The Finnish capital scores 92.94% in the 2026 Global Destination Sustainability Index, as 98% of its larger hotels hold environmental certification — but the more revealing story lies in the systems, partnerships and tourism strategy behind the score.
Europe (Tourism Reporter) — Helsinki has done something few destinations can claim: it has topped the Global Destination Sustainability Index three years in a row.
The Finnish capital took the number-one position in the 2026 rankings, released this week, extending a run that began in 2024 and putting it ahead of more than 100 cities included in the global comparison.
For a tourism sector in which sustainability leadership can shift as destinations introduce new initiatives, improve their infrastructure or strengthen their reporting, three consecutive first-place finishes suggest something deeper than a single successful year. They point to the ability to sustain policies, partnerships, investment and measurement over time.
And that distinction matters.
The GDS Index is not a popularity contest. It is a structured benchmarking programme that measures destination sustainability across four areas: environmental performance, social sustainability, supplier performance and destination management, using more than 70 indicators.
The 2026 results also show just how competitive the field has become. Helsinki scored 92.94%, followed by Gothenburg at 91.29% and Copenhagen at 90.35%. Across destinations assessed in both 2025 and 2026, 89% improved their scores, while the overall average reached a record 74.27%.
That makes Helsinki’s consistency particularly interesting.
The story is no longer simply that Helsinki is sustainable. It is that Helsinki has built a system capable of repeatedly measuring, managing and improving its sustainability performance.
The comparison does have an important qualification: participation is voluntary, so the GDS field consists of destinations that choose to take part in the benchmarking programme. But that does not make the comparison insignificant. The index is designed specifically to assess destinations willing to put their sustainability performance through a structured, evidence-based framework.
Helsinki’s own tourism leadership sees the three consecutive victories in similar terms.
“Securing the top position for the third consecutive year demonstrates that sustainability is not a one-off achievement but a long-term strategic commitment,” said Nina Vesterinen, Director of Tourism at the City of Helsinki. “This recognition reaffirms that Helsinki is moving in the right direction and inspires us to continue raising the bar.”
But there is another reason this year’s result is particularly interesting.
Helsinki’s sustainability credentials are arriving at a moment when destinations across Europe are being asked to prove more of what they claim.
The EU’s Empowering Consumers Directive is entering into application just as the 2026 GDS results are being published, putting greater emphasis on environmental claims being clear, substantiated and verifiable. Helsinki itself points to the GDS Index as one of the independent datasets that can help demonstrate measurable sustainability performance.
And that is where this story becomes bigger than another tourism ranking.
Helsinki may have won the sustainability race for a third consecutive year. The more important question is whether its model can withstand a new era in which tourism destinations increasingly have to prove their green credentials — rather than simply promote them.
A Ranking Arriving at a Pointed Moment for Sustainability Claims
The timing of this year’s result carries significance beyond Helsinki’s tourism calendar. The ranking arrives just as the European Union’s new Empowering Consumers Directive (EmpCo) enters into application, bringing greater scrutiny to environmental and sustainability claims. The directive is designed to tackle misleading or unsubstantiated green claims by requiring businesses to support sustainability assertions with evidence that can be independently verified. Generic claims such as “eco-friendly” or “green” cannot simply stand on marketing language alone.
For destinations — and the hotels, tour operators and attractions that collectively shape the visitor experience — that changes the calculus.
A destination that has spent years building measurable sustainability systems, securing environmental certifications and participating in external benchmarking enters this new regulatory environment with something increasingly valuable: evidence.
Helsinki’s three consecutive GDS Index victories therefore arrive at an interesting moment. The city has voluntarily subjected its tourism sustainability performance to the same broad benchmarking framework year after year, while the European regulatory environment is moving towards greater scrutiny of the evidence behind sustainability claims. Helsinki’s Tourism Director, Nina Vesterinen, explicitly connected the two developments, saying the GDS result provides proof that the city’s sustainability efforts are “not just words, but are measurable and verifiable”.
That distinction between rhetoric and substance runs through Helsinki’s tourism story.
And the numbers help explain why.
As many as 98% of Helsinki hotels with more than 50 rooms hold environmental certification, compared with a European average of just 10%, according to the GDS Index results.
