In a recent release, Interhome, a leading holiday rental management company in Europe, has unveiled its report titled "Sustainable Summer Booking Trends." This series aims to examine how sustainability within the vacation rental sector is evolving based on Interhome's own booking data. Notably, the report indicates a remarkable increase in sustainable bookings across key European markets, marking a significant shift in travel preferences among vacationers.

Key Findings of the Report

The analysis focuses on vacation stays scheduled from June to September and encompasses data from Switzerland, France, Germany, Italy, and Spain. The results are striking; sustainable summer bookings more than doubled from 2020 to 2025. During this same time frame, the share of sustainable bookings in Interhome's total summer reservations rose significantly from 16.7% to 29.5%, a notable 12.8 percentage point increase.

Further dissection of the data reveals varying trends across different markets. As of 2025, Italy led the way with the highest proportion of sustainable bookings at 40.1%, closely followed by Germany with 36.1% and Switzerland with 35.9%. In contrast, Spain recorded a lower share at 29.3% while France lagged behind with only 16.1%, indicating that different stages of development exist within these markets.

Advancements in Sustainability Characteristics

Among key sustainability features, recycling capabilities showed the most significant progress across all five markets from 2020 to 2025, particularly noticeable in France, Italy, and Spain. Additionally, electric vehicle charging stations revealed substantial advancements, especially in France and Switzerland. Solar panel installations also gained traction, most prominently in Italy and Spain. These diverse advancements underscore the varying paces of sustainable development in vacation accommodations across countries.

Jörg Herrmann, CEO of Interhome, commented on the findings, stating, "Our goal is not merely to react to changes in the vacation rental market but to help shape them. This series will offer periodic, data-driven insights that can facilitate a more informed discussion about the future of sustainable vacation rental management and travel."

Furthermore, Saskia Weber, Interhome's Director of Sustainability, emphasized the increasing investments property owners are making towards sustainability. This includes the installation of electric vehicle charging points to attract guests, as well as implementing photovoltaic systems and energy-efficient appliances to reduce operational costs. Weber pointed out that these sustainability efforts are fostering a growing number of eco-friendly accommodations within Interhome's portfolio, paralleling the rising share of sustainable summer bookings.
