The first thing we leave behind when we travel isn’t a review, a photograph, or a souvenir. It’s a footprint.
Some footprints are visible. Most are not.
Before preparing for my study abroad experience, I spent most of my time thinking about what I hoped to gain from travelling: new cultures, unfamiliar streets, conversations with people whose lives looked different from my own. Sustainability made me stop asking what I would take home and start asking a different question altogether: What will I leave behind for the place that welcomed me?
That question changed the way I think about travel.
Flying overseas will inevitably leave an environmental footprint. Pretending otherwise would be dishonest. Instead, I believe sustainable travel begins the moment we accept responsibility for every decision that follows. During my placement, I plan to rely on public transportation and walk whenever possible, carry reusable essentials, reduce unnecessary food and plastic waste, and intentionally support local businesses instead of defaulting to large international chains. I also want to research airlines investing in newer aircraft and sustainable aviation fuel because where we choose to spend our money quietly shapes the future we encourage.
What I appreciate about the United Nations Sustainable Development Goals is that they don’t exist in isolation. Choosing public transit isn’t only about reducing emissions under Climate Action (Goal 13). It also means participating in and supporting more sustainable cities under Goal 11. Buying from independent cafés, markets, and businesses isn’t simply about having a more authentic experience; it encourages more responsible patterns of consumption that reflect Goal 12. The more I read about sustainability, the more I realized these aren’t separate goals at all. They’re connected by one simple idea: every small decision leaves a ripple that reaches farther than we usually notice.
One idea has stayed with me throughout this process. Travelling shouldn’t only change the traveller. It should demonstrate respect for the destination. To me, that means leaving places as clean as I found them, appreciating communities without overconsuming them, and remembering that being a visitor is a privilege rather than a right.
Years from now, I probably won’t remember every train I took or every reusable bottle I carried. What I hope to remember is that I learned to travel differently. If someone visits the same places after me, I hope my presence is remembered not by what I left behind, but by how little I asked the world to carry on my behalf.
