Sustainable Tourism in 2026: Impact, Trends & Best Practices

As we move through 2026, sustainable tourism has stopped being a niche pitch and become the default operating question for destinations. UN Tourism counted 1.52 billion international travelers in 2025, a 4% jump on 2024, and the cities bearing the weight of that growth are rewriting their playbooks in public. Venice is charging day-trippers €5 to enter. Amsterdam is capping cruise ships. Barcelona is moving against short-term rentals. Booking.com’s 2025 sustainability research found that 75%+ of travelers want to travel more sustainably than they did the year before. The pressure is now from both sides: residents pushing back on overtourism, and travelers asking for a different kind of trip.

For destinations, sustainable tourism is the operating model that answers both. It’s not a values statement on a homepage. It’s a set of decisions about who visits, when, where they go, and how the local economy captures the value they bring. We’ve written this for the DMO directors, board members, and tourism marketers making those decisions, and we’ll point to specific cities and programs throughout, so you can see what’s actually working.

Understanding Sustainable Tourism

Sustainable tourism is the practice of growing or maintaining tourism without depleting what the visit depended on in the first place: the landscape, the culture, the local economy, the goodwill of residents. The UN Environment Programme’s working definition has held for almost two decades. Tourism that takes full account of its current and future economic, social, and environmental impacts, addressing the needs of visitors, the industry, the environment, and host communities.

The framework most destinations work from has three pillars. Get one wrong and the other two follow.

Environmental Integrity

Environmental integrity gets the most airtime, and rightly. Tourism accounts for roughly 8-10% of global greenhouse gas emissions, according to UNEP. But the destination-level work is less about carbon accounting and more about whether the next visitor degrades what brought the last one. That looks like Slovenia certifying 60+ destinations against the Green Destinations criteria, requiring measurable progress on energy, waste, and biodiversity before a town can use the label. It looks like The Icelandic Pledge, Inspired by Iceland’s eight-point commitment asking visitors to stick to marked paths, leave nothing behind, and not die for a photo.

The most California-specific version of this we’ve seen is Mono County’s “How to Poo Like a Pro in the Eastern Sierra”, a viral campaign that won the 2024 Visit California Poppy Award for Destination Stewardship and Sustainable Travel. The problem was unglamorous and real: too much human and dog waste left on backcountry trails and dispersed campsites. The campaign’s answer wasn’t a brochure. It was a video that treated outdoor-waste etiquette with the seriousness of any other piece of trip planning, complete with how-to instructions and the kind of dry humor that made people actually share it. The pledges and how-tos work because the data on whether you keep them shows up downstream: in trail erosion reports, in seabird nest counts, in repeat visitation.

Socio-Cultural Sustainability

Socio-cultural sustainability is what overtourism backlash forces a destination to confront. When Barcelona residents started spraying tourists with water guns in 2024, the underlying complaint wasn’t tourists per se. It was that the rent on their apartments had become a tourism input. Amsterdam’s “Stay Away” campaign told stag-party arrivals from the UK they were no longer welcome, and the city followed up with restrictions on short-term rentals and a cap on cruise ship arrivals. The destinations doing this well are clear-eyed about it: New Zealand’s Tiaki Promise asks visitors to commit to caring for the country, in writing, before they pick up a rental car. Palau makes you sign the Palau Pledge, stamped into your passport on arrival, before you’re admitted.

Socio-cultural sustainability also means ensuring a destination’s marketing reflects and uplifts its full community — including historically underrepresented groups. Our guide to how destination marketing organizations honor Black history examines how leading DMOs are building year-round programs, cultural trails, and community partnerships that celebrate African American heritage as a core part of the destination’s identity.

Economic Sustainability

Economic sustainability is the pillar that decides whether the program survives a board cycle. Tourism revenue that flows straight to international hotel chains and OTA platforms doesn’t pay for the trail maintenance the visit relied on. The destinations rebuilding this layer are pricing it in directly. Bhutan’s Sustainable Development Fee, currently $100 per visitor per day after a 2023 reduction from $200, funds free healthcare and education for citizens and gates the visitor count by design. Venice’s €5 day-tripper fee, introduced in 2024, isn’t going to fix overtourism by itself, but it gives the city a measurable hand on the demand lever it didn’t have before. Copenhagen’s CopenPay, launched in 2024, takes the opposite tack. It rewards travelers for low-impact behavior (taking a train instead of a flight, picking up litter, eating plant-based) with free experiences from museums and restaurants. The point in each case is the same. The destination is shaping economic flows, not just receiving them.

