Sustainable bookings have placed Switzerland alongside Italy, Germany, Spain and France at the forefront of a major transformation in Europe’s summer travel market, as Interhome has recorded powerful growth in eco-conscious holiday-home reservations. Between 2020 and 2025, bookings for qualifying sustainable properties across these five markets more than doubled, while their share of total summer reservations increased from 16.7 per cent to 29.5 per cent. Italy led the five countries with a 40.1 per cent share, followed by Germany, Switzerland, Spain and France. Rising demand for recycling facilities, photovoltaic systems, electric vehicle charging points, efficient heating, low-energy lighting and water-saving equipment has shown how renewable energy features, greener guest choices and continued property investment are reshaping Europe’s summer accommodation market.

Interhome’s Analysis Identifies Changing Booking Behaviour

Summer booking patterns recorded in 2020 and 2025 were compared through Interhome’s Sustainable Summer Booking Trends analysis. Reservations made across Switzerland, Italy, Germany, Spain and France were examined. Rather than every holiday home being automatically classified as environmentally responsible, selected property features were considered.

Renewable energy use, efficient heating, lower-energy lighting, recycling arrangements, water-saving technology and proximity to public transport were included within the sustainability criteria. Photovoltaic installations and electric vehicle charging facilities were also assessed. The reported increase should therefore be understood as growth in reservations for properties displaying recognised sustainability-related characteristics.

Italy Leads While Other Major Markets Advance

Italy was given the strongest position in the five-country analysis after sustainable bookings reached 40.1 per cent of its summer booking mix in 2025. Significant progress was also identified across Germany and Switzerland. Different levels of adoption were observed in Spain and France, although greener accommodation features were increasingly made available in both markets.

Recycling facilities were found among the most widely expanded features. Growth was also identified in electric vehicle charging infrastructure and solar energy installations. These improvements suggested that environmental performance was increasingly being treated as a practical part of holiday-home management rather than as a promotional addition.

Wider Tourism Growth Strengthens the Opportunity

The transformation has been unfolding within a large and expanding European accommodation market. During the first quarter of 2026, 471.1 million nights were recorded in tourist accommodation across the European Union. Year-on-year growth of 3.4 per cent was registered.

The largest absolute increases were recorded in Italy, Spain and Germany. International tourism grew by 5.5 per cent, while domestic tourism expanded by 1.7 per cent. Although these official figures do not measure sustainable bookings, the scale of the market has been demonstrated. Wider adoption of renewable energy, efficient appliances, recycling systems and water-saving equipment could therefore influence millions of future European stays.

Italy Uses Greener Holiday Homes to Strengthen Its Summer Tourism Appeal

Italy was placed at the forefront of the five analysed markets after sustainable bookings represented 40.1 per cent of Interhome’s summer reservations in 2025. The result showed that environmentally equipped holiday homes were being selected by a considerable proportion of travellers. This shift has widened Italy’s accommodation appeal beyond conventional hotels, resorts and villas by making greener independent stays more visible within its tourism market.

Strong growth in properties fitted with solar panels was recorded in Italy. These installations can support the electricity requirements of rural villas, coastal apartments and countryside holiday homes. Their availability may become particularly valuable during the busy summer season, when cooling, refrigeration and other electrical systems are used more intensively. Travellers are also being given greater freedom to combine privacy and self-catering facilities with renewable energy features.

The trend may encourage owners to modernise older properties and compete through environmental performance as well as price, design and location. Small destinations could also benefit when sustainable holiday homes attract visitors beyond major tourism centres. However, the booking data did not measure visitor spending, emissions reductions or the number of new tourists generated. The clearest impact has been seen in accommodation choice, property investment and the growing visibility of greener Italian stays.

Germany’s Strong Domestic Market Creates Wider Demand for Efficient Stays

Germany was ranked second after sustainable bookings accounted for 36.1 per cent of its analysed summer reservations. More than one in three bookings was therefore connected with a property displaying qualifying sustainability features. This result has indicated that greener accommodation is being integrated into ordinary domestic and regional travel decisions rather than being restricted to specialist environmental holidays.

Germany’s extensive domestic tourism market gives the change particular importance. During the first quarter of 2026, 58.5 million domestic guest nights were recorded in German tourist accommodation. When a large domestic market is served by energy-efficient holiday homes, demand can be distributed across countryside destinations, lake districts, coastal regions and smaller towns. Longer road journeys may also be supported more conveniently when electric vehicle charging is offered at or near the accommodation.

