As of 2025, Canada has joined the ranks of Australia, Finland, Denmark, Sweden, Iceland, France, and a host of others in leading the charge toward sustainable tourism. This movement is marked by cities making significant strides in eco-friendly travel practices, committed either to minimizing their environmental footprints or to fostering responsible tourism that uplifts both visitors and local communities. In doing so, these cities are redefining the relationship between tourism and the environment, proving that unforgettable travel experiences can harmoniously coexist with ecological stewardship.
For the second year running, Helsinki has claimed the prestigious title of the world’s most sustainable tourist destination in the 2025 Global Destination Sustainability Index (GDSI). Developed by the Global Destination Sustainability Movement, the GDSI evaluates cities based on four key factors: destination management, supplier sustainability, social progress, and environmental performance. Notably, more than half of the top ten cities this year hailed from Scandinavia, showcasing its stronghold in sustainable tourism practices.
Helsinki’s sustained success is due, in part, to its ambitious sustainability initiatives. The Finnish capital reports that a remarkable 99% of its hotel rooms hold sustainability certifications, and over half of its electricity—54% to be exact—comes from renewable sources. The city is also on an impressive trajectory to reduce its carbon emissions by 80% by 2030, proving that it is possible to balance environmental concern with high-quality tourist offerings. Helsinki’s approach underscores the philosophy that sustainability and tourism can thrive together.
Central to its sustainability strategy is Helsinki’s commitment to transparency and accountability. The city has sought to transcend mere marketing claims, focusing on verifiable measures that guarantee genuine environmental benefits. It emphasizes reliable standards that assure every visitor leaves a positive legacy, making the city better than it was before their arrival.
Furthermore, Helsinki’s eco-conscious ambitions extend beyond the tourism sector. The city aims to protect 10% of its land and marine areas by 2038, a testament to its long-term vision for maintaining a pristine natural environment for generations to come. These efforts are integral to Helsinki’s mission of promoting responsible travel and mitigating the environmental repercussions often linked with tourism.
Following Helsinki in the rankings is Gothenburg, which secured the second spot, while Copenhagen rounded out the top three. Other Scandinavian cities, including Aalborg and Aarhus in Denmark, as well as Tampere in Finland, further highlighted the region’s dominance in the sustainable tourism landscape. The remainder of the top ten included Glasgow in the UK, Lyon in France, Belfast in the UK, and Reykjavik in Iceland, reinforcing a strong European influence in the rankings.
Europe’s presence in the 2025 index was striking, with three-quarters of the top 40 cities located on the continent. This statistic reaffirms Europe’s increasing commitment to sustainable tourism, as cities throughout the region embrace environmentally-friendly practices across varied sectors. Although Europe led the charge, notable advancements were also observed in cities outside the continent. Singapore claimed the 13th position, Goyang in South Korea landed at 15th, and Songkhla in Thailand followed closely at 28th. Japan’s Kumamoto took 33rd, reflecting a global shift toward sustainability.
Canada and Australia were prominently featured as well. Cities such as Montreal (20th), Quebec City (23rd), and Victoria (27th) showcased their leadership in sustainable tourism in Canada. Meanwhile, Australia’s Melbourne (11th), Brisbane (16th), and Sydney (25th) underlined a growing focus on sustainability within tourism in the Southern Hemisphere.
The UK made its mark too, with Glasgow taking fifth place, Belfast in ninth, and Manchester in 35th. Glasgow particularly stood out due to its robust sustainability measures, including having 97% of its electricity sourced from renewable energies and markedly progressing toward its 2030 carbon reduction goals. Additionally, the fact that 100% of its venues are sustainability certified played a critical role in achieving its high ranking.
The GDSI ranking serves as an essential benchmark for cities worldwide, establishing a standard for sustainable tourism practices. As travelers increasingly seek out environmentally-responsible options, the cities leading this index demonstrate how tourism and sustainability can coexist. They illustrate that it is indeed feasible to mitigate the negative consequences of tourism while enhancing visitors’ overall experiences—signifying that sustainability is not just a fleeting trend, but an imperative for the future of travel.
Canada’s inclusion alongside Australia, Finland, Denmark, Sweden, Iceland, France, and others marks a significant milestone in global sustainable tourism, as cities embark on a mission to set novel standards in eco-friendly travel.
In conclusion, the 2025 GDSI is a compelling reminder of the critical role cities play in shaping the future of tourism. By adopting sustainable practices in all facets of urban life, these cities are not only aiding the planet’s health but also enriching the quality of life for both residents and visitors alike. As the global tourism landscape continues to evolve, these cities are illuminating the path toward a sustainable future in travel.