The Role of Sustainable Tourism in the Travel Industry

For a destination marketing organization, sustainable tourism isn’t a separate program. It’s a lens applied to every existing program: how the calendar is curated, which businesses get co-op marketing dollars, which content gets pushed in which season, where the visitor is sent when they arrive. Done well, it changes three things at once.

Promoting Environmental Stewardship

The DMO’s job isn’t to lecture visitors about their carbon footprint. It’s to make the low-impact path the easy one. Visit Faroe Islands ran “Closed for Maintenance, Open for Voluntourism” for several years, briefly shutting popular sites to all but volunteer travelers who’d help maintain them. The campaign got international press, and the underlying point was that the islands have decided which kind of visitor they want at scale. Slovenia’s Green Scheme is more bureaucratic but more durable. Certified destinations get co-marketing support and are featured in the country’s tourism board content. The path of least resistance for a Slovenian town is the sustainable one, because that’s the path the tourism board paved.

Supporting Local Economies

The data point destinations chase here is what share of visitor spend actually stays local. Bhutan’s high-value, low-volume model is the extreme version, but the principle scales down. Smaller DMOs do this with co-op marketing programs that route visitors to participating local businesses, food trails that anchor on independent restaurants rather than chains, and first-party data on which businesses are actually getting the foot traffic the campaigns promise. The reporting matters as much as the program. A sustainable tourism strategy that can’t show, by Q4, that local restaurants A through F captured measurable revenue from program X is a strategy that won’t survive the next board meeting.

Enhancing Visitor Experiences

The destinations and businesses winning at sustainable tourism aren’t selling restraint. They’re selling a better trip. Rush Creek Lodge & Spa at Yosemite turned this into a Poppy Award-winning program: “Trade Trash for Spa Treatments,” tied to the long-running Yosemite Facelift cleanup event. Guests bring in bags of trash from inside Yosemite National Park, and the lodge converts them into spa minutes, treatments, and stays. The program ran for years before Visit California recognized it for sustainability in 2023, and the reason it works is the same reason CopenPay works in Denmark: the sustainable behavior comes with an experience worth posting about, not a lecture. Costa Rica’s CST-certified hotels lean into the same proposition with a different vocabulary. The rainforest is the amenity. The DMO’s storytelling work is to surface those experiences and make the sustainable option also the one that’s worth posting about.

Underlying all of this is a commitment to excellent guest services — the systems and people that ensure every visitor interaction, from arrival to departure, meets or exceeds expectations. Destinations that invest here see higher satisfaction scores, stronger reviews, and the kind of word-of-mouth that no ad budget can replicate.

Technology and Real-Time Tools for Sustainable Tourism

Most of the destinations leading on sustainable tourism are leaning on technology to do work that brochures and signage can’t. The shape of it is the same across very different places: turn opaque demand into legible demand, so you can route, throttle, or redirect it.

Venice now requires day-trippers to book entry through an online portal that doubles as a real-time count of visitors in the city, with the €5 fee triggered above thresholds. Acadia National Park in Maine instituted a reservation system for Cadillac Mountain. You book your two-hour window in advance, and the park gets to manage the road’s capacity instead of absorbing whoever shows up. Glacier National Park did the same with vehicle reservations for Going-to-the-Sun Road. Each of these moves a destination from a posture of receiving demand to one of shaping it.

The other category is the digital pass: a phone-native way for a destination to direct visitor flows to participating businesses or off-peak times, capture first-party data on where people actually went, and replace stacks of printed brochures and trail maps. Adoption is increasingly the norm for destination marketing operations because it gives the DMO something the previous era of printed materials never did: a line of sight from the marketing campaign to the actual visit and the actual spend. Our piece on visitor experience platforms walks through how DMOs are building these stacks.

The Importance of Sustainable Tourism in 2026

The reason this question keeps getting asked, and keeps getting answered with three-pillar diagrams, is that the answer has actually changed in the last five years. Tourism’s growth post-pandemic has been sharper and more concentrated than the industry models predicted. UN Tourism counted that 1.52 billion international travelers in 2025, and the curve is steepening, not flattening. The same dozen cities are taking a disproportionate share. The same ecosystems are bearing the weight. The same residents are pushing back.

