Climate change could cost Swiss winter tourism CHF2 billion annually

Climate change could cause more than CHF2 billion in annual damage to Swiss winter tourism by 2060, according to a federal study reported by SRF.

The study examined three scenarios: one in which countries pursue strong climate action, one with moderate measures and one in which temperatures rise almost unchecked. It assessed five climate risks: heat stress and drought, a rising snow line, heavy precipitation, storms and hail.

The researchers did not model how different risks might compound, said Raphael Bucher, head of climate policy at Switzerland’s Federal Office for the Environment. As a result, the total costs of climate change in Switzerland are likely to be considerably higher than the study’s estimates suggest.

For winter tourism, the study projects annual damage of more than CHF2 billion by 2060. Ski areas below 1,500 to 1,800 metres are expected eventually to close because of a lack of snow, even under the most favourable climate scenario. Higher-altitude resorts could take in displaced skiers, but adapting would be costly. Measures could include stabilising mountain lift stations and operating additional snowmaking equipment.

Agriculture could limit economic losses if enough is invested in irrigation and sufficient water is available, Bucher said. The study also projects a slight increase in hydropower production overall. Drought periods are expected to become more common in summer, while winters are likely to bring less snow and more rain. Hydropower plants will need to invest in managing heavy rainfall.

The study identifies where climate adaptation could reduce costs and where it may not be worthwhile, including at lower-altitude ski resorts.