That is not a small difference. It points to a hotel sector in which environmental certification has become deeply embedded across the larger-property market — an important piece of infrastructure behind Helsinki’s wider sustainable-tourism strategy.
It also connects directly to a story Tourism Reporter has examined before.
In our earlier report, “Helsinki: A Model for Sustainable Urban Tourism,” we looked at how the Finnish capital was moving beyond the traditional idea of sustainable tourism towards a broader model focused on how tourism can contribute positively to the city, its residents and its wider urban ecosystem.
The 2026 GDS result adds another layer to that story.
Helsinki is not simply collecting sustainability accolades. It is building a body of measurable evidence around the tourism system itself.
That may prove increasingly important as Europe’s sustainability conversation moves from “What do you claim?” to “Can you prove it?”
What Actually Sits Behind the 93% Score
A headline ranking is one thing. The more revealing story is what sits underneath the score.
Helsinki recorded 92.94% in the 2026 GDS Index — the highest score in this year’s field — but the number is not being treated by the city as a finish line. Helsinki’s own sustainability strategy emphasises continuous measurement, monitoring and improvement, while its regenerative tourism action plan explicitly acknowledges that the city is “not yet a finished product” from the perspective of sustainable tourism.
That matters because Helsinki’s third consecutive GDS victory is not simply the result of maintaining a reputation built in previous years. The city has continued adding new initiatives, measurement systems and tourism-sector partnerships to the framework behind its sustainability performance.
One of the most notable developments is Helsinki’s move into regenerative tourism, launched through a 2025–2027 action plan and developed with pilot companies and other local stakeholders. The ambition goes beyond reducing tourism’s negative impacts: the city wants tourism to contribute positively to the wellbeing of residents, culture and nature while creating new opportunities for tourism businesses.
At Suomenlinna, the UNESCO World Heritage sea fortress that anchors an important part of Helsinki’s cultural tourism offer, the city and the Governing Body of Suomenlinna have piloted projects designed to show visitors what preserving a World Heritage Site actually involves — and how visitors themselves can participate in maintaining and protecting it. The visitor is no longer simply being asked to look at heritage; the experience is beginning to explain what it takes to keep that heritage alive.
A second pilot brings the same philosophy into one of Helsinki’s most distinctive civic spaces. At the Oodi Central Library, the city has been testing the Helsinki-kaveri, or “Helsinki buddy”, concept, in which local residents act as guides and introduce visitors to the library’s extensive range of activities. On its own, it is a relatively small intervention. Strategically, however, it fits a wider pattern in Helsinki’s approach: turning sustainability into something visitors can experience through local people, culture and institutions rather than something that exists only in a destination’s back-office reporting.
Helsinki has also continued to build the verification layer around its tourism strategy. Earlier this year, the city received the national Sustainable Travel Finland (STF) label, adding a domestic sustainability credential to its international GDS recognition. The city says it has also engaged local tourism businesses in the STF programme, with more than half already holding the label.
Then there is the data.
In 2026, Helsinki published its first Helsinki Tourism Sustainability Report, covering 2024. The report brings together the current state of tourism sustainability, the city’s objectives and the indicators used to monitor progress. Helsinki says its reporting follows the VSME standard and supplements it with tourism-specific indicators drawn from frameworks including SF-MST, ETIS and GSTC.
That may be the most important part of the 92.94%.
The score itself is a ranking outcome. The more interesting story is the infrastructure underneath it: measurement, certification, reporting, business participation and experiments in how tourism interacts with residents, culture and place.
Helsinki is therefore doing something more sophisticated than simply trying to remain number one.
It is building a tourism system in which sustainability can increasingly be measured, verified, experienced and — crucially — improved.
That distinction becomes particularly important as European tourism enters an era in which sustainability claims face greater regulatory scrutiny.
And it brings us back to the question at the heart of Helsinki’s three-year run:
Is the city winning a sustainability ranking — or is it building a tourism model that can keep producing evidence of progress after the ranking changes?
That is where the 92.94% becomes much more interesting.