Sustainability in 2026 has also expanded to include resilience: the ability of a destination to absorb a shock and come back. The 2026 Visit California Poppy Award for Best Sustainability or Resilience went to Visit Pasadena for its response to the 2025 Eaton Canyon wildfire, which displaced thousands of residents and gutted tourism demand overnight. Visit Pasadena’s “Come Through” and “Meetings Bloom Stronger” campaigns shifted from promotional content to community support and storytelling, and by the time the data came in, average length of stay had increased by 26%. That’s a sustainability outcome in the post-2020 sense: not only protecting a destination’s natural assets, but rebuilding the visitor base after climate-driven disruption.

Preserving Natural and Cultural Heritage

Tourism is now the leading economic activity in roughly one in five of the world’s most-visited natural parks, according to UNEP. The math is unforgiving. Any erosion of the underlying landscape is also an erosion of the asset the destination is selling. Costa Rica’s CST framework (Certificación para la Sostenibilidad Turística) has been doing this for over two decades. Certified operators pay nothing for the certification itself but unlock co-marketing through the national tourism board and tax incentives tied to verified practices. The framework works because the incentive structure rewards the operators who steward the land they depend on. Cultural heritage is the same problem, one floor up. When Barcelona’s Sagrada Família, Kyoto’s geisha district, and Iceland’s Diamond Beach get overwhelmed, the experience that brought visitors there isn’t actually available anymore.

Ensuring Long-Term Economic Viability

Sustainable tourism doesn’t mean fewer visitors. It usually means a different mix. Bhutan’s $100/day fee model and Slovenia’s Green-certified destinations are both growing visitor revenue while constraining or reshaping volume. Future Market Insights projects the global sustainable tourism market to reach $1.06 trillion by 2034, growing roughly 13% annually, outpacing tourism as a whole. Travelers who actively select for sustainability tend to spend more per trip, stay longer, and return. The segment is more attractive economically, not less, and destinations that compete for it are competing for the most valuable subset of the tourism industry.

Contributing to Global Sustainable Development Goals

The UN’s 2030 Agenda explicitly names tourism in three of the Sustainable Development Goals: 8, 12, and 14. For a DMO presenting up to a city council or board, the framing matters. A sustainable tourism strategy isn’t only about the destination’s brand. It’s also a city or country meeting its own published commitments under those goals. New Zealand’s Tiaki Promise is the cleanest expression of this. The country has tied its visitor-facing messaging directly to its national identity and policy posture. Visitors don’t experience that as policy. They experience it as a request from the place itself.

Obstacles in Implementing Sustainable Tourism

The barriers to sustainable tourism implementation aren’t usually values disagreements. They’re operational: how do you ration a public good, who pays for the infrastructure, and what do you do when the easy money is sitting right in front of you.

Balancing Visitor Satisfaction and Conservation

Visitors don’t show up wanting to ruin the place. But the cumulative effect of a million individual visits, each of them perfectly reasonable, is what overwhelms a fragile ecosystem or a historic neighborhood. The destinations that handle this best don’t ask the visitor to make the trade-off in their head. They make the design choice upstream. The Faroe Islands’ reservation requirement at popular sites is one example. Bhutan’s high-fee, low-volume model is another. Both create satisfaction by ensuring the experience that draws visitors there is actually available when they arrive.

Managing Tourism Demand and Overtourism

Overtourism is the most public failure mode and the hardest to fix once it’s established. Amsterdam’s response (short-term rental restrictions, a cruise ship cap, the “Stay Away” ad campaign) is unusually direct. Most destinations are quieter about it. Croatia’s Dubrovnik moved to time-windowed cruise ship arrivals to keep the old town from going gridlocked daily. Bali introduced a $10 visitor levy in 2024 dedicated to cultural and environmental preservation. Hawaii is implementing a transient accommodations tax for climate resilience. Each of these is a different theory of action: cap supply, price demand up, redirect spend back into stewardship. None is universal. All beat doing nothing.

