Some dreams come with a carbon price tag. Mine runs to over two tonnes of CO₂, the cost of a single return flight from Rio de Janeiro to Edinburgh, where this September I will study law for one semester. I have wanted this for years, and yet I cannot celebrate it without flinching: to chase a dream of learning, I must borrow from the very planet I claim to love. That tension is where my thinking on sustainable travel begins.
Brazil taught me this paradox long before any airport did. My country is almost unfairly blessed with the Amazon, the Atlantic Forest, the Pantanal, and the bay I grew up beside in Rio, and almost tragically careless with all of it. We are a nation that sells postcards of a paradise we are quietly burning. The Indigenous thinker Ailton Krenak names this wound precisely: in Ideas to Postpone the End of the World, he argues we have been convinced that we stand apart from nature, free to consume a planet we are in fact part of. We treat the river as a resource, he reminds us, when our ancestors knew it as a relative.
I want to travel as someone who remembers that the river is a relative.
So, honesty first: I will measure my flight’s footprint and offset it through projects certified under the Gold Standard or the Verified Carbon Standard, funding community-led Amazon preservation that returns the ecological cost to the forest the world depends on to breathe (SDG 13; SDG 15). The journey itself stays deliberate: the most direct routing available, a single light suitcase, no disposable convenience disguised as freedom. On the ground, that discipline becomes ordinary, a city crossed on foot, zero-waste study habits, plant-forward and local choices (SDG 12).
Then comes the part that outlasts the flight. As a future lawyer, my most valuable luggage is legal governance. I intend to study the enforcement mechanisms of Environmental Standards Scotland and the Circular Economy (Scotland) Act 2024, examining how a state legislates public-interest environmental accountability. Those frameworks are not souvenirs; they are tools I will bring back to Brazil, where the slow restoration of Guanabara Bay and the regulation of urban waste still wait for exactly this kind of legal backbone (SDG 11). The most sustainable thing a traveller can import is a better law, and the exchange runs both ways: I will carry Krenak’s question into Edinburgh’s classrooms and its river cleanups.
I will not pretend one semester abroad can be carbon-neutral. But a journey becomes a net positive when the traveller treats every trip as a loan from the future, borrowed with interest and repaid in care. I intend to return to Rio with more than a transcript. I will come back with frameworks, with fluency in how environmental accountability is enforced, and with Krenak’s stubborn hope: that we still have time to postpone the end of the world, one preserved relative at a time.