The Coalition Behind the Result: Why This Isn’t Just a City Hall Achievement
One of the more instructive aspects of Helsinki’s GDS performance is that the result cannot be reduced to what happens inside City Hall.
The GDS Index assesses not only destination-level performance but also the sustainability work of the tourism industry and the effectiveness of destination management. That makes private-sector participation an important part of the equation. A city can set ambitious policies, but its sustainability performance ultimately depends on what happens across the hotels, attractions, venues, transport providers and other businesses that make up the visitor economy.
Helsinki has responded by building structures for collaboration rather than leaving sustainability to individual businesses.
One of the clearest examples is Urban Climate Leaders in Tourism, a cooperation network established by Helsinki and Tampere with leading tourism companies. Eleven companies — including some of Finland’s largest hotel chains and major visitor attractions — joined the initiative with the shared goal of accelerating the transition towards a climate-neutral tourism sector. The network’s work is based on the UN-supported Glasgow Declaration on Climate Action in Tourism, and its members have committed to common goals and actions while working to improve how tourism’s climate impacts are measured and reduced.
The membership itself is revealing. Scandic Hotels, Sokos Hotels, Strawberry, Lapland Hotels, Suomenlinna, Linnanmäki, Korkeasaari and other major tourism operators sit within the same climate-action framework as the cities. That turns sustainability from a municipal policy objective into something closer to a shared operating agenda across the tourism value chain.
And the collaboration is not limited to setting targets.
The network has identified joint work around measuring tourism’s environmental impact, reducing emissions, preparing for climate change, sharing best practice and bringing more stakeholders into the process. It has also undertaken scenario work examining how tourism destinations can prepare for and adapt to the effects of climate change.
Helsinki has also built wider forums around sustainable tourism, bringing together organisations from outside the municipal structure, including Visit Finland, the Finnish Environment Institute, the University of Helsinki, accessibility and inclusion organisations and tourism-industry associations. The aim is to connect sustainability expertise across the public, private, academic and civic spheres rather than treating tourism sustainability as a single-department responsibility.
There is an important lesson here.
A destination cannot manufacture sustainable tourism demand through policy alone. It needs an ecosystem capable of delivering the promise once the visitor arrives.
That means the hotel needs to participate. The attraction needs to participate. The event venue needs to participate. Transport operators need to participate. And the destination management organisation needs to connect those efforts rather than allowing them to operate as isolated sustainability projects.
Helsinki’s model is therefore less about one city government imposing a sustainability agenda and more about building a coalition around a common tourism objective.
And that may be one of the less visible reasons the GDS result matters.
The 92.94% score belongs to Helsinki. But the work behind it is increasingly being distributed across the tourism ecosystem.
What This Means for Operators, Investors and the Travellers Choosing Between Cities
For tourism industry stakeholders deciding where to invest, expand, hold events or direct clients, Helsinki’s three-year GDS run offers a signal that goes beyond civic recognition.
Destination sustainability is increasingly becoming an operating issue, not simply a branding issue.
The relevance is particularly clear as European businesses face greater scrutiny over environmental claims. For operators working with destinations that already have established measurement, certification and reporting systems, the availability of documented sustainability data can provide a stronger foundation for their own procurement, reporting and communications. Helsinki’s GDS performance sits alongside other sustainability credentials, including its Green Destinations GSTC certification and the national Sustainable Travel Finland label, creating a broader verification framework around the destination.
For hotel groups and investors, the 98% environmental-certification rate among Helsinki hotels with more than 50 rooms is particularly notable. Compared with roughly 10% across Europe, it suggests that environmental certification has become a mainstream part of the larger-property market rather than a niche differentiator.
That changes the competitive baseline.
In a market where certification is already widespread, sustainability stops being an optional badge and starts becoming part of the expected product.
For a new hotel entering Helsinki, for example, the question is no longer simply whether certification could help differentiate the property. The more practical question is whether operating without an equivalent credential could leave the property behind its established competitive set — particularly when corporate buyers, event organisers and travel companies increasingly incorporate sustainability criteria into supplier selection.
The same logic applies to the MICE market.