Overcoming Financial and Policy Barriers

The funding question is the one that derails most sustainable tourism programs. The capital costs are upfront. The returns are diffuse and arrive in different budget years. The destinations that have made it work have generally tied the funding stream directly to the visitor: visitor levies (Iceland, Bali, Venice), bed taxes earmarked for sustainability infrastructure (multiple US states), or sustainable-business co-op marketing pools funded by hotel association dues. The structural lesson: avoid funding sustainable tourism from general revenue, because it competes against everything else the city is trying to pay for. Tie it to the visitor and it stays tied to the visit.

How can your destination practice sustainable tourism?

A short, opinionated playbook based on what the destinations cited above have actually done:

  1. Make the low-impact path the default. Whether that’s a reservation requirement at fragile sites (Acadia, Glacier, the Faroe Islands), a fee that gates volume (Bhutan, Venice), or rewards for low-impact behavior (Copenhagen’s CopenPay, Rush Creek Lodge’s Trade Trash for Spa Treatments), the design choice belongs upstream, not in a brochure.
  2. Tie sustainable funding to the visit. Visitor levies and bed taxes earmarked for sustainability infrastructure outlast budget cycles. General-fund line items don’t.
  3. Certify, then market the certification. Slovenia and Costa Rica both do this. The point isn’t the certification itself. It’s that the destinations have created a co-marketing incentive that pulls operators toward verified practices.
  4. Direct visitors to participating businesses with first-party data. Whether that’s a digital pass, a curated trail, or a destination app, the value is the line of sight from marketing to actual visits and actual spend.
  5. Have an opinion in public. Amsterdam’s “Stay Away,” New Zealand’s Tiaki Promise, Palau’s Pledge, Mono County’s “How to Poo Like a Pro.” All of these say something specific about what kind of visitor a destination wants. The destinations that say it clearly attract the visitors who agree.

The destinations leading on sustainable tourism aren’t the ones with the longest values statements. They’re the ones running specific programs, measuring specific outcomes, and being willing to say no to demand they don’t want. The Visit California Poppy Awards are useful here as a tell. The sustainability winners year over year tend to be the destinations and operators that built one concrete, memorable program around a real local problem and then told the story of it. The work is operational. We work alongside DMOs building that operational layer, and if you’re rebuilding your sustainable tourism program, we’re here when you need us.

FAQ

Sustainable tourism is the practice of growing tourism without depleting what the visit depended on: the landscape, the culture, the local economy, the goodwill of residents. The UN Environment Programme’s working definition is tourism that takes full account of its economic, social, and environmental impacts on visitors, the industry, the environment, and host communities.

Environmental integrity (preserving the landscape and ecosystems), socio-cultural sustainability (respecting and protecting host communities), and economic sustainability (ensuring tourism revenue stays in the local economy long-term).

With 1.52 billion international travelers in 2025 according to UN Tourism, destinations are hitting limits faster than expected. Sustainable tourism gives destinations the tools (visitor caps, fee structures, certified operators, digital passes) to keep the assets that brought visitors there in the first place.

Internationally: Venice’s €5 day-tripper fee, Amsterdam’s cruise ship cap and short-term rental restrictions, Bhutan’s $100/day Sustainable Development Fee, Palau’s mandatory passport pledge, Copenhagen’s CopenPay program, Slovenia’s Green Scheme certifying 60+ destinations, and Costa Rica’s CST framework. In California: Visit Pasadena’s Eaton Fire recovery campaign, Mono County’s “How to Poo Like a Pro” outdoor-stewardship video, and Rush Creek Lodge’s Trade Trash for Spa Treatments program at Yosemite. The California examples are all recent Visit California Poppy Award sustainability winners.

Start with the funding model. Visitor levies or bed taxes earmarked for sustainability outlast general-revenue line items. Pair that with a certification framework (Slovenia and Costa Rica are the templates) and digital tools that direct visitors to certified participating businesses while generating first-party data on actual visits and spend.

Overtourism is the point where cumulative visitor demand outpaces a destination’s capacity to absorb it without degrading the experience for residents and future visitors. Destinations manage it three ways: capping supply (Amsterdam’s cruise ship cap, Dubrovnik’s time-windowed cruise arrivals), pricing demand up (Venice’s day-tripper fee, Bhutan’s daily fee), or redirecting visitors to off-peak times and locations through demand-spreading tools.
