Older Travelers Act More Sustainably Than Younger Ones, Booking.com Data Shows

A new Booking.com report finds that younger travelers talk the most about sustainable tourism but do the least about it — while older generations quietly lead on concrete action. The finding cuts against the conventional narrative that Gen Z will drive the sustainability transition in travel, and has direct implications for how properties position their green credentials.

The 2026 Travel and Sustainability Report, published April 20 and based on a survey of travelers across multiple markets, shows that 71–75% of Gen Z and Millennials say they want to travel more sustainably. But when it comes to actual behavior, Boomers and Gen X consistently outperform them. Those older cohorts report higher rates of waste reduction (59–67%), energy conservation (51–60%), shopping at local businesses (42–59%), and traveling off-peak (48–63%).

Booking.com describes this as a "generational paradox," though it mirrors a well-documented gap between stated preference and revealed behavior in consumer research more broadly.

What this means for operators

The headline sustainability number is striking: 100 million room nights were booked at certified sustainable properties on Booking.com in 2025. That is a supply-side signal worth noting — guests are actively filtering for certification, and properties without one are losing a measurable share of bookings.

Climate anxiety is also reshaping when and where guests travel. Seventy-four percent of respondents say extreme weather now factors into their destination and timing choices, and 31% have already cancelled or changed plans because of it. Forty-three percent say they plan to avoid overcrowded destinations — up 11 percentage points year-over-year — while 42% intend to travel outside peak season and 25% will actively seek cooler-climate destinations.

On the supply side, 40% of surveyed properties say they are already adjusting operations for climate risk, and 24% report having experienced operational disruptions because of it.

The practical angle

For operators, the data points to three adjustments worth considering. First, sustainability certifications have moved beyond greenwashing territory — they are generating a measurable demand signal. Properties that have not pursued one are leaving bookings on the table. Second, off-peak demand is growing: positioning availability and pricing for shoulder-season travelers addresses a segment that is explicitly expanding. Third, messaging around sustainability should probably be calibrated to the guest segment — older guests respond to concrete, practical credentials, while younger guests are more interested in cultural or conservation experiences tied to a stay.

The report also notes that 60% of local residents surveyed say tourism has a net positive impact on their community, suggesting that sustainable positioning can be framed around community benefit as much as environmental impact.

Booking.com says the report draws on traveler survey data alongside booking behavior from its platform, though the full methodology and sample sizes are not broken out in the press summary.