Helsinki’s sustainability infrastructure is supported by collaboration between the city and tourism businesses, including the Urban Climate Leaders in Tourism network. The city says its wider sustainability work depends on active cooperation with companies, while the network brings tourism businesses together around climate action and shared objectives.
For event organisers and corporate travel buyers, that matters because destination sustainability is rarely delivered by one supplier. The hotel, venue, attraction, transport provider and destination organisation all form part of the same visitor journey.
A destination with established sustainability systems across that ecosystem can therefore offer something more useful than a green marketing slogan: a more coherent evidence base for buyers assessing the sustainability of an entire trip or event.
For travellers, the picture is simpler but still significant.
A high GDS score does not mean every hotel, restaurant or tour operator in Helsinki is automatically sustainable. The index measures destination-level performance across environmental, social, tourism-sector and destination-management dimensions; it should not be interpreted as a blanket certification of every tourism business. (hel.fi)
But Helsinki’s unusually high level of hotel environmental certification gives travellers a more tangible signal. Ninety-eight per cent of hotels with more than 50 rooms having environmental certification is a very different proposition from a destination where sustainability credentials remain largely dependent on individual marketing claims.
And that may be the broader shift underway in sustainable tourism.
The destination brand is becoming less about saying “we are sustainable” and more about building enough evidence for travellers, businesses and investors to decide whether that claim stands up.
For Helsinki, the three-year GDS run is therefore not simply another trophy.
It is becoming part of the destination’s commercial infrastructure.
Where Helsinki Goes From Here
Helsinki’s latest victory is being framed not as a finish line, but as leverage for the next phase of investment.
“This ranking proves that Helsinki can combine ambitious climate and sustainability targets with growth in tourism and events,” said Nina Vesterinen, Tourism Director at the City of Helsinki. “At the same time, it encourages us to continue investing in sustainable tourism – measures that strengthen the positive impacts of tourism on the city, its residents and the environment.”
That framing connects directly to Helsinki’s new Tourism and Events Development Programme 2026–2029, which places sustainability inside the city’s wider growth strategy rather than treating it as a parallel objective. The programme aims to accelerate year-round growth in tourism and events, extend the average length of stay, strengthen Helsinki’s international attractiveness and position the city as a stronger growth partner for the tourism and events industry.
That is an important distinction. Sustainability is not being presented as the opposite of tourism growth. It is being positioned as part of the mechanism through which Helsinki wants that growth to happen.
The logic is particularly interesting for a destination that still acknowledges the environmental cost of reaching the city. Helsinki’s own tourism leadership has noted that a large proportion of international visitors arrive by air or sea, while the city is seeking to attract more visitors from Finland and neighbouring European regions.
In other words, winning the sustainability ranking does not eliminate the hard questions created by tourism growth. It gives Helsinki a stronger platform from which to tackle them.
Vesterinen has also made clear that remaining at the top will require continued collaboration with the tourism and events industry and other stakeholders. “We are once again delighted with Helsinki’s great ranking, but at the same time it sets us high targets to remain at the top also in the future,” she said.
That collaborative emphasis may ultimately be the most transferable element of Helsinki’s approach.
The city’s result has not been built through municipal policy operating in isolation, nor through private-sector initiatives operating without public coordination. It has emerged from an architecture connecting city government, tourism businesses, industry coalitions, destination-management systems, site-level pilots, certification and measurement.
And that architecture now faces a different test.
Helsinki has spent several years building the systems that helped it reach the top of the GDS Index. The next challenge is to make those systems support better tourism growth: more year-round demand, longer stays, stronger visitor experiences and greater benefits for residents — without allowing growth itself to undermine the sustainability gains that produced the ranking.
That is a much harder proposition than simply winning an index.
With more than 100 cities participating in the GDS Index and European sustainability rules placing greater emphasis on evidence behind environmental claims, Helsinki’s third consecutive victory looks less like a ceiling and more like a new baseline for what a leading sustainable tourism destination is expected to demonstrate.
The real test now is not whether Helsinki can remain number one.
It is whether the systems that made it number one can help the city manufacture better tourism demand — and make that growth more valuable to visitors, businesses, residents and the destination itself.
That, ultimately, is where Helsinki’s sustainability story gets interesting for Tourism Reporter.