Tourism businesses may be encouraged to respond by improving heating systems, lighting, appliances, recycling arrangements and renewable electricity access. These upgrades can strengthen the competitiveness of individual properties while giving booking platforms more clearly differentiated accommodation to promote. The Interhome figures do not establish that sustainability was the only reason behind each reservation, but they show that greener features are now attached to a meaningful share of Germany’s summer holiday-home demand.

Switzerland Connects Alpine Tourism With Greener Mobility

Switzerland followed Germany closely, with sustainable bookings representing 35.9 per cent of Interhome’s analysed summer reservations in 2025. The result placed the country only 0.2 percentage points behind Germany. For Swiss tourism, the trend is especially relevant because holiday homes are widely used in mountain, lake and rural destinations where energy demand and transport access can influence the environmental impact of a stay.

Notable growth was identified in properties offering electric vehicle charging. This infrastructure can make Alpine and countryside holidays easier for travellers arriving in electric cars. Guests can recharge at selected accommodation instead of depending entirely on public charging stations during their journeys. This added convenience may help rural properties remain accessible as road travel gradually becomes more electrified.

Efficient heating and renewable energy are also important within mountain accommodation, where changing temperatures can create energy requirements beyond the winter season. Better-equipped properties can help Swiss destinations combine independent travel with improved resource management. The development may also strengthen year-round tourism by making greener accommodation suitable for hiking holidays, lake trips and nature-based summer stays. Nevertheless, the booking figures do not measure the complete carbon footprint of transport or accommodation use.

Spain Brings Renewable Energy Into Its High-Volume Coastal Market

Spain recorded a 29.3 per cent share of sustainable bookings, placing it close to the five-market average of 29.5 per cent. Almost three in every ten analysed summer reservations were connected with qualifying sustainable holiday homes. This development matters because Spain receives large numbers of international visitors and supports one of Europe’s most extensive coastal accommodation markets.

Strong growth in solar-panel availability was identified among Interhome’s Spanish properties. Solar energy can be particularly useful in destinations where electricity demand rises during hot summer periods. Air conditioning, swimming-pool equipment, lighting and refrigeration can place pressure on property energy use. When renewable electricity and efficient appliances are combined, some of that pressure may be reduced.

Spain recorded 54.1 million international guest nights during the first quarter of 2026, representing about one-quarter of all international nights spent in European Union accommodation during that period. The Interhome share covers only the company’s analysed reservations, but it demonstrates how greener holiday homes are entering a much larger visitor economy. As travellers are given more environmentally equipped choices, coastal and rural destinations may be encouraged to compete through energy efficiency, water conservation and waste management as well as beaches, weather and price.

France Gains an Opportunity to Expand Low-Impact Road Trips

France recorded the lowest share among the five markets, with sustainable bookings representing 16.1 per cent of its analysed summer reservations. The figure shows that greener properties occupied a smaller part of Interhome’s French booking mix than in Italy, Germany, Switzerland or Spain. However, the difference also reveals considerable room for the sustainable accommodation market to expand.

Notable growth in electric vehicle charging facilities was identified in France. This development could support road-based tourism across rural villages, coastal regions and mountain destinations. Travellers using electric vehicles may find independent properties more convenient when overnight charging can be accessed at the accommodation. Lesser-known destinations may also become easier to include within greener road-trip itineraries when dependable charging is provided.

France recorded 46.3 million domestic accommodation nights during the first quarter of 2026. Its large domestic market provides a substantial audience for energy-efficient cottages, apartments and holiday homes. If more sustainability features are installed and displayed clearly during booking, greener stays could be extended across a wider range of French destinations. The impact could be felt through stronger property investment, improved electric mobility and greater competition among accommodation providers.

Different Results Reveal One Shared Tourism Transformation

Different stages of sustainable accommodation development were shown across the five countries. Italy led with 40.1 per cent, followed by Germany at 36.1 per cent, Switzerland at 35.9 per cent, Spain at 29.3 per cent and France at 16.1 per cent. These figures should not be treated as national tourism-wide shares because they were calculated from Interhome’s booking data.

Their significance lies in the direction of travel. Holiday homes are increasingly being compared through renewable energy, charging access, recycling, efficient heating and water-saving features. Tourism destinations are consequently being encouraged to connect environmental performance with visitor comfort and accommodation quality.

The change is affecting how properties are equipped, marketed and selected. Travellers are being offered more practical ways to include sustainability in their holidays, while owners are being given a clearer reason to invest in greener infrastructure. Across Switzerland, Italy, Germany, Spain and France, sustainable bookings are therefore influencing not only reservation shares but also the future design and competitiveness of Europe’s summer tourism market.

