The Explorer’s Ethical Imperative

The modern explorer is defined by a curiosity about the world, but that curiosity comes with an ethical imperative: to minimize our impact on the places we love. For European travel, this means confronting the elephant in the room: flying.

While flying is fast, it is also the single most carbon-intensive part of any journey. For the vast majority of intra-European travel, the plane is an unnecessary, environmentally costly choice. The train, by contrast, is the only ethical way to see the continent.


The Carbon Reality: Train vs. Plane

The data is clear. According to the European Environment Agency, a train journey emits, on average, 14 times less CO2 than a plane journey for the same distance.

Route (Example)

Mode of Transport

Approx. CO2 Emissions (per passenger)

Paris to Amsterdam

Plane

120 kg

Paris to Amsterdam

High-Speed Train

8 kg

Choosing the train is not a sacrifice; it is a powerful, tangible action that aligns your travel with your values.


ViaVia: Making the Ethical Choice the Easy Choice

ViaVia is built to make the sustainable choice the default choice. Our platform is designed to prioritize rail connections for all viable routes, ensuring that the ethical option is also the most convenient, comfortable, and scenic.

  1. Rail-First Route Optimization: Our algorithms automatically prioritize rail connections over short-haul flights for journeys under 8 hours, showing you the true cost (time, money, and carbon) of each option.

  2. The "In-Between" Advantage: The train facilitates the "Art of the In-Between," allowing you to break up long journeys with sustainable stops in smaller cities, further enriching your experience while reducing your overall footprint.

  3. The View: Let's not forget the intangible benefit. You can't see the Alps, the Tuscan vineyards, or the Norwegian fjords from 30,000 feet. The train offers a continuous, immersive experience that connects you to the landscape you are traversing.


The true explorer leaves only footprints. By choosing the train, you are choosing the only ethical way to see the continent.
