Sustainable Travel

Discover the world and protect it at the same time: eco-tourism, low-carbon travel and green destinations for conscious travellers.

How do you travel sustainably?

Travelling sustainably means going slower, more locally and more respectfully – for example by train instead of plane, staying longer and choosing local accommodation and guides. Leading destinations include Costa Rica, Slovenia, Sweden, the Azores, the Alps by train and Borneo. Unavoidable flights can be offset with reputable providers.

Why is sustainable travel important?

Tourism accounts for 8% of global CO2 emissions. At the same time, travel is one of the most enriching experiences we can have. The solution lies not in giving up travel but in travelling more consciously: slower, more locally, more respectfully.

Sustainable travel means enjoying the beauty of the world while helping to preserve it. It is about conscious choices: taking the train instead of the plane, staying in local accommodation, supporting the local economy and treating nature with respect.

This guide shows you the best destinations for sustainable tourism, gives practical tips for reducing your carbon footprint and proves that responsible travel can be just as exciting.