Sustainable Features Become Part of Holiday Planning

The growth of sustainable bookings shows that environmental features are increasingly being considered alongside price, location, space and comfort. Travellers are being given more opportunities to select holiday homes with renewable energy, efficient heating, water-saving equipment, recycling facilities and electric vehicle charging. Greener accommodation is therefore being integrated into ordinary summer travel instead of being limited to specialist eco-retreats.

This change is affecting how holidays are planned. Electric vehicle users can look for charging facilities before confirming a stay. Rail travellers can select properties near public transport. Families can identify accommodation with recycling arrangements and efficient appliances. Visitors seeking renewable energy can choose properties fitted with photovoltaic systems.

The trend is also changing how holiday homes are presented online. Environmental features are being displayed as practical amenities rather than vague sustainability claims. This makes comparison easier and allows travellers to understand what is actually provided before making a reservation.

How Country-Level Changes Affect Tourism

Different effects are being created in each market. Italy and Spain can use extensive sunshine to support solar-powered accommodation. Switzerland and France can improve road-trip access by expanding electric vehicle charging. Germany can strengthen its large domestic tourism sector through efficient rural and regional properties.

These changes may also help visitor activity spread beyond major cities and famous resorts. Travellers using holiday homes often stay in residential, rural or coastal communities where conventional hotel supply may be limited. When greener properties are made available in such areas, tourism spending can be distributed among local shops, restaurants, transport providers and visitor attractions.

Greener Properties Can Strengthen Regional Tourism

The growing demand for eco-conscious holiday homes may encourage owners to invest in buildings that were previously marketed mainly through location, size or price. Solar panels, efficient appliances and charging stations can give individual properties an additional competitive feature. Smaller destinations may benefit when their accommodation supply becomes more attractive to environmentally aware visitors.

The following tourism benefits may be supported:

• Wider destination choice: Greener cottages, villas, chalets and apartments can make rural and lesser-known destinations more appealing.
• Stronger road-trip infrastructure: On-site charging can support electric vehicle journeys through Alpine, coastal and countryside regions.
• Improved year-round competitiveness: Efficient heating and insulation can make some properties more practical beyond the peak summer period.
• Greater local spending: Visitors staying outside major resorts may support nearby food businesses, attractions and transport services.
• Clearer accommodation comparison: Verified property features can help travellers compare environmental facilities before booking.
• Encouragement for property upgrades: Booking demand may give owners a stronger commercial reason to install greener technology.

These outcomes should be treated as potential tourism benefits rather than direct results already measured by the Interhome study. The analysis recorded bookings and property features. It did not calculate local spending, length of stay, employment creation or destination-wide emissions.

Environmental Facilities Can Improve the Guest Experience

Sustainable technology does not have to reduce comfort. Efficient heating can maintain a suitable indoor temperature while using less energy. Water-saving fittings can reduce consumption without preventing ordinary use. Solar electricity can support everyday appliances, while on-site vehicle charging can make travel more convenient.

The value of these features is likely to be noticed most when they solve a practical travel need. A charging point can remove uncertainty from an electric road trip. A property near a railway station can reduce the need for car hire. Solar energy and efficient cooling can support summer comfort while limiting reliance on conventional electricity.

What Travellers Can Examine Before Booking

Travellers may be helped by reviewing specific property information instead of relying only on broad environmental descriptions. The following details can be checked:

• Whether renewable electricity is generated or purchased by the property
• Whether an electric vehicle charger is private, shared or located nearby
• Whether public transport can be reached safely on foot
• Whether recycling containers and disposal instructions are provided
• Whether heating, cooling and household appliances are energy efficient
• Whether water-saving taps, showers or toilets have been installed
• Whether sustainability information has been verified through a recognised assessment
• Whether local services and attractions can be accessed without lengthy car journeys

This information can help a traveller decide whether the accommodation matches the intended journey. A property offering several sustainable features may still require a long flight or car journey. The complete environmental effect of a holiday therefore cannot be determined from the accommodation alone.

Sustainable Bookings Push Tourism Beyond Marketing Claims

The increase from 16.7 per cent of Interhome’s summer booking mix in 2020 to 29.5 per cent in 2025 shows that greener properties have gained a larger commercial role. Owners and destination businesses are being shown that environmental facilities can influence how accommodation is compared and selected.

However, credible information will remain essential. Sustainability claims should be linked to identifiable features such as solar generation, efficient heating, charging access or water-saving systems. Clear descriptions can reduce confusion and help travellers avoid properties supported only by broad promotional language.

