Travellers adapting to extreme weather

While generations take different approaches to more sustainable travel, adaptation to extreme weather and off-peak travel are becoming the new norms for all ages.

A study of 32,500 travellers by Booking.com reveals older generations take more concrete sustainable actions despite younger travellers expressing stronger environmental intentions.

• With 85% of travellers saying that more sustainable travel is important or very important to them, older generations demonstrate greater commitment to specific, more sustainable behaviours than their younger counterparts.

• 74% of travellers consider the risk of extreme weather both when choosing destination and timing of trips, and almost a third of travellers globally (31%) reported having to cancel or change trip plans as a result of it.

• 43% plan to avoid crowds, 42% plan to travel out of season and 25% plan to visit cooler destinations.

• In 2025, travellers booked more than 100 million room nights on Booking.com at accommodation partners with a third-party sustainability certification.

  
  

Although less than half (47%) of the Boomer survey respondents (61+), say they want to travel more sustainably in the coming 12 months, compared to 60% of Gen Xers (45-60), 71% of Millennials (29-44) and 75% of Gen Z (18-28), research shows that perhaps their actions speak louder than words. Because when it comes to the practical steps travelers are taking to be more sustainable, it seems older generations are more action oriented than younger ones:

• Of those who intend to travel more sustainably over the next year, two thirds of Boomers (67%) say they will reduce general waste when travelling compared to 56% of Gen X, 52% of Millennials and less than half of Gen Z (48%).

• 60% of Boomers intend to reduce energy consumption (such as turning off air conditioning and lights in their room when they aren’t there), compared to 51% of Gen X, 46% of Millennials and 42% of Gen Z.

• 59% of Boomers say they will shop more at local, independent stores on their trips compared to 50% of Gen X, 44% of Millennials, and 42% of Gen Z.

• And perhaps, unsurprisingly, older generations were much more likely to report plans to travel outside of peak season: Boomers (63%), Gen X (48%), Millennials (41%) and Gen Z (36%).

  
  

That said, there are some areas where younger generations lead on more sustainable behaviors, particularly when it comes to learning about local cultures, indigenous communities or the conservation of wildlife:

• Nearly a third of Gen Z (31%) and Millennials (29%) had participated in a tour or activity where they learned about or interacted with local indigenous people or cultures, compared to 23% of Gen X and 18% of Boomers in the last twelve months.

• And almost a quarter of Gen Z (24%) and Millennials (23%) had participated in a tour or activity that contributed to the health or conservation of the local ecosystem or wildlife, compared to 16% of Gen X and 9% of Boomers. 

  
  

Extreme Weather: A Concern for All Ages

While generations may differ on what they say versus what they do, extreme weather is actively reshaping travel choices and timings, becoming a significant consideration for all age groups. Nearly three quarters of all survey respondents said they consider extreme weather risk when choosing both destination (74%) and timing (74%). Globally 68% say they actively avoid destinations known for extreme weather, 55% find extreme weather stressful when booking a trip and 55% feel unpredictable weather makes it hard to know when to travel. 

Strikingly, almost a third of travellers globally (31%) reported having canceled or changed trip plans in the past 12 months due to extreme weather or natural disasters (e.g. high temperatures, storms, wildfires, floods, etc.). More than half of all those surveyed (55%) said that certain destinations had become too hot to travel to when they wanted to visit them, and that they had removed destinations from their travel wish list due to news of extreme weather or natural disasters (52%). Similarly, in a survey of 3,715 hotel and accommodation providers across 18 countries by Booking.com, 24% said they had also experienced operational disruptions due to extreme weather in 2025, and 40% of them had adjusted their operations in response to existing or potential climate-related risks such as heatwaves or storms.

Broader Understanding of More Sustainable Ways to Travel

The efforts properties are making to operate more sustainably is, in fact, of equal importance across all ages: with over a third of each age group saying they plan to stay at an accommodation which has a sustainability certification in the next 12 months: Boomers (35%), Gen X (35%), Millennials (36%) and Gen Z (35%). And it’s not just intent, recently released data shows that travellers booked 100 million room nights at properties with a third party sustainability certification in 2025 on Booking.com.

Alongside staying at properties that have a sustainability certification, and well-known behaviours like reducing waste, energy consumption and avoiding harm to wildlife, making conscious decisions about the timing and destination of trips are part of a broader understanding of how people plan to travel more sustainably in 2026.

Globally 43% of all travellers say they plan to avoid overcrowded tourist destinations (up 11% YoY), 42% plan to travel outside of peak season, and 25% will seek out destinations with cooler temperatures. Of those choosing quieter destinations, 44% state a desire to avoid contributing to overtourism, and 37% of those travelling outside of peak season want to reduce pressure on destinations, in line with a growing understanding of the impact of travel on communities as well as the environment.

"This year’s Travel & Sustainability Report shows that while generations may have different understandings of what constitutes more sustainable travel, adapting to extreme weather and actively avoiding crowds are now norms at all ages. We are encouraged by the broad range of ways travellers are already traveling more sustainably, and how they plan to continue.

"Whether that’s the 100 million room nights travellers booked with accommodation partners displaying a third-party sustainability certification on our platforms in 2025, using public transport or hiring an electric vehicle to get around on their trips, or indeed, choosing cooler and quieter destinations altogether. As a global leader in travel, we want to make it easier for both travellers and partners to continue to make these more sustainable choices so that everyone can continue to enjoy the benefits that travel brings, and that destinations can continue to be enjoyed by visitors and residents alike," said Danielle D’Silva, Director of Sustainability, Booking.com.
