Helsinki has retained its position at the very top of the Global Destination Sustainability Index (GDS Index) for 2025, confirming a European city’s sustained leadership in regenerative tourism. The index, which assesses more than a hundred destinations across roughly 70 indicators, ranks cities by four pillars: destination management, supply chains, social sustainability, and environmental performance. In Helsinki’s case, the proof of depth lies in concrete actions: a transparent climate roadmap for tourism, a comprehensive plan to measure tourism’s carbon footprint, and a robust network of environmentally certified hotels and tourism operators. The city’s approach is praised not only for reducing negative impacts but for actively increasing positive ones, leaving visitors and residents better off when a trip ends.
For Thai readers, the Helsinki story offers a practical mirror for how a tourism hub can balance growth with responsibility. Thailand has long welcomed visitors to its temples, markets, and coastlines, yet it also wrestles with overtourism pressures on popular spots, housing affordability for locals, and environmental strain from transport and infrastructure. Helsinki’s model suggests a path where sustainability is not a marketing line but a daily discipline—tested, audited, and visible to travelers. It raises questions Thai cities are already grappling with: how to cap and manage visitor flows without killing local economies, how to certify and support green practices across an entire tourism ecosystem, and how to measure success beyond glossy certificates.
Behind Helsinki’s ranking is a clear, data-driven commitment. The city measures the carbon footprint of tourism actively, charts a climate roadmap for the sector, and channels support to tourism businesses on the journey to greater sustainability. It also places strong emphasis on resident participation and well-being as essential components of sustainable tourism. The balance between guest satisfaction and local quality of life is treated as a shared outcome rather than a trade-off. “We are promoting tourism with all areas of sustainability in mind, reducing negative impacts and increasing positive ones,” explains Helsinki’s tourism director, underscoring a philosophy that local benefit is non-negotiable for the longevity of the sector. This sentiment echoes a growing global understanding that tourism policy must serve communities, ecosystems, and cultural heritage, not just visitor numbers.
An important dimension of Helsinki’s leadership is the high level of environmental certification across its hospitality sector. In Helsinki, a striking proportion of hotel rooms—particularly in larger properties—carry environmental certifications, signaling to guests that sustainability is operational, not optional. The city’s broader certification ecosystem extends beyond hotels to venues, conference facilities, tour operators, and related services. In March this year, Helsinki became the first city with more than half a million residents to earn the Green Destinations certification, a credential recognized by the Global Sustainable Tourism Council and regarded as among the most rigorous in the field. This external validation reinforces the city’s credibility and provides a clear benchmark for others.
Tourism growth in Helsinki has tracked the visible emphasis on sustainability. Early 2025 data from national statistics show a notable uptick in international tourism nights compared with the previous year, a reminder that responsible practice does not have to be a brake on growth but can be a competitive advantage in attracting travelers who want deeper, more meaningful experiences. Global travel surveys corroborate this trend: a large share of travelers say they seek responsible, low-impact experiences and are willing to adjust their plans to minimize climate harm. Helsinki’s experience suggests that when sustainability is embedded in policy, planning, and everyday operations, it can coexist with, and even enhance, visitor appeal.
For the Thai audience, Helsinki’s journey provides a set of learnings that could translate into local action. First, the importance of rigorous measurement and transparent reporting cannot be overstated. If Bangkok, Chiang Mai, or Phuket are to attract travelers who care about carbon footprints and community impact, it is essential to publish verifiable metrics on tourism emissions, energy use in hospitality, and local transport effects. Second, certification matters. The strong presence of certified, climate-conscious accommodations and operators signals to travelers that sustainability is more than a pledge—it is an investment in quality and reliability. Thai cities can explore scalable certification pathways that align with GSTC standards while simultaneously supporting small and mid-sized businesses through subsidies, training, and access to green financing. Third, the resident voice matters. Helsinki highlights resident well-being as a non-negotiable criterion; in Thailand, this translates into ensuring that tourism jobs offer stable wages, career development, and protections that shield communities from the volatility of seasonal demand.
