Sustainable Holiday Rentals Surge Across Major European Markets
Summer bookings for sustainable holiday homes have more than doubled since 2020, according to new data from rental specialist Interhome. The shift signals a structural change in consumer demand across Switzerland, France, Germany, Italy, and Spain as travelers prioritize eco-conscious property features for their vacation stays.

Property owners are responding by integrating specific eco-friendly upgrades to attract guests and reduce long-term costs. Recycling infrastructure saw the most significant cumulative growth across all surveyed markets. Regionally, France and Switzerland are seeing a rapid rise in electric vehicle charging stations, while Italy and Spain are outpacing others in the adoption of solar energy systems. Interhome CEO Jörg Herrmann noted that the company intends to use this recurring analysis to help shape the future of the rental market, providing property owners with concrete insights into evolving guest preferences.
