Travelling more sustainably
This isn't about stopping travelling. It's about a few specific decisions changing the impact considerably, several of which also improve the trip.
What weighs most: transport
The long journey is most of almost any trip's impact, by a wide margin. Everything else (towels, straws, bags) is marginal by comparison. If you only change one thing, make it this.
Fewer, longer trips
A two-week trip pollutes considerably less than two one-week trips to the same place, because the flight happens once. And it works out cheaper per day. The most effective measure there is.
Rail where possible
For journeys up to six or seven hours, rail almost always beats flying on impact, and you arrive in the city centre. In Spain the high-speed network means many domestic journeys don't need a plane at all.
Direct flights
Take-off and landing are the most fuel-intensive parts, so a direct flight pollutes less than the same route with a stopover. And you avoid the risk of missing your connection.
Leave your money where you go
Staying in locally run places, eating in neighbourhood restaurants and hiring local guides keeps your spending in the community rather than with a chain. And you eat better and see more.
Avoid saturated places
Overtourism is a real problem: some cities have had to apply fees or capacity limits. Choosing the alternative destination or shifting your dates eases that pressure, and you enjoy it more because you don't queue.
Water and waste
In water-stressed destinations, short showers and skipping daily towel changes genuinely matter. And a reusable bottle saves dozens of plastic ones on a long trip.
What not to do
Feel guilty and give up. Travel done well sustains entire local economies and is one of the best ways to understand the world. It's about adjusting decisions, not renouncing them.