There are, of course, multiple viewpoints worth weighing. Critics of destination-certification regimes point out that labels can become performative if not backed by rigorous monitoring and enforcement. In Helsinki’s case, officials emphasize that sustainability reporting must be credible and verifiable, not mere marketing. This stance aligns with broader European and global expectations that sustainability claims withstand scrutiny and demonstrate real, measurable progress. For Thai policymakers, the takeaway is clear: any expansion of sustainability labeling should be coupled with independent audits, transparent methodologies, and ongoing improvement plans that are accessible to the public. It is not enough to claim “green” status; travelers and residents must see the impact of measures in air quality, energy efficiency, waste reduction, and social inclusivity.
The Helsinki model also illustrates a broader geopolitical trend: sustainable tourism is aligning with climate action and local development in ways that can drive regional competitiveness. In Southeast Asia, where coastal destinations and cultural hubs attract millions, the question is how to sustain momentum while protecting unique ecosystems and cultural heritage. Helsinki demonstrates that success rests on four interlocking strategies: governance and leadership, credible measurement, market mechanisms (like environmental certifications), and community engagement. These pillars can inform Thai strategies such as integrating climate risk assessments into tourism planning, strengthening environmental standards across the hospitality sector, and fostering regional collaborations that share best practices and financing opportunities for green infrastructure.
From a cultural standpoint, the Helsinki example resonates with Thai values around family, community harmony, and reverence for institutions. The Thai tradition of collective decision-making within households and communities can be an asset in implementing sustainable tourism policies at the local level. In Buddhist contexts, the concept of mindful consumption and moderation dovetails with the idea of regenerative destination management: tourism that respects natural resources, supports local livelihoods, and practices transparently honest communication with visitors about environmental and cultural impacts. When Thai families choose travel destinations or decide where to spend leisure money, the growing presence of clearly credible sustainability signals—like certified accommodations or transparent carbon data—can influence choices in ways that strengthen both domestic and inbound tourism ecosystems.
What could be on the horizon for Thai communities and resorts? A few practical pathways emerge. First, anchor sustainable tourism in policymaking by linking it to national and local climate commitments, urban planning, and public transport investments. Second, scale up capacity-building programs that help small businesses attain and maintain environmental certifications, with government incentives and private sector partnerships. Third, develop destination-level dashboards that track key indicators—emissions, water use, waste, biodiversity health, and resident satisfaction—and publish them in accessible formats for travelers and citizens alike. Fourth, promote regenerative tourism experiences that give visitors opportunities to contribute positively, such as supporting local ecosystems, cultural preservation projects, and community-led enterprises. Finally, cultivate regional cooperation in the Association of Southeast Asian Nations context to share benchmarks, align certifications, and coordinate tourism investment—ensuring that sustainable travel benefits neighbors as well as domestic audiences.
The broader takeaway for Thai readers is that sustainable tourism is not a niche concern but a central component of resilience and long-term growth. Helsinki’s elevated status demonstrates that commitment, transparency, and community well-being can coexist with strong visitor demand. It offers a practical blueprint for cities like Bangkok and its periphery to rethink how tourism is managed, measured, and marketed. If Thai destinations adopt regenerative practices with clear accountability, the potential benefits extend beyond visitors to local communities, workers, and cultural heritage. The path forward may require courage in policy, investment in green infrastructure, and a shared cultural imagination about what a sustainable, respectful, and prosperous tourism sector looks like for Thailand in the coming decades.
In the short term, travelers can look for destinations that provide verifiable sustainability information, support ethically managed experiences, and choose accommodations with credible environmental certifications. For Thai families planning trips—whether within the country or abroad—there is value in considering not just the price or convenience of a stay, but the broader footprint of the journey and the benefits it yields for local communities. Collective choices, informed by transparent data and guided by a spirit of mindful travel, can help Thailand advance toward its own sustainable tourism goals while learning from Helsinki’s evident success.
