How to Travel Sustainably

Sustainable travel is not about guilt. It is about making choices that allow the places you visit to remain worth visiting — for the people who live there and for everyone who comes after you.

The Flight Question

Aviation is the largest single contributor to a traveller's carbon footprint. There is no way to make a long-haul flight green. But there are ways to reduce the damage. Fly direct when possible — takeoffs and landings burn the most fuel. Choose airlines operating newer, more efficient aircraft. Economy class has a lower per-passenger footprint than business. If you fly, make the trip count by staying longer rather than taking multiple short flights throughout the year.

Trains are the clear winner for distances under a thousand kilometres. Europe's rail network, Japan's Shinkansen, and expanding high-speed lines across Asia make overland travel both practical and pleasant. The journey becomes part of the trip rather than something to endure between destinations.

Where You Stay

Large chain hotels consume enormous amounts of energy and water. Smaller, locally owned accommodations tend to have a lighter footprint and put money directly into the community. Look for places that mention specific practices — solar power, rainwater collection, local sourcing — rather than vague claims about being eco-friendly.

Staying in one place longer reduces your overall impact. A week in a single city generates less waste than three days each in three cities with the transport between them.

How You Move

Walk first. Then public transit. Then bicycle. Rental cars and ride-hailing sit at the bottom of the list. Most cities worth visiting have public transport systems that work well once you understand them. Learning to navigate local buses and trains also connects you to how residents actually live.

What You Eat

Eat where locals eat. Markets, street food, and family-run restaurants source ingredients locally out of necessity rather than marketing. Eating lower on the food chain — grains, vegetables, legumes, fruits — carries a smaller footprint anywhere in the world. This is not a sacrifice in places like southern India, Lebanon, Ethiopia, or Mexico, where plant-based cooking is the tradition.

What You Buy

The most sustainable souvenir is one made by hand in the place you bought it. Mass-produced items sold in tourist shops are often manufactured thousands of miles away and shipped back. If you want to support local economies, buy directly from makers — ceramics, textiles, food products. Ask where something was made. The answer tells you where your money goes.

What You Leave Behind

Pack a reusable water bottle, a cloth bag, and a set of utensils. These three items eliminate most single-use waste generated by travellers. Refuse plastic bags, decline unnecessary packaging, and carry your waste until you find a proper bin.

The Larger Point

Sustainable travel is not a category of travel. It is a way of paying attention. The choices are small and cumulative — where you sleep, how you move, what you eat, what you carry. None of them diminish the experience. Most of them improve it.
