Choosing to travel sustainably is changing how we explore the world. According to recent insights, 84% of global travellers now say sustainable tourism is on their agenda, and as we head towards January, interest in eco-friendly escapes is rising 🌳. This gave FlixBus the perfect opportunity to dig into the data 🤓

We analysed public datasets across air quality, recycling rates, EV charging availability, and cycling and pedestrian infrastructure to uncover the top eco-friendly cities in Europe. From car-free zones to world-leading bike culture, these destinations are laying the foundation for cleaner and greener trips.

If you’re ready to explore Europe with care, here are the cities setting the standard for eco-friendly travel 💚

1. Hamburg

Hamburg leads the way as Europe’s most eco-friendly city in our index, scoring 8.6 out of 10. This city sets an impressive benchmark across multiple sustainability pillars, particularly air quality and recycling, which reflects decades of commitment to green living.

The city’s dedication to clean mobility shines through the 217 public EV charging points within 10km of the city centre, making electric travel genuinely accessible for locals and visitors alike ⚡

Hamburg’s leafy waterfront setting offers the perfect environment for low-impact exploration. Over half of the city is made up of green or blue spaces, including the sprawling Planten un Blomen Park, the idyllic Japanese Garden, and the canals and lakes that weave through Hamburg’s unique neighbourhoods. 

Travellers seeking sustainable activities in Hamburg can follow the Elbe Cycle Route, take a solar-powered boat trip across the Alster, or walk the emerging “Green Network” - a visionary plan to connect the entire city through continuous park and nature corridors 🍃. With a blend of vibrant culture and eco-conscious design, Hamburg sets the standard for green city breaks in Europe.

2. Düsseldorf

Düsseldorf ranks second in our analysis, offering an impressive combination of clean air, strong recycling performance, and an exceptionally high walkability score of 8.1. It’s a city that gently invites you to take your time, wander, and breathe a little deeper 🌬️

The Rhine promenade is the jewel in Düsseldorf’s sustainable crown. This wide, car-free riverside walkway attracts cyclists, joggers, buskers, and sunset-seekers all year round.

3. Amsterdam

No eco ranking would be complete without Amsterdam - a city where cycling has long been a way of life 🚲.

Amsterdam’s charm comes alive in its green spaces and waterways. Vondelpark is home to lakes, meadows, and tree-lined paths that are ideal for a relaxing ride.

Green design and exploration go hand in hand in Amsterdam; from electric canal cruises to repurposed cultural hubs, there’s plenty for eco-conscious travellers to get involved with here.

4. Stuttgart

Stuttgart is a somewhat surprising eco hero. While it’s known globally for its automotive history, the city performs strongly across sustainability metrics, including air quality and recycling ♻️.

The city’s geography - a series of valleys surrounded by vineyards - provides a unique outdoor appeal. And while Stuttgart scored low for cycle tracks, its extensive public transport network and hiker-friendly trails more than make up for it 🥾. Visitors can traverse the Green U’s eight kilometres of recreational space, whiling away hours in Rosenstein or Hohenpark Killesberg parks.

Stuttgart also offers eco-friendly cultural attractions.

Combining riverside charm with a strong sustainability profile, Cologne performed well in our study for air quality and recycling. The city is also home to 20 EV charging points near the centre, and obtained a good walkability score, making eco travel here both easy and enjoyable.

How to travel more sustainably in 2026

Travelling sustainably doesn’t mean sacrificing comfort, spontaneity, or great experiences. It simply means travelling with intention to reduce your impact, without downgrading the journey. With more travellers prioritising eco-friendly options, now is the perfect time to rethink how you move, explore, and experience Europe. 

One of the easiest ways to lower your carbon footprint is by choosing ground transport over flights 🚍. Coaches in particular emit significantly less CO2 per passenger than planes or private cars, and FlixBus connects major European cities with a greener, more affordable alternative 💚. Whether you’re heading to Berlin for a long weekend or planning a cultural break in Brussels, travelling by coach is one of the simplest switches you can make.

Packing light also helps reduce emissions, and every kilogram counts 🎒. Lighter luggage uses less energy in transport, making minimal packing a meaningful sustainability win. Bringing reusable essentials like water bottles and tote bags can also cut down on waste, particularly if you’re exploring cities with bustling shopping districts and local crafts to commemorate your trip with.

Once you arrive in your destination, embracing the local green infrastructure can further decrease your footprint. Europe’s leading eco cities are built for mindful movement, with extensive walking routes, bike lanes, EV charging networks, and public transport systems 🚋

You can also embrace sustainable tourism by opting for locally run cafes, restaurants and shops, particularly those guided by fair and responsible supply chains. Many European cities now feature eco-conscious markets, second-hand boutiques, and plant-based eateries, helping visitors discover local culture in ways that are kinder to both people and the environment 🤩