The impact on European travel is therefore wider than a change in reservation shares. Sustainable bookings are influencing property investment, journey planning, regional accessibility and the way holiday homes are marketed. Across Switzerland, Italy, Germany, Spain and France, greener accommodation is gradually being turned into a practical part of the summer tourism experience.

Accommodation Providers Face Changing Visitor Expectations

The rapid growth of sustainable bookings is creating new expectations across Europe’s holiday-home market. Travellers are increasingly being offered properties where comfort, independence and environmental features are combined. Consequently, accommodation providers may be required to compete through energy efficiency, renewable power and transport accessibility alongside traditional factors such as price, location and space.

Property owners may be encouraged to invest in photovoltaic systems, ecological heating, efficient lighting, water-saving installations and electric vehicle charging. These upgrades can make holiday homes more attractive to travellers who want practical sustainability features without sacrificing convenience. They may also help older cottages, villas, apartments and Alpine chalets remain competitive in a changing accommodation market.

The greatest tourism value will be created when environmental improvements are explained clearly. Travellers need to know which features are available, how they operate and whether any restrictions apply. Specific information about solar power, charging access, public transport and recycling can be more useful than unsupported claims that a property is completely green.

Greener Stays Could Support Lesser-Known Destinations

Sustainable holiday homes may help tourism activity move beyond Europe’s busiest cities and resorts. Many rental properties are located in villages, mountain communities, coastal settlements and rural landscapes. When these homes are modernised with renewable energy and efficient facilities, they can become more attractive to travellers seeking quieter alternatives to heavily visited destinations.

Local economies may benefit when visitors stay in smaller communities and spend money at nearby restaurants, markets, attractions and transport services. Longer stays in self-catering accommodation may also create demand for local food and everyday services. However, such benefits were not measured by Interhome’s booking analysis and should be treated as possible effects rather than confirmed outcomes.

Improved public transport information and electric vehicle charging could make regional journeys easier. In Switzerland and France, charging facilities may support greener road trips through Alpine, countryside and coastal areas. In Italy and Spain, solar-equipped properties may strengthen the appeal of rural and seaside accommodation. In Germany, efficient holiday homes may support domestic travel across lake districts, coastal regions and smaller towns.

Tourism Growth Makes Resource Efficiency More Important

Europe’s accommodation market continues to operate at an enormous scale. More than three billion nights were spent in European Union tourist accommodation during 2024. During the first quarter of 2026, 471.1 million nights were recorded, representing growth of 3.4 per cent compared with the corresponding period of 2025.

As tourism expands, pressure can be placed on electricity networks, water supplies, waste systems and local transport. These pressures may become particularly visible during the peak summer season, when destinations receive large concentrations of visitors. Energy-efficient buildings, water-saving equipment, recycling systems and renewable electricity can help accommodation providers manage some of this demand more responsibly.

Sustainable properties cannot solve every tourism challenge. Crowding, housing pressure, transport emissions and excessive resource consumption may still be experienced. However, better-equipped holiday homes can form one practical part of a wider destination-management strategy.

Booking Data Will Need to Be Interpreted Carefully

Interhome’s figures show that qualifying sustainable properties captured a larger share of its summer reservations between 2020 and 2025. The share increased from 16.7 per cent to 29.5 per cent, while the overall number of sustainable bookings more than doubled. These findings demonstrate a clear change within the company’s analysed portfolio.

The results should not be presented as national market shares covering every accommodation provider. They also do not prove that sustainability was the deciding factor behind every reservation. Location, availability, price, property capacity and facilities may have influenced traveller choices at the same time.

No complete measurement of emissions, water savings or waste reduction was provided through the booking analysis. For that reason, the findings reveal changes in demand and property features rather than the total environmental performance of Europe’s tourism industry.

Europe’s Summer Accommodation Market Enters a Greener Phase

Italy led the analysed markets with a 40.1 per cent sustainable booking share in 2025. Germany followed with 36.1 per cent, while Switzerland reached 35.9 per cent. Spain recorded 29.3 per cent, and France stood at 16.1 per cent. Although development remained uneven, sustainable accommodation was given a stronger presence across all five markets.

Solar-panel availability was expanded particularly strongly in Italy and Spain. Electric vehicle charging recorded notable growth in Switzerland and France. Recycling facilities achieved the strongest overall increase among the examined property features. Together, these developments show how renewable energy, mobility and responsible resource use are being incorporated into the holiday-home experience.

The transformation is ultimately affecting more than booking percentages. Property investment is being influenced, greener journeys are being supported and travellers are being given more control over accommodation choices. As these changes continue, sustainable bookings are likely to play an increasingly important role in shaping how Switzerland, Italy, Germany, Spain and France compete for Europe’s future summer visitors.
