compensation stays affordable. Some of that pressure is met by shifting guns to run in the narrow cold windows the season still offers — the season-extension logic in extend your ski season — but the deeper answer is making each m³ cost less to produce.

If skiing runs on made snow, what is the decisive lever?

Efficiency per cubic metre of snow — the water and energy it takes to make it, and the temperature window in which it can be made. When most of the season is manufactured, marginal gains in how snow is made compound across the whole operation, whereas debates about whether to make snow are largely settled by the coverage figures above.

Most of the efficiency conversation focuses on four levers: renewable power, water reclamation, automation, and demand reduction. There is a fifth that the standard toolkit omits — additive chemistry that reduces the water and energy needed per m³ of snow, and widens the temperature window in which snow can be made at all. We make the full argument in chemistry as the missing fifth lever. For an industry that already skis mostly on made snow, a modelled +3 °C wet-bulb advantage and 300–500 extra snowmaking hours per season is not a marginal convenience; it is a direct lever on the largest early-season cost and the reliability the whole business now depends on.

The honest framing

Two things are true at once. Snowmaking is what keeps Alpine skiing operating as natural reliability declines — the François and Spandre data make that case cleanly. And snowmaking's water and energy footprint is real and rises with coverage — the Aigner and Andermatt data make that case just as cleanly. The resolution is not to make less snow, which the coverage figures show is not on the table, but to make each cubic metre of it with less water and energy. That is the whole point of treating efficiency, including chemistry, as the industry's central question rather than a side one.
