Tilos, a small island in Greece’s Dodecanese, is a model of sustainability in the Mediterranean by pioneering environmental innovation and choosing a model of growth founded on respect for nature and community.
As one of Greece’s smaller destinations, it is more manageable but also faces the infrastructure difficulties typical of islands of its size. Despite these challenges, Tilos is making a difference.
The island’s Mayor, Maria Kamma, describes the philosophy behind this success to the Athens-Macedonian News Agency (AMNA):
“The visitor who comes to Tilos is not just looking for a holiday, but a substantial experience. They want to get to know a place that consistently operates according to its values, to become part of a community that cares for the environment and highlights the authenticity of the Aegean. Thus, sustainability is not just a ‘green label,’ but the soul of our tourism.”
This path has already earned international recognition. In 2024, the Municipality of Tilos was honored in Budapest with the Grand European Award for Sustainable Development at the European Enterprise Promotion Awards (EEPA). The island stood out among 442 entries from 29 countries, claiming first place in the sustainable development category with its Just Go Zero Tilos program, as well as the institution’s top Grand Jury Award.
This distinction elevates Tilos to a member of the European jury for the EEPA this year, an experience which, as Ms. Kammas notes, is “unique and at the same time a responsibility.”
“Our vision is a tourism that does not alter, but enhances the place; one that creates opportunities without exhausting resources. A tourism that keeps the soul of Tilos alive,” she adds. “For us, sustainability is not a goal to be achieved, but a path to be continued, guided by the love for our homeland.”
Tilos: From energy autonomy to “zero waste”
Tilos is the first island in the Mediterranean to implement a hybrid energy system using wind and solar power, combined with storage, achieving a high degree of energy autonomy. According to the mayor, this project was the start of a broader sustainability strategy that now touches every aspect of daily life.
“I am very proud of what we have achieved,” Kamma told Greek Reporter recently. “Our success is a lesson for all island communities in Greece.”
By producing its own power, derived from renewable energy sources, the island has significantly reduced its own carbon footprint while simultaneously reducing the costs carried by local people.
The next major step was the Zero Waste Tilos initiative, which made the island the first globally certified “Zero Waste” island. In practice, Tilos operates a waste management system where nothing is wasted: materials are collected separately, recycled or reused, and the amount sent to landfill is minimized.
This effort relies on the collaboration of the municipality with residents and businesses, ensuring daily life operates in a circular and environmentally friendly manner.
As the mayor points out to AMNA,
“In Tilos, sustainability is not just a word; it is a way of life. We chose development with respect for nature and community, showing that tourism can be based on quality, not quantity. Energy autonomy, protection of the natural environment, recycling, and mild forms of hospitality create a place that inspires visitors and makes them participants.”
The Greek island that balances nature and visitors
The small island, home to 591 permanent residents, hosts about 38,000 visitors each year during the tourist season, from April to October. The 85 businesses operating on the island—mainly eateries and accommodation—function with the awareness that their success depends on preserving the natural wealth.
Thus, development is focused not on over-construction but on enhancing quality and authenticity. Many of the visitors are repeat tourists, people who have been returning for decades, having built a special bond with the island and its people. Additionally, 48 kilometers of marked trails attract hikers and nature lovers seeking a quiet spot away from mass tourism.
The entirety of Tilos has been designated a Special Protection Area (SPA) under the EU Birds Directive, as it is home to 400 plant species and over 100 bird species across 16 different ecosystem types. This natural wealth, combined with the local community’s consistent environmental stance, has established the island as a model of sustainable tourism for the entire Mediterranean.
A European example
The tourist arriving in Tilos is looking for more than just sun and sea; they seek to participate in a lifestyle that respects the place and its people. As Mayor Maria Kammas says,
“Sustainability becomes our best ‘promotion’ because it gives meaning to the travel experience and ensures that Tilos will remain vibrant and hospitable for future generations.”
The case of Tilos demonstrates that sustainable development is a viable goal for more and more destinations. This small Dodecanese island succeeded in showing that the green transition is not theory but action, beginning at the local level and capable of inspiring an entire continent.
