The most important item in my suitcase was not my passport, laptop, or even the adaptor that somehow never fits the right socket. It was a reusable water bottle.
When I first began preparing for my international placement, I imagined sustainability as something grand: international treaties, climate summits, and ambitious government targets. But as my departure date approached, I realised that sustainability often begins with much smaller decisions.
My journey became a game of choices.
At the airport, I chose to refill my bottle instead of buying another plastic one. When booking travel, I compared routes and prioritised options with lower environmental impacts where possible. I packed light, knowing that lighter luggage contributes, however modestly, to reducing emissions. I carried reusable bags, avoided unnecessary waste, and made a conscious effort to use public transport once abroad.
None of these actions alone will solve climate change. Yet sustainability is rarely about a single heroic act. It is about thousands of people making thoughtful decisions every day.
Travelling internationally can seem at odds with environmental responsibility. Aircraft cross oceans, cities welcome millions of visitors, and tourism places pressure on local resources. However, sustainable travel is not about avoiding exploration; it is about ensuring that exploration leaves a positive legacy.
The United Nations Sustainable Development Goals remind us that global citizenship carries global responsibilities. Goals such as Responsible Consumption and Production (SDG 12), Sustainable Cities and Communities (SDG 11), and Climate Action (SDG 13) encourage travellers to think beyond their own experience and consider the communities and environments they encounter.
During my placement, I intend to support local businesses, minimise waste, rely on public transport where practical, and remain conscious of my environmental footprint. More importantly, I hope to bring these habits from New York to London. Sustainable travel should not end when a plane lands; it should influence how we live long after the journey is over.
My reusable water bottle has now travelled thousands of miles. It has crossed borders, sat through delays, and survived being dropped more times than I would like to admit. It is not a revolutionary invention, and it will not appear in any history books.
But it serves as a reminder that sustainability is not a destination. It is a habit.
And every journey, no matter how far it goes, begins with a choice.
